London, September 2017. BIP175 Pay-to-Contract protocol went into draft status earlier this month and is an implementation of the work on homomorphic payment addresses and the pay-to-contract protocol by Ijah Gerhardt and Timo Hanke in 2012. The new BIP can potentially open up Bitcoin to use cases not previously achievable on the public Bitcoin blockchain.
The protocol is designed to mimic real-world payment interactions between merchants and customers whilst ensuring only the merchant and customer have cryptographic proof of who is being paid and for what. This has been achieved via a multiparty key derivation scheme by extending BIP-0032 (Hierarchical Deterministic Wallets).
“We believe that BIP175 is one of the first building blocks to truly decentralise finance“ Nicholas Gregory, CommerceBlock
