Struct sn_transfers::MainPubkey
source · pub struct MainPubkey(pub PublicKey);
Expand description
Types used in the public API This is the MainPubkey to which tokens are send.
The MainPubkey may be published and multiple payments sent to this address by various parties.
It is useful for accepting donations, for example.
The CashNote can only be spent by the party holding the MainSecretKey that corresponds to the MainPubkey, ie the CashNote recipient.
This MainPubkey is only a client/wallet concept. It is NOT actually used in the transaction and never seen by the spentbook nodes.
The UniquePubkey used in the transaction is derived from this MainPubkey using a random derivation index, which is stored in derivation_index.
When someone wants to send tokens to this MainPubkey, they generate the id of the CashNote - the UniquePubkey - that shall hold the tokens. The UniquePubkey is generated from this MainPubkey, and only the sender will at this point know that the UniquePubkey is related to this MainPubkey. When creating the CashNote using that UniquePubkey, the sender will also include the DerivationIndex that was used to generate the UniquePubkey, so that the recipient behind the MainPubkey can also see that the UniquePubkey is related to this MainPubkey. The recipient can then use the received DerivationIndex to generate the DerivedSecretKey corresponding to that UniquePubkey, and thus unlock the value of the CashNote by using that DerivedSecretKey.

Implementations§
source§impl MainPubkey
impl MainPubkey
pub fn new(public_key: PublicKey) -> Self
sourcepub fn verify(&self, sig: &Signature, msg: &[u8]) -> bool
pub fn verify(&self, sig: &Signature, msg: &[u8]) -> bool
Verify that the signature is valid for the message.
sourcepub fn new_unique_pubkey(&self, index: &DerivationIndex) -> UniquePubkey
pub fn new_unique_pubkey(&self, index: &DerivationIndex) -> UniquePubkey
Generate a new UniquePubkey from provided DerivationIndex. This is supposed to be a unique identifier of a CashNote. A new CashNote id is generated by someone who wants to send tokens to the MainPubkey. When they create the new CashNote they will use this id, but that only works if this id was never used before.
