Struct sn_transfers::GENESIS_CASHNOTE

source · 
pub struct GENESIS_CASHNOTE { /* private fields */ }
Expand description

Utilities exposed Load the genesis CashNote. The genesis CashNote is the first CashNote in the network. It is created without a source transaction, as there was nothing before it.

Methods from Deref<Target = CashNote>§

source

pub fn unique_pubkey(&self) -> UniquePubkey

Return the id of this CashNote.

source

pub fn main_pubkey(&self) -> &MainPubkey

source

pub fn derived_key(&self, main_key: &MainSecretKey) -> Result<DerivedSecretKey>

Return DerivedSecretKey using MainSecretKey supplied by caller. Will return an error if the supplied MainSecretKey does not match the CashNote MainPubkey.

source

pub fn derived_pubkey(&self, main_pubkey: &MainPubkey) -> Result<UniquePubkey>

Return UniquePubkey using MainPubkey supplied by caller. Will return an error if the supplied MainPubkey does not match the CashNote MainPubkey.

source

pub fn derivation_index(&self) -> DerivationIndex

Return the derivation index that was used to derive UniquePubkey and corresponding DerivedSecretKey of a CashNote.

source

pub fn reason(&self) -> Hash

Return the reason why this CashNote was spent. Will be the default Hash (empty) if reason is none.

source

pub fn value(&self) -> Result<NanoTokens>

Return the value in NanoTokens for this CashNote.

source

pub fn hash(&self) -> Hash

Generate the hash of this CashNote

source

pub fn verify(&self, main_key: &MainSecretKey) -> Result<(), TransferError>

Verifies that this CashNote is valid.

A CashNote recipient should call this immediately upon receipt.

important: this will verify there is a matching transaction provided for each SignedSpend, although this does not check if the CashNote has been spent. For that, one must query the spentbook nodes.

Note that the spentbook nodes cannot perform this check. Only the CashNote recipient (private key holder) can.

see TransactionVerifier::verify() for a description of verifier requirements.

source

pub fn to_hex(&self) -> Result<String, TransferError>

Serialize this CashNote instance to a hex string.
