Medalla wanting good (after some enjoyable)
A quiet testnet is a suspicious testnet.
Should you’ve adopted Medalla in any respect up to now few weeks, you will be very conscious of the main 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. Shopper groups labored via 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 purchasers an opportunity to harden themselves in opposition to a number of the wildest of eventualities. I can truthfully say that shopper software program is a lot extra strong following this incident. I will really sleep a bit of 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 lots of [excellent, viable, robust, usable, etc] eth2 purchasers below lively improvement, the community is at the moment dominated by a single shopper — Prysm.
There’s good historic motive for this — Prysm has prioritized early testnets, neighborhood engagement, and value for effectively over a 12 months now. Kudos to the Prysmatic staff. 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 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 purchasers on Medalla, I can inform you first-hand that almost all purchasers are strong and effectively documented, and all shopper groups are actively engaged on discord and github that will help you work via any points chances are you’ll run into.
Shield your self
Shopper range not solely makes the eth2 consensus extra strong, but in addition helps defend you in excessive eventualities: as a result of 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 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 rising 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 steadiness 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 important error inflicting a shopper large 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 state of affairs above.
Shoppers making it straightforward to swap
Along with the neighborhood efforts to strive new purchasers, shopper groups are working arduous to make sure that switching purchasers is each straightforward and protected. With the addition of some cross-client standards, you will quickly be capable of 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 important element to a sturdy eth2 community. Ease of adjusting software program will allow the neighborhood to extra shortly resolve points (just like the Medalla incident) if/when a single shopper fails.
eth1+eth2 end-to-end demo
One of many main objectives of eth2 is to achieve Section 1.5 (aka The Merge), at which level the present 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 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 current customers and functions. Eth1 purchasers stay the work horses for state, transactions, and execution. By leaving the overwhelming majority of this consumer layer untouched, Ethereum will be capable of leverage current instruments and APIs to energy transactions and dapps, similar to they do in the present day.
To this finish, Mikhail (TXRX) and Guillaume (geth) not too long ago 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 various 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 in the event you choose to go a bit deeper, you possibly can construct and run from source.
Continued testing and audits, eyeballing Section 0 mainnet
Enterprise as normal 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 🚀
