A month after the white paper went live at https://bip47db.github.io, Max Tannahill has created the tool and it is live: http://bip47db.org
Inscribe and browse BIP47 payment codes from your browser.
Mainnet ready, fully client-side, no server to trust.
The protocol whitepaper has been refined to v1.6 with community feedback, esp
@MightyMercurian.
If you missed the first tweet: BIP47 reusable payment codes solve real privacy problems but depend on directory services like http://paynym.rs.
Those are centralised. If they go down, wallet recovery from seed alone breaks for connections you've made.

BIP47DB inscribes the directory itself onto Bitcoin.
The Publisher tool walks you through inscribing a batch of payment codes:
– Fetch from http://paynym.rs (or paste manually): Sign a single message with your BIP47 wallet (@AshigaruFanClub/@SamouraiWallet)
– Cosign the funding tx with
@SparrowWallet: Up to 5,000 codes per batch. Validates the UTXO covers fees before you sign anything.
The Browse tab decodes inscriptions back into a searchable database.
Anyone can sync from a @mempool API endpoint and verify every record cryptographically.
There is no trust in the indexer, no trust in the publisher.
The whole site is static HTML + JS. The repo is open source.
The single CORS proxy he runs (for the http://paynym.rs fetch convenience) only relays one specific endpoint and rejects unknown origins.
If Max disappeared tomorrow, anyone could host this themselves in an hour.
The April tweet got a healthy mix of "this is cool" and "Ordinals are cancer.", and he's very grateful for all the technical feedback.
As for BIP110 signallers? He doesn't care what you think.

Mainnet inscriptions are now possible but no batches have been written yet.
I'm waiting for the first one to be by the community or Ashigaru, not me.
Have at it and make sure to join Freedom Tech Friday on the Ungovernable Misfits feed on May 15th @ 9 AM EST to get the full breakdown of this important tech!
