Billion – Bitcoin Wallet

Fellow Bitcoin users, we are delighted to invite you to participate in an open beta of a brand new Bitcoin wallet for iOS devices – Billion! A wallet that is extremely easy to use for people who are just entering the world of Bitcoin yet works in full harmony with the network.

Gorgeous user interface and hassle-free experience

We have developed a new visual paradigm of interaction with the most advanced financial system. Everything that is important is within a reach of a finger. All complexities are hidden under the hood. Making a transaction is now no harder than sending a message with WhatsApp.

A picture is worth a thousand words

System of Social Connections

With Payment Codes (aka SPV Stealth Addresses) two people can easily establish a secure payment 'tunnel' and make transactions whenever they need. Secure means there will never be an address reuse, and no one from the outside will be able to calculate the actual addresses.

You can publish a Payment Code anywhere on the internet or offline. No prying eyes would be able to monitor your financial activity. You can establish payment tunnels with users of other wallets, meaning no walled gardens. Apart from Billion on iOS, Samurai on Android supports this feature.

Establishing a tunnel requires a special one-time on-chain transaction that costs a fee, though it's a negligible amount of satoshis for those who have longterm financial relationships or desire a special privacy.

Technologies on which Billion is based on

  • Bread SPV (Simple Payment Verification) and network engine that has been tested by thousands of users for years
  • Private key management in compliance with BIP44; storage inside a secure enclave of iPhone – the best in smartphone industry hardware encryption solution. Your iPhone is your hardware wallet. Literally.
  • BIP47 Reusable Payment Codes for Social Connections

Segwit2x statment

Due to a lightweight SPV architecture Billion is inherently vulnerable to an attack during which hostile miners produce a chain with modified protocol rules. Our vision is based on a fact that Bitcoin is anti-fragile, therefore we do not support any protocol changes that lack a consensus among majority of the participants.

Billion would be released on the App Store after the fork with hardcoded blacklisted hash of the first S2X block. That way, Billion will follow the Bitcoin chain with no regard to it's height. Users would need to make extra steps to properly split their coins between Bitcoin and S2X blockchains to protect themselves from replay attacks. Not a trivial task in case of S2X lack of replay protection yet we will provide a detailed manual prior to the fork.

Evolution Group Limited

We are self funded team of Bitcoin enthusiasts. Billion is open-source project managed by Evolution Group Limited (Hong Kong), available under the terms of MIT licence. Give us a star on GitHub!

Beta – Stage 1

Billion is in open beta development stage. You can join by sending an email request to Prerequisites: iPhone running iOS 10+.

It is just the beginning
