Marathon Digital, a Bitcoin mining company, has acknowledged mining an invalid Bitcoin block as part of an experimental initiative aimed at enhancing its operational efficiency. This revelation was made in a statement released on September 27, with the company stressing that the experiment was conducted using a small portion of its computing power and was not intended to make any alterations to the Bitcoin network.
Marathon was emphatic that this experiment did not constitute an attempt to modify Bitcoin Core, the predominant software used for interacting with the Bitcoin network and operating nodes. Furthermore, they promptly rectified the error as soon as they became aware of the invalid block. It's important to note that the vulnerability originated within Marathon's internal development environment and was unrelated to its Bitcoin production pool or Bitcoin Core.
The incident occurred on September 26, specifically at block 809,478, according to data from Mempool.space. Some Bitcoin developers and BitMEX Research have attributed the occurrence of invalid blocks to a "transaction ordering issue." One Bitcoin developer known as "mononaut" proposed that Marathon's error resulted from reordering transactions based on ascending absolute fees.
Marathon firmly stated that, despite this unintentional incident, the Bitcoin network continues to function precisely as designed. They highlighted the robust security of the Bitcoin network, which promptly rejected and rectified this anomaly. Following this revelation, Marathon's (MARA) shares experienced a 2.91% decline to $8.01 during the opening bell on September 27, according to Google Finance.
