Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

How DAO users can truly control their voting rights

How DAO users can truly control their voting rights
https://blockchaintopbuzz.medium.com/how-dao-users-can-truly-control-their-voting-rights-f945c9c6b65e
Aelf proposed a solution that gives the control of the voting rights back to users by classifying token permissions.
As of today, there are still few complete businesses. In addition to mining and building trading platforms, it is difficult to create a complete business model. Moreover, various trading platforms have gradually grown into enterprises with comprehensive products in the blockchain industry, including wallets, nodes, lending, mining pools, etc.
At the same time, cloud services can reduce the cost of building small exchanges, but they can also lead to big trading platforms monopolizing data. For example, some Internet companies provide free cloud services in order to collect more valuable data.
Currently, Ethereum, which has the richest DeFi ecosystem, is gradually upgrading to V2.0, and its consensus protocol will also be upgraded to PoS. Governance voting can be regarded as the most important feature in the PoS ecosystem.
This year, Yearn.Finance rose to sudden prominence. But due to the governance problem, its community members initiated a hard fork, resulting in YFII. Another DeFi project, YAM, had a unfixable rebase function error. The founding team apologized for the error and announced a ‘Migration Plan’, which will turn the project over to the community.
For a while, governance voting became all the rage. However, the increasingly bigger trading platforms have been criticized by users in governance voting. Is there a proper solution to handling the relationship between the trading platform and governance voting?

What will we lose when trading platforms monopolize the blockchain industry?

In June 2018, during the BP node election before the EOS mainnet launch, node voting began to have a crisis of confidence between token holders and the trading platform. it is widely believed that the top 20 holders of trading platform wallets held about 40% of all the EOS in circulation.
Since then, many trading platforms have enabled the “User Authorization” interface. EOS holders can authorize the token voting rights to the trading platform, who will vote on behalf of the users. The rule caused a backlash from users, forcing these trading platforms to change the rule immediately so that EOS holders could vote on their preferred BP nodes.
After the EOS BP node votes, whether the trading platform has the token voting right has been occasionally discussed, but fewhave noticed it.
Two years later, Justin Sun, founder of TRON, made a commercial acquisition of Steemit, a decentralized social networking platform. After the acquisition was announced, the Steemit community launched a soft fork to resist the project being controlled by TRON. However, Justin Sun voted with the support of trading platforms such as Binance, Huobi and Poloniex to prevent a soft fork.
After being questioned by users, Binance and Huobi said that they would no longer interfere in the voting of the Steemit community. However, hkdev 404 of the Steem community again reveived votes from Huobi accounts. It is said that nearly 40 million votes were cast during the incident, accounting for about 10% of the total circulation of STEEM tokens.
There is no doubt that when the trading platform monopolizes the industry, we will lose our voting right.
How do we defend our voting rights
The fact that the ownership of the tokens belongs to the holders is indisputable, but what about the voting rights of the tokens deposited on the trading platform? How can we defend our voting rights after trading platforms have monopolized the industry?

Trading Platform Model

Traditional centralized trading platforms will assign to each user a separate deposit address. After depositing, the depositedamount will be added into the cold wallet and hot wallet. When users want to withdraw their tokens, the trading platform will transfer the tokens out of the hot wallet. If there is insufficient balance in the hot wallet, then the tokens will be transferred from the cold wallet to the hot wallet, and then be withdrawn.
Under the traditional centralized trading platform model, once users transfer their tokens into a trading platform, it means thetoken ownership (including voting rights) is also transferred to that trading platform.
The aelf solution: classify token permissions and claim back voting rights
For the issue of “voting rights” between token holders and centralized trading platforms, aelf, a decentralized cloud computing blockchain network, has proposed a solution: to establish an aelf Centre Asset Management Contract on the chain. The contract can limit the funds entering the exchange and define different permissions to control the assets.
The main feature of the aelf Centre Asset Management Contract is to create the “Main Virtual Address of the Trading Platform”.
Each exchange has a main virtual address, which can only be used for transfer operation, but not for voting, trading and other operations. As a result, the exchange cannot misappropriate users’ assets for voting. At the same time, the assets of the primary virtual address are publicly available on the chain, which makes it more difficult for the exchange to misappropriate assets.
At the same time, the aelf Centre Asset Management Contract also has the function of “address definition”. The exchange can open different permissions to different addresses, such as opening different permissions according to the amount, transactions exceeding a certain amount can only be given the greenlight by using multiple signatures, and the assets can be frozen through the contract when the assets of the trading platform are stolen, etc.
For the users of the trading platform, the access of the trading platform to the aelf Center Asset Management Contract function will not undermine user experience. The virtual system address of the aelf Center Asset Management Contract will assign a virtual address to each user, which offers the same user experience as the traditional mode.
For the trading platform, each deposit address constructed by the virtual address system is generated by the algorithm and does not need to be carried out on the blockchain. This means that the trading platform does not need to manage a large number of private keys, and there is no risk that the private keys will be lost.
On the most important “voting rights” issue, the aelf Center Asset Management Contract will assign to each user a separate virtual address for voting:
Voting address = Hash (Exchange Main Address + Token + “VOTE”)
Voting process: the tokens are transferred from the main virtual address of the exchange to the special “voting address” for voting, and are then voted. After voting, the tokens are withdrawn from the voting address back to the main virtual address.
We can see that the aelf Centre Asset Management Contract proposed by aelf can improve the efficiency of the trading platform without affecting user experience. In addition, it solves the problem that users would lose their voting rights.
According to the data on Crypto Mode, the market value of PoS tokens has exceeded $33 billion without counting Ethereum. In the field of crypto, it is the biggest ecosystem next to Bitcoin. The most important function of PoS is vote staking. faced with bigtrading platforms, if the status quo continues, retail investors will gradually lose their “voting rights” that belong to them.

