Tendermint updated their simple merkle tree to the following:

leaf nodes and inner nodes have different hashes. 
This is for "second pre-image resistance", to prevent the proof to an inner node being valid as the proof of a leaf. 
The leaf nodes are SHA256(0x00 || leaf_data), and inner nodes are SHA256(0x01 || left_hash || right_hash)

This can be seen here
