    Bitcoin mining rainbow table question : Bitcoin

    Bitcoin mining rainbow table question Since much of the computational overhead in mining bitcoins comes from generating hashes (verifying them is far faster) starting with the required number of zeros and this process is done each time a new block is received, would it not be more efficient to use rainbow tables? A cryptographic hash function (CHF) is a hash function that is suitable for use in cryptography.It is a mathematical algorithm that maps data of arbitrary size (often called the "message") to a bit string of a fixed size (the "hash value", "hash", or "message digest") and is a one-way function, that is, a function which is practically infeasible to invert. There is no one size fits all for exchanges. Each user has unique needs when buying cryptocurrency. Our Bitcoin and cryptocurrency exchange reviews detail each exchange's supported countries, payment methods accepted, fees, privacy, limits, liquidity, reputation, speed (delivery of coins), customer support, and any past issues.
