Builder Signature Key trait with minimal requirements

Required Associated Types

type BuilderPrivateKey: PrivateSignatureKey

The type of the keys builder would use to sign its messages

type BuilderSignature: Send + Sync + Sized + Clone + Debug + Eq + Serialize + for<'a> Deserialize<'a> + Hash

The type of the signature builder would use to sign its messages

type SignError: Error + Send + Sync

Type of error that can occur when signing data

Required Methods

fn validate_builder_signature( &self, signature: &Self::BuilderSignature, data: &[u8], ) -> bool

validate the message with the builder’s public key

fn sign_builder_message( private_key: &Self::BuilderPrivateKey, data: &[u8], ) -> Result<Self::BuilderSignature, Self::SignError>

sign the message with the builder’s private key

Errors

If unable to sign the data with the key

fn generated_from_seed_indexed( seed: [u8; 32], index: u64, ) -> (Self, Self::BuilderPrivateKey)

Generate a new key pair

Provided Methods

Errors

If unable to sign the data with the key

fn sign_bundle<TYPES: NodeType>( private_key: &Self::BuilderPrivateKey, transactions: &[TYPES::Transaction], ) -> Result<Self::BuilderSignature, Self::SignError>

sign transactions (marketplace version)

Errors

If unable to sign the data with the key

fn sign_block_info( private_key: &Self::BuilderPrivateKey, block_size: u64, fee_amount: u64, payload_commitment: &BuilderCommitment, ) -> Result<Self::BuilderSignature, Self::SignError>

sign information about offered block

Errors
