Cryptostamps

what is cryptostamps?

cryptostamps sits at the intersection of philately and blockchain: physical collector stamps paired with digital tokens recorded on a chain, so ownership and provenance of a stamp can be verified independently of any central registry. the project's site is reachable over tor at the address tracked here, which is convenient for collectors who manage their holdings from anonymised environments.

projects like this illustrate how routine onion hosting has become outside the headline-grabbing markets: any service whose operators value reachability under censorship - or simply want to offer privacy-minded users a direct route - can run one, usually with little extra effort.

consistent with the rest of this list, our checker treats the site like any other tracked service: periodic connections through the tor network, response-time measurement and a rolling seven-day uptime record shown below.

before you trust any of this

• .onion addresses are long on purpose. one wrong letter = someone else's server.
• if a service matters to you, cross-check its address against its own clearnet site or PGP-signed announcements.
• a green badge here means "reachable", never "trustworthy". we report reachability only.
