A set of tools for handling functions related to the NANO cryptocurrency protocol.


  • Solve and verify proof-of-work
  • Create and deserialize legacy and universal blocks
  • Account generation from seed using the same algorithm as the original NANO wallet and NanoVault
  • Functions for converting between different NANO denominations
  • High performance cryptographic operations using C extensions (signing and verifying blocks, and generating block proof-of-work)
    • Proof-of-work generation supports SSE2, SSSE3, SSE4.1, AVX and NEON instruction sets for improved performance. The best supported implementation is selected at runtime with a fallback implementation with universal compatibility.
  • Backed by automated tests
  • Compatible with Python 3.6 and up
  • Licensed under the very permissive Creative Commons Zero license


An online copy of the documentation can be found at Read the Docs.

You can also build the documentation yourself by running python build_sphinx.


The script comes with a few additional commands besides installation:

  • build_sphinx
    • Build the documentation in build/sphinx/html.
  • test
    • Run tests using pytest
  • speed
    • Run a benchmark testing the performance of various cryptographic operations used in the library.



You can’t perform that action at this time.
