Zero-knowledge rollup know-how tasks have been making headlines currently.

Polygon launched its zkEVM (zero-knowledge Ethereum digital machine) know-how on the Ethereum mainnet simply three days after ZkSync Period entered the general public eye. Different tasks corresponding to Scroll, a zk-rollup know-how centered on scaling Ethereum and Starknet, are additionally gaining traction. 

All of those tasks, regardless of their difficult phrases, have the identical objective — to scale the Ethereum blockchain.

Rollup know-how is constructed on prime of an current blockchain. It’s designed to batch or bundle transactions and execute them off chain, in the end lowering the quantity of block house required to make a transaction. This implies cheaper fuel charges as mounted prices at the moment are shared between the batched person transactions.

In contrast to optimistic rollup know-how that assumes info in a transaction is correct, builders have designed zk-rollups in order that the know-how itself can decide if the data is executed precisely with out disclosing the data on the mainnet.

How are the rollups monitoring?

Zk-rollup know-how remains to be very a lot in its infancy, and iterations are nonetheless being made to the tech though it’s now publicly obtainable to customers.

Arbitrum and Optimism nonetheless maintain the vast majority of person funds, and their ecosystems boast the 2 hottest optimistic rollups. Arbitrum secures virtually 67% of the market share and Optimism secures somewhat over 20%, info on L2Beat reveals. 

Of the completely different zk-rollup applied sciences, zkSync has seen probably the most adoption, with an estimated $244 million bridged onto the layer-2. Of this, roughly $117 million has been deployed onto DeFi contracts on the layer-2, in accordance to info from DeFiLlama. 

By comparability, its opponents Starknet and Polygon’s zkEVm have seen roughly $37 million and virtually $5 million bridged, respectively. 

ZkSync Period now has 22 protocols deployed on-chain, and Polygon’s zkEVM has 10 — its newest being the decentralized trade Uniswap.

Zk-rollup know-how remains to be very new, and ongoing audits and iterations to make sure the security and safety of those layer-2s are nonetheless being made. Blockworks Analysis not too long ago revealed a analysis report providing a deep dive into the way forward for zk-rollup know-how and the way it might affect Ethereum shifting ahead.
