Second Layer Ethereum Scaling Solution ZK Sync Launched to Rival Visa
ZK Sync will enable privacy and scalability by adopting Ethereum’s security, the scalability induced by layer two solutions, and privacy propagated by zero-knowledge rollups (ZK rollups), December 5, 2019. As a simple primer, ZK rollups work by taking a bunch of transactions, putting them in a smart contract on-chain, adding the smart contract to a rollup block, and producing a zero-knowledge proof to verify any of the transactions in the block.
Matter Labs believes with ZK Sync and its proprietary SNARK, RedShift, they will be able to scale Ethereum for Visa level throughput – approximately 2000 transactions per second (TPS), compared to Bitcoin’s 3-5 TPS and Ethereum’s current 15-20 TPS. In short, a validator posts a bond and is responsible for collecting transactions in a smart contract and deploying it, and creating the rollup block.
