Systems and methods are provided for utilizing a digital coin. A bit string is received. The number of bits in the bit string represents a coin value of the digital coin. The individual bit values of the bits of the bit string are used to determine an identity of the digital coin. The identity of the digital coin is validated by a node of an authentication hierarchy. The validation includes comparing bit values of at least a portion of the bits of the bit string to bit values of corresponding bits of known bit strings that represent known issued digital coins. The validation also includes checking that a matching known issued digital coin was not previously redeemed. A digital coin can also be split into multiple digital coins that are each a continuous sequence of bits of the bit string of the original digital coin.