Comparison of Market Value of PoS tokens (Source: Crypto Mode)
The emergence of DAO offers an alternative to trading platforms who misappropriate users’ tokens, but it still can not change this situation. Of course, DAO will not die out. Small communities will still use DAO for community governance. The idea behind the design of aelf is to start from the underlying trading platform and solve this issue at the source. Whether the solution can work still takes time. However, as a member of the crypto industry, we should understand the importance of “voting rights”, and cannot allow the exchange to seize our rights at will.
Recently, aelf has also announced its DeFi plan, which includes a new blockchain 3.0 project with a large number of new technical features, such as cross chain function, virtual address and cloud services. Aelf also proposed a set of interoperability solutions with ERC-20 tokens. It can directly access the ETH ecosystem, allow ETH-based applications and wallets to directly access it, and maintain the interoperability with ETH. And aelf will provide a high-performance smart contract operation platform and cloud services that can support cross chain interaction. Users on major cloud servers can easily run aelf’s services and adjust the scale of cloud according to their own business needs.
The implementation of a slew of tools, cloud services and interoperability solutions developed by aelf means that centralized transactions can be directly connected to the aelf network, realizing one-click adaptation to the DeFi ecosystem. With aelf, CeFi and DeFi are able to learn from and complement each other.

Update TKEYSPACE 1.3.0 on Android

Update TKEYSPACE 1.3.0 on Android

https://preview.redd.it/6w93e0afttx41.png?width=1400&format=png&auto=webp&s=c00989612ec2d52eb522405e6b6a98bf875e08bb
Version 1.3.0 is a powerful update to TkeySpace that our team has been carefully preparing. since version 1.2.0, we have been laying the foundation for implementing new features that are already available in the current version.
Who cares about the security and privacy of their assets is an update for you.
TkeySpace — was designed to give You full control over your digital assets while maintaining an exceptional level of security, which is why there is no personal data in the wallet: phone number, the email address that could be compromised by hackers — no identity checks and other hassles, just securely save the backup phrase consisting of 12 words.

Briefly about the TkeySpace 1.3.0 update :

  • Code optimization and switching to AndroidX;
  • New section-Privacy;
  • Built-in TOR;
  • Selecting the privacy mode;
  • Selecting the recovery method for each currency;
  • Choosing the address format for Litecoin;
  • Enhanced validation of transactions and blocks in the network;
  • Disk space optimization;
  • Accelerated syncing;
  • Checking “double spending”;
  • The bloom filter to check for nodes;
  • Updating the Binance and Ethereum libraries;
  • A function to hide the balance;
  • Advanced currency charts;
  • Access to charts without authentication;
  • News section;
  • Browser for Tkeycoin;
  • Independent Commission entry for Bitcoin;
  • New digital currencies;
  • Digital currency exchange tab.

Code optimization and switching to AndroidX

A lot of work has been done on optimizing the code to speed up the application, improving the logic, synchronization speed, calculating the hash of cryptocurrencies, and successfully switching to AndroidX.

https://preview.redd.it/h3go5tzgttx41.png?width=1100&format=png&auto=webp&s=bf311efc73e3577c80f06a21d6b9317bb93ae989

New section: Privacy

  • Enable Tor;
  • Blockchain transaction (the selection of the privacy mode);
  • Blockchain recovery (choosing a recovery method);
https://preview.redd.it/iydfwuhittx41.png?width=1080&format=png&auto=webp&s=2ce7c489d893a2ab6b9d6fede57d8b94404edcfb

TOR

Starting with the current update, the TkeySpace wallet can communicate via the TOR network, includes new privacy algorithms, and supports 59 different currencies.

https://i.redd.it/kn5waeskttx41.gif
Tor is a powerful privacy feature for those who own large assets or live in places where the Internet is heavily censored.
Tor technology provides protection against traffic analysis mechanisms that compromise not only Internet privacy, but also the confidentiality of trade secrets, business contacts, and communications in General.
When you enable TOR settings, all outgoing traffic from the wallet will be encrypted and routed through an anonymous network of servers, periodically forming a chain through the Tor network, which uses multi-level encryption, effectively hiding any information about the sender: location, IP address, and other data.
This means that if your provider blocks the connection, you can rest easy — after all, by running this function, you will get an encrypted connection to the network without restrictions.

https://preview.redd.it/w9y3ax4mttx41.png?width=960&format=png&auto=webp&s=972e375fc26d479e8b8d2999f7659ec332e2af55
In TOR mode, the wallet may work noticeably slower and in some cases, there may be problems with the network, due to encryption, some blockchain browsers may temporarily not work. However, TOR encryption is very important when Internet providers completely block traffic and switching to this mode, you get complete freedom and no blocks for transactions.

Confidentiality of transactions (the Blockchain transaction)

The wallet can change the model of a standard transaction, mixing inputs and outputs, making it difficult to identify certain cryptocurrencies. In the current update, you can select one of several modes for the transaction privacy level: deterministic lexicographic sorting or shuffle mode.

Mode: Lexicographic indexing

Implemented deterministic lexicographic sorting using hashes of previous transactions and output indexes for sorting transaction input data, as well as values and scriptPubKeys for sorting transaction output data;
We understand that information must remain confidential not only in the interests of consumers but also in higher orders, financial systems must be kept secret to prevent fraud. One way to address these privacy shortcomings is to randomize the order of inputs and outputs.
Lexicographic ordering is a comparison algorithm used to sort two sets based on their Cartesian order within their common superset. Lexicographic order is also often referred to as alphabetical order or dictionary order. The hashes of previous transactions (in reverse byte order) are sorted in ascending order, lexicographically.
In the case of two matching transaction hashes, the corresponding previous output indexes will be compared by their integer value in ascending order. If the previous output indexes match, the input data is considered equal.

