Medalla trying good (after some enjoyable)
A quiet testnet is a suspicious testnet.
If you happen to’ve adopted Medalla in any respect up to now few weeks, you may 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 current weblog posts ([1][2]) for a high-level evaluation. Shopper groups labored by 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 among the wildest of situations. I can truthfully say that shopper software program is a lot extra sturdy following this incident. I will truly sleep a 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 range is a should
Whereas there are lots of [excellent, viable, robust, usable, etc] eth2 purchasers beneath energetic growth, the community is at the moment dominated by a single shopper — Prysm.
There may be good historic purpose for this — Prysm has prioritized early testnets, group engagement, and value for properly over a yr now. Kudos to the Prysmatic crew. Neighborhood 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 group, 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 the majority purchasers are sturdy and properly documented, and all shopper groups are actively engaged on discord and github that will help you work by any points you could run into.
Defend your self
Shopper range not solely makes the eth2 consensus extra sturdy, but additionally helps defend you in excessive situations: as a result of anti-correlation incentives present in eth2, the extra your unfavorable 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. 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 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 crucial 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.
Purchasers making it simple to swap
Along with the group efforts to strive new purchasers, shopper groups are working exhausting to make sure that switching purchasers is each simple and secure. With the addition of some cross-client standards, you may 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 crucial part to a sturdy eth2 community. Ease of fixing software program will allow the group 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 Part 1.5 (aka The Merge), at which level the prevailing 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 power hungry proof-of-work consensus.
The transition to Part 1.5 is designed to be as seamless as doable to present 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 present instruments and APIs to energy transactions and dapps, identical to they do right now.
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 variety 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 for those who desire to go a bit deeper, you possibly can construct and run from source.
Continued testing and audits, eyeballing Part 0 mainnet
Enterprise as ordinary 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 🚀
