Vitalik Buterin says ZK-Rollups will be Ethereum’s main Layer-2 solution

In the long term, ZK-Rollups-based L2 scaling solutions will surpass Optimistic Rollups. This forecast was given by Ethereum co-founder Vitalik Buterin, The Block reports.

At the ETHSeoul conference, Buterin noted that while Optimistic Rollups is a more mature technology thanks to the speed of deposits and withdrawals into the mainnet, ZK-Rollups will edge out the competitor.

“You won’t have to wait seven days to transfer assets. I expect that in about ten years all Rollups will be primarily based on cryptographic proofs,” he said.

The Ethereum co-founder acknowledged the shortcomings of ZK-Rollups and the difficulties in their development. There are many challenges, especially in securely executing processes and in verifying the correctness of all algorithms, he added.

In December, Buterin placed ZK-Rollups at the center of Ethereum’s probable roadmap for development.

Earlier, the Matter Labs team announced the launch of zkSync 2.0 on the Ethereum mainnet for a limited group of users. zkSync is an EVM-compatible EVM-based Layer-2 solution built on a zero-knowledge proof protocol.