Shuffle Mode: mixing (random indexing)

To learn more about how “shuffle mode” works, we will first analyze the mechanisms using the example of a classic transaction. Current balance Of your wallet: 100 TKEY, coins are stored at different addresses:
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
Addresses in the blockchain are identifiers that you use to send cryptocurrency to another person or to receive digital currency.
In a classic transaction, if you need to send, for example, 19 TKEY — 100 TKEY will be sent to the network for “melting” coins, 19 TKEY will be sent to the Recipient, and ~80.9 TKEY will return to the newly generated address for “change” in your wallet.

https://preview.redd.it/x595qwdottx41.png?width=806&format=png&auto=webp&s=d9c2ae5620a3410ed83f7e16c018165c8ab35844
In the blockchain explorer, you will see the transaction amount in the amount of 100 TKEY, where 80.99999679 TKEY is your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee. Thus, in the blockchain search engine, most of your balance is shown in the transaction.

How does the shuffle mode work?

Let’s look at a similar example: you have 100 TKEY on your balance, and you need to send 19 TKEY.
x1. Address-contains 10 TKEY. x2. Address-contains 20 TKEY. x3. Address-contains 30 TKEY. x4. Address-contains 15 TKEY. x5. Address-contains 25 TKEY.
You send 19 TKEY, the system analyzes all your addresses and balances on them and selects the most suitable ones for the transaction. To send 19 TKEY, the miners will be given coins with x2. Addresses, for a total of 20 TKEY. Of these, 19 TKEY will be sent to the recipient, and 0.99999679 TKEY will be returned to Your new address as change minus the transaction fee.

https://preview.redd.it/doxmqffqttx41.png?width=1400&format=png&auto=webp&s=5c99ec41363fe50cd651dc0acab05e175416006a
In the blockchain explorer, you will see the transaction amount in the amount of 20 TKEY, where 0.99999679 TKEY is Your change, 19 TKEY is the amount you sent and 0.00000321 is the transaction fee.
The shuffle mode has a cumulative effect. with each new transaction, delivery Addresses will be created and the selection of debit addresses/s that are most suitable for the transaction will change. Thus, if you store 1,000,000 TKEY in your wallet and want to send 1 TKEY to the recipient, the transaction amount will not display most of your balance but will select 1 or more addresses for the transaction.

Selecting the recovery method for each digital currency (Blockchain restore)

Now you can choose the recovery method for each currency: API + Blockchain or blockchain.
Note: This is not a syncing process, but rather the choice of a recovery method for your wallet. Syncing takes place with the blockchain — regardless of the method you choose.
https://preview.redd.it/gxsssuxrttx41.png?width=1080&format=png&auto=webp&s=cd9fe383618dda0e990e86485652ff95652a8481

What are the differences between recovery methods?

API + Blockchain

In order not to load the entire history of the blockchain, i.e. block and transaction headers, the API helps you quickly get point information about previous transactions. For example, If your transactions are located in block 67325 and block 71775, the API will indicate to the node the necessary points for restoring Your balance, which will speed up the “recovery” process.
As soon as the information is received, communication with the peers takes place and synchronization begins from the control point, then from this moment, all subsequent block loading is carried out through the blockchain. This method allows you to quickly restore Your existing wallet.
‘’+’’ Speed.
‘’-’’ The API server may fail.

Blockchain

This method loads all block headers (block headers + Merkle) starting from the BIP44 checkpoint and manually validates transactions.
‘’+’’ It always works and is decentralized. ‘’-’’ Loading the entire blockchain may take a long time.

Why do I need to switch the recovery method?

If when creating a wallet or restoring it, a notification (!) lights up in red near the selected cryptocurrency, then most likely the API has failed, so go to SettingsSecurity CenterPrivacyBlockchain Restore — switch to Blockchain. Syncing will be successful.

Selecting the address format

You can choose the address format not only for Bitcoin but also for Litecoin. Legacy, SegWit, Native SegWit. Go to SettingsManage WalletsAddress Format.

Working at the code level

Enhanced validation of transactions and blocks in the network

Due to the increased complexity in the Tkeycoin network, we have implemented enhanced validation of the tkeycoin consensus algorithm, and this algorithm is also available for other cryptocurrencies.

What is the advantage of the enhanced validation algorithm for the user

First, the name itself speaks for itself — it increases the security of the network, and second, by implementing the function — we have accelerated the work of the TkeySpace blockchain node, the application consumes even fewer resources than before.
High complexity is converted to 3 bytes, which ensures fast code processing and the least resource consumption on your device.

Synchronization

The synchronization process has been upgraded. Node addresses are added to the local storage, and instant synchronization with nodes occurs when you log in again.

Checking for double-spending

TkeySpace eliminates “double-spending” in blockchains, which is very valuable in the Bitcoin and Litecoin networks.
For example, using another application, you may be sent a fake transaction, and the funds will eventually disappear from the network and your wallet because this feature is almost absent in most applications.
Using TkeySpace — you are 100% sure that your funds are safe and protected from fraudulent transactions in the form of “fake” transactions.

The bloom filter to check for nodes

All nodes are checked through the bloom filter. This allows you to exclude fraudulent nodes that try to connect to the network as real nodes of a particular blockchain.
In practice, this verification is not available in applications, Tkeycoin — decided to follow a new trend and change the stereotypes, so new features such as node verification using the bloom filter and double-spending verification are a kind of innovation in applications that work with cryptocurrencies.

