type t

A proving context. Stores information about the commitment values and is used for the binding_sig. A context should created with init, passed to spend_proof for all inputs and output_proof for all outputs, passed to make_binding_sig and finally freed with free. *

type ar

Randomness to randomise the signature key. *

val with_proving_ctx : (t -> 'a) -> 'a
val ar_random : unit -> ar
val spend_sig : Spending_key.t -> ar -> CV.t -> Nullifier.t -> UTXO.rk -> UTXO.spend_proof -> string -> UTXO.spend_sig

String is the anti-replay. *

val spend_proof : t -> Viewing_key.t -> Spending_key.t -> Viewing_key.address -> Rcm.t -> ar -> amount:int64 -> root:Hash.t -> witness:Stdlib.Bytes.t -> CV.t * UTXO.rk * UTXO.spend_proof
val output_proof : t -> DH.esk -> Viewing_key.address -> Rcm.t -> amount:int64 -> CV.t * UTXO.output_proof
val make_binding_sig : t -> UTXO.input list -> UTXO.output list -> balance:int64 -> string -> UTXO.binding_sig
