The Merkle tree is useful because it allows users to verify a specific transaction without downloading an entire blockchain—which can be hundreds of gigabytes in size.3For example, say that you wanted to verify that transaction TDis included in the block in the diagram above. If you have the...

Een Hash-boom, ook wel Merkle tree genoemd, is een datastructuur die gebruikt wordt in decryptografie, blockchains en sommige cryptocurrencies om de integriteit van data-elementen binnen een grotere dataset te verifiëren. Een Hash-boom bestaat uit blokken met gegevens die elk worden omge...

Sparse: A traditional binary merkle tree does not have a concept of an "empty" leaf. This means that the leaves must be in a sequence, for example 1 through N (with no gaps). This raises the question about what to do when N is not a power of two. Furthermore, adding new records...

Merkle tree: Each version of the database is a tree. The leaves of this tree are the inserted records which are combined together with calls to a cryptographic hash function, creating a smaller set of intermediate nodes. These intermediate nodes are then combined in a similar way to create ...
