TransactionAck¶
Purpose¶
A TransactionAck is
a potentially instant notification for a received transaction
notifying about the batch number of the worker
and when this batch was started according to the worker's local time.
Structure¶
| Field | Type | Description |
|---|---|---|
hash |
bytes | the hash of the transaction request acknowledged |
batch_number |
natural number | the batch number assigned |
batch_start |
wall clock time | the wall clock time of the worker when opening the batch |
collector_id |
ExternalIdentity | the ɪᴅ of the worker engine that collected the transaction |
| signature | bytes | the signature of the collecting worker engine over the above |
Note¶
We cannot make use of a TxFingerprint of the transaction, because there might be a slight delay between message reception and assignation of transaction number for the acknowledged transaction candidate that is contained in a request. Also, there might be several requests for the same transaction candidate even if this is the not the standard scenario.
