Yalın PalaI wrote a small blog post about using Merkle trees in Go — not for blockchains this time, but just to track changes in a local folder.
It watches file contents, recalculates a Merkle root, and can even verify proofs or visualize the tree in your terminal.
Nothing fancy — just a fun and useful exercise.
