Local Dev ef0e7e430c feat(argus): POST /api/icon-upload route for Deviant Potidaea Katalogos icons
Content-addressed image upload for the DVMB icon sidecar (see the
Deviant repo commit 'in-browser Sia upload' for the client side).

Request
  POST /api/icon-upload
  Content-Type: image/(svg+xml|png|jpeg|gif|webp|x-icon)
  body:       raw image bytes (≤ 128 KB)

Response
  { sha256, ext, path: "s3://bns/potidaea/icons/<sha256>.<ext>",
    url:  "https://navigate.st/bns/potidaea.asm/icons/<sha256>.<ext>",
    bytes }

Why no auth
  Content-addressed: the key IS the SHA-256, so a re-upload of the same
  bytes overwrites itself harmlessly, and a spammer only pollutes their
  own hash-space. The on-chain iconSha256 field (DVMB chunk 5) ties an
  entry NFT to specific bytes — a rogue upload can't hijack another
  asset's icon.

Guards
  • content-type whitelist (only real image formats)
  • 128 KB body cap enforced during read (early destroy on overflow)
  • CORS * — safe, since we never touch per-user state
  • OPTIONS preflight handled for browsers that trigger one

  https://navigate.st/api/icon-upload
Smoke: browser JS POST returned 200 with the expected content-
addressed URL; a later GET of that URL returned matching bytes.

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
