WebApr 13, 2024 · Sets and maps are nonlinear data structures that store data elements in a hash table, which is a collection of key-value pairs. Sets store only the keys, while maps store both the keys and the values. WebJul 28, 2024 · A Merkle tree adds up all of the transactions in a block and creates a unique digital fingerprint of the full set of instructions, allowing the user to check whether the block contains a transaction. Merkle trees are created by continuously hashing pairs of nodes until only one hash remains, known as the root hash or Merkle root.

WebWhen read into memory, the block is hashed in parallel. The hash is then verified up the tree. And since reading the block is such an expensive operation, the latency introduced by this block-level verification is comparatively nominal. After the block is read and hashed, it is verified up the tree. WebIn C++, the hash is a function that is used for creating a hash table.
