 ==Context==
-The technology for [[Block Chain]] itself has been around since the beginning of the century. These simple chains allowed non-revocable commitments by creating a series of blocks that included a collection of all of the block hashes received since the last update plus the hash of that last update. The has of the current block update is calculated and published in a public place plus being added to the next update in sequence. Thus each entry onto the block chain cannot be changed as so is immutable. This feature is required to block repudiation of an action. For example if the block records the transfer of coins from one entity to another, the chain will prevent the original owner of the coin from transferring that same coin later to another entity. Thus the problem of double spending of the same coin is blocked.

 That’s all in theory, of course. As John Kenneth Galbraith put it, “A constant in the history of money is that every remedy is reliably a new source of abuse.”
