Optimism, an Ethereum L2, scaling platform, has announced a significant Mainnet upgrade dubbed Bedrock, scheduled for June 6. The upgrade will necessitate two to four hours of outage during which deposits, withdrawals, and transactions will be unavailable.
On upgrade day, transactions, deposits, and withdrawals will be unavailable for the duration of the downtime, and the OP Mainnet chain will not be progressing.

The upgrade will enhance the security and resiliency of the OP Mainnet bridge while reducing fees significantly. Backward compatibility is a major design objective of the upgrade.
On upgrade day, the upgrade will proceed as follows: Withdrawals and deposits on the legacy network will be suspended. The legacy sequencer will no longer handle transactions. The smart contracts on Level 1 will be upgraded, and an irregular state transition will be carried out on L2.
There will be a distribution of the contract addresses, binaries, and data directories required to operate nodes on the new network. After two to four hours, the Bedrock sequencer will begin operating again, and deposits and withdrawals will be enabled again. Backwards compatibility is one of the primary design objectives of the upgrade.
Optimism employs optimistic rollups, a technology that enables multiple transactions to be bundled into a single transaction on the Ethereum blockchain. On its platform, the network has approximately $863 million in secured assets. “Bedrock makes it easy to contribute to client diversity,” the foundation stated, adding that additional information will be accessible via a mission control website.
If you are a node operator, you will need to spin up a brand new node deployment for Bedrock. Bedrock Mission Control, linked in the first tweet, contains all of the information needed.

Bedrock is designed to have the smallest potential impact on Ethereum. Ethereum equivalence plus reduced complexity equals less space for bugs and easier ecosystem developer participation. The upgrade will substantially reduce fees and enhance security and resiliency.
