Aztec 3 Protocol Notes and Nullifiers On this page
Private State Fragmented State (Set) Talk about how a state's 'value' can be fragmented across many notes. Discuss how states can be updated in such cases. Discuss how custom notes and nullifiers are possible Give examples that aren't just 'summing values'. Give examples of how custom notes gives builders flexibility, and enables compliant token designs. Give example Noir syntaxDiscuss the interface that will be expected of notes, by our Noir Contract stdlib state variable types Discuss how decrypting, recomputing the note_hash, and recomputing the nullifier works. Solid state (Singleton) Talk about a state which always inhabits one and only one note. Talk about initialisation nullifiers. Custom Nullifiers Talk about how we can have nullifier keys, which are siloed to one contract. Talk about other examples of how Nullifiers are usedzk-nullifiers signalling, like semaphore see nice blog post which suggests other kinds of nullifier Public Notes Talk about how public state can also be stored in notes in the private data tree. Talk about the design challenges we've encountered (given that such notes don't need to be trial-decrypted becuase they're public!), and how we're solving those. Notes containing complex types Talk about how we can 'squish' complex types into Notes.
