Following a successful testnet deployment, the London upgrade is now ready to be triggered on the Ethereum mainnet, which is anticipated to be live on block 12 965 000 between August 3-5, 2021, according to Bloqport.
To be compatible with the London update, node operators must upgrade the client version they use. The performances of each client listed below support London on the Ethereum mainnet.
These updates differ from prior announcements that supported London on testnets. Previous versions of the client did not support London on the mainnet.

A network update is a modification to the Ethereum protocol that introduces new regulations to improve the project. Because blockchain systems are decentralized, network upgrades are more challenging.
To ensure a smooth transition, network updates on a blockchain involve collaborative efforts with the community and the developers of the many Ethereum clients.
Modifications to the network are incorporated into the multiple Ethereum clients, such as Geth, Erigon, Besu, and Nethermind, once the community agrees on which improvements should be included in the update.
At a specific block number, the protocol modifications are enabled. Any nodes that have not been updated to the new ruleset will be left on the old chain, where the prior rules still apply.
