Fields

parent_key_id: Identifier

Parent key id

sec_key: SecretKey

Secret key (of which public is shared)

sec_nonce: SecretKey

Secret nonce (of which public is shared) (basically a SecretKey)

output_ids: Vec<(Identifier, Option<u64>, u64)>

store my outputs + amounts between invocations Id, mmr_index (if known), amount

input_ids: Vec<(Identifier, Option<u64>, u64)>

store my inputs Id, mmr_index (if known), amount

fee: u64

store the calculated fee

participant_id: usize

keep track of the participant id
