Financial instruments can be implemented on the Bitcoin block chain through protocols such as Bitshares, Counterparty, and Omni. However, these have mostly gone out of favor with companies now preferring to implement financial instruments based on Ethereum.
Solidus and SwiftCoin are scams so it doesn't matter how they work.
Solidus is an easy scam to spot, and was aware it was one after reading about it for a whole 2mns. But I thought maybe the protocols/tech behind it , or however you state that, might be legit for a non-scam smart bond..like the one UBS was trying to create.
I was hoping there was some advancement with S.C's in this area, but I see that's likely not been happening. I get why they are going to Ethereum, and knew they were, but that's mostly bs no? Sure it provides the platform to build, but that's only half the battle, the S.C. functioning as a game changer is the other half right. DeFi is a good example of how this is not reality yet. As well as this not being a reality yet-
