Block 0 · where it all starts
Bitcoin is still the leading technology.
Fifteen years in, Bitcoin remains the reference point for everything else in this space. Its code is open, its network has run without pause, and its design — proof-of-work, a fixed supply, no central operator — is the benchmark we measure every listing against.
That is why the basetfi.com index begins with Bitcoin Core and the ecosystem around it: open wallets, full nodes, Lightning tooling and block explorers. If you are new, start there. Understand the original, and the rest of the industry makes far more sense.

Word of mouth
What readers say.
“I send every newcomer to basetfi.com before I send them anywhere else. It saves me an hour of explaining which sites to trust.”
“The version tags and hash chips sound like a gimmick until you realise you can see, at a glance, whether a project is still alive.”
“Our little explorer got listed last spring. The review was genuinely thorough — they caught a broken link in our docs before we did.”
