Shielded Bitcoin proposal could add private transfers without a soft fork
Bitcoin could get private transfers without changing its base-layer consensus rules. The Shielded Bitcoin proposal uses zero-knowledge proofs, the same broad style of cryptography associated with Zcash, to hide senders, recipients, and transaction amounts without a soft fork.
Alloc Init researchers describe a system where BTC moves into encrypted notes, transfers happen inside a shielded pool, and withdrawals break the visible on-chain link. The pool is designed to operate without a company running it.
