Abstract:
We present CellTree, a new architecture for distributed data repositories, as an alternative to blockchains. A CellTree allows data to be stored in largely independent, and highly programmable cells, which are "assimilated" into a tree structure. The data and the program of a cell can change over time, as dictated by the cell's program. In contrast with a blockchain which is replicated across many parties, no single party is required to store all the data in a CellTree. We present a simple instantiation of this architecture, with provable guarantees of liveness, correctness and consistency (the last one being a generalization of the typical blockchain guarantee of 'persistence', when data is dynamic). These properties can be guaranteed for individual cells that satisfy requisite trust assumptions, even if these trust assumptions do not hold for other cells in the tree. We also discuss several other features of a CellTree that can be exploited by applications. This is a joint work with Prof. Manoj M. Prabhakaran and Akash Trehan.
