A standalone wallet for Android devices which does not depend on any centralized service and gives you full control over your bitcoins.A single-page application which allows you to store bitcoins securely and transfer them easily.It is an HD wallet which means your balance and full transaction history can always be restored using a single mnemonic code should anything bad happen to your device.This wallet is intended for mobile devices, hence it does not store a full Blockchain but instead acquires all the relevant data from random Bitcoin nodes using an SPV technique.All Bitcoin addresses and private keys in Simple Bitcoin Wallet come from a single mnemonic code which is essentially a secret phrase comprising of 12 random words.Please remember: whoever knows your mnemonic code also fully controls your bitcoins so it should be kept private at all times.Also, in case if you lose your device or forget your wallet password only mnemonic code can get your bitcoins back, it's that important!

Ideally one of the following actions should be taken once a new wallet is created: Here's a simple heuristic: treat any unconfirmed incoming transaction as if it does not exist yet.There are a lot of technical reasons for this and the rule applies to all wallets, not just to Simple Bitcoin Wallet.Just wait for at least one confirmation and you'll be fine.Every transaction you send must have some fee attached to it.Fee goes not to wallet developer but to Bitcoin miners who include transactions in blocks and thus give them confirmations.The higher fee you choose the faster transaction will be confirmed.Due to privacy considerations wallet has not one but many addresses.In fact, wallet's default address gets changed on every new incoming transaction.Never worry about it as all the old wallet addresses stay valid forever and you can use any of them to receive funds.It's important to understand that Simple Bitcoin Wallet is not a centralized service so you can't regain access to your funds by just providing an email or something like that.

Here you'll need to restore a wallet using your mnemonic code and this is how to do it step by step: Erase all current wallet data if you know how to do that (such an option is typically available in System Settings), otherwise just reinstall an application from scratch.Open fresh application and you'll be given an option to restore your wallet instead of creating a new one, choose it and enter your mnemonic code as well as new wallet password.bitcoin piattaformaImportant note: restored wallet will appear empty at first and that is completely normal as it needs some time to catch up with network.bitcoin miner peruIn case if you happen to run a full Bitcoin node which accepts incoming connections you can explicitly instruct Simple Bitcoin Wallet to use it by providing your full node's IP address and port.bitcoin miner map

Oh…and don’t be a cheapy!Try this on a VPS with at least 2GB ram (full disclosure, it’s a DO referral link), or else compiling will probably fail.Also you might run into ram issues while running the daemon if you’re using less.Remember, for bitcoin you’re going to need at least 30GB just to store the blockchain.I’m sure you know this by now, but I’ll say it none the less…keep your server secure!You wallet contains valuable coins, that if compromised, you can never retrieve.First we update the operating system and install the necessary packages for building our wallet.Let’s add the Bitcoin PPA and install: Now we need to create a bitcoin user.You don’t want to be running the bitcoin daemon as root.Also we’ll change to the bitcoind user.We make the necessary directories and setup a config file.If you want to run on testnet add the following to /home/bitcoind/.bitcoin/bitcoin.conf: We’re now ready to fire up bitcoind: NOTE: It will take quite a while for the wallet to sync with the network.
