Files on Bitcoin
Every B:// file in the blocks Bitblocks stores, newest first. Each one is read from its transaction as this page loads.
B:// is the file protocol unwriter published in 2019: a file's bytes, media type and name in one transaction output.
A file's C:// address is the sha256 of its bytes, so every copy of the same file shares it.
Files open at
/b/<txid>
as untrusted content, with scripts switched off.

The list grows as the sync stores more blocks. B:// and C:// are unwriter's conventions; this is an independent reading of them from the chain. For a namespace's own files and routes, see the Bitcom registry .
