Every second-level name registration under a TLD now routes 90% of the
service fee to whoever holds that TLD's certificate on chain, with 10%
going to the platform address. That's the economic incentive for
minting a TLD: you earn from every name registered under it.
The mechanism, end to end:
1. resolver-web.js fetchTldMap now also records mintScriptHex — the
scriptPubKey of the TREG output that carries each TLD's NFT.
Exported so registrar can decode it into a cashaddr with libauth.
MVP: this is the ORIGINAL owner; NFT transfers after mint are not
traced yet (a follow-up will walk the chain of transfers).
2. registrar.js gains findTldOwnerAddress(client, tld) and
splitServiceFee(sats). The split constants live at the top of the
file (TLD_OWNER_SHARE_NUM/DEN = 90/100) so the ratio moves in one
place. Rounding: BigInt division favours the platform on odd sat
counts so the two shares always sum EXACTLY to the input.
3. quoteRegistration wraps the existing flow: it derives the TLD from
the name, looks up the TLD owner, and if the owner ≠ buyer it asks
buildRegistrationTx to add a second fee output. If the owner
couldn't be resolved (TLD not registered, decode failure) the full
fee stays on the platform address — the buyer still pays the same
amount either way.
4. register-tx.js buildRegistrationTx accepts tldFeeAddress/tldFeeSats
and, when set, emits an extra P2PKH output for the TLD owner. Sits
between the beacon dust and the platform-fee output; outputMap
records .tldOwnerFee so callers can find it. costs also carries
tldOwnerFeeSats and netCostSats includes it.
5. priceSummary in registrar-config splits the 'Service fee' row into
'Service fee — TLD owner (90%)' + 'Service fee — platform (10%)'
whenever tldOwnerFeeSats > 0, with a per-line note explaining
where the money goes.
Bundle: re-exported findTldOwnerAddress + splitServiceFee from
register-entry.js. Rebuilt bns-register.js (~34 kB) and deployed;
cache-buster bumped to ?v=20260908split on portal / admin /
register-flow.js.
Verified live: findTldOwnerAddress('.bch') returns the operator
cashaddr; quoteRegistration('tester42.bch') builds cleanly with a
9,000/1,000 split output pair on a 10,000-sat fee; priceSummary
renders both lines. No regressions on the TLD-mint flow (buyer IS
the TLD owner there — split short-circuits and it stays a single
fee output as before).

BNS — Namecoin-style decentralized names on Bitcoin Cash (chipnet)
A working prototype of "Option 3": names are CashTokens name certificates on the BCH chain (no fork, no sidechain), records ride in OP_RETURN, discovery via a beacon address, and the resolver is embedded in a wallet app with a built-in browser pane — the Brave/MetaMask-browser architecture in miniature.
See PROTOCOL.md for the on-chain design and its honest limitations.
Layout
src/lib/bns.js— protocol core: payload codec, chain indexer/resolver, tx builderssrc/wallet-app.js— wallet + embedded resolver + browser UI (npm run wallet→ http://localhost:4626)src/register.js/src/update.js/src/resolve.js— CLI equivalentswallets.json— chipnet seed phrases (TESTNET ONLY — never reuse for real funds)src/lib/gen-wallets.js— one-time wallet generation (already run)
Setup
npm install- Fund the wallet with free chipnet tBCH: go to https://tbch.googol.cash/,
paste the wallet address (shown in the app sidebar or by
node src/lib/gen-wallets.js), pick chipnet, solve the captcha. ~0.001 tBCH funds hundreds of registrations. npm run walletand open http://localhost:4626
Standalone resolver daemon (make EVERY browser resolve .bch)
src/daemon/bnsd.js— DNS server (answers*.bchfrom the chain, forwards everything else upstream) + HTTP gateway that serves on-chain sites by Host header. Test unprivileged:node src/daemon/bnsd.js --dns-port 5354 --http-port 8081, thennode src/daemon/dig.js hello.bch.setup/install.ps1— run from an elevated PowerShell. Installs the daemon as a boot-time scheduled task (SYSTEM, auto-restart) and wires the OS to it:- default (
-Mode nrpt): adds an NRPT rule so only.bchqueries reach the daemon; all other DNS is untouched. -Mode full: points every adapter's DNS at 127.0.0.1 (daemon forwards non-.bch upstream, ncdns-style); original servers are saved and restored on uninstall.
- default (
setup/uninstall.ps1— reverses everything (rule/adapters/task).
HTTPS for .bch: the "BNS Local Root CA" (created on demand in ca/, keep
root-ca.key private) signs per-name certs. The daemon's :443 gateway mints
them on the fly for locally-served names; node src/lib/issue-cert.js <name>
issues one for a real server (see the coinspectrum.bch nginx vhost). The
installer trusts the root machine-wide and enables Firefox's
enterprise-roots policy; cert fingerprints are published in "tls" chain
records for pinning.
Caveats: browsers with "secure DNS" (DoH) enabled bypass the OS resolver — disable it or add an exception; ports 53/80/443 must be free.
