Vitalik Buterin backs Shielded Labs to advance Zcash crosslink upgrade
#ShieldedLabs said Vitalik Buterin has made a donation to support development of
#Crosslink , a proposed security upgrade to Zcash’s consensus design. The funding will be used to move Crosslink from a prototype toward an incentivized testnet and further production work.
Crosslink adds a finality layer alongside Zcash’s proof-of-work chain to reduce reorganization and rollback risks.
