We discussed this issue with @giacomozucco and came to the following proposal:
- Contracts should be allowed to issue assets to an UTXO outside of the commitment tx
- The moment of the contract commitment is the moment of the asset issuance. Assets are assigned at this point to the
issue_utxo - Commitment tx should be added as a field into the contract header, but it can participate in the commitment itself (i.e. is not a part of the contract hash).
- Since (according to #87)
asset_id"commits" to the contract commitment tx it serves as a protection from multiple contract deployments, since each contract deployment will result in a different set of the issuedasset_ids
from spec.
