tl;dr
Merge sequence engaged 🚀
Mainnet Merge incoming
Yesterday on the Consensus Layer call, consumer engineers agreed on Mainnet parameters for the Merge — a Bellatrix epoch of 144896 and a Paris TTD of 58750000000000000000000 (tentative). The TTD relies on Proof-of-Work problem and is thus a bit exhausting to estimate exactly. The goal date is September 15, 2022, however this estimate might need even per week of error. On this coming week’s All Core Dev name estimates shall be re-checked, and the TTD will both be confirmed or a closing adjustment shall be made to raised hit the goal date.
Reminder💡: The Merge consists of a sequence of two upgrades — Bellatrix on the Consensus Layer adopted by Paris on the Execution Layer.
Bellatrix upgrades the Beacon Chain to be “Merge conscious”, embedding the Beacon Chain with the Merge logic as validators start dilligently monitoring the Proof-of-Work chain to provoke the Merge transition. Bellatrix is activated on the chosen epoch.
Paris is the Merge transition itself, during which Ethereum Mainnet hot-swaps its consensus from Proof-of-Work to the Beacon Chain’s Proof-of-Stake. The Paris improve prompts on the chosen Terminal Whole Problem (TTD).
⚠️ All arms on deck ⚠️
Stakers, infrastructure suppliers, customers, and group members — that is your warning. The Merge mainnet sequence is engaged. For the following ~5 weeks, keep tuned, look ahead to updates, stay agile, and be prepared for something. The next is the excessive degree of dates and occasions anticipated to unfold:
- [2022/08/18] — TTD reassessed and finalized on All Core Devs name
- [2022/08/18 to 2022/8/22] — EL and CL groups reduce Mainnet software program releases
- [2022/08/23] — Consumer sources, EF weblog, and different group and infrastructure bulletins of ultimate parameters and releases
- [2022/09/06 11:34:47am UTC] — Bellatrix Mainnet improve
- All stakers should improve to EL+CL Merge-ready nodes earlier than this time
- All infrastructure suppliers, customers, and group members ought to improve PoW nodes to EL+CL Merge-ready nodes earlier than this time
- [Estimated: 2022/9/15] — Paris Mainnet Merge transition
- All infrastructure suppliers, customers, and group members should improve to EL+CL Merge-ready nodes earlier than this time. Plan on configuring programs no less than one week prematurely and ideally earlier than Bellatrix
Between preliminary mainnet launch bulletins and the ultimate Merge transition, customers should stay diligent — monitoring consumer channels, the EF weblog, and different public sources for any new info. Particularly, consumer groups may launch closing hardened variations of their software program on this time-frame and, if doable, customers ought to improve.
Large shout-out to the engineers, researchers, and group members which have labored tirelessly, placing numerous hours into this. Merge sequence engaged 🚀
