-- Mempool Serialisation
--
-- We do not store the Tx bytes for the following reasons:
-- - A Tx serialised in this way never forms part of any hashed structure, hence
--   we do not worry about the serialisation changing and thus seeing a new
--   hash.
-- - The three principal components of this Tx already store their own bytes;
--   here we simply concatenate them. The final component, `IsValid`, is
--   just a flag and very cheap to serialise.
--------------------------------------------------------------------------------

-- | Encode to CBOR for the purposes of transmission from node to node, or from
-- wallet to node.
--
-- Note that this serialisation is neither the serialisation used on-chain
-- (where Txs are deconstructed using segwit), nor the serialisation used for
-- computing the transaction size (which omits the `IsValid` field for
-- compatibility with Mary - see 'toCBORForSizeComputation').
