January 23 - February 5 reorgs (no defense)
We call the addresses of the miners who receive the mining rewards in a reorg the “attacker” and the addresses double spent are the “victim.” The receipt timestamps are when our reorg tracker observed the blocks of a new chain become the most-work chain. “Depth” is the number of blocks that were removed from the most-work chain as a result of the reorg and “length” is the number of blocks that replaced the existing blocks in order to cause a reorg. The attacker had an expected 2.53 MH/s of hashrate to conduct one of the attacks. The overall BTG hashrate was between 2-2.5 MH/s in the days before the attack.
