Do Hashrate Rental Platforms Guarantee the Successful Mining of a Specific Block?

No, hashrate rental platforms typically guarantee the delivery of a specified amount of computational power (hashrate) for a set duration. They do not guarantee the discovery of a block or the success of a mining operation.

Mining remains a probabilistic process. The renter pays for the effort (hashrate), not the result (block reward).

The attacker's success in a 51% attack depends on their ability to maintain the majority hashrate long enough to outpace the honest network.
