This is an ECDSA signature representation in compact form. It is nonstandard and defined by the libsecp256k1 library.

Used in: stacks.signer.v1.Signed

• optional Uint256 lower_bits = 1

  These are the first 256-bits of the 64 byte signature part, so bits 0-255.

• optional Uint256 upper_bits = 2

  These are the last 256-bits of the 64 byte signature part, so bits 256-511.

Represents a point on the secp256k1 elliptic curve. A Point is either a public key, like the crypto.PublicKey type, or the point at infinity.

Used in: wsts.BadPrivateShare, wsts.PolyCommitment, wsts.ProofIdentifier, wsts.PublicNonce, wsts.SchnorrProof, wsts.SignerState, wsts.TupleProof

• optional Uint256 x_coordinate = 1

  The x-coordinate of the point.

• bool parity_is_odd = 2

  Represents the parity bit of the point. True means the parity is odd, while false means the parity is even.

/ Represents a public key type for the secp256k1 elliptic curve.

Used in: stacks.signer.v1.RotateKeys, stacks.signer.v1.Signed, stacks.signer.v1.StacksTransactionSignRequest, stacks.signer.v1.WstsMessage

• optional Uint256 x_only_public_key = 1

  The x-coordinate of the public key.

• bool parity_is_odd = 2

  Represents the parity bit of the public key. True means the parity is odd, while false means the parity is even.

This is a recoverable signature representation. It is nonstandard and defined by the libsecp256k1 library.

Used in: stacks.signer.v1.StacksTransactionSignature

• optional Uint256 lower_bits = 1

  These are the first 256-bits of the 64 byte signature part, so bits 0-255.

• optional Uint256 upper_bits = 2

  These are the last 256-bits of the 64 byte signature part, so bits 256-511.

• int32 recovery_id = 3

  A tag used for recovering the public key from a compact signature. It must be one of the values 0-3.

Scalar maps to a nonnegative number less than the order of the secp256k1 curve.

Used in: wsts.Polynomial, wsts.PrivateKeyShare, wsts.PrivateNonce, wsts.ProofIdentifier, wsts.SchnorrProof, wsts.SignatureShare

• optional Uint256 value = 1

A message type only used for values of maps when a set is desired. The "Zst" in the end stands for Zero-sized type, because this will be turned into a zero-sized type in Rust.

Used in: wsts.BadPublicShares, wsts.MissingPrivateShares, wsts.MissingPublicShares

/ A type representing a 256-bit integer.

Used in: bitcoin.BitcoinBlockHash, bitcoin.BitcoinTxid, EcdsaSignature, Point, PublicKey, RecoverableSignature, Scalar, wsts.MerkleRoot, stacks.StacksBlockId, stacks.StacksTxid, stacks.signer.v1.WstsMessage

• fixed64 bits_part0 = 1

  These are the 64 bits of the 256-bit integer from bits 0-63.

• fixed64 bits_part1 = 2

  These are the 64 bits of the 256-bit integer from bits 64-127.

• fixed64 bits_part2 = 3

  These are the 64 bits of the 256-bit integer from bits 128-191.

• fixed64 bits_part3 = 4

  These are the 64 bits of the 256-bit integer from bits 192-255.
