Python library for working with the NANO cryptocurrency protocol

Project description


  • 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


You can install the library using pip:

` pip install nanolib `

nanolib requires a working build environment for the C extensions. For example, on Debian-based distros you can install the required Python header files and a C compiler using the following command:

` apt install build-essential python3-dev `


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.
