Abstract
Blockchain and Distributed Ledger Technology (DLT) have exploded in popularity since the widespread adoption of Bitcoin and Ethereum, however the field is still very young and applications outside financial technology are especially juvenile. This dissertation seeks to improve the properties of DLTs for low-power IoT networks, computational marketplaces, mining pools, and mobile ad-hoc networks. DLTs suffer from a few pivotal inefficiencies holding these applications back: scalability, power consumption, cyber-physical implementation, and consensus latency. The novel contributions include Mechanisms for Outsourcing Computation via a Decentralized Market (MODiCuM), a platform for clearly defined computational tasks. PoolParty, an efficient hierarchical blockchain-agnostic decentralized mining pool with a novel gossip network of mining proofs and Solidity implementation. A Survey of Spatial Aware DLTs covering the field of geospatial cyber-physical DLT research and applications, and and the gaps/challenges/direction of future work. Finally this dissertation includes a simulation of location-aware mobile IoTA network and hardware analysis of potential proximity-based consensus algorithms. This Simulation is the first of it鈥檚 kind to include mobile nodes in a DAG blockchain network and novel conversions of existing consensus algorithms to fit the unique constraints of this application. Hopefully these contributions to the field will help DLT research break out of the financial technology orthoodoxy and embrace new customizable methods of DLT creation for novel applications.
