Vitalik Buterin has donated to Shielded Labs to support development of Crosslink, a proposed consensus upgrade for Zcash. Crosslink adds a parallel finality layer on top of Zcash’s existing PoW consensus, aiming to reduce reorg and rollback risks while providing stronger settlement guarantees for confirmed transactions—lowering double-spend risk, shortening confirmation times for exchanges and cross-chain use cases, and improving support for applications that depend on deterministic finality. https://t.co/n ...
