A Merkle Tree toy using monocypher. This little bag of tools is sufficient to construct Merkle Roots, and verify Merkle Proofs.
NOTE: This is not production-grade software, and I am not a cryptographer, implementing crypto nearly from-scratch. It takes multiple short-cuts and doesn't exhaustively handle error cases. You should not use this for anything serious.
Use this only as a means of learning and education!
Cf. my rationale, and the basic usage.
