Medalla trying 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 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. Consumer 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 shoppers an opportunity to harden themselves in opposition to a few of the wildest of situations. I can actually say that shopper software program is a lot extra strong following this incident. I am going to truly sleep slightly bit higher now main as much as eth2 mainnet launch.
For the reason that 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)!
Consumer variety is a should
Whereas there are lots of [excellent, viable, robust, usable, etc] eth2 shoppers underneath lively growth, the community is at the moment dominated by a single shopper — Prysm.
There may be good historic motive for this — Prysm has prioritized early testnets, group engagement, and usefulness for nicely over a yr now. Kudos to the Prysmatic group. Group constructing is concurrently extremely tough in addition to essential to our business and open supply at massive.
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 shoppers on Medalla, I can let you know first-hand that the majority shoppers are strong and nicely 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
Consumer variety not solely makes the eth2 consensus extra strong, but in addition helps defend you in excessive situations: 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 won’t finalize because of the >33% outage. In the event 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 for those who 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 crucial error inflicting a shopper extensive outage. On this case, the chain can proceed to finalize (since 80% of the community are nonetheless collaborating). There isn’t any “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 shoppers, shopper groups are working onerous to make sure that switching shoppers is each simple 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 danger of unintended slashing.
Such requirements, which forestall shopper lock-in, are a crucial element to a sturdy eth2 community. Ease of adjusting software program will allow the group 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 targets of eth2 is to succeed in Part 1.5 (aka The Merge), at which level the prevailing Ethereum chain’s consensus will likely be built-in into eth2. From there on, the chain we all know and love will likely 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 current 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 have the ability to leverage current instruments and APIs to energy transactions and dapps, identical to they do in the present day.
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 type of shards). Within the video of the demo launched, Mikhail sends numerous 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 for those who favor to go a bit deeper, you’ll be able to construct and run from source.
Continued testing and audits, eyeballing Part 0 mainnet
Enterprise as normal 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 🚀
