  • Medalla is the final testnet before the launch of the Eth 2.0 network, which is tentatively expected by year’s end.
  • The correct number of peers joined the tesnet to consider it workable, according to a tweet from the Ethereum Foundation’s Hudson Jameson.
  • As reported by CoinDesk, Medalla was one of many Eth 2.0 testnets over 2019 and 2020. Unlike the other testnets, however, Medalla was public – meaning network validators were not centrally coordinated by developer teams.
  • Over 20,000 validators have joined the network with some 650,000 ether staked, according to the Beaconcha.in block explorer. (Each testnet uses its own tokens not equivalent to real ETH.)
  • Medalla was joined by five clients including Prysmatic Labs’ Prysm, ChainSafe’s Lodestar, PegaSys’ Teku, Status’ Nimbus and Sigma Prime’s Lighthouse.
  • Eth 2.0 encapsulates years of research to switch the current Proof-of-Work (PoW) Ethereum network to a Proof-of-Stake (PoS) consensus algorithm. The expected launch later this year will be phase 0 of a multiyear overhaul.
