Medalla wanting good (after some enjoyable)
A quiet testnet is a suspicious testnet.
For those who’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. 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. 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 number of the wildest of eventualities. I can actually say that consumer software program is a lot extra strong following this incident. I am going to really 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 energetic 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 energetic growth, the community is at the moment dominated by a single consumer — Prysm.
There’s good historic purpose for this — Prysm has prioritized early testnets, group engagement, and value for properly over a 12 months now. Kudos to the Prysmatic staff. Group constructing is concurrently extremely tough in addition to essential to our business and open supply at giant.
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 the majority shoppers are strong and properly documented, and all consumer groups are actively engaged on discord and github that will help you work by any points chances are you’ll run into.
Shield your self
Consumer variety not solely makes the eth2 consensus extra strong, but additionally helps shield 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 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. For those who 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 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 crucial error inflicting a consumer large outage. On this case, the chain can proceed to finalize (since 80% of the community are nonetheless collaborating). 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 simple to swap
Along with the group efforts to attempt new shoppers, consumer groups are working laborious to make sure that switching shoppers is each simple and protected. With the addition of some cross-client standards, you will quickly be capable of hop from one consumer to a different with minimal downtime and no danger of unintentional slashing.
Such requirements, which stop consumer lock-in, are a crucial part 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 consumer 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 present 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 an alternative of the present vitality 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 person layer untouched, Ethereum will be capable of 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 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’ll be able to 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 traditional 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 ????
