Martin Koppelmann, co-founder of Gnosis, picked up on the reorganization of 7 blockchains on Ethereum’s Beacon network. He noted the “current attestation strategy of nodes should be reconsidered to hopefully result in a more stable chain.”
While most people have been focusing on Ethereum’s switch to Proof of Stake, Beacon has undergone reorganizations over 7 blockains. This reorg is a chain split where nodes receive blocks from a new chain from the existence of the old one. The reorg in Ethereum’s case, took place over block height 3,887,075 to 3,887,081.
“The Ethereum beacon chain experienced a 7-block deep reorg —2.5h ago,” Köppelmann said. “This shows that the current attestation strategy of nodes should be reconsidered to hopefully result in a more stable chain… (proposals already exist).”
“This, unfortunately, shows that the analysis by [Georgios Konstantopoulos] and [Vitalik Buterin] here was too optimistic when the article claimed reorg stability will improve in PoS over PoW. We have not seen 7 block reorgs on Ethereum mainnet in years… At this point, it is unclear whether the reorg we saw was caused by an attack or just unfortunate network conditions.”
Koppelman later retracted the statement as a poor response led him to regret what he said. However, in response to this, Vitalik Buterin, Ethereum co-founder said “Truth-seeking is more important than ‘not giving the wrong people rhetorical ammunition’ or whatever.”
“In this case, client teams have been scrambling to understand the situation so they can figure out what to fix for the last couple of hours — Already some good hypotheses,” he said in response to Ethereum developer, Preston Vanloon’s statement: “We suspect this is caused by the implementation of Proposer Boost fork choice has not fully rolled out to the network. This reorg is not an indicator of a flawed fork choice, but a non-trivial segmentation of updated vs out of date client software.”
Both Vanloon and Buterin suggest that The Merge could be implemented in August even though Buterin is still cautioned by the “risk of problems” and “delays.”
