"eth Update Quick Facts"
: Medalla release preview, attack network news – bounty increased to 15,000 US dollars./r/ethstakertestnetYouTubeThe biggest news this week is the successful launch of the Medalla testnet. Medalla is a public test network that applies the specifications of the main network and encourages everyone to participate. If nothing unexpected happens, then Medalla will be the last large testnet before the launch of the beacon chain.Medalla was created eight seconds after 1300 UTC on Tuesday, August 4th, with a total of 20,084 validators registered. Ethereum Foundation and！
Organized a launch party: there were thirty or forty participants in the zoom meeting, and I sawthe Daily GweiI was also at the launch party
in the most recentInitial validator participation was low for a number of reasons, and it took 7 epochs (40 minutes) before we saw the network complete its first finalization. In fact, in reality, this is not a big deal, at least not as exaggerated as some media wrote. Anthony Sassano in hisA review of this incident was carried out in .
in the most recent
developer meeting
We discussed some of the reasons for the initial low participation: there were some problems setting up the bootstrap, and it was not introduced to the client in time; Some issues, so the team moved to a different client for the time being. Many large stakers are offline and may not be ready in time.

next roundThe bounty has been increased to 15,000 US dollars, the heart is not as good as action!BLS related progressYou may think that the changes related to BLS cryptographic signatures have been completed. Currently for edge cases in the (draft) IETF BLS signature standard there are。
some controversy<= SK , which may eventually bring the standardsome changesThe problem is with the validity of payloads signed with "infinity" signatures (identification points in the G2G2 group). That is, the private key is zero. From a cryptographic point of view, since all the data is the same, this is a meaningless signature. But on the face of it, this conforms to the current draft standard: 0 created a deposit . At the time, based on our understanding of the standard, it was accepted by all beacon chain clients as valid and without issue.AltaVistaFor our purposes, it is not very important how to solve this problem, and it makes more sense to explicitly state the invalidity of infinite signatures. We really need firm and clear definitions so that Eth2 clients can continue to reach consensus and ideally still remain compliant. ParaphraseAs soon as the Google version of the canonical notes came out, it compared my AltaVista version of the canonical notes. (Translator's Note:It is one of the most famous online search engines in the world. ) Okay, just kidding. VitalikEth2 specification notesPretty well written and without a doubt a major resource for learning. However, I will continue to complete my version anyway. These two versions have different emphases, and I believe the two can coexist happily. I also plan to add some additional features, such as better internal navigation slowly rolling out. But in any case, I believe that the Internet is now about Beacon Chain Genesis Explanation ArticleIt's just the one I wrote. Before the release of Medalla, many people, including developers, had a lot of doubts about it, so I wrote a short introduction. Here are some guides on how to run a node on Medalla. Sorry if I missed your post, here is some info I noticed this week:"Instructions on how to set up an Eth2 client on the testnet Medalla"as well asSomer Esat released two guides, that is, how to stake on the testnet Medalla based on the Ubuntu server, respectivelyBased on Lighthouse client as well asPrysm clientExplain. CoinCashew published an articleBased on Ubuntu server and Teku clientpledge guide. There are r/ethstakers on howGuaranteed pledge securitySome guides cover this, some don't, although it's fairly important. Improve point-to-point connectivity"Protecting the Authenticator Key"。 , which is good advice for all clients.Attestant's Jim McDonald continues his conscience science series with the release of"Protecting the Authenticator Key"beaconcha.inJim also figured out a way to define the verifier's prove efficiency. The speed at which clients package their proofs (votes) into the beacon chain is the primary measure of client performance, as this will affect how much rewards validator nodes can earn. This is a very useful metric,It has been incorporated into the validator overview interface.Alon Muroch continues his series on BLS signatures with the release of"Main Concepts of Pairing". Alon's company Blox is also. In other interesting news, Ledger added in a recent Nano-X update Support for BLS12-381 curves.
