Published Data Format
The "Effects" of a transaction are the collection of state changes and metadata that resulted from executing a transaction. These include:
| Field | Type | Description |
|---|---|---|
revertCode | RevertCode | Indicates the reason for reverting in public application logic. 0 indicates success. |
note_hashes | Tuple<Fr, typeof MAX_NEW_NOTE_HASHES_PER_TX> | The note hashes to be inserted into the note hash tree. |
nullifiers | Tuple<Fr, typeof MAX_NEW_NULLIFIERS_PER_TX> | The nullifiers to be inserted into the nullifier tree. |
l2_to_l2_msgs | Tuple<Fr, typeof MAX_NEW_L2_TO_L1_MSGS_PER_TX> | The L2 to L1 messages to be inserted into the messagebox on L1. |
public_data_writes | Tuple<PublicDataWrite, typeof MAX_PUBLIC_DATA_UPDATE_REQUESTS_PER_TX> | Public data writes to be inserted into the public data tree |
encrypted_logs | TxL2Logs | Buffers containing the emitted encrypted logs. |
unencrypted_logs | TxL2Logs | Buffers containing the emitted unencrypted logs. |
Each can have several transactions. Thus, an block is presently encoded as:
| byte start | num bytes | name |
|---|---|---|
| 0x0 | 0x4 | len(newL1ToL2Msgs) (denoted a) |
| 0x4 | a * 0x20 | newL1ToL2Msgs |
| 0x4 + a * 0x20 = tx0Start | 0x4 | len(numTxs) (denoted t) |
