Prototype implementation of the encoding and decoding framework for the secure fountain architecture (for python 3.8+)
The secure fountain architecture offers a quantum-resistant off-chain approach for reducing node storage requirements (with a tradeoff of increased bandwidth), without compromising blockchain verifiability.
This prototype library is blockchain-agnostic. Since the secure fountain architecture is simply an opt-in decentralized peer-to-peer storage layer, it can be run alongside the existing message distribution and storage system (with no changes to the underlying consensus protocol).
(Note that quantum resistance relies using a quantum-secure hash function, of which there are many)
