Struct exonum_btc_anchoring::btc::Payload

pub struct Payload {
    pub block_height: Height,
    pub block_hash: Hash,
    pub prev_tx_chain: Option<Sha256d>,
}

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<Sha256d>

Txid of previous transactions chain if it has been lost.
