There are only two ways to use a blockchain-based currency in OT:
1. Trust an issuer to hold the coins, and then he issues the corresponding units inside OT. Markm's OT server is doing this now. This is the same as if he was holding gold, or dollars, etc.
2. Eliminate the issuer by putting the coins into a multi-sig voting pool. We are working on this now and should have the code ready soon. Note that this will only work with blockchains that support multi-sig.
Can miners be issuers? Or mining pools would act as issuers? Or is this more like, somebody sets up an issuer that acts like a local exchanger, you send your mined coins to them, and they send you the OT tradeable units. You are trusting them to be your reserve bank.
With #2, once you do this, can you then trade and perform transactions with the coins in the voting pool, or do you still need to convert them into tradeable units?
Also for #2, does this require a bitcoin-based blockchain, or does it only require a multi-signature interface that you could have a different type of blockchain behind?
Last question for now - so is there one OTX P2P network, that everyone using OTX will connect to? To facilitate trades between assets I might define, and assets somebody else might define.
Sorry if too many questions. But OT is very interesting to me and I have some ideas for something I want to build.
