Backup Wallet.dat

"1) I can backup my wallet by exporting a wallet.dat file. Do I have to do this everytime I receive more BBP? Or just whenever I add a new key? 2) How do I add new keys? 3) Can I generate and see the private key so that I can write it down/print it and store it somewhere safe?" -znffal
1) think of your wallet.dat file as your passbook in a passbook savings account. You have to have that .dat file to be able to access (and prove you SHOULD have access) to the BBP stored in your account addresses. Exporting it once is all you need.
2) Adding new keys? The passphrase (password) you use is the only "key" you would have in an encrypted wallet (besides the .dat file). If you mean new addresses, you can get those by going under File and Sending (or Receving) Addresses and hit "new".
3) Clicking Encrypt Wallet will be where you choose a passphase, I don't know you can see it other than when you enter it.
To put a real world example or two.
Example One: You don't ever encrypt or backup your wallet. If I borrowed/stole/hacked your computer, I could send all your coins to my wallet (no passphrase).
Example Two: You encrypt your wallet with the passphrase "secret" but don't backup the wallet.dat file, then your computer crashes and you lose all your data. Since you didn't have a copy of the wallet.dat file, your coins would be lost.
Example Three: You backup your wallet.dat but don't encrypt it. Your computer crashes and all your data is lost, but you re-download the QT program, restore your wallet.dat, all your coins are still in you wallet. But if you lose your USB drive that has the wallet.dat on it, and I find it, I can put your wallet.dat on another computer and send all your coins to my wallet.
Example Four: You encrypt your wallet and back up the wallet.dat file. If I hack/borrow your computer, unless I guess your passphrase your coins are safe. If you computer crashes, your can restore your wallet.dat file to another computer and your coins are safe.
In short, Encrypt your wallet (passpharse) and then backup (copy) the wallet.dat file to at least two locations." -616westwarmoth
"Find your wallet.dat file, copy it to a flash drive or any other secure place. If your computer crashes, you'll always have the wallet.dat and can put it on a new machine. It will have to resync a bit when you do, but you'll never lose your "key" to the wallet. Speaking of keys, you should password protect your wallet and make sure to remember it!"
"Yes you must have a copy of the wallet.dat somewhere. So multiple back up copies are a good idea. If you lose the wallet.dat file the coins will be in limbo but there will be no way to recreate the file. One thing to remember is it doesn't matter if the wallet.dat file is "current", it can be 10 years old on a flash drive and you can download a new client, put the wallet.dat file into the machine and you'll be good." -616westwarmoth
"In addition to this, whenever you reboot the node after more than 24 hours of being synced, we back your wallet.dat up into the "backups" folder. This is useful if you ever accidentally delete your wallet.dat.
Also, if you want a paper backup, you can do a 'dumpprivkey accountaddress' command from the RPC." -Rob
"wallet is a collection of private keys"
"there are other ways to achieve high security. You can make a new wallet, encrypt it with a long password, send coins to it, put it on a flash drive and put it in cold storage, then download the hard drive cleaning program and erase the wallet.dat sectors from your PC. And of course, keep a printed copy of the private key on paper and put it in a safe. Put the usb in the safe also. Burn a cd rom with the wallet.dat file and put it in the safe." -Rob

NOTE: As of version 1.4.3.1 we have updated to HD wallets, so you should not need to worry about keypools anymore if you have upgraded
"Regarding the Sanctuary, you receive payments always to the same address (key), so the keypool is not consumed for those payments. But when you click to generate a new address on the "Receive" tab, one key will be deducted from the keypool. Also, sometimes new addresses are automatically generated and the keypool is consumed, for example when solo mining and finding a block, a new address could be used for the block reward.
You can always check your current keypool size by typing "getwalletinfo" in the RPC console and see "keypoolsize" and "keys_left". It's only concerning if they are a low number and you plan to generate new addresses in your wallet. They start from 1000. If the number gets too low, you can just type "keypoolrefill" to refill them back to 1000 and then you should backup the wallet. But from my experience the wallet automatically refills the keypool from time to time (or after certain actions like transactions), because I see that my wallet file keeps getting larger and the "keys_left" returns to 1000.
