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).
