Researchers Propose Zcash-Style Privacy for Bitcoin Without a Soft Fork

Key Highlights Researchers from Alloc Init proposed “Shielded Bitcoin,” a metaprotocol that hides BTC transfer amounts and counterparties using zero-knowledge proofs without altering Bitcoin’s consensus rules or requiring trusted bridges. The design adapts Zcash’s encrypted-note model directly on Bitcoin’s base layer, allowing anyone to run indexers that verify proofs and track nullifiers to prevent double-spending. ...

Researchers Propose Zcash-Style Private Bitcoin Transfers Without Soft Fork

Key Highlights Alloc Init researchers propose Shielded Bitcoin, a metaprotocol bringing Zcash-style private transfers to Bitcoin without a soft fork, using encrypted notes and zero-knowledge proofs. The system relies on Bitcoin as a “neutral publication and ordering layer” while separate indexers verify ZK-proofs and prevent double-spending, avoiding base-layer consensus changes. Critics highlight a small initial ...
