PUZZLE #5193: Merkle Proof (diff 4)
Verify that leaf 'ROOT3' belongs in a 5-deep Merkle tree. Reconstruct root from leaf + proof hashes.
DATA
| Leaf |
ROOT3
|
| Leaf Index |
31
|
| Proof |
{'pos': 'left', 'hash': 'CHAIN1'}, {'pos': 'left', 'hash': '7e8a6519'}, {'pos': 'left', 'hash': 'b6bee0e7'}, {'pos': 'left', 'hash': '7cadc139'}, {'pos': 'left', 'hash': 'a66fcc1e'}
|
| Root |
277edab0
|
| Depth |
5
|
| Tree Size |
32
|
| Hint |
Given the leaf 'ROOT3' at index 31 and the proof path of 5 hashes, reconstruct the Merkle root and compare with '277edab0'. If they match, the leaf is valid — submit the leaf as the answer.
