Polygon Stakes Claim to Fastest Zero-Knowledge Layer 2 With ‘Plonky2’ Launch

“We’ve had ZK-proofs for some time, but what we haven’t had is a way to prove Ethereum ( $1,885.37 ) transactions, which are complex. It wasn’t possible to build a layer 2 that supports these transactions, which might have a flash loan, an arbitrage trade, a swap, all in one transaction. Proving them wasn’t possible until now,” he said.
