Bitcoin mining firm Marathon Digital experienced an incident where it mined an invalid Bitcoin block during an experiment aimed at optimizing its operations. The company confirmed that this experiment was not an attempt to alter Bitcoin Core, the leading software used to connect to the Bitcoin network. The bug that caused the invalid block originated from Marathon’s internal development environment and was unrelated to its Bitcoin production pool or Bitcoin Core. The error was promptly corrected once identified. Bitcoin developers and BitMEX Research attributed the invalid block to a transaction ordering issue, specifically the sorting of transactions based on ascending absolute fees. Bitcoin analyst Dylan LeClair suggested that Marathon should have conducted this experiment on a testnet before attempting it on Bitcoin’s mainnet. Marathon acknowledged that Bitcoin functioned as designed by rejecting and rectifying the anomaly, emphasizing the robust security of the Bitcoin network.
Despite not receiving an immediate response, Cointelegraph reached out to Marathon for comment on the incident. In response to the incident, Marathon’s share price experienced a decline of 2.91% to $8.01. This incident highlights the importance of conducting thorough testing and experimentation on a separate testnet before implementing changes on the mainnet. Marathon’s intention was to optimize its operations, but the bug resulted in the mining of an invalid block. Bitcoin developers and experts play a crucial role in identifying and rectifying such issues to ensure the integrity and security of the Bitcoin network. It is noteworthy that Bitcoin ultimately functioned as designed and rejected the invalid block, illustrating the robustness and reliability of the network.
