With Account control, any account can be restricted to only issuing phased transactions subject to a specific voting model. This enables interesting use cases like:
- Multi-signature, so that more than one key is required to authorize a transaction.
- Tagging, so that an account tagged as e.g. "savings" cannot, for example, send tokens.
- Escrow, so that a locked account cannot transfer assets, aliases, etc. except when some specific circumstances are met.
