Ralph Merkle appreciation. One stop source for the most scholarly articles on …1 Answer. Updating a Merkle hash tree is trivial. For instance, if you want to update a leaf, then you update it and then update every node on the path from it to the root. If you have a particular operation on the tree in mind, the necessary updates follow immediately from the kind of update you want to do. brain drain A Merkle proof is the values to hash together with the value being proved to get back the Merkle root. The value to prove is often available from other data, so I prefer to provide it separately rather than as part of the code. 1 // A merkle proof consists of the value of the list of entries to. 2 // hash with.verifyCalldata takes in the proof itself as bytes32 array, the Merkle root hash and the leaf we want to verify for inclusion. Typically the root will be data you store in the smart contract and proof will be the data from someone created off-chain, proving to the contract that the leaf was part of the original tree..
