Vitalik Buterin donated to Shielded Labs to support its Crosslink development

An independent core development team led by Zcash (ZEC) founder Zooko, Shielded Labs, announced that it has received a donation from Vitalik Buterin, aimed at supporting the development of Crosslink.

It is reported that Crosslink enhances Zcash's existing proof-of-work (PoW) consensus mechanism by adding a parallel finality layer, thereby preventing chain reorganization and rollback attacks. All block generation and economic activity still occur on the PoW chain, while the finality mechanism anchors blocks and provides stronger settlement guarantees. By ensuring that confirmed transactions are irreversible, Crosslink reduces the risk of double spending and increases the reliability of transaction settlements. In commenting on the donation, Vitalik stated, "Zcash is one of the most trusted cryptocurrency projects, always maintaining a focus on privacy. The Crosslink project by Shielded Labs will make Zcash more secure while reducing the security budget, thus supporting its long-term sustainability."
