Enhanced Privacy in Silent Payments

In this episode of Bitcoin, Explained, Aaron and Sjors welcome Ruben Somsen and Josie to the show to discuss BIP 352, their now-finalized Bitcoin Improvement Proposal for Silent Payments.

As previously discussed in episode 58, Silent Payments use a special type of addresses that allow senders to generate public keys for transaction recipients, in such a way that these recipients can in turn generate the associated private keys. This benefits privacy, as Bitcoin users can freely share a static address, without this resulting in address reuse on the Bitcoin blockchain.

Aaron, Sjors, Ruben and Josie recap how this works. and discuss some of the implementation details for the BIP, including how light clients can utilize Silent Payments, how these payments are made compatible with CoinJoin, and an extra feature called “labels”.
