Medalla wanting good (after some enjoyable)
A quiet testnet is a suspicious testnet.
In the event you’ve adopted Medalla in any respect previously few weeks, you will be very conscious of the key 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 latest 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 unimaginable 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 will really 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 energetic validators and one other 12k within the activation queue (that is 12 days value)!
Consumer range is a should
Whereas there are numerous [excellent, viable, robust, usable, etc] eth2 shoppers underneath energetic improvement, the community is presently dominated by a single consumer — Prysm.
There’s good historic motive for this — Prysm has prioritized early testnets, group engagement, and usefulness for properly over a 12 months now. Kudos to the Prysmatic workforce. Neighborhood constructing is concurrently extremely troublesome 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 let you know first-hand that almost all 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 you could run into.
Defend your self
Consumer range not solely makes the eth2 consensus extra strong, but additionally helps shield you in excessive eventualities: as a result of 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 as a result of >33% outage. In the event you run client-A, you stand to lose an growing quantity every epoch that the finality outage continues (we name this an “inactivity leak”). Whereas if you happen to 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 important error inflicting a consumer vast outage. On this case, the chain can proceed to finalize (since 80% of the community are nonetheless collaborating). 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 situation above.
Purchasers making it straightforward to swap
Along with the group efforts to strive new shoppers, consumer groups are working onerous 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 danger of unintentional slashing.
Such requirements, which stop consumer lock-in, are a important element to a strong 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 major targets of eth2 is to achieve 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 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 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 present 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 a lot of transactions to the eth1 shard chain utilizing an unmodified metamask pockets.
You’ll be able to take a look at and play with a dockerized version of the eth1+eth2 demo, or if you happen to desire 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 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 🚀