Updating the Binance and Ethereum libraries

Updated Binance and Ethereum libraries for interaction with the TOR network.

Interface

Function — to hide the balance

This function allows you to hide the entire balance from the main screen.

Advanced currency charts and charts without authentication

Detailed market statistics are available, including volumes, both for 1 day and several years. Select the period of interest: 1 day, 7 days, 1 month, 3 months, 6 months, 1 year, 2 years.
In version 1.3.0, you can access charts without authentication. You can monitor the cryptocurrency exchange rate without even logging in to the app. If you have a pin code for logging in, when you open the app, swipe to the left and you will see a list of currencies.

News

In the market data section — in the tkeyspace added a section with current news of the cryptocurrency market.

Blockchain Explorer for Tkeycoin

Transaction verification for Tkeycoin is now available directly in the app.

Independent Commission entry for Bitcoin

Taking into account the large volume of the Bitcoin network, we have implemented independent Commission entry — you can specify any Commission amount.
For other currencies, smart Commission calculation is enabled based on data from the network. The network independently regulates the most profitable Commission for the sender.

New digital currencies

The TkeySpace wallet supports +59 cryptocurrencies and tokens.

Cryptocurrencies

Tkeycoin (TKEY), Bitcoin (BTC), Litecoin (LTC), Ethereum (ETH), Bitcoin Cash (BCH), DASH, Binance (BNB), EOS.

Exchange of cryptocurrency

The “Limitless Crypto Exchange” tab is available for a quick transition to an unlimited exchange in 200 digital currencies — 10,000 currency pairs.

How do I update TkeySpace to version 1.3.0?

  1. Go to Google Play on your device — My apps and games — find TkeySpace in the list of apps — click Update.
  2. Go to Google Play on your device-write TkeySpace in the search — click on the app icon — Update.
After the update, you will need to restore your wallet.

Will there be another 2017-like crypto pump ever gonna happen again? My rant on the future of crypto, ICOs, and 2018

Background
I've been getting several messages lately inquiring about my old post from which I borrowed $30k to buy ETH back in May: https://np.reddit.com/ethtradecomments/68oshw/just_borrowed_30k_to_buy_eth_stay_tuned_for_the/
I started typing a long response to someone who asked me whether he thinks there's gonna be another opportunity like ETH in the future (from which I made over 100X returns, buying most between $10 and $100, and cashing out 90% at $1000-$1200)...and I realized I typed so much info that it could be worthwhile to share it with the community.
Before I start my rant though... about the loan I had taken out at the time: don't ever invest in more than you're willing to lose.
Opportunities will always come, in one way or another. Today is crypto, yesterday was flipping houses, before that was penny and internet stocks. But from a crypto standpoint, opportunities in this field are gonna be more rare. Bitcoin, ETH, and other large caps coins are probably done for for a while -- they'll go up in the long run but I don't think we'll see another new parabolic rise of 1000+% gains for a long while. People switched to ICOs after seeing some of the 3-10X gains, but the wild west of unregulated ICOs is starting to lose steam, mostly due to regulatory barriers.
Identifying Fundamental Disruptions
I invested in ETH first at $10 and buying all the way up to $100 (the $30k loan got me ETH at $80 each), and while others were selling for 2x flips, I was able to hold it all the way to $1000+. I think this is important to mention in the context of this post because of the necessity to realize the long-term disruption that lays ahead. At the time, I realized that ETH was about to give altcoins/tokens the ability to be speculated on due to their direct utility association in a tech startup's main business mechanism. I firmly believed that ETH should be worth at nearly as much as, if not at least, BTC in market cap because of this. Prior to ETH, it was just Bitcoins and then all clones/shitcoins. ETH gave rise to ICOs and speculative coins that could be assigned potential business value to it, thereby making crypto markets what it is today. Frankly, the entire crypto market owes ETH, and respectfully BTC of course, for what is today. Note though: I rolled the dice big for ETH, but even my $30k investment at the time was only about a quarter of my savings at the time. So again, don't invest in more than you are willing to lose or sleep soundly at night.
The Future: Increasing Regulation
Anyway, turning to the future. Here's what I think is going to happen. SEC is going shutdown alot of ICOs; they are really cracking down on ICOs claiming to be utilities, even if disguised through airdrops or SAFTs. In fact, just today's WSJ news said SEC issued subpoenas to multiple ICOs and have taken interest in SAFTs for so-called utility tokens. Just like the dot-com bubble, 90%+ of these previous ICOs are gonna tank and fail. We're gonna see a massive correction probably later in 2018, when roadmaps with major expected milestones start missing their deadlines, and a domino effect happens when SEC starts really flexing their muscle and forcing exchanges to go into delisting mode (we already are starting to see this with Bittrex).
But a Hidden Opportunity
So about looking for another crypto pump opportunity.... When the culling happens, the survivors are gonna be as follows. Look for US-based ICOs that have been SEC-compliant from the outset, or at least making a strong effort to do so. Having a legal advisor or team member will be big this year. Don't be afraid of lockups or holding periods if it's for the purpose of being SEC compliant (signs are mentions of Reg CF, Reg D, Reg S, and Reg A+ offerings... you could google these keywords with their company name to see if they have a filing record in SEC's database). See if these ICOs and team leaders had a successful and profitable business in the past, or at least spun out of a profitable company. Also, there's way too much bullshit with partnerships, many which are fake or with useless no/name companies. Next, a lot of these open ecosystem platforms rely on partner companies to attract customers -- but why would companies join when there are no customers, and vice versa. It's all bullshit and often pump and dump shilling. What you want is a closed ecosystem (think Apple iOS) to help consumers navigate the business model. An open ecosystem where customers have to attach their own crypto wallet, blah blah blah, yay decentralization, yeah... well that's all never gonna see mass adoption (think Linux... some hardcore advocates exist, but what layperson actually wants to operate command lines or deep menus all day long and accidentally break their system with one wrong syntax). Look how successful Coinbase has become by simplifying crap. Too much shit is focused on the crypto side and it's like a foreign language to mainstream customers who won't touch it with a ten foot pole. Look for ICOs that are consumer focused rather just have solely an ICO page. It's particularly appealing if they have a self-directing strategy in the form of a tangible product they can sell to generate data or transactions in their ecosystem, which would naturally attract additional customers/companies into their platform.
Examples:
These companies with revolutionary ideas, who are making an effort to be legally compliant and also have a tangible product, are the ones that are gonna survive the mass culling of alts and ICOs later this year. If we ever get our first ICO unicorn (from revenue, not pumped market cap of their token), then it will bring truly mainstream recognition of the crypto markets that will give the traditional stock markets a serious run for their money. I'm not talking about less than 1% of the $70 trillion stock market value of the world -- I'm talking like double digit levels of the entire global stock market. And I bet you it will happen. This is the sorting-out phase of the future -- a shift from old world Wall Street-type money to Silicon Valley. Crypto allows direct investments into technology startups, and tokenization of the actual business transaction mechanism cuts down all the traditional valuation crap dealing with public relations and whatever meta valuation factors. If the business is making sales, then the token is worth something, and that's all that matters. If the business is losing sales, then the token is worth less. Straightforward.
When All The Puzzle Pieces Fit Together
Two more things to note. First: If ETH successfully pulls off scaling through sharding/raiden and drastically reduces gas fees through proof of stake, then it will be fit for enterprise use. ETH's stress tested blockchain with upgrades will facilitate real world adoption (Most of these ERC20 platforms are currently not fit for real adoption due to high gas fees and low TPS). Otherwise, consider hedging into alternative smart contract-, high volume-, low cost-capable platforms with implementation documentation (e.g., Stellar) to potentially get some good gains. Second: A lot of these current crypto exchanges are not registered ATS's (alternative trading systems) that are permitted to trade securities by the SEC, so they can only trade utilities. But SEC is cracking down on these fake-utilities and are deeming them all securities... that's gonna leave these exchanges in the dust. So we're seeing big companies entering this space, Overstock building tZero, Circle/Goldman Sachs acquiring Polo, Cobinhood, etc. They are prepping for ATS compliance, and when legal tokenized securities become tradeable, they will be traded on these platforms... not hot messes like Binance. And they will be user friendly -- gateways for mainstream to invest directly in the tokenized assets of a company's core business model. It's all culminating to the survival of legit companies, mainstream adoption, and these are your clues. Enjoy trading shitcoins while they last, but don't get caught with your pants down bagholding them.
Rant over.
TL;DR Look for coins based on fundamentals and legal compliance so they will survive the massive culling in late 2018 when roadmaps don't meet milestone deadlines
Edit: Grammar, and Readability