The only issue is if you actively use your wallet on multiple computers (for example cloud mining or simply sometimes using the wallet on your laptop), then one wallet could refill the keypool with new addresses and the other one will not, or they will generate different new addresses. If I understand this correctly, for example, you could receive a payment on a new address generated in one wallet; your old balance will be there on both wallets, but only the one wallet where you generated the new address would show the new payment. Then you should copy the wallet.dat file to other computers, to update them.
If you use the wallet on just one computer, you should just backup the wallet from time to time (or when you see it has increased in size). Qt also backups wallet.dat automatically, those can be found in the folder %AppData%\BiblepayCore\backups, you will see that they also have timestamps in their names and possibly different sizes." -inblue

[uncensored-r/CryptoCurrency] Why you should be voting to support Elastos on the Binance Community Vote

The following post by Blazarius120 is being replicated because the post has been silently removed and some comments within it have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ CryptoCurrency/comments/7zsfgh
The original post's content was as follows:
Elastos project needs your help. Partnership with NEO and Bitmain. 17 years in development. 4 million lines of code.
For the sake of the market, vote for it on the Binance community vote, it has the potential to activate a market bull run. Check the 24 hour volume and its trading on 1 exchange.
Upvote please for transparency.
What is Elastos?
Elastos is the world’s first internet operating system that uses the internet as the base-layer infrastructure rather than an application. Elastos prohibits application programs from directly accessing the network in order to eliminate most viruses and attacks(especially DDoS attacks) on the internet. According to Elastos, network communication should be separated from application computing. Elastos is building a truly decentralized Smart Web powered by blockchain implementing P2P economic infrastructure while also providing digital asset ownership and management through smart contracts.
Brief Summary?
Bitcoin = Trustworthy Ledger
Ethereum = Trustworthy Ledger + Smart Contracts
Elastos = Trustworthy Ledger + Smart Contracts + Monetizable Dapps and Digital Assets
Development History(Tens of Millions of Open-Source Code spanning Decades)
In 2000, Rong Chen a Tsinghua alumni left Microsoft and returned to China to start his business.
In 2003, Rong Chen was received by Jin-Tao Hu, the former CPC General Secretary.
In 2013, Foxconn funded Elastos with 200 million RMB.
In 2017, Sunny Feng Han and Ji-Han Wu started running the Bitcoin Investment Elastos Blockchain Community and founded G3 with Bitmain and NEO.
In 2017, the Elastos Blockchain community received a global digital token investment worth 600 million RMB.
What is the Elastos Blockchain structure?
Elastos blockchain works as a trust zone for the entire network operating system that applies main and sidechain solutions to facilitate the smart economy and a healthy decentralized application environment. This means that every application built on Elastos can create individual sidechains that is thoroughly customizable, allowing clients to pick a different consensus method depending on the use case. The structure of main chain and side chain avoids main chain being overloaded and leads to easy routing and flexible extension, increasing the possibility for Elastos to be largely scalable.
Elastos implements merged mining with bitcoin. This strategy saves resources and avoids repeated consumption. Miner submits Proof-of-Work(PoW) to both bitcoin and elastos and enjoys profits of mining competition without extra consumption of computing power. The consensus mechanism for Elastos is AuxPoW+DPoS where the mining reward distribution is 35% for AuxPoW, 35% for DPoS, 20% for Ecosystem Application Reward and 10% for Foundation Running and Development. Tokens for apps built on Elastos can be published on sidechains. These tokens may participate in two-way asset transfer across the main chain and side chains.
What is the business model for Elastos?
Provide large blockchain applications with secure running environment
Digital content remains intact after multiple uses
Big data and digital content can identify ownership on blockchain and correspond to tokens
Tokens can be transferred and traded legally on blockchain, realizing future capital
Usage of tokens can consume/use digital content in Elastos Runtime.
Elastos can set a fixed limited amount for digital assets, thereby creating scarcity of valued products
Example of how the above works?
Content creators create 500 copies of limited edition games built on top of Elastos
Users buy these limited copies
They then play these games in Elastos Runtime on their cell phones, desktop computers, game consoles, etc.
Holders of these limited edition games then resell them to other people. Because this game is of limited edition, it fluctuates in the second-hand market. It helps users enjoy the digital content, earn the early benefits and earn some by reselling it, thereby transferring the ownership to other people.
