What this is

Search built for crypto infrastructure

CRYPTTRON is an independent search index covering one subject: crypto technical infrastructure — mining hardware, nodes, self-custody, protocol docs and developer tooling. It is not a Google front-end — it runs its own crawler, its own index, and its own ranking. Currently 1047 pages indexed across 37 source domains.

How it evolves

1 · It learns from clicks

Every result you click is a vote. Rankings combine text relevance (BM25) with a learned per-page score built from click-through rate, corrected for position bias (a click at rank 1 proves less than a click at rank 9) and shrunk toward zero until there's real evidence — so one lucky click can't hijack a query. The learned score is capped, so it can never fully override relevance.

2 · It mines its own gaps

A search that returns nothing — or returns results nobody clicks — is recorded as a coverage gap. On the next cycle the crawler turns those gaps into crawl targets inside the vertical, fetches what it finds, and indexes it. The index grows toward the questions people actually ask instead of toward whatever was seeded.

3 · It schedules its own re-crawls

Each page carries its own refresh interval. A page that changed since last visit is revisited sooner; a page that never changes backs off to monthly. Crawl budget follows observed volatility, so firmware release pages stay fresh while static spec sheets stop being re-fetched.

Anonymous login — how Bit-SIGN works

You can search without an account. If you want one, Bit-SIGN is an anonymous, passwordless login: no email address, no password, no name, no phone number and no identity check. Your account is a Bitcoin key.

How it works, in three steps. The site shows you a one-time line of text. You sign that line with a wallet you already control — or with the key directly, from a terminal. You paste the signature back, and the maths proves you hold the key without ever revealing it. That signature is the login.

What it protects. There is no password to steal, so nothing can be phished, reused or dumped in a breach — a signature made for this site is useless anywhere else. There is no email address, which is the thread that normally ties an account to your real identity and to every other service you use. No tracking pixels, no advertising identifiers, no third-party analytics, no data brokers. Identity protection here is structural: the data cannot leak because it was never collected.

It cannot touch your coins. Signing text is arithmetic on a key. It creates no transaction, pays no fee and writes nothing to the blockchain. We never connect to your wallet — you copy a line out, sign it on your own device, and paste a signature back. A signature proves you hold a key; the balance behind it is never looked at, and if you would rather not use a funded wallet, an empty one works exactly as well.

Bit-SIGN makes you pseudonymous — strong privacy from us, from advertisers and from a breach. Your public key is visible on your profile, because that is how people verify who they are talking to. ▶ Watch the 90-second walkthrough · Create an anonymous account · Which wallets can sign · What we record

Curated on purpose. A domain is either in the vertical or it isn't — links outside this list are dropped rather than followed, which is exactly why the index stays clean at a size one person can run.

Search API

The index is available as a JSON API for developers and agents:

curl -H "X-API-Key: pk_…" "/api/search?q=bm1370+efficiency&limit=10"