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

If you’re interested in the details, NavCoin was initially forked from Bitcoin in 2014. And while it offers all the benefits of Bitcoin, it has been greatly enhanced such as faster and cheaper transactions. SegWit has already been voted on and activated by the community. This enables further advances in development; such as the current development of the Lightning Network (aka instant transactions). You can also choose to send optional anonymous/private payments via NavCoin’s flagship NavTech private payment technology.
This next generation blockchain also provides a Proof of Stake (PoS) algorithm to secure the network. To learn more about how PoS is more beneficial than Proof of Work (PoW) and to how you can earn 5% annually, please read the section on Proof of Stake below!

Who are contributors of NavCoin?

NavCoin is made up by contributers from all around the world - helping with the development of the core project, creating websites, and writing articles explaining how it all works. Nobody owns or controls NavCoin which means that everyone can take part.

NavCoin Proof of Stake; Earn 5%p.a.

NavCoin uses a Proof of Stake (POS) algorithm to secure the network. This has many added benefits versus Bitcoin’s use of Proof of Work (POW) to mine and confirm blocks and transactions. The benefit of using POS is that it is lightweight, requires extremely low energy consumption, and you don't need huge servers or farms to mine NavCoin. All you need is to install a Core Wallet, turn on staking mode, and you will earn 5%p.a. on the amount in your wallet. It’s that simple!

Community Fund

With the Community Fund in the final stages of development, get your community fund ideas ready! Anyone and everyone on the network will be able to propose projects, budgets and initiate network votes to schedule funds, through their staking rewards.

[uncensored-r/CryptoCurrency] Will there be another 2017-like crypto pump ever gonna happen again? My rant on the future of cry...

