Researchers Propose "Shielded Bitcoin" to Bring Zcash-Style Privacy to BTC
- —The 56-page paper was released on 24 September by Shikhelman, Komarov and Moskvin
- —A two-input, two-output transfer produces a 610-byte envelope including a 192-byte proof
- —The design uses Groth16 proofs and requires a trusted setup ceremony
- —Peg-in and peg-out of real bitcoin are left to a separate PIPEs v2 paper
Why it matters: If built, it would give Bitcoin optional privacy without a fork, though trusted setup and relay policy risks remain unresolved.