Ethereum v Elastos?
Ethereum: Single mainchain structure leads to the upper limit of computing power and extensibility. Elastos: Proposes to adopt a flexible main chain and sidechain blockchain design structure. The main chain is only responsible for basic transactions and payments while the sidechain executes smart contracts to support various applications and services.
Ethereum: As storage and computing space, blockchain is not able to support user daily life scenarios and not able to support digital content(eg. Cryptokitties). Elastos runs applications on elastos runtime as opposed to the already congested blockchain. This method is more secure. All network data must be sent through a trustable and verifiable channel. Identification and authentication come from the blockchain ID. This way, the blockchain’s credibility can be transferred to Elastos Runtime. Elastos Runtime can have various forms: an independent OS, a virtual machine, or a software development kit(SDK) that integrates into native apps of other mainstream operating systems.
EOS v Elastos?
EOS: Is a blockchain OS, but its development period and open source codes are much shorter than Elastos’ 17 years. Elastos has released more than 4 million lines of code to github and plans to release 10+ million lines of code in total(contributing to the open source community).
EOS is dependent on its main-chain, so no matter how optimized it becomes, its throughput is limited. Elastos can extend the throughput infinitely with flexible main-chain and side-chain solution. Also, Elastos Runtime can deliver the trust function of the blockchain to a user’s application(like a cell phone, laptop, etc) which applies the blockchain to various scenarios in daily life.
EOS, through the adoption of the DPoS consensus mechanism, can realize high throughput rate. Elastos computation bandwidth is distributed according to the number of tokens held. It refers to the design philosophy of time sliced distribution in the traditional multi-task operating system and encourages the community to hold tokens. The main-chain design focuses on improving extensibility for smooth access to sidechain. The consensus mechanism on the sidechain can be anything(from DPoS to DBFT to anything else)
EOS runs everything utilizing main chain for everything. Elastos: Services on the elastos blockchain layer can be shared by multiple side chains. This greately lowers the mainchain pressure. When necessary, the sidechain can be duplicated to extend sidechain-level service capability through bifurcation mechanism, while the extension of this computing power can be infinite
Blockstack v Elastos?
Blockstack combines encrypted, distributed storage and blockchain ID to make sure all the data belongs to the owner. As for Elastos, it applies a similar method for digital assets storage where users could apply for an ID for their digital assets on the blockchain, which guarantees the ownership of those digital contents but a key differentiation with blockstack is that the ownership of these digital contents will also be transferable and tradable, thereby making these digital assets consumable and investable and of high value, thereby contributing to a smart economy of trading digital goods. Even though the digital assets are decrypted, they cannot escape elastos runtime operating environment which guarantees that it will never disclose or damage the ownership of the digital contents.
Blockstack saves encrypted data files in the cloud and hash stamps for these files are put on the blockchain as a proof mechanism but doing this is a trade-off between high credibility, low efficiency of blockchain and low credibility, high efficiency of traditional storage. Meanwhile, Elastos has its P2P network layer called Elastos Carrier that focuses on making the elastos blockchain cluster chain service integrated into the same network as the elastos runtime thereby unifying the services with DApps so both the data and the ID of digital assets can have high credibility along with high efficiency for blockchain storage.
For the tech savy?
Elastos VM: The VM runs on a host OS and has better integration with current mainstream OS such as Android and iOS. It ensures formation of a closed runtime environment enabling the separation from the host OS, ensuring safety of data and code. The ‘Remote Service Interface’ replaces the traditional TCP/IP programming model, providing safe and reliable network transactions. This means no more IP addresses and a discovery mechanism will be used instead to access dapps and websites on the elastos internet(where each item has its own UUID - Universal Unique Identifier).
Elastos Runtime: A software library that contains some of Elastos functionality. It provides the target OS applications with the needed Elastos functions, similar to the Alipay SDK serving other applications and making them capable of having payment functions. Elastos runtime can use trusted network communications and conduct safe and reliable data exchange and allows information exchange with the blockchain, confirming digital asset ownership and identity.
Elastos Browser: A specialized browser where the Elastos runtime is embedded. In this browser, web applications can run with partial Elastos functions. Using Elastos browser bridges the gap to provide JS programming...
