However, if the hash rate distribution across the bitcoin network is anything to go by (and it is) then most miners are opting to join a pool.
Tampering with the Delivery of Blocks and Transactions in Bitcoin Arthur Gervais. a nonce value that,.Note that once the method is widely disseminated and adopted by other miners, the computational power imbalance straightens out again, and the difficulty of the hashing problem can be scaled accordingly.In this case, it is easy to see that a first-preimage attack on a hash function (or perhaps a slightly weaker) attack means that this hashing problem can be solved much more quickly.Primecoin: Cryptocurrency with Prime Number Proof-of-Work. regarding the distribution of prime numbers,.Leveraging Blockchain Technology to Protect the National Security Industrial Base. with a density and distribution of sensors. a nonce into a SHA-256 hash.

The short story is that the thrust of my argument remains the same, but the details of a hypothetical attack against the cryptographic function are a bit more complicated—a simple chosen-prefix collision attack will not be sufficient.