The following post by slickguy is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ CryptoCurrency/comments/812fmy
The original post's content was as follows:
Background
I've been getting several messages lately inquiring about my old post from which I borrowed $30k to buy ETH back in May: https://np.reddit.com/ethtradecomments/68oshw/just_borrowed_30k_to_buy_eth_stay_tuned_for_the/
I started typing a long response to someone who asked me whether he thinks there's gonna be another opportunity like ETH in the future (from which I made over 100X returns, buying most between $10 and $100, and cashing out 90% at $1000-$1200)...and I realized I typed so much info that it could be worthwhile to share it with the community.
Before I start my rant though... about the loan I had taken out at the time: don't ever invest in more than you're willing to lose.
Opportunities will always come, in one way or another. Today is crypto, yesterday was flipping houses, before that was penny and internet stocks. But from a crypto standpoint, opportunities in this field are gonna be more rare. Bitcoin, ETH, and other large caps coins are probably done for for a while -- they'll go up in the long run but I don't think we'll see another new parabolic rise of 1000+% gains for a long while. People switched to ICOs after seeing some of the 3-10X gains, but the wild west of unregulated ICOs is starting to lose steam, mostly due to regulatory barriers.
Identifying Fundamental Disruptions
I invested in ETH first at $10 and buying all the way up to $100 (the $30k loan got me ETH at $80 each), and while others were selling for 2x flips, I was able to hold it all the way to $1000+. I think this is important to mention in the context of this post because of the necessity to realize the long-term disruption that lays ahead. At the time, I realized that ETH was about to give altcoins/tokens the ability to be speculated on due to their direct utility association in a tech startup's main business mechanism. I firmly believed that ETH should be worth at nearly as much as, if not at least, BTC in market cap because of this. Prior to ETH, it was just Bitcoins and then all clones/shitcoins. ETH gave rise to ICOs and speculative coins that could be assigned potential business value to it, thereby making crypto markets what it is today. Frankly, the entire crypto market owes ETH, and respectfully BTC of course, for what is today. Note though: I rolled the dice big for ETH, but even my $30k investment at the time was only about a quarter of my savings at the time. So again, don't invest in more than you are willing to lose or sleep soundly at night.
The Future: Increasing Regulation
Anyway, turning to the future. Here's what I think is going to happen. SEC is going shutdown alot of ICOs; they are really cracking down on ICOs claiming to be utilities, even if disguised through airdrops or SAFTs. In fact, just today's WSJ news said SEC issued subpoenas to multiple ICOs and have taken interest in SAFTs for so-called utility tokens. Just like the dot-com bubble, 90%+ of these previous ICOs are gonna tank and fail. We're gonna see a massive correction probably later in 2018, when roadmaps with major expected milestones start missing their deadlines, and a domino effect happens when SEC starts really flexing their muscle and forcing exchanges to go into delisting mode (we already are starting to see this with Bittrex).
But a Hidden Opportunity
So about looking for another crypto pump opportunity.... When the culling happens, the survivors are gonna be as follows. Look for US-based ICOs that have been SEC-compliant from the outset, or at least making a strong effort to do so. Having a legal advisor or team member will be big this year. Don't be afraid of lockups or holding periods if it's for the purpose of being SEC compliant (signs are mentions of Reg CF, Reg D, Reg S, and Reg A+ offerings... you could google these keywords with their company name to see if they have a filing record in SEC's database). See if these ICOs and team leaders had a successful and profitable business in the past, or at least spun out of a profitable company. Also, there's way too much bullshit with partnerships, many which are fake or with useless no/name companies. Next, a lot of these open ecosystem platforms rely on partner companies to attract customers -- but why would companies join when there are no customers, and vice versa. It's all bullshit and often pump and dump shilling. What you want is a closed ecosystem (think Apple iOS) to help consumers navigate the business model. An open ecosystem where customers have to attach their own crypto wallet, blah blah blah, yay decentralization, yeah... well that's all never gonna see mass adoption (think Linux... some hardcore advocates exist, but what layperson actually wants to operate command lines or deep menus all day long and accidentally break their system with one wrong syntax). Look how successful Coinbase has become by simplifying crap. Too much shit is focused on the crypto side and it's like a foreign language to mainstream customers who won't touch it with a ten foot pole. Look for ICOs that are consumer focused rather just have solely an ICO page. It's particularly appealing if they have a self-directing strategy in the form of a tangible product they can sell to generate data or transactions in their ecosystem, which would naturally attract additional customers/companies into their platform.
Examples:
  • https://www.epigencare.com/ico - Selling a 23andMe-like skincare test to generate skincare profiles, then seeing how product ingredients affect the profiles. Then skincare companies can target their products to customer profiles through their recommendation engine, and present them as personalized solutions in the customer's test report.
  • https://holo.host/ico/ - Creating a new blockchain 3.0 that allows you store full websites and databases directly on the blockchain (instead of just transaction data), in order to allow decentralized hosting via peer-to-peer internet. They're selling small server boxes or software so you get paid crypto for cloud hosting (and apps and sites needing hosting pay the hosts).
These companies with revolutionary ideas, who are making an effort to be legally compliant and also have a tangible product, are the ones that are gonna survive the mass culling of alts and ICOs later this year. If we ever get our first ICO unicorn (from revenue, not pumped market cap of their token), then it will bring truly mainstream recognition of the crypto markets that will give the traditional stock markets a serious run for their money. I'm not talking about less than 1% of the $70 trillion stock market value of the world -- I'm talking like double digit levels of the entire global stock market. And I bet you it will happen. This is the sorting-out phase of the future -- a shift from old world Wall Street-type money to Silicon Valley. Crypto allows direct investments into technology startups, and tokenization of the actual business transaction mechanism cuts down all the traditional valuation crap dealing with public relations and whatever meta valuation factors. If the business is making sales, then the token is worth something, and that's all that matters. If the business is losing sales, then the token is worth less. Straightforward.
When All The Puzzle Pieces Fit Together
Two more things to note. First: If ETH successfully pulls off scaling through sharding/raiden and drastically reduces gas fees through proof of stake, then it will be fit for enterprise use. ETH's stress tested blockchain with upgrades will facilitate real world adoption (Most of these ERC20 platforms are currently not fit for real adoption due to high gas fees and low TPS). Otherwise, consider hedging into alternative smart contract-, high volume-, low cost-capable platforms with implementation documentation (e.g., Stellar) to potentially get some good gains. Second: A lot of these current crypto exchanges are not registered ATS's (alternative trading systems) that are permitted to trade securities by the SEC, so they can only trade utilities. But SEC is cracking down on these fake-utilities and are deeming them all securities... that's gonna leave these exchanges in the dust. So we're seeing big companies entering this space, Overstock building tZero, Circle/Goldman Sachs acquiring Polo, Cobinhood, etc. They are prepping for ATS compliance, and when legal tokenized securities become tradeable, they will be traded on these platforms... not hot messes like Binance. And they will be user friendly -- gateways for mainstream to invest directly in the tokenized assets of a company's core business model. It's all culminating to the survival of legit companies, mainstream adoption, and these are your clues. Enjoy trading shitcoins while they last, but don't get caught with your pants down bagholding them.
Rant over.
TL;DR Look for coins based on fundamentals and legal compliance so they will survive the massive culling in late 2018 when roadmaps don't meet milestone deadlines
Edit: Grammar, and Readability

