a reorganization of blocks observed on the network

The Beacon chain, which will introduce proof-of-stake (PoS) at Ethereum (ETH), underwent a seven-block renewal on Wednesday.

A reorganization can occur either as a result of a malicious attack by a high-resource miner, or simply as a result of a network failure, such as an error that temporarily results in a duplicate version of a blockchain and presents a potentially high security risk.

On May 25, the seven blocks numbered 3,887,075 to 3,887,081 were eliminated from the beacon chain, according to Beacon Scan data. This reorganization is the longest “this year”, according to Martin KöppelmannCEO and co-founder of decentralized financial services provider (DeFi). Gnosis.

Köppelmann noted that this “shows that the current node certification strategy should be reconsidered in order to hopefully lead to a more stable chain! (Proposals already exist)”. This means that there is still work to be done before the merger, which is expected to take place later this year.

On the other hand, some developers have argued that the problem is due to circumstances rather than a more serious event such as a security issue or an error.

Preston Van Loondeveloper of Core Ethereum, speculated that the reorganization was due to the “implementation of Suggest Boost Fork“, a term that refers to a method in which specific proposers are prioritized to select the next block in the blockchain.

“We suspect that this has happened due to the implementation of Suggest Boost Fork has not been fully implemented for the network, “Van Loon said.” This reorganization is not an indicator of incorrect fork selection, but a segmentation of updated client software from those that do not. is it not.”

Co-founder of Ethereum, Vitalik Buterincalled the theory a “good guess” and said client teams were trying to understand the situation so they could come up with a solution.

Another Ethereum developer, Terence Tsaohave echoes of this hypothesis, suggesting that the reorganization may be caused by “amplified and non-amplified nodes in the network and the timing of a block arriving very late”.

The developer claimed to his more than 11,000 Twitter followers that the incident was a huge coincidence with a probability of only 0.00025% given the circumstances.

In the meantime Hugo Nguyenfounder of the Bitcoin (BTC) wallet nunchuck, criticized the Ethereum developers for claiming that the incident had a very low probability of occurring instead of trying to solve the problem. “System security is not just a coincidence. Post and pray, friends,” he said on Twitter.
