- /* WARNING! If you're reading this because you're learning about crypto
- and/or designing a new system that will use merkle trees, keep in mind
- that the following merkle tree algorithm has a serious flaw related to
- duplicate txids, resulting in a vulnerability (CVE-2012-2459).
-
- The reason is that if the number of hashes in the list at a given time
- is odd, the last one is duplicated before computing the next level (which
- is unusual in Merkle trees). This results in certain sequences of
- transactions leading to the same merkle root. For example, these two
- trees:
-
- A A
- / \ / \
- B C B C
- / \ | / \ / \
- D E F D E F F
- / \ / \ / \ / \ / \ / \ / \
- 1 2 3 4 5 6 1 2 3 4 5 6 5 6
-
- for transaction lists [1,2,3,4,5,6] and [1,2,3,4,5,6,5,6] (where 5 and
- 6 are repeated) result in the same root hash A (because the hash of both
- of (F) and (F,F) is C).
-
- The vulnerability results from being able to send a block with such a
- transaction list, with the same merkle root, and the same block hash as
- the original without duplication, resulting in failed validation. If the
- receiving node proceeds to mark that block as permanently invalid
- however, it will fail to accept further unmodified (and thus potentially
- valid) versions of the same block. We defend against this by detecting
- the case where we would hash two identical hashes at the end of the list
- together, and treating that identically to the block having an invalid
- merkle root. Assuming no double-SHA256 collisions, this will detect all
- known ways of changing the transactions without affecting the merkle
- root.

+ /* WARNING! If you're reading this because you're learning about crypto
+ and/or designing a new system that will use merkle trees, keep in mind
+ that the following merkle tree algorithm has a serious flaw related to
+ duplicate txids, resulting in a vulnerability (CVE-2012-2459).
+
+ The reason is that if the number of hashes in the list at a given time
+ is odd, the last one is duplicated before computing the next level (which
+ is unusual in Merkle trees). This results in certain sequences of
+ transactions leading to the same merkle root. For example, these two
+ trees:
+
+ A A
+ / \ / \
+ B C B C
+ / \ | / \ / \
+ D E F D E F F
+ / \ / \ / \ / \ / \ / \ / \
+ 1 2 3 4 5 6 1 2 3 4 5 6 5 6
+
+ for transaction lists [1,2,3,4,5,6] and [1,2,3,4,5,6,5,6] (where 5 and
+ 6 are repeated) result in the same root hash A (because the hash of both
+ of (F) and (F,F) is C).
+
+ The vulnerability results from being able to send a block with such a
+ transaction list, with the same merkle root, and the same block hash as
+ the original without duplication, resulting in failed validation. If the
+ receiving node proceeds to mark that block as permanently invalid
+ however, it will fail to accept further unmodified (and thus potentially
+ valid) versions of the same block. We defend against this by detecting
+ the case where we would hash two identical hashes at the end of the list
+ together, and treating that identically to the block having an invalid
+ merkle root. Assuming no double-SHA256 collisions, this will detect all
+ known ways of changing the transactions without affecting the merkle
+ root.
