A bitcoin mining pool named F2Pool created an invalid block on April 1, 2023, at height 783426, according to BitMEX Research, a cryptocurrency derivatives exchange. They did not specify why, though, and the situation is currently being looked into.
According to BitMEX Research, the F2Pool Mining Pool Generated an Invalid Bitcoin Block
The bitcoin height 783426 generated two blocks, according to ForkMonitor, a node monitoring program sponsored by BitMEX. The invalid block has a hash of 00000000000000000002ec935e245f8ae70fc68cc828f05bf4cfa002668599e4.
BitMEX announced this with a tweet.
If a bitcoin block follows the protocol specifications, it is regarded as valid. BitMEX believes that improper signature operations led to the faulty block. While they tried to explain the oddity, the exchange stated that they were still looking into it.
About ForkMonitor
ForkMonitor was introduced by BitMEX in 2018 to track hard and soft forks on the Bitcoin network. 13 nodes of Bitcoin, including those of Bitcoin Cash, and its hard forks are connected to ForkMonitor. Moreover, the technique is used to find accidental consensus problems.
About Invalid Bitcoin Blocks
When the same funds are spent twice, this could invalidate a block that was mined in bitcoin. One transaction would be accepted by the network, while the other is rejected as invalid. Another possible explanation is when a miner attempts to use bitcoin that they do not possess. As the user doesn’t have enough money in their wallet to complete the transaction, the network will reject it.
A time-locked transaction that failed script validation and whose lock time was not met is also regarded as invalid. According to the protocol level, new Bitcoin blocks are released every 10 minutes or so.
