A burned certificate used to leave a name in the index forever: listed,
resolvable with its last records, and impossible to update or re-register.
REL is the declared burn. A transaction that spends the certificate from a
beacon transaction, recreates no output of its category and carries the REL
payload removes the name from the index.
The proof is read from an input because a burn leaves no output to read it
from. Resolvers hold only the beacon history, so the spent output must belong
to a beacon transaction; a certificate moved by a plain transfer is anchored
with an UPD first. That keeps the rule a pure function of the snapshot every
client already has.
A released name can be registered again only in a later block than the
confirmed release. Same-block re-registration would be decided by txid order
between a release and a snipe sitting in the mempool together.
This is the first step of ROADMAP-MAINNET.md §9: it puts burn detection in
the resolvers on its own, before any covenant depends on it. Specified in
PROTOCOL-ADDENDUM-release.md; shared resolver and its Ariadne copy here.
Every client hard-coded the chipnet beacons, address prefix and electrum
servers on its own: resolver, registrar config, wallets, gateway, indexer,
mirror scripts, the browser bundle and the mobile Java. A mainnet launch would
have meant finding all of them and hoping none was missed.
The table now lives in resolver-web.js, the one file every client already
shares, so it stays a single-file drop-in. BNS_NETWORK selects the record;
unset means chipnet, so nothing changes today: the live index resolves the
same 60 names and 20 TLDs, the 67 offline tests pass, and the dashboard,
market and studio load the same values through BNS.NETWORK.
The mainnet record carries the verified public servers, the prefix and its
own Sia bucket, but its beacons, start height and operator address are
deliberately null: requireBeacons() refuses to scan until they are pinned in
the order ROADMAP-MAINNET.md §6 requires. Bns.java reads a generated
BnsNetwork.java so the phone cannot drift from the desktop clients.
NETWORK-CONFIG.md records what reads the table and what a launch still pins.
Per-TLD certificates on a distinct TLD beacon supersede the legacy list-in-one-NFT
model. TLD label is the NFT commitment; TREG/TUPD payloads on the TLD beacon
mirror REG/UPD on the name beacon. Chipnet TLD beacon:

scripthash c85db10e106606273422b2733b2a6fb8b35a4d0e7dbfb20cf59bdb0833c008b8
* config.js, resolver-web.{js,d.ts} — TLD_BEACON + TLD_BEACON_SCRIPTHASH
* bns.js — KNOWN_OPS { REG, UPD, TREG, TUPD }, registerTld/updateTld/normalizeTld
* bns.js + resolver-web.js — buildIndex({enforceTld:false}) drops name REGs
whose TLD lacks a live TLD cert at their block height (mempool-friendly).
Lockstep across both files.
* lib/tld-index.js — buildTldSnapshot({history,txs}) → deterministic root over
canonicalised tlds[]. Pure, importable, and stable across insertion order.
* indexer/bns-indexer.js — BeaconIndex is multi-beacon; ws handler dispatches
by scripthash; new HTTP endpoint GET /tld-list.json + /health behind
BNS_HTTP_PORT; state file v1 → v2 migrates in fromJSON.
* publish-tld-mirror.mjs — S3 (floating + immutable content-addressed) plus
NIP-33 kind 30078 d:bns-tld-list to Nostr relays, signed via nostr-tools
(libauth's Schnorr differs from BIP-340 and relays reject it).
* seed-tld-beacon.mjs — idempotent chipnet seed. Current set on the beacon:
bch p2p bit nav test x asm neo gt sc sia com dex cex nt (15). `.com` is
held by the operator: cert on-chain, excluded from public registrar UI.
Design + docs:
* Decentralized.DNS/DESIGN-tld-registry.md — schema, enforcement,
operator-countersig gate, USD-tiered pricing floors, fee splits,
tracker/mirror mechanics, migration/grandfathering.
* INSTRUCTIONS.md §3 rewritten for the 4-step flow (TREG → UI → deploy →
republish snapshot).
* site/tlds/ — public docs page listing current TLDs + verification paths.
* site/sirius/register.html — dropdown removed; parallel search across
every TLD in the TLDS array, sorted available → taken → not-on-registry.
Config:
* ariadne.config.json tlds → [bch, p2p, bit, nav, test, x] (CA constraints;
on-chain registry is now the authoritative source, config is fallback).
* setup/install.ps1 — reads TLD list via fetchTldList (per-TLD registry)
with fallback to fetchBcnrTlds (legacy tls.bch list-NFT) then config.
Tests:
* test/tld-index.test.mjs — 30 self-contained checks (multi-beacon dispatch,
state migration, ws routing, snapshot shape + root recomputability).
* test/tld-enforcement.test.mjs — synthetic + live chipnet integration
(with-gate correctly drops all pre-seed names).
