Vitalik Buterin Donates to Enhance Zcash Security

On February 7, the independent core development team Shielded Labs, led by Zcash (ZEC) founder Zooko, announced a donation from Vitalik Buterin. According to BlockBeats, the donation aims to support the development of Crosslink. Crosslink enhances Zcash's existing proof-of-work (PoW) consensus mechanism by adding a parallel finality layer to prevent chain reorganizations and rollback attacks. While block generation and economic activities continue on the PoW chain, the finality mechanism anchors blocks and provides stronger settlement assurances. By ensuring that confirmed transactions are irreversible, Crosslink reduces the risk of double spending and improves the reliability of transaction settlements. Vitalik Buterin commented on the donation, stating, "Zcash is one of the most trusted cryptocurrency projects, consistently prioritizing privacy. Shielded Labs' Crosslink project will make Zcash more secure while reducing the security budget, thereby supporting its long-term sustainability."
