Layer 2 network Optimism [OP] completed the migration of its Goerli Testnet to Bedrock on 13 January.

According to Optimism, the Bedrock upgrade,

“Is the cheapest, fastest, and most advanced rollup architecture.”

The upgrade is expected to bring several improvements to the network, including offering lower data fees on the layer-1 Ethereum network, future-proofing of its proof-of-stake mechanism, support for multiple execution clients, and two-step withdrawals for assets bridged to the layer-2 system.

After successfully migrating its Goerli Testnet, Optimism will submit a proposal for a mainnet upgrade to the network’s governance team. The goal is for the upgrade to be implemented by the end of the first quarter of 2023.
