Medalla, the final Ethereum (ETH) 2.0 testnet before Phase 0 (the Beacon Chain) of ETH 2.0, has been running “reliably” for at least two days now, as Ethereum co-founder Vitalik Buterin said, and is currently well above the minimum number of validators that are required to be actively participating for the chain to finalize.
At pixel time, per Beaconcha.in, the participation is around 76%. For the last two days, it moved between the higher end of 60% and up to 81%, mostly staying in the mid-70% range. There were a couple of short, sudden drops, for example epoch 4837, which passed several hours ago, and saw an immediate drop to 1% but quickly recovered.
As previously reported, Prysm coder Terence Tsao wrote that the chain requires at least 66% of validators to be actively validating for the chain to finalize.
Buterin noted the higher numbers, stating that the testnet “seems to be reliably at >75% participation”, and his observation appears to remain largely correct.
