The limits on signature operations and amount of signature hashing done prevent possible CPU exhaustion attacks by "rogue miners" producing very expensive-to-validate two megabyte blocks. The signature hashing limit is chosen to be impossible to reach with any non-attack transaction or block, to minimize the impact on existing mining or wallet software. |
