For most of 2022, several Ethereum [ETH] scaling solutions rose to the occasion to help out the blockchain’s lagging transaction speed. This happened without compromising its security and decentralization. And yet, it was for this reason that Optimistic roll-ups including Optimism [OP] and Arbitrum have been able to gain widespread adoption.

Zero-knowledge (ZK) rollups have been part of the scaling solutions developed to solve the inherent scalability issue. Unfortunately, this group has not been able to gain attention like its Optimistic counterparts, despite the plethora of ZK Ethereum Virtual Machines (zkEVMs)
For context, the zkEVMs help to execute smart contract transactions in a compatible way with zk proofs existing on the Ethereum infrastructure. Therefore, this leads to customizable off-chain and on-chain scaling.
Bankless, in its recent newsletter , highlighted the possibility of zkEVMs replicating the optimistic rollup 2022 performance. But, why do these projects have the potential? According to the blockchain insight platform, ZK rollups have the potential to become Ethereum’s mainstream scaling platform because it could increase the transaction speed by 6500%.
However, there are limitations if these rollups can reach their potential. The most notable is the Total Value Locked (TVL) factor. The TVL describes the amount of underlying supply secured completely by a protocol.
At press time, L2BEAT revealed that none of the ZK rollups had been able to overthrow either Arbitrum or Optimism as per this metric. The biggest ZK rollup dYdX had only a TVL of $360 million. This was far below the Optimistic leaders which run into billions of
