Researchers have proposed a way to make Bitcoin private without changing Bitcoin itself. Misha Komarov, co-founder of alloc/init, explains Shielded Bitcoin: zero-knowledge proofs that hide the sender, receiver, and amount of a Bitcoin transfer, with no soft fork, no custodians, and no bridges. He covers how Bitcoin PIPEs make it possible and what the proposal still needs. It is a research proposal, not a finished product.
