Two Bitcoin blocks were mined with the same nonce, what does this mean?
On January 31, 2025, two Bitcoin blocks were mined with the same “nonce,” a number that miners adjust to find a valid hash. This occurrence is extremely rare and has only happened 105 times in the history of Bitcoin. The “nonce” is a 32-bit number used in Bitcoin mining to secure the network and promote decentralization. Although the “nonce” coincidence does not affect the security or operation of the network, it is a statistically improbable and surprising event. This event highlights the probabilistic nature of Bitcoin mining and how, despite the huge possible combinations, rare coincidences can occur.