From Ge You-esque Slouching to Blockchain Decentralization

These days, all my friends are very anxious. I heard that they stay up till 3am working on the blockchain, sending ICOs, talking about things like “if it rises or falls within the range of 50%, it’s called a stable sideways move”, and “the profit rate will at least be 100 times”. They also talk about the next-generation Internet, the greatest technology revolution since the Industrial Revolution. So, how does this decentralized blockchain influence our life?
Before we talk about the challenge of decentralization, we have to figure out why the challenge of decentralization exists.
Things after a long period of division, tend to unite; after a long period of union, tend to divide.
It is believed in China that “domains under heaven, after a long period of division, tend to unite; after a long period of union, tend to divide.” This rule applies not only to history, but also to the development of the Internet industry.
In the past, the Internet was only used to make phone calls and was monopolized by one or two large companies. This was because of the circuit switching technology back then. If we look back to even earlier age, we’ll find that people had to use manual wiring. Such low level of technology determines that the network at that time can only be centralized.
But the improvement of technology always leads to the new round of decentralization. The invention of the TCP/IP protocol gave an impetus to the arrival of the Internet era. As packet switching took the place of circuit switching, information could get around freely. Under such circumstances, it was simply impossible for one single company to monopolize the the resources of the entire network. It brought us the era of decentralization. Many portal sites and personal blogs came into being, and everyday there were newborn projects plunging into the great tide of the times.
This state of decentralization lasted for a while, then new problems appeared — information was difficult to search
Driven by this demand, search engines and super APPs became the new centers of the whole system. However, based on the data and portals that they had, these apps could collect more data. This is how centralization got to the era of cloud computing and big data.
Just as the time when TCP/IP made the world decentralized. Today, the new technology of blockchain has once again led the world to an era when centralization gives its way to decentralization.
Blockchain, Value Network and Consensus
Many years ago, I had thought, “Why can’t I just put my money into a file folder, in which each file represents a certain value, and when I send someone else a file, I simply transfer my money to him?” It is a pity that this idea could not be achieved by traditional Internet. The traditional Internet is a net of information and can only transmit the copies of those information. However, value, is not easy to transmit. But the birth of blockchain has totally changed the game and made it possible for value to be transferred, just as information is transmitted. This is the magic and charm of blockchain.
Transactions on the blockchain can only be generated by the user’s private key, and once they are recorded by the blockchain, they are impossibly to be changed. Based on the consensus of certain mathematical principles, people can trade with everyone without trusting them. Where there is consensus, there is possibility of cooperation.
All the wars and tragedies in human history are nothing but the result of the failed consensus. After the financial tsunami in 2008, almost at the same time, two people thought of a solution to all trust problems in the world.
l A Chinese and a Japanese
l Ge You and his invention, the conflict resolution terminal
l Satoshi Nakamoto and his invention, blockchain
I have explained to others what blockchain is for a million times —
  1. It’s a distributive ledger.
  2. It’s a decentralized application.
  3. It’s a consensus platform.
  4. It’s cryptocurrency
  5. It’s token economy.
I was totally enjoying my explanation, and the listeners were always like “What on earth are you talking about? Can you stop speaking Greek?”
Let’s watch an interesting video first. it’s called “Ge You and his conflict resolution terminal”. After that I’ll explain what blockchain actually is.
URL: https://v.qq.com/x/page/e133670fxux.html
Ge You is a famous Chinese comedian actor, and I mention him here just for fun. In this movie, his conflict resolution terminal only has two nodes, and simply by this, he defrauds another man to bankruptcy. We can just give it a laugh.
We can understand blockchain in this way: it is a conflict resolution terminal that countless people can participate at the same time. It can seal all the transaction contracts collectively, and no sealed participants can withdraw their transactions. One particular feature about the seal is that it’s a very complex paging seal, so that no one can change the data in it.
Using his knowledge in cryptography and POW algorithm, Nakamoto really implemented such a conflict resolution terminal. The world’s top scientists and mathematicians have verified the solidity of this theory, and after nearly ten years of running tests, nothing wrong has ever happened. And its value has increased by millions of times.
Well, I also admire Mr.Ge and his efforts for world peace.
The challenge brought by decentralization
OK I’ll skip the chitchat and go back today’s theme, the challenge of decentralization.
The challenge of technology development
Change is the only constant in life. Technology is updated and renewed everyday, and so is the technology of decentralization.
Because of its trustworthiness by nature, many systems that requires an intermediary to increase credibility are strongly impacted, such as banks, insurance industry, and lottery industry. Beside that, due to decentralization and anonymity, decentralization will impact existing industry rules in many gray dark-web trades or in the field where the law is lagging.
From the perspective of security, any problems caused by the high centralization can have great social consequences.These days, Facebook is facing a 2-trillion-dollar fine for its data breach, which is a wake-up call for everyone. As for China, let’s just imagine how our life will be impacted if Tencent or Alibaba or any other Internet industry giants go wrong.
With the commercialization of 5G technology and the explosive growth of IOT devices, the Internet traffic has shown an exponential increase. The asynchronous growth of the terminal devices and the server is a bottleneck that all centralized processing systems will eventually face.
The challenge of awareness.
We can catch up when our technology is left behind, but we will forever be stuck in the past if our mind is left behind.
Many of us have a belief that the society in which we are living, was, should be, and always will be what it is now. It’s not true.
The money you are using is not actually your own money.
The money we use today has not always been the same. In fact, it is only a few decades old. Before the Bretton Woods system collapsed, it required equivalent value of gold as the credit guarantee to issue currency. And nowadays, we always see news like the following:
1)The U.S. national debt has exceeded 20 trillion U.S dollars. 2)Xiong’an New Area received 100 billion yuan of credit. 3)China Merchants Bank grants 4 billion yuan of credit to Anbang Insurance Group
4)Anbang Insurance Group granted 10 billion yuan of credit to Guangyuan
If you can understand that national debt and credit are the same as direct currency printing, you can understand that the money you use is actually not your own money.
Blockchain is a bubble. So is the very essence of currency itself.
The reason why the release of TOKEN is so popular is that people for the first time actually realize that the essence of currency is credit. Credit, however can be created by media packaging and celebrity platform. And TOKEN is human’s first try to issue currency by blockchain. In the past, it took real guts to do such things. People who can understand it, will be zealous for it. People who don’t, call it fraud.
Companies, have not always been like their current form. Actually, in the future, they might even disappear.
Economic rules tell us that the transaction cost is the reason why company exists. A company will eventually grow to a state in which the company’s transaction costs and management costs are in balance. After that, the expansion of the company will lead to the increase in management costs. However, in the future blockchain world, the transaction of costs will inevitably converge to zero. Can companies still find their reasons to exist at that time? It’s not a long time since the first company came into being. So I would like to say that, the demise of the form of companies will not be far in the future.
In terms of market value, bitcoin market value is over $190 billion, exceeding Goldman Sachs and Morgan Stanley, as well as Boeing.
In terms of trading volume, some bitcoin companies such as Binance, OKEX and Huobi have almost reached the scale of the China A shares.
And here comes DAO, Distributed Autonomous Organization. In the future, more and more companies will be community-oriented on the base of blockchain. Also, there will be more start-up companies choosing to finance by blockchain and operate as a community directly.
Different people will have different feelings and understandings even when watching the same TV series. I watched a Chinese TV series called “Nothing Gold Can Stay”. It led me to think that, in the era of emerging capitalism, how greatly the traditional family business was impacted by the new production relations of the companies. The protagonist Zhou Ying, richest women in her province, failed not because she did not do well, but because the backward production methods dragged her down to the inevitable tragedy. Similarly, in the future, it’s not because that you are not good enough, nor your company is not good enough, but because more and more companies change their patterns and choose a decentralized and community-based mode.
Challenge of the society
The law always lags. Code is the (new) law.
The laws in almost in every country stipulate that users’ data on the Internet only belongs to the users themselves. Companies like Huawei and WeChat also claim that the data belongs to the users. But they know clearly that the data belongs to whoever has access to it.
Facebook, as well, claims that they will protect the user’s data. However, things turns out that they sell the data to whoever pay them.
All software has user authorization and agreement terms, but who will actually read it? What’s the point of reading? Since the law is merely a useless ceremony thing.
There are hundreds of laws about company governance and financing, but how does it do with decentralized communities?
The law stipulates that whoever commits a fraud over a certain amount of money will be put into jail. But in reality, there are people who just defraud billions of dollars by using the blockchain, and the law can do nothing about it.
The country is also a form of relation of production
Chinese students have learned about the relations of production since primary school. I’m not very good at it, so I won’t dig too deep.
Today, we are living in a centralized society, working in a centralized company, getting paid with the temporary coinage issued by the centralized system and imagining the challenges that decentralization will bring to our lives. Of course, our biggest goal is to make a better and fairer society by blockchain, where everyone will have more new opportunities.
In the end, I’d like to end up my speaking with a song. It’s called “ Song of Blockchain”. Hope you enjoy it.

