After receiving a record transaction fee of $3.1 million, the AntPool mining pool has announced that it is ready to provide reimbursement.
In order to do so, representatives of the pool have temporarily frozen the funds. The sender of the fee has been requested to contact AntPool before December 10 and verify their identity through a signature using Electrum or Bitcoin Core.
In a similar incident, the administrator of the CKPool mining pool noticed that on November 30, AntPool had mined an empty block without any transactions.
This follows a previous incident on November 23, where an unknown user paid a commission of 83.65 BTC ($3.1 million) while transferring 55.77 BTC ($2.1 million). The sender of the transaction has since stated that they were a victim of hackers.
