Rekkel Trees and Verifiable Database Systems

The chapter delves into Rekkel trees, which store recursive proofs for specific subsets of Merkle trees and enable computations on historic data. It explains the efficiency of computing proofs in a massively parallelizable manner in a blockchain setting. The discussion also covers the development of a Verifiable Database System called Supercells based on Rekkel trees, mapping SQL operators to the MapReduce framework for verifiability and exploring challenges in query decomposition.
