What if the two parties use different smart contract systems? • ETD markets are often accessed via a number of brokers and “long chains” are a common feature of ETD markets – how may smart contracts work harmoniously along the entire chain? • Some of these contracts (e.g. inflation swaps) might last 50 years – technology changes a lot in 50 years… • In the absence of a single industry standard language or platform for Smart Contracts, is it too early to standardise using Smart Contracts?
