Definition: Verkle tree

(VEctor commitment MeRKLE tree) A more efficient version of a Merkle tree that uses a different type of hash function. Like a Merkle tree, a Verkle tree is used to provide a digest (footprint) of transactions in a blockchain. However, instead of proving all the hashes in the tree individually, the Verkle tree can be verified with a single proof. Ethereum 2.0 is switching to Verkle trees. See Merkle tree and Ethereum 2.0.
