dude: it's the first time in human history where third parties are neither required for contracts to be ATOMICALLY binding. i'm not sure if you grasp the full significance of that.
prior to blockchain and hashgraph and so on the only way to guarantee that a contract was honoured is to (a) trust each party in the contract and (b) if there is a dispute trust a THIRD PARTY.
entire power structures have built up over millenia based around that and THIS IS THE FIRST TIME THE POWER TO NEGOTIATE CONTRACTS IS TRULY DECENTRALISED.
Well, sort of. The actual exchange of currency doesn't involve a third party, and in the case of e.g. Ethereum there's a lot of interesting stuff you can do within the network. But for most real-world contracts you need information from outside the network about whether one party actually fulfilled its obligations, and then you're back to the messy realities of human trust.
