Protocol: Addresses & Keys

[iAmMichaelConnor]

A list of things to consider:

• Addresses & Keys
  • Requirements
  • Addresses
    • Still undecided whether this should be a hash or a public key. A public key is nice for EoAs.
    • Embedding Bytecode
    • Updating Bytecode
    • Stealth/Diversified address derivation different from master address derivation?
  • Keys
    • Master keys
    • App-siloed keys
      • Security assumptions of each key
        • I.e. Which software/hardware is allowed to see each secret?
        • Example flows, to validate (and illustrate usage of) the keys.
      • BIP32
        • Normal key derivation
        • Hardened key derivation
        • Deviations from BIP32
    • Stealth keys vs Diversified keys
    • Updating keys
  • Which hash / prf / encryption scheme(s) to use?
