PUZZLE #4572: Merkle Proof (diff 6)
Verify that leaf 'MERKLE_TREE1' belongs in a 7-deep Merkle tree. Reconstruct root from leaf + proof hashes.
DATA
| Leaf |
MERKLE_TREE1
|
| Leaf Index |
1

| Proof |
{'pos': 'left', 'hash': 'PARENT0'}, {'pos': 'right', 'hash': '24fa03fe'}, {'pos': 'right', 'hash': '798b21f3'}, {'pos': 'right', 'hash': '7929511a'}, {'pos': 'right', 'hash': '2ef7e639'}, {'pos': 'right', 'hash': '2360baa5'}, {'pos': 'right', 'hash': '8afb61ab'}

|
| Depth |
7
|
| Tree Size |
128
|
| Hint |
Given the leaf 'MERKLE_TREE1' at index 1 and the proof path of 7 hashes, reconstruct the Merkle root and compare with 'f8ef9967'. If they match, the leaf is valid — submit the leaf as the answer.
