When the compiler sees a new contract, it proceeds by processing each path item one at a time. If the order of compilation is important for your contract:
- reconsider your priorities
- repeat step 1
- read the logic inside of the
This logic may be improved over time to take advantage of parallelization or otherwise restructure. As such, one should be careful when switching compiler versions. Further, optimizers or data structures may be unstable with respect to things like renamed functions leading to changes of compilation result.
Sapio is designed to be determinism-friendly. Repeated runs of the same program should -- unless the user includes entropy -- return the same results.
However, at writing, this property is not closely audited for, so outputs should be treated as required to be stored in order to use a contract.
On the other hand, determinism means that for multi-party contracts being generated in a Replicated state machine, if all parties have the same e.g. WASM plugin, they can generate a contract definition and check that the merkle root (in this case, a bitcoin address) is the same. If it differs, either the arguments differed, someone cheated, or there was unexpected non-determinism.
