Struct exonum_btc_anchoring::api::Payload

pub struct Payload {
    pub block_height: Height,
    pub block_hash: Hash,
    pub prev_tx_chain: Option<TxId>,
}

Anchoring transaction payload.

Data layout in OP_RETURN script for Payload v.1:

| Position in bytes | Description | |------------------- |---------------------------------------------- | | 0..6 | ASCII-encoded prefix EXONUM | | 6 | Version byte, currently is 1 | | 7 | Payload kind: (0 is regular, 1 is recover) | | 8..16 | Block height | | 16..48 | Block hash | | 48..80 (Optionally) | Txid of previous tx chain (only for recover kind) |

In this way the length of regular payload is 48, and for recover is 80.

Fields

block_height: Height

Anchored block height

block_hash: Hash

Anchored block hash

prev_tx_chain: Option<TxId>

Txid of previous transactions chain if it has been lost.
