- Merge progress — minor spec updates, engineering full steam forward 🚂
- No progress in consumer range. Be egocentric, run a minority consumer!
To start with — incredible work to all the engineering groups on the Kintsugi dash, which culminated within the launch of the Kintsugi Merge testnet. It’s unimaginable to see 3 execution shoppers and 5 consensus shoppers for a complete of 15 completely different pairings working on a unified entrance.
Kintsugi🍵, the primary long-standing Merge testnet, was not with out pleasure. The #TestingTheMerge effort hammered the testnet with transactions, dangerous blocks, and a variety of different chaotic inputs, effervescent up some bugs in state transition, sync, and extra. We look forward to finding such bugs in early testnets, however with every iteration, shoppers change into increasingly steady.
Kiln reboot 🔥🧱
Groups recognized an essential concern a number of weeks in the past. This was a mismatch within the engine API (how the PoS consensus-layer drives the execution-layer) semantics associated to how execution-layer shoppers truly perform in observe. The tl;dr is that, in some contexts, the consensus-layer was by chance inducing sudden load on the execution-layer.
Engineers then realized that if the engine API semantics have been barely extra versatile, the 2 layers may work extra harmoniously. This led to a delicate, but vital, modification of the engine API and a associated breaking spec launch.
Immediately, the Kiln spec🔥🧱 was launched, and engineers are busy knocking out the modifications. On the finish of this dash, groups purpose to carry production-ready implementations to a brand new testnet for public consumption. Maintain your eyes peeled for the right way to take part.
From there, groups will transition public testnets to proof-of-stake earlier than making mainnet preparations.
Shopper range metrics
Michael Sproul launched a brand new wave of client diversity metrics utilizing his novel fingerprinting mechanism. Sadly, the consumer distribution of validating nodes has not budged prior to now 6 months.
The range of consensus-layer consumer implementations allows Ethereum and its customers to have a singular and strong resilience to software program failures and assaults. Customers obtain some resiliance by utilizing a minority consumer whatever the community make-up, however the community itself positive factors resiliance at a number of key validator distribution thresholds.
If a single consumer:
- Doesn’t exceed 66.6%, a fault/bug in a single consumer can’t be finalized
- Doesn’t exceed 50%, a fault/bug in a single consumer’s forkchoice can’t dominate the top of the chain
- Doesn’t exceed 33.3%, a fault/bug in a single consumer can’t disrupt finality
From the seems to be of the fingerprinting mechanism, Prysm nonetheless sits above the 66.6% mark.
I need to give an enormous shoutout to the groups, people, and communities taking consumer range significantly (exhibit A, exhibit B). Operating a minority consumer just isn’t solely wholesome for the community however can also be safer for the person consumer’s funds.
Be egocentric (rational)! Run a minority consumer 🚀
