It is similar to base 64 encoding, except it omits the O, 0, I, and l characters to avoid ambiguity in printed text.

Bitcoin mining normally uses special-purpose ASIC hardware, designed to compute hashes at high speed.

If there are any bitcoins left over after adding up the inputs and subtracting the outputs, the remainder is a fee paid to the miner.The cryptographic parts - scriptSig and scriptPubKey - are more complex and will be discussed later.Anyone who has the public key, the message, and the signature can do some simple elliptic curve arithmetic to verify that the signature is valid.But there is I always one question for which I can never ferret out the answer.

Bitcoin mixes big-endian and little-endian values, which makes things confusing.
