Medalla wanting good (after some enjoyable)
A quiet testnet is a suspicious testnet.
Should you’ve adopted Medalla in any respect prior to now few weeks, you will be very conscious of the most important 5-day incident that occured on Friday, August 14th. Take a look at Prysm’s post-mortem for particulars on the technicals and timeline, and Ben’s current weblog posts ([1][2]) for a high-level evaluation. Consumer groups labored via the weekend following the incident, deploying sync and peering patches to resolve the extremely fragmented community.
Whereas the incident induced unimaginable stressors on the testnet, it gave all shoppers an opportunity to harden themselves in opposition to a number of the wildest of eventualities. I can truthfully say that consumer software program is a lot extra strong following this incident. I will really sleep a bit bit higher now main as much as eth2 mainnet launch.
Because the incident, Medalla has chugged alongside fairly easily: now with 39k lively validators and one other 12k within the activation queue (that is 12 days price)!
Consumer range is a should
Whereas there are a lot of [excellent, viable, robust, usable, etc] eth2 shoppers below lively improvement, the community is presently dominated by a single consumer — Prysm.
There may be good historic cause for this — Prysm has prioritized early testnets, group engagement, and value for nicely over a yr now. Kudos to the Prysmatic workforce. Group constructing is concurrently extremely troublesome in addition to essential to our business and open supply at massive.
That stated, the incident on Medalla was considerably amplified by the failure of the dominant Prysm consumer, and as we transfer towards mainnet, we, as a group, should consciously search to treatment this. As somebody who has tried all of the eth2 shoppers on Medalla, I can let you know first-hand that the majority shoppers are strong and nicely documented, and all consumer groups are actively engaged on discord and github that can assist you work via any points it’s possible you’ll run into.
Defend your self
Consumer range not solely makes the eth2 consensus extra strong, but in addition helps shield you in excessive eventualities: as a result of anti-correlation incentives present in eth2, the extra your destructive behaviour is correlated with that of others, the extra you extra you stand lose.
For instance, suppose 60% of the community goes offline for a number of days due an outage in client-A, however client-B and client-C stay steady and on-line. Though the chain will proceed to be constructed by B and C, the chain won’t finalize as a result of >33% outage. Should you run client-A, you stand to lose an growing quantity every epoch that the finality outage continues (we name this an “inactivity leak”). Whereas for those who run client-B or C, your steadiness is protected because you stay on-line. [Note — an inacivity leak is much worse than normal offline penalties.]
Suppose that as a substitute a minority client-B (with 20% of the community) experiences a vital error inflicting a consumer extensive outage. On this case, the chain can proceed to finalize (since 80% of the community are nonetheless collaborating). There isn’t a “inactivity leak” incurred by the offline validators, solely regular penalties. So these operating client-B, solely obtain minor penalties in comparison with the primary state of affairs above.
Shoppers making it simple to swap
Along with the group efforts to strive new shoppers, consumer groups are working arduous to make sure that switching shoppers is each simple and secure. With the addition of some cross-client standards, you will quickly be capable to hop from one consumer to a different with minimal downtime and no danger of unintentional slashing.
Such requirements, which stop consumer lock-in, are a vital element to a strong eth2 community. Ease of adjusting software program will allow the group to extra rapidly resolve points (just like the Medalla incident) if/when a single consumer fails.
eth1+eth2 end-to-end demo
One of many major objectives of eth2 is to achieve Section 1.5 (aka The Merge), at which level the present Ethereum chain’s consensus shall be built-in into eth2. From there on, the chain we all know and love shall be constructed by proof-of-stake validators as a substitute of the present vitality hungry proof-of-work consensus.
The transition to Section 1.5 is designed to be as seamless as doable to present customers and functions. Eth1 shoppers stay the work horses for state, transactions, and execution. By leaving the overwhelming majority of this person layer untouched, Ethereum will be capable to leverage present instruments and APIs to energy transactions and dapps, identical to they do at this time.
To this finish, Mikhail (TXRX) and Guillaume (geth) lately launched an end-to-end demo of a multi-sharded beacon chain (with an eth1 chain as a type of shards). Within the video of the demo launched, Mikhail sends quite a lot of transactions to the eth1 shard chain utilizing an unmodified metamask pockets.
You’ll be able to try and play with a dockerized version of the eth1+eth2 demo, or for those who want to go a bit deeper, you’ll be able to construct and run from source.
Continued testing and audits, eyeballing Section 0 mainnet
Enterprise as traditional on this entrance.
Consumer groups are working their asses off, auditors are digging into each nook and cranny, and preparations are being made for mainnet launch 🚀
