zero-knowledge proofs

Researchers have introduced a proposal called 'Shielded Bitcoin' aimed at bringing transaction privacy to Bitcoin without requiring a network-wide soft fork. Misha Komarov, co-founder of alloc/init, explains that the design uses zero-knowledge proofs and Bitcoin PIPEs to hide on-chain transactions. The proposal is drawing attention in crypto circles, where privacy upgrades to Bitcoin have long been debated given the trade-offs between confidentiality and network consensus rules.
