Don't many contracts rely on something to be verified in the real world? If I sign a contract with you to deliver 100kg of rice, and you claim I delivered wheat instead, how can an algo decide that?
- wslh 8y agoVia external sources, the blockchain cannot decide this independently and this breaks the decentralization factor. Typical solutions is to use external oracles with judges and penalty/rewards schemes. I think it is worth to take a look to MakerDAO and how they handle external oracles to create the DAI stable coin.
