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 key 5-day incident that occured on Friday, August 14th. Try Prysm’s autopsy for particulars on the technicals and timeline, and Ben’s latest weblog posts ([1][2]) for a high-level evaluation. Consumer 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 unbelievable stressors on the testnet, it gave all shoppers an opportunity to harden themselves in opposition to among the wildest of eventualities. I can actually 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.
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 various [excellent, viable, robust, usable, etc] eth2 shoppers beneath lively improvement, the community is presently dominated by a single shopper — Prysm.
There may be good historic motive for this — Prysm has prioritized early testnets, neighborhood engagement, and value for properly over a yr now. Kudos to the Prysmatic workforce. Neighborhood constructing is concurrently extremely troublesome in addition to essential to our trade 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 inform you first-hand that almost all shoppers are sturdy and properly documented, and all shopper groups are actively engaged on discord and github that will help you work by means of any points you might run into.
Shield your self
Consumer range not solely makes the eth2 consensus extra sturdy, but in addition helps defend you in excessive eventualities: because of the anti-correlation incentives present in eth2, the extra your unfavourable 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 because of the >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 case 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 a substitute a minority client-B (with 20% of the community) experiences a vital error inflicting a shopper extensive outage. On this case, the chain can proceed to finalize (since 80% of the community are nonetheless taking part). There is no such thing as a “inactivity leak” incurred by the offline validators, solely regular penalties. So these working 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 attempt new shoppers, shopper groups are working laborious to make sure that switching shoppers is each straightforward and secure. With the addition of some cross-client requirements, you will quickly be capable to hop from one shopper to a different with minimal downtime and no threat of unintended slashing.
Such requirements, which forestall shopper lock-in, are a vital element to a sturdy 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 shopper fails.
eth1+eth2 end-to-end demo
One of many main targets of eth2 is to succeed in Part 1.5 (aka The Merge), at which level the prevailing Ethereum chain’s consensus can be built-in into eth2. From there on, the chain we all know and love can 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 shoppers stay the work horses for state, transactions, and execution. By leaving the overwhelming majority of this consumer layer untouched, Ethereum will be capable to leverage present instruments and APIs to energy transactions and dapps, similar 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 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 take a look at and play with a dockerized model of the eth1+eth2 demo, or in case you desire to go a bit deeper, you may construct and run from supply.
Continued testing and audits, eyeballing Part 0 mainnet
Enterprise as common 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 🚀
