1) You might put a diagram or schematic in to illustrate a Bitcoin Asset and/or a Bitcoin Gold Asset
2) Similarly, show us an example of a wallet tied to, say, a 1/10th oz gold coin (this is a common small sized bullion coin)
Thanks OROBTC, that's a good idea. Is a high-level view sufficient - where Bitcoin is treated as a black box - or do you think readers would benefit from a bit more detail? I think dropping down to OP_RETURN and transaction outputs might be too much.
