Reported by Coindesk, one of the biggest rollup networks on Ethereum is finally gearing up its systems for prime time.
Optimism, a "layer-2" blockchain, bundles up user transactions and settles them on Ethereum for cheap. It has played a lead role in expanding accessibility to the second-largest blockchain ecosystem by market capitalization – and serves as the template for the publicly traded crypto exchange Coinbase's own layer-2 network, Base.
But there's a catch to using Optimism today: Fault proofs, a component of the setup considered crucial for security, don't even exist. That's soon set to change.
On Tuesday, OP Labs, the main development firm behind the Optimism blockchain, will begin testing fault proofs on Ethereum's Sepolia test network. The new deployment comes a few months after Optimism launched an initial version of fault proofs on Goerli, another Ethereum test network, in October. Karl Floersch, co-founder of Optimism and CEO of OP Labs, expects the proofs to reach Ethereum's main network later this year, with the Sepolia deployment bringing the team closer than ever to this goal.
The tech will help secure withdrawals from the network, and it has been a long time coming – exposing the Optimism ecosystem to embarrassing criticism from advocates of rival blockchains.
