Zero-knowledge rollup expertise initiatives have been making headlines these days.
Polygon launched its zkEVM (zero-knowledge Ethereum digital machine) expertise on the Ethereum mainnet simply three days after ZkSync Period entered the general public eye. Different initiatives akin to Scroll, a zk-rollup expertise centered on scaling Ethereum and Starknet, are additionally gaining traction.
All of those initiatives, regardless of their difficult phrases, have the identical aim — to scale the Ethereum blockchain.
Rollup expertise is constructed on high of an current blockchain. It’s designed to batch or bundle transactions and execute them off chain, finally lowering the quantity of block house required to make a transaction. This implies cheaper gasoline charges as fastened prices at the moment are shared between the batched person transactions.
Not like optimistic rollup expertise that assumes data in a transaction is correct, builders have designed zk-rollups in order that the expertise itself can decide if the data is executed precisely with out disclosing the data on the mainnet.
How are the rollups monitoring?
Zk-rollup expertise remains to be very a lot in its infancy, and iterations are nonetheless being made to the tech though it’s now publicly out there 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 slightly over 20%, data on L2Beat reveals.
Of the completely different zk-rollup applied sciences, zkSync has seen essentially 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 line with data 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 alternate Uniswap.
Zk-rollup expertise 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 expertise and the way it might influence Ethereum transferring ahead.
