What property do you want to gain from that? Blockchains are:
* A chain of blocks. Usually where each block sign/content-address its
* A proof of work algorithm for producing a new block
The nice property is that the chain allows you to go back in time and ask
about historical data, while providing integrity: the chain opposes
historic rewrites as time passes. They have other nice properties as well,
but I must admit I fail to see where those properties fit into the idea of
supervision. For (loose) consensus it may work, but there are other
algorithms which tend to fare better for this situation, because a typical
Erlang cluster doesn't require the integrity properties of the blockchain.
Note: I don't dismiss the idea, but I fail to see where it is applicable.
Can you possibly elaborate?