New to NavCoin? Read here!

Welcome to the NavCoin subreddit!

What is NavCoin?
NavCoin is a cryptocurrency based off Bitcoin. While it offers all the benefits of Bitcoin, it also has added benefits such as faster and cheaper transactions, the ability to earn 5% on your NAV and optional private payments.
A key difference is that NavCoin uses the Proof of Stake algorithm to secure the network (as opposed to Proof of Work that Bitcoin and others use). The benefit of using Proof of Stake is that it's much more lightweight and you don't need huge servers or farms to mine NavCoin. All you need is to install a Core Wallet, turn on staking mode and you will earn 5% on the amount in your wallet.
What sets us apart?
How do I buy NavCoin?
The cheapest way to get NAV is through an exchange.
  1. Buy Bitcoin or Ethereum - for example using LocalBitcoins
  2. Join an exchange such as Poloniex, Bittrex or Binance and transfer your Bitcoins to your account. Some exchanges require verification for trading or withdrawing.
  3. Once there find a NavCoin trading pair (such as BTC-NAV or ETH-NAV) and make a transaction. You set the price you want to pay and how much you want and wait until someone matches that offer.
  4. You now have your NAV! The next step is to send this to your wallet and start staking. Tutorials for setting up a wallet are available here.
Where can I get more information about the project?
