Welcome to Bob Wallet

Note: This software is in Beta and should only be used on Testnet until thoroughly tested!

What is Bob Wallet?

Bob Wallet was created to help preserve Bitcoins fungibility. Today it is easy to trace Bitcoin transactions from address to address by simply using any public Block Explorer. Bob Wallet helps fix this.

To start, you will create a Bob Wallet and deposit Bitcoin to your Public address. Bob Wallet will automatically move your Bitcoin from your Public to your Private Wallet. This transfer happens by joining together all other Bob Wallet users in order to create a single transaction called a CoinJoin. Your Bitcoin can not be stolen since only you own and control your wallet keys and no one can determine your Private Wallet addresses. Let's help keep Bitcoin fungible!

What is Bob Wallet not?

Bob Wallet is not a traditional Bitcoin wallet. You cannot use it to make a payment to someone else. It's only purpose right now is to move your Bitcoins from your Public Wallet to your Private Wallet securely without anyone knowing your Private Wallet addresses. You will have to use a separate Bitcoin wallet after your Bitcoin has been moved Private in order to spend them. Ideally, use a full-node for your Private Wallet because 3rd-party balance queries can de-anonymize you.

Questions

• What is Bob Wallet?

  • Bob Wallet securely connects you with many other users to create a single transaction called a CoinJoin. Bob Wallet will create you two wallets: Public and Private. You will deposit Bitcoin to the Public Wallet and Bob Wallet will automatically send it to your Private Wallet. By joining a combined transaction with as many people as possible it ensures the privacy of your Bitcoins in your Private Wallet. Not even the server can figure out which Private Wallet address is yours.

• Why is Bob Wallet needed?

  • To help preserve Bitcoin fungibility. Every Bitcoin transaction can be easily traced and balances determined. Not everyone needs to know how much Bitcoin you own by just visiting a Block Explorer.

• How is Bob Wallet trustless?

  • It uses a combination of CoinJoin and Chaum's Blind Signatures. You never hand over control to anyone and your Bitcoin can not be stolen. You can read more about the techniques here.

• Why do I have to use Tor?

  • Tor is necessary to protect the server from determining your Private Wallet addresses. No one but you knows the addresses of your Private Wallet.

• Why do I have to wait so long for Bitcoin to show up in my Private Wallet?

  • Every successful round will deposit a specific amount of Bitcoin into your Private Wallet. For beta testing purposes the output amount is really low so that more rounds can be run while using less Testnet Bitcoin. This will be changed later.

• Why did we build Bob Wallet?

  • For your donations and to compete for this bounty. Help support us if you like Bob Wallet!

• How can I help?

  • Help by using and contributing to Bob Wallet. The more people we have using it the faster we can find and fix bugs and improve the experience. Once we are sure Bob Wallet is safe and secure we can move it to the Mainnet. Donations are also much appreciated! Let's help keep Bitcoin fungible!
