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 may 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 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 somewhat 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 range is a should
Whereas there are various [excellent, viable, robust, usable, etc] eth2 shoppers below energetic growth, 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 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 trade 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 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 the majority shoppers are sturdy and properly documented, and all shopper groups are actively engaged on discord and github that can assist you work by any points chances are you’ll run into.
Defend your self
Consumer range not solely makes the eth2 consensus extra sturdy, but in addition helps shield you in excessive eventualities: as a result of anti-correlation incentives present in eth2, the extra your detrimental 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 as a result of >33% outage. Should 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 when you 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 a substitute a minority client-B (with 20% of the community) experiences a essential 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 working client-B, solely obtain minor penalties in comparison with the primary state of affairs above.
Purchasers making it simple to swap
Along with the neighborhood efforts to attempt new shoppers, shopper groups are working exhausting to make sure that switching shoppers is each simple and protected. With the addition of some cross-client requirements, you may quickly have the ability to hop from one shopper to a different with minimal downtime and no threat of unintentional slashing.
Such requirements, which forestall shopper lock-in, are a essential part to a strong eth2 community. Ease of adjusting 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 major targets of eth2 is to achieve Section 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 Section 1.5 is designed to be as seamless as attainable 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 at present.
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 try and play with a dockerized model of the eth1+eth2 demo, or when you favor to go a bit deeper, you may construct and run from supply.
Continued testing and audits, eyeballing Section 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 🚀
