FIX messages for blockchain - FIXChain

A valid tag=value FIX message has a checksum computed.  So it's possible to detect if a message was corrupted over the wire. So FIX is used to calculating a value based upon the payload of a message.

FIX is used to chaining messages together - think of tags 17 and 19 as a simple example.

Alongside the checksum, why not add in a hash of the FIX message to the FIX message itself and you have a way to implement a distributed ledger messaging mechanism.

Let's call it FIXChain.

I'll return to this in future...
