Decentralized systems such as blockchains promise to fundamentally change how untrusted parties exchange data and assets. A key challenge in the decentralized setting is scalably authenticating data in the system. Merkle Patricia trees (MPT) are widely used in decentralized systems like Ethereum, to verify that the data is correct and up-to-date. Unfortunately, MPTs incur significant overhead due to random IO operations, serialization, and hashing. This paper presents the Distributed Merkle… Expand
