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 may 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 latest weblog posts ([1][2]) for a high-level evaluation. Consumer groups labored via 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 purchasers an opportunity to harden themselves in opposition to a number of the wildest of eventualities. I can truthfully say that consumer software program is a lot extra sturdy following this incident. I will really sleep just a little 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 a lot of [excellent, viable, robust, usable, etc] eth2 purchasers beneath energetic improvement, the community is presently dominated by a single consumer — Prysm.
There may be good historic motive for this — Prysm has prioritized early testnets, neighborhood engagement, and usefulness for nicely over a 12 months now. Kudos to the Prysmatic workforce. Group constructing is concurrently extremely troublesome in addition to essential to our trade and open supply at giant.
That mentioned, the incident on Medalla was considerably amplified by the failure of the dominant Prysm consumer, 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 purchasers on Medalla, I can let you know first-hand that the majority purchasers are sturdy and nicely documented, and all consumer groups are actively engaged on discord and github that will help you work via any points you might run into.
Defend your self
Consumer variety not solely makes the eth2 consensus extra sturdy, 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 is not going to finalize as a result of >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 in the event 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 vital 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 neighborhood efforts to attempt new purchasers, consumer groups are working exhausting to make sure that switching purchasers is each simple and protected. With the addition of some cross-client standards, you may quickly be capable to hop from one consumer to a different with minimal downtime and no threat of unintentional slashing.
Such requirements, which forestall consumer lock-in, are a vital 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 consumer 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 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 doable to present customers and functions. Eth1 purchasers stay the work horses for state, transactions, and execution. By leaving the overwhelming majority of this consumer layer untouched, Ethereum will be capable to leverage present instruments and APIs to energy transactions and dapps, identical to they do at the 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 kind 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 in the event you favor 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 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 🚀
