If that can help, take a look at the original code for the function gettxoutproof(), this is the function that takes a json array of txids and a block hash and returns a string that is a serialized, hex-encoded data for the proof. It will allow you to understand how the hex encoded version is constructed so you can do the opposite to decode it. https://github.com/bitcoin/bitcoin/pull/5199/files#diff-52257e4c1cedbf5e302f183065cab880R197 And here you can find the code for the verifytxoutproof() function: https://github.com/bitcoin/bitcoin/pull/5199/files#diff-52257e4c1cedbf5e302f183065cab880R277 You will also find a very good introduction with some ready-made code for merkle trees in this article: https://hackernoon.com/merkle-tree-introduction-4c44250e2da7 text/markdownUTF-8 answer.md
