Zero-knowledge rollup know-how initiatives have been making headlines recently.
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 initiatives reminiscent of Scroll, a zk-rollup know-how targeted 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 know-how is constructed on prime of an present blockchain. It’s designed to batch or bundle transactions and execute them off chain, in the end decreasing the quantity of block area required to make a transaction. This implies cheaper fuel charges as fastened prices at the moment are shared between the batched person transactions.
In contrast to optimistic rollup know-how that assumes data 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 out there to customers.
Arbitrum and Optimism nonetheless maintain nearly all of person funds, and their ecosystems boast the 2 hottest optimistic rollups. Arbitrum secures nearly 67% of the market share and Optimism secures just a little over 20%, data on L2Beat reveals.
Of the totally 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 with data from DeFiLlama.
By comparability, its opponents Starknet and Polygon’s zkEVm have seen roughly $37 million and nearly $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 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 printed a analysis report providing a deep dive into the way forward for zk-rollup know-how and the way it might impression Ethereum transferring ahead.
