The term smart contract is over 20 years old, but we've only actually seen them implemented and used in the wild in the last few years. The trustless nature of a block n explains that we thought these up 20 years ago, and we only managed just now to build something that makes them useful. And it's really like ethereum, that popularized term, because it's this kind they branded themselves from the beginning as a smart contract platform. But don't you think, i mean, at least maybe we should talk a little bit the history of this smart contract concept?
