According to Medalla, the Ethereum 2.0 multi-client test network, as of now, there are more than 26,000 active verification nodes and they are currently running well. Medalla has always followed the mainnet specifications and has made significant improvements in size and complexity compared to other testnets. Four major issues have been identified since the testnet was released last week, and two of them have been fixed so far. The first problem fixed is that the increase in the number of verifications in Medalla (compared to the testnet Altona) exposed the limitations of the glue code between libp2p and the beacon node. The second is an authentication processing error. The two issues currently under investigation are that the Medalla block authentication limit is 128, which means that the limit of the signature library Milagro has now been reached. In order to solve this problem, we are in the process of switching to blst (expected to be completed at the weekend). Another problem is that there is a race condition for incoming and outgoing requests from the same peer, which causes some problems with Lighthouse, and we are working hard to solve this problem. Chain Wen previously reported that Medalla was officially launched at 21:00 on August 4th. If Medalla is running stable, the next step is currently the mainnet launch. Medalla’s previous multi-client testnet was mainly run by the client team and EF members. With the launch of the Medalla testnet, the stability and health of the Ethereum chain will be almost completely in the hands of the community.
