Would an optimization proof-of-work downside the place the entity with the bottom hash wins have any safety weak spot or different drawback?


Usually, one might predict the “common” hash that’s profitable.

When a miner is fortunate sufficient to discover a hash that’s unusually higher than regular, it might hold that block to itself, and get a headstart mining the following block, and the following block.

When a competing block is launched by a competing miner, the unique miner can launch its beforehand secret block with an exceptionally low hash, which is thought to be a assured “winner”.

This is able to invalid the work of different miners, and implement the miner’s headstart on future work, giving it an unfair benefit and larger management over the blockchain.
