Medalla wanting good (after some enjoyable)
A quiet testnet is a suspicious testnet.
In the event you’ve adopted Medalla in any respect prior to now few weeks, you will be very conscious of the foremost 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 way of the weekend following the incident, deploying sync and peering patches to resolve the extremely fragmented community.
Whereas the incident induced unbelievable stressors on the testnet, it gave all shoppers an opportunity to harden themselves in opposition to a number of the wildest of situations. I can actually say that shopper software program is a lot extra strong following this incident. I will really sleep just a little 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 value)!
Shopper range is a should
Whereas there are various [excellent, viable, robust, usable, etc] eth2 shoppers beneath lively growth, the community is presently dominated by a single shopper — Prysm.
There’s good historic cause for this — Prysm has prioritized early testnets, neighborhood engagement, and value for nicely over a 12 months now. Kudos to the Prysmatic crew. Group constructing is concurrently extremely tough in addition to essential to our business and open supply at giant.
That mentioned, the incident on Medalla was considerably amplified by the failure of the dominant Prysm shopper, 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 let you know first-hand that almost all shoppers are strong and nicely documented, and all shopper groups are actively engaged on discord and github that can assist you work by way of any points it’s possible you’ll run into.
Defend your self
Shopper range not solely makes the eth2 consensus extra strong, but in addition helps shield you in excessive situations: because of the anti-correlation incentives present in eth2, the extra your adverse 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 secure and on-line. Though the chain will proceed to be constructed by B and C, the chain is not going to finalize because of the >33% outage. In the event 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 in the event you run client-B or C, your stability is protected because you stay on-line. [Note — an inacivity leak is much worse than normal offline penalties.]
Suppose that as an alternative a minority client-B (with 20% of the community) experiences a essential error inflicting a shopper vast 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.
Purchasers making it straightforward to swap
Along with the neighborhood efforts to strive new shoppers, shopper groups are working arduous to make sure that switching shoppers is each straightforward and secure. With the addition of some cross-client standards, you will quickly have the ability to hop from one shopper to a different with minimal downtime and no threat of unintended slashing.
Such requirements, which stop shopper lock-in, are a essential part to a strong eth2 community. Ease of adjusting software program will allow the neighborhood to extra rapidly resolve points (just like the Medalla incident) if/when a single shopper fails.
eth1+eth2 end-to-end demo
One of many major objectives of eth2 is to succeed in Section 1.5 (aka The Merge), at which level the present Ethereum chain’s consensus might be built-in into eth2. From there on, the chain we all know and love might be constructed by proof-of-stake validators as an alternative of the present power hungry proof-of-work consensus.
The transition to Section 1.5 is designed to be as seamless as potential 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 have the ability to leverage present instruments and APIs to energy transactions and dapps, identical to they do right now.
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 kind of shards). Within the video of the demo launched, Mikhail sends various transactions to the eth1 shard chain utilizing an unmodified metamask pockets.
You may try and play with a dockerized version of the eth1+eth2 demo, or in the event you want to go a bit deeper, you may construct and run from source.
Continued testing and audits, eyeballing Section 0 mainnet
Enterprise as standard 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 🚀
