The hotly anticipated „London“ Ether hardfork currently has a set block height for three Ether testnets — a important penultimate step towards a complete mainnet launch.
In a blog post about the Ether Foundation’s site, Ether core programmer Tim Beiko wrote that the Ropsten, Goerli, and Rinkeby testnets finally have set block heights at which London will go live, with Ropsten expected to be the first at block 10499401, or even sometime on June 24th. Goerli is predicted to be following on June 30th, and Rinkeby on July 7th.
A release schedule for the all-important mainnet upgrade is still being determined, however.
When the upgrade has successfully been actuated on these systems, a block will be set to your Ether mainnet and also be communicated on this site and in other places,“ Beiko wrote.
The London hard disk upgrade comprises five Ether Improvement Proposal (EIP) updates, however, the star of the show is EIP-1559. An overhaul of Ether’s existing fee arrangement, EIP-1559 is expected to reduce gas prices for users significantly. It may also cut to miner revenues by upwards of 50%, however, which has led to a grublings about a“miner revolt“ that has mostly failed to materialize.

The upgrade is regarded as one of many bullish catalysts on the horizon to get Ether, at the least of which is the ETH 2.0 upgrade. ETH 2.0 will transition the system into a more scalable proof-of-stake consensus mechanism, which will greatly decrease the energy intake of validation blocks.
The site post noted that such significant system updates to a decentralized system is a feat of communicating.
„The decentralized character of blockchain systems makes a community upgrade more difficult. Network updates in a blockchain require communication and cooperation with the community, as well as with the developers of the various Ether customers in order for the transition to go smoothly.“
Three Ether testnets finally have a setup for the London hardfork, an integral step towards a complete mainnet implementation.
