The Beacon Chain, which can introduce proof-of-stake (PoS) to Ethereum (ETH), skilled a seven-block reorganization (reorg) on Wednesday.

A reorg can occur both by means of a malicious assault from a miner with excessive sources or just by means of community failure, equivalent to a bug, briefly leading to a duplicate model of a blockchain and bringing a probably high-level safety threat.

On May 25, seven blocks from quantity 3,887,075 to three,887,081 had been knocked out of the Beacon Chain, in accordance to information from Beacon Scan. The reorg is the longest “in years,” in response to Martin Köppelmann, CEO and co-founder of decentralized finance (DeFi) service supplier Gnosis.

Köppelmann famous that this “reveals that the present attestation technique of nodes ought to be reconsidered to hopefully end in a extra steady chain! (proposals exist already).” This implies that there’s extra work to be accomplished forward of the Merge, which is scheduled to occur someday later this 12 months.

Meanwhile, some builders have claimed that the problem is because of circumstance somewhat than one thing severe equivalent to a safety concern or a bug.

Core Ethereum developer Preston Van Loon speculated that the reorg occurred resulting from “the implementation of Proposer Boost fork,” a time period that refers to a methodology during which particular proposers are given precedence for choosing the subsequent block within the blockchain.

“We suspect that is brought on by the implementation of Proposer Boost fork alternative has not absolutely rolled out to the community,” Van Loon mentioned. “This reorg isn’t an indicator of a flawed fork alternative, however a non-trivial segmentation of up to date vs out of date consumer software program.”

Ethereum co-founder Vitalik Buterin referred to as this principle a “good hypothesis,” claiming that consumer groups had been making an attempt to grasp the scenario in order that they might suggest a repair.

Another Ethereum developer, Terence Tsao, echoed this speculation, suggesting that the reorg might need been brought on by “boosted vs. non boosted nodes in the network and the timing of a really late arriving block.”

The developer claimed to his greater than 11,000 Twitter followers that the incident was a enormous coincidence that had a mere 0.00025% chance given the circumstances. 

Meanwhile, Hugo Nguyen, founder of Bitcoin (BTC) pockets Nunchuk, criticized Ethereum builders for arguing that the incident had a very small chance as an alternative of really fixing it. “System security is only one large coincidence, proper? Deploy & pray, of us,” he mentioned on Twitter.
