The Ropsten Proof-Of-Stake ‘Test Merge’ on Ethereum Has Gone Live
Developers have activated the merging on the Ropsten test network in anticipation for the Ethereum merge later this year.
After being announced on June 3, the merger took place on Wednesday afternoon.
Ropsten’s proof-of-work and proof-of-stake beacon chains were unified by integrating their scripts into one
Today’s merging is crucial for ensuring that client software that uses Ethereum nodes runs smoothly. Lighthouse, Lodestar, Prysm, Teku, Besu, Erigon, go-ethereum (geth), and Nethermind were among the client software teams involved in the merger.
The Ethereum mainnet merging, which has yet to be scheduled, will follow a similar pattern later this year. In fact, today’s event was meant to be a significant warm-up for the mainnet merging, which will see Ethereum switch from proof-of-work to proof-of-stake consensus.
“I mean of course, the merge working well for 6 hours isn’t evidence of complete success,” said Vitalik Buterin, co-founder of Ethereum, in the livestream earlier today. “There are all of these kind of longer term issues around MEV and staking centralization and protection against DOS attacks and things that could potentially bite us 3 weeks after the merge instead of 2 minutes during the process.”
In April, ten shadow forks on the main network and another merge on Kiln, a testnet, were conducted.
The complexity of today’s test is determined using a criterion known as terminal total difficulty. Once this degree of block difficulty is attained on the proof of work version, the merging is considered active. By artificially collecting hashrate, the proof-of-work version of Ropsten crossed a pre-set 50 quadrillion measure to protect the merging from any malicious activity.
Node operators had to manually configure their clients to override the Ropsten Terminal Total Difficulty for both the proof-of-stake version and proof-of-stake clients before the merging was activated.
