Medalla trying good (after some enjoyable)
A quiet testnet is a suspicious testnet.
If you happen to’ve adopted Medalla in any respect prior to now few weeks, you will be very conscious of the main 5-day incident that occured on Friday, August 14th. Try Prysm’s post-mortem for particulars on the technicals and timeline, and Ben’s latest weblog posts ([1][2]) for a high-level evaluation. Shopper groups labored by means of 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 towards a few of the wildest of eventualities. I can actually say that consumer software program is a lot extra sturdy following this incident. I am going to truly sleep a little bit bit higher now main as much as eth2 mainnet launch.
For the reason that incident, Medalla has chugged alongside fairly easily: now with 39k energetic validators and one other 12k within the activation queue (that is 12 days price)!
Shopper variety is a should
Whereas there are numerous [excellent, viable, robust, usable, etc] eth2 shoppers below energetic growth, the community is at the moment dominated by a single consumer — Prysm.
There’s good historic purpose for this — Prysm has prioritized early testnets, neighborhood engagement, and value for properly over a yr now. Kudos to the Prysmatic crew. Group constructing is concurrently extremely troublesome in addition to essential to our business and open supply at massive.
That mentioned, the incident on Medalla was considerably amplified by the failure of the dominant Prysm consumer, and as we transfer towards mainnet, we, as a neighborhood, should consciously search to treatment this. As somebody who has tried all of the eth2 shoppers on Medalla, I can inform you first-hand that the majority shoppers are sturdy and properly documented, and all consumer groups are actively engaged on discord and github that will help you work by means of any points you could run into.
Shield your self
Shopper variety not solely makes the eth2 consensus extra sturdy, but additionally helps shield you in excessive eventualities: as a result of anti-correlation incentives present in eth2, the extra your damaging 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 is not going to finalize as a result of >33% outage. If you happen to run client-A, you stand to lose an growing quantity every epoch that the finality outage continues (we name this an “inactivity leak”). Whereas should you 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 essential error inflicting a consumer extensive outage. On this case, the chain can proceed to finalize (since 80% of the community are nonetheless taking part). 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 situation above.
Shoppers making it straightforward to swap
Along with the neighborhood efforts to attempt new shoppers, consumer groups are working onerous to make sure that switching shoppers is each straightforward and secure. With the addition of some cross-client standards, you will quickly be capable of hop from one consumer to a different with minimal downtime and no danger of unintentional slashing.
Such requirements, which forestall consumer lock-in, are a essential element to a strong eth2 community. Ease of fixing software program will allow the neighborhood 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 main objectives of eth2 is to achieve Part 1.5 (aka The Merge), at which level the prevailing Ethereum chain’s consensus will probably be built-in into eth2. From there on, the chain we all know and love will probably be constructed by proof-of-stake validators as a substitute of the present vitality hungry proof-of-work consensus.
The transition to Part 1.5 is designed to be as seamless as attainable 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 of leverage present instruments and APIs to energy transactions and dapps, identical to they do at present.
To this finish, Mikhail (TXRX) and Guillaume (geth) just 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 a lot of transactions to the eth1 shard chain utilizing an unmodified metamask pockets.
You possibly can take a look at and play with a dockerized version of the eth1+eth2 demo, or should you choose to go a bit deeper, you may construct and run from source.
Continued testing and audits, eyeballing Part 0 mainnet
Enterprise as typical on this entrance.
Shopper groups are working their asses off, auditors are digging into each nook and cranny, and preparations are being made for mainnet launch 🚀
