Local Dev 4fb37e0683 bns: a registration is void unless its certificate is the only token of its category
Ownership of a name is proven by holding a token of its category: an update
is accepted when some output carries it. Nothing required that the
certificate be the only such token. Whoever registered a name could mint a
second one in the same transaction, a minting token for instance, sell the
certificate on the market, and later publish an update the resolvers would
accept. The buyer would hold the certificate and lose the name.

A registration now counts only if its category is created by that very
transaction, exactly one output carries it, and that output is an NFT with
no capability and no fungible amount. Nothing meeting this can ever have a
sibling. The same holds for TLD certificates, whose category proves the
right to set a TLD's policy and to co-sign registrations under it.

One definition, in resolver-web.js; bns.js and the TLD snapshot builder call
it. Every valid registration on chipnet already satisfied the rule: the live
registry is the same 71 names and 21 TLDs before and after.

Found while writing the delivery escrow, which had to forbid exactly this.

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 builders
  • src/wallet-app.js — wallet + embedded resolver + browser UI (npm run wallet → http://localhost:4626)
  • src/register.js / src/update.js / src/resolve.js — CLI equivalents
  • wallets.json — chipnet seed phrases (TESTNET ONLY — never reuse for real funds)
  • src/lib/gen-wallets.js — one-time wallet generation (already run)

Setup

  1. npm install
  2. 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.
  3. npm run wallet and open http://localhost:4626

Standalone resolver daemon (make EVERY browser resolve .bch)

  • src/daemon/bnsd.js — DNS server (answers *.bch from 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, then node 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 .bch queries 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.
  • 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.

Try it

  • Register hello with inline HTML (a website stored entirely on-chain), then type hello.bch in the address bar — the app resolves it from the blockchain (not DNS) and renders it.
  • Or CLI: node src/register.js hello '{"h":"<h1>Served from the BCH chain</h1>"}' then node src/resolve.js hello
