block_unpacker

Block unpacker module

The block unpacker module accepts block bodies and unpacks them into transactions

Configuration

The following is the default configuration - if the defaults are OK, everything except the section header can be left out.

[module.block-unpacker]

# Message topics
subscribe-topic = "cardano.block.body"
publish-topic = "cardano.txs"

Messages

The block unpacker subscribes for BlockBodyMessages on cardano.block.body (see the Upstream Chain Fetcher module for details). It unpacks this into transactions, which it publishes as a single RawTxsMessage on cardano.txs, containing the block information and an ordered vector of raw transaction CBOR. This ensure the transactions are kept in order.

pub struct RawTxsMessage {
    /// Block info
    pub block: BlockInfo,

    /// Raw Data for each transaction
    pub txs: Vec<Vec<u8>>,
}
