Proposed Extensions to BIP 174 for Future Extensibility



Summary:

The suggestion has been made to use Bitcoin compact uint, which is already implemented in all bitcoin applications, wallets and libraries. This would be a logical choice for PSBT consumers. For certain proprietary applications, multi-byte keys could also be used where the first byte defines the application type and the next bytes define application-specific fields. It is recommended to set proprietary bytes to 0xF0-0xFC or 0xE0-0xEF, possibly using E for Enterprise.
