How to find my transaction from root of Merkle Tree How could I verify my transaction from the root of Merkle Tree.
First of all, you need to use gettxoutproof

$ bitcoin-cli help gettxoutproof
gettxoutproof ["txid",...] ( "blockhash" )

Returns a hex-encoded proof that "txid" was included in a block.
...


you receive data including your transaction id with another txids (privacy purpose).
then you need create empty merkle tree and place txids inside leafs, check this link to know how you can do it. You need to work even with little and big endian

After that you have to concat leafs and do SHA256 twice until the merkle root.
