Token Standard

[lastmjs]

These are my thoughts on the ideal token standard. I don't plan on implementing my own, I just want to use this information to inform discussions around coming to consensus on a standard as a community:

• [ ] accounts and balances
• [ ] account identifiers (principals or addresses??)
• [ ] transfer
• [ ] transfer_safe
• [ ] transfer delegations? (the ability to delegate the power to transfer to other accounts)
• [ ] history
  • [ ] blocks?
• [ ] verifiability
  • [ ] validity proofs?
  • [ ] blocks?
  • [ ] verifying the ledger itself and the implementation itself
• [ ] privacy
  • [ ] should blocks be publicly exposed?
  • [ ] should blocks/transactions only be exposed to participants in a transaction?
• [ ] DOS prevention
• [ ] Notifications
• [ ] Receipts (a transfer would atomically return a verifiable receipt of the transfer that could be passed along to interested parties)
• [ ] Atomicity (this might negate the need for receipts, as transfers could occur atomically with other update calls)
• [ ] Extensibility (this might be covered just fine by a canister's ability to extend itself)
• [ ] Fungibility? Should we have two standards are one standard?
• [ ] Automatic cycles top-up (cycles bonding curve?)
• [ ] Transaction fees
• [ ] Subnet size (we may want to agree upon the replication factors of subnets depending on the security requirements of a token)
• [ ] Scalability (transaction throughput and storage)
• [ ] Formal verification
• [ ] Property-based tests
• [ ] Multiple independent audits
• [ ] Test suite that other implementations can use
• [ ] Minting, burning, or fixed supply
• [ ] Who should be allowed to pay for fees? I think fees should always be payable in the token, but perhaps the receiver should be allowed to pay the fee

Current Proposed Token Standards

• [ ] IS20
• [ ] DIP20
• [ ] Extendable Token Standard
• [ ] Deland Labs fungible-token-standard

ICRC-1 has been adopted by the NNS

I'm going to close the issue as Demergent Labs probably won't be very involved in future token standards. The standards process is progressing along for now, and we can push forward initiatives ad-hoc if we need them.

This issue will be useful for future ideas still.
