Struct AggregatedNonce 

pub struct AggregatedNonce(/* private fields */);

Musig aggregated nonce computed by aggregating all individual public nonces

Implementations

impl AggregatedNonce

pub fn new(nonces: &[&PublicNonce]) -> AggregatedNonce

Combine received public nonces into a single aggregated nonce

This is useful to reduce the communication between signers, because instead of everyone sending nonces to everyone else, there can be one party receiving all nonces, combining the nonces with this function and then sending only the combined nonce back to the signers.

Example:

// The session id must be sampled at random. Read documentation for more details.

let msg = b"Public message we want to sign!!";

let session_secrand1 = SessionSecretRand::from_rng(&mut rand::rng());
let (_sec_nonce1, pub_nonce1) = key_agg_cache.nonce_gen(session_secrand1, pub_key1, msg, None);

// Signer two does the same: Possibly on a different device
let session_secrand2 = SessionSecretRand::from_rng(&mut rand::rng());
let (_sec_nonce2, pub_nonce2) = key_agg_cache.nonce_gen(session_secrand2, pub_key2, msg, None);

let aggnonce = AggregatedNonce::new(&[&pub_nonce1, &pub_nonce2]);

Panics

Panics if an empty slice of nonces is provided.

pub fn serialize(&self) -> [u8; 66]

Serialize a AggregatedNonce into a 66 bytes array.

pub fn from_byte_array(data: &[u8; 66]) -> Result<AggregatedNonce, ParseError>

Deserialize a AggregatedNonce from byte slice

Errors:

• MalformedArg: If the byte slice is 66 bytes, but the AggregatedNonce is invalid

pub fn as_ptr(&self) -> *const MusigAggNonce

Get a const pointer to the inner AggregatedNonce

pub fn as_mut_ptr(&mut self) -> *mut MusigAggNonce

Get a mut pointer to the inner AggregatedNonce
