  • Venti / Fossil, apparently pioneered the idea of recursive content-addressable file systems.

• Monotone’s “Certificates” are similar to Perkeep claims. (See terminology)

Probably more, though. Contributions to this list are welcome!

See the comparison page for more details on how Perkeep compares to other software and services.
