The 'coin part' already has a name and it's not a new innovation. Large part of financial innovation in the last century is based on the idea that is now called coin. It's called derivative. If you have something valuable that can be traded, it can be made into derivative and traded in existing markets. Practically anything, physical things, electricity, indexes, future events or prices, insurances, storage capacity, contracts, mortgages, price differences, ... only the sky is the limit. New technological solutions can hopefully expand this existing trend but it's already very efficient. |
Nitpick, though an interesting one. What you are describing is "securitization" more so than a derivative.
There are essentially five things you can do in finance: move cash flows in time (e.g. lending), move them between holders (e.g. buying and selling shares), chop them up into securities (e.g. an IPO), assemble them into portfolios (e.g. CDOs) and write derivatives against them (e.g. insurance). The newcomer is securitization. It first arose in 900 CE in the Song Dynasty in common memory through the 1602 Dutch East India Company public share offering.
ICOs look like a combination of the first (buy a token now, redeem it for services later) and third (they look like shares, though what exactly we're chopping up continues to evade me). Bitcoin itself looks like number two minus any cash flows. Or, more simply, gambling.
