MuSig2 key aggregation context

Fields

pubkeys: Vec<[u8; 33]>

Individual public keys (33 bytes compressed)

aggregated_pubkey: [u8; 33]

Aggregated public key (33 bytes compressed)

xonly_pubkey: [u8; 32]

X-only aggregated public key (32 bytes)

coefficients: Vec<[u8; 32]>

Key aggregation coefficients

parity: bool

Whether the aggregated key needed negation

Implementations

impl MuSigKeyAgg

pub fn new(pubkeys: Vec<[u8; 33]>) -> Result<Self>
