The medal appears good (after the occasion)
A silent testnet is a suspect testnet.
Should you’ve been following Medalla at everywhere in the previous few weeks, you will be nicely conscious of the foremost five-day incident that passed off on Friday, August 14th. Try Prysm’s put up mortem for technical and timeline particulars, and Ben’s current weblog posts ([1][2]) for high-level evaluation. Consumer groups labored via the weekend following the incident, deploying synchronization and peering patches to handle the extremely fragmented community.
Whereas the incident brought on unbelievable stressors on the testnet, it gave all clients an opportunity to harden themselves towards a few of the wildest eventualities. I can actually say that the shopper software program is many stronger after this incident. I will truly sleep somewhat higher now earlier than beginning the eth2 mainnet.
Because the incident, Medalla has been working fairly easily: now with 39k lively validators and one other 12k queued for activation (that is 12 days’ value)!
A wide range of shoppers is crucial
Whereas there are a lot of of them [excellent, viable, robust, usable, etc] eth2 shoppers in lively growth, the community is presently dominated by one shopper — Prysm.
There is a good historic cause for this — Prysm prioritized early testnets, group engagement, and usefulness for greater than a 12 months. Kudos to the Prysmatic crew. Neighborhood constructing is each extremely tough and essential to our business and open supply generally.
Nevertheless, the Medalla incident was considerably amplified by the failure of the dominant Prysm shopper, and as we transfer in direction of the mainnet, we, as a group, should they consciously attempt to right it. 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 nicely documented, and all shopper groups are actively engaged on discord and github that can assist you clear up any issues you would possibly encounter.
Shield your self
Consumer range not solely makes the eth2 consensus extra strong, but in addition helps shield you in excessive eventualities: because of the anti-correlation incentives present in eth2, the extra your damaging conduct is correlated with the conduct of others, the extra you lose.
For instance, suppose 60% of the community is down for days as a consequence of an outage in Consumer-A, however Consumer-B and Consumer-C stay steady and on-line. Though the chain will proceed to construct B and C, the chain won’t be finalized as a consequence of >33% breaks. Should you begin client-A, you possibly can lose growing the quantity of every epoch by which the outage of finiteness continues (we name this “inactivity leakage”). Whereas if you happen to begin client-B or C, your steadiness is protected since you might be on-line. [Note — an inacivity leak is much worse than normal offline penalties.]
Suppose as a substitute that minority client-B (with 20% of the community) experiences a important error that causes your complete shopper to go down. On this case, the chain can proceed to be finalized (as a result of 80% of the community continues to be collaborating). There isn’t any “inactivity leak” of offline validators, simply regular penalties. So these working client-B solely get minor penalties in comparison with the primary situation above.
Shoppers that facilitate substitute
Along with group efforts to check out new shoppers, shopper groups are working arduous to make sure that shopper switching is i simple and secure. With the addition of some inter-client requirementsyou will quickly be capable of leap from one shopper to a different with minimal downtime and no threat of unintended chopping.
Such requirements, which forestall shopper lock-in, are a important element of a sturdy eth2 community. The benefit of fixing software program will enable the group to resolve points (just like the Medallo incident) sooner if/when one shopper fails.
eth1+eth2 end-to-end demo
One of many main objectives of eth2 is to achieve stage 1.5 (aka The Merge), at which level the prevailing consensus of the Ethereum chain can be built-in into eth2. From that time ahead, the chain we all know and love can be constructed by proof-of-stake validators as a substitute of the present energy-hungry proof-of-work consensus.
The transition to Part 1.5 is designed to be as seamless as attainable for present customers and functions. Eth1 shoppers stay the initiators of states, transactions and executions. By leaving the overwhelming majority of this consumer layer untouched, Ethereum will be capable of leverage present instruments and APIs to run transactions and dapps, simply as they do at present.
To this finish, Mikhail (TXRX) and Guillaume (geth) just lately revealed end-to-end demo beacon chain with a number of items (with the eth1 chain as a type of fragments). Within the posted demo video, Mikhail sends a collection of transactions to the eth1 shard chain utilizing unchanged metamask pockets.
You may examine and play with dockerized model eth1+eth2 demo, or if you happen to favor to go somewhat deeper, you possibly can construct and run from the supply.
Continued testing and revisions, observing Part 0 mainnet
Enterprise as normal on this entrance.
Consumer groups are working their asses off, auditors are digging in each nook and cranny and preparations are underway to launch the mainnet 🚀
