• Human-readable account numbers by @aivve in #243

Account Numbers (H–I–C Format)

Karbowanec now supports short, human-readable account numbers as an alternative to 95-character CryptoNote addresses. Account numbers are derived directly from a registration transaction's position on the blockchain — block height (H), transaction index (I), and a Luhn mod 36 check character (C) — producing compact identifiers like 1264265-1-W.

How it works: A user broadcasts a registration transaction containing their address. Once mined, the account number is permanently assigned — no central registry, no auctions, no new trust assumptions. The first registration for a given address is canonical; duplicates are ignored.

Key properties:

• Fully on-chain and deterministic — O(1) forward lookup, no external dependencies
• Luhn mod 36 checksum catches typos before any network query is made
• Spam-resistant by design — standard fees apply, duplicate registrations have no effect
• Backwards compatible — existing addresses and workflows are unaffected
• New RPC methods: resolveaccountnumber and getaccountnumber, see documentation
• Wallet integration for both sending (resolve + confirm) and receiving (register + display)

Note: Account numbers should be treated as unconfirmed until 10–60 blocks deep, mirroring standard confirmation practice. Users who prioritize address privacy should not register, as registration makes the address discoverable on-chain.
