Aztec launches private smart contracts as Ethereum rollup

Aztec, a privacy protocol developing on Ethereum, announced on Monday the launch of its second iteration, promising private transactions and smart contracts while being cheaper than standard transfers. Loopring focuses on the decentralized exchange experience, while ZkSync aims to be a generalized layer two protocol that could boost Ethereum’s transaction throughput.

The team says that the rollup can reach 300 transactions per second while allowing shielded ERC-20 token transactions and private interactions with decentralized finance protocols. The stated throughput is a far cry from potential figures on other zkRollup solutions, but it is still well above Ethereum’s maximum theoretical throughput of 40 transactions per second.
