Ethereum’s oldest Proof of Work testnet has successfully upgraded to full Proof of Stake following some delay due to miners reducing the hashrate.
The Beacon chain was launched earlier this month with the terminal to total difficulty (TTD) for the full upgrade just crossed.
That means Ropsten now no longer has miners, but only stakers, about 101,000 validators that have put down 3 million testnet eth.
“Now blocks are being built by Proof of Stake validators,” Danny Ryan, the eth2.0 coordinator, said.
This is the first full upgrade of a long running testnet, with it seemingly going smoothly so far.
Another two testnets are to be upgraded before the live merge expected sometime in September or October.
At which point ethereum will no longer have miners, or a hashrate, but only stakers which will receive about 10x less in block rewards than current miners, reducing inflation with eth set to become a lot rarer.
All seems to be going smoothly so far. One crucial measure is nodes are talking to each other and agree.
All are in sync at this point, so there’s no hiccup, there’s no problem, no rogue blocks which is a good omen for a successful live merge.
