Emitted Txn

EmitDetails

Object

Object

Yes

Contains details about the emission. This includes the generation of the emission, the burden of the emission, the callback address, the hash of the hook that emitted the transaction, the nonce of the emission, and the ID of the parent transaction.

TransactionType

String

UInt16

Yes

The type of the transaction that was emitted.

Account

String

Account

Yes

The account that emitted the transaction.

Fee

String

Amount

Yes

The fee paid for the transaction.

Sequence

Number

UInt32

Yes

The sequence number of the transaction.

SigningPubKey

String

Blob

Yes

The public key that signs the transaction.

EmitGeneration

Number

UInt32

Yes

This field keeps track of a chain of emitted transactions that in turn cause other transactions to be emitted.

EmitBurden

String

UInt64

Yes

This field is a heuristic for detecting forkbombs. Fees are based on burden and will increase exponentially when a chain reaction is started to prevent the network becoming overun by self-reinforcing emitted transactions.

EmitParentTxnID

String

Hash256

Yes

The Hook Execution that emitted the transaction is connected to the Originating Transaction. Therefore this field is always required for the efficient tracing of behaviour.

EmitNonce

String

Hash256

Yes

Emitted Transactions would be identical with the same fields and therefore have identical transaction hashes if a nonce were not used. However every node on the network needs to agree on the nonce, so a special Hook API to produce a deterministic nonce is made available.

EmitCallback

String

AccountID

No

This field is used by xahld when it needs to intitate a callback, such that it knows which Hook and account to initate the callback on. Callbacks happen when an emitted transaction is accepted into a ledger.

EmitHookHash

String

Hash256

Yes

The SHA512H of the Hook at the time it was executed.
