Receive mainnet merge

yesterday Consensus layer callClient engineers agreed on mainnet parameters for Merge, the Bellatrix era. 144896 And Paris TTD 58750000000000000000000 (tentative). TTD is based on proof-of-work difficulty, so it is a bit difficult to estimate accurately. that much target date The date is September 15, 2022, but this estimate may be off by a week. All Core Dev currency estimates will be reconfirmed this week and TTDs will be confirmed or final adjustments made to better achieve the target date.

NOTE💡: The merge consists of two upgrades. bellatrix At the consensus layer fly In the execution layer.

Bellatrix upgrades the beacon chain to be “merge-aware,” embedding merge logic into the beacon chain as validators begin diligently monitoring the proof-of-work chain to initiate merge transitions. Bellatrix becomes active in the era of your choice.

Paris is a merge transition itself, where the Ethereum mainnet hot-swaps consensus from proof-of-work to proof-of-stake on the beacon chain. The Paris upgrade is activated at the selected Terminal Total Difficulty (TTD).

⚠️ Everyone join hands ⚠️

Stakers, infrastructure providers, users and community members — this is your warning. Merge mainnet sequence be engaged. Over the next five weeks, stay tuned, check for updates, stay agile, and be prepared for anything. Below are the high-level dates and events we expect to unfold.

• (2022/08/18) — Re-evaluated and finalized the TTD at the All Core Devs meeting.
• (2022/08/18 ~ 2022/8/22) — EL and CL teams have stopped releasing mainnet software.
• (2022/08/23) — Client resources, EF blog, and other community and infrastructure announcements about final parameters and releases
• (2022/09/06 11:34:47 AM UTC) — Bellatrix mainnet upgrade
  
  • All stakers ~ have to Please upgrade to an EL+CL merge-ready node before this time.
  • All infrastructure providers, users and community members must Please upgrade your PoW nodes to EL+CL merge ready nodes before this time.

• (Estimated: 2022/9/15) — Paris mainnet merge transition
  
  • All infrastructure providers, users and community members ~ have to Please upgrade to an EL+CL merge-ready node before this time. Plan your system configuration at least a week in advance, ideally before Bellatrix.

Between the announcement of the initial mainnet release and the final Merge transition, users should diligently monitor client channels, the EF blog, and other public resources for new information. In particular, the client team can release the final version. candied Users must upgrade their software version within this period, if possible.

A huge shout out to the engineers, researchers, and community members who have worked tirelessly and poured countless hours into this work. Merge sequence started 🚀
