Transaction lifecycle

Smart contracts interact with transaction during transaction lifecycle as described in the following diagram:

Transaction lifecycle steps.

1. Client signs transaction and sends it to API endpoint /api/events/add/event={encoded transaction}

2. Transaction is received by node.

3. Blockchain node checks that the state of transaction is consistent with the blockchain state and transaction is signed properly. If not - rejects transaction.

4. Node checks if there is a smart contract associated with space specified in space transaction field. If there is no such smart contract - transaction is approved.

5. In the case smart contract is found, node executes confirm method. If the result is true - transaction is approved, otherwise rejected.
