Zero-knowledge (ZK) roll-up tech company StarkWare founder Eli Ben-Sasson claims that its new Recursive validity proofs could theoretically scale up 60 million transactions into one on the Ethereum blockchain. StarkNet is a permissionless and decentralized layer-2 ZK-rollup that utilizes Validium to scale transactions. Similar to ZK-Rollups, Validiums work by aggregating thousands of transactions into a single transaction.
