Medalla trying 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 post-mortem for particulars on the technicals and timeline, and Ben’s latest weblog posts ([1][2]) for a high-level evaluation. Consumer 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 unimaginable stressors on the testnet, it gave all shoppers an opportunity to harden themselves in opposition to among the wildest of situations. I can truthfully say that consumer software program is a lot extra sturdy following this incident. I am going to truly sleep slightly bit higher now main as much as eth2 mainnet launch.
Because the 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)!
Consumer variety is a should
Whereas there are numerous [excellent, viable, robust, usable, etc] eth2 shoppers below energetic growth, the community is at present dominated by a single consumer — Prysm.
There may be good historic purpose for this — Prysm has prioritized early testnets, group engagement, and usefulness for properly over a 12 months now. Kudos to the Prysmatic crew. Neighborhood constructing is concurrently extremely tough in addition to essential to our trade and open supply at massive.
That stated, the incident on Medalla was considerably amplified by the failure of the dominant Prysm consumer, 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 shoppers on Medalla, I can inform you first-hand that almost all shoppers are sturdy and properly documented, and all consumer groups are actively engaged on discord and github that will help you work by way of any points it’s possible you’ll run into.
Defend your self
Consumer variety not solely makes the eth2 consensus extra sturdy, 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 won’t 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 should 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 consumer vast 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 group efforts to attempt new shoppers, consumer groups are working arduous to make sure that switching shoppers is each straightforward and protected. With the addition of some cross-client standards, you will quickly have the ability to hop from one consumer to a different with minimal downtime and no threat of unintentional slashing.
Such requirements, which stop consumer lock-in, are a essential part to a sturdy eth2 community. Ease of adjusting software program will allow the group 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 major objectives of eth2 is to succeed in 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 vitality hungry proof-of-work consensus.
The transition to Section 1.5 is designed to be as seamless as potential to current customers and purposes. Eth1 shoppers stay the work horses for state, transactions, and execution. By leaving the overwhelming majority of this consumer layer untouched, Ethereum will have the ability to leverage current instruments and APIs to energy transactions and dapps, similar to they do right this moment.
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 may take a look at and play with a dockerized version of the eth1+eth2 demo, or should you desire to go a bit deeper, you’ll be able to construct and run from source.
Continued testing and audits, eyeballing Section 0 mainnet
Enterprise as standard 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 🚀
