Transaction signature
This section provides developers with examples related to transaction creation and signature. It also includes sequence diagrams and step-by-step details. Please refer to this section when you want to understand details on transactions.
1. Simple transaction creation, signing and broadcast
| Actors | Description |
|---|---|
| Client | Service or GUI |
| tg-validatord | Central daemon of the solution |
| tg-vaultd | Bridge to 1 or N HSMs |
| HSM | Hardware device in charge of validating busniess rules and creating signed transaction |
Thist workflow includes DB interaction and tg-vaultd/HSM interaction as an example.
1.1 Conditions
- 2 signatures are required
- There are 2 clients
1.2 Sequences
