As an append-only distributed database, blockchain is utilized in a vast variety of applications including the cryptocurrency and Internet-of-Things (IoT). The existing blockchain solutions have downsides in communication and storage efficiency, convergence to centralization, and consistency problems. In this paper, we propose LightChain, which is the first blockchain architecture that operates over a Distributed Hash Table (DHT) of participating peers. LightChain is a permissionless blockchain…

LightChain: Scalable DHT-Based Blockchain

Compared to the mainstream blockchains such as Bitcoin and Ethereum, LightChain requires around 66 times smaller per node storage, and is around 380 times faster on bootstrapping a new node to the system, and each LightChain node is rewarded equally likely for participating in the protocol.

Joulin: Blockchain-based P2P Energy Trading Using Smart Contracts

This paper proposes, design and analyze a marketplace for energy trading based on smart contracts on the blockchain named Joulin, which serves as a competitive and efficient marketplace where peers can both produce, buy and sell energy depending on their needs.

Scalable Peer-to-Peer Fog Computing Integrated to a Fast-Searching Distributed Blockchain System

The design of fog-IoT with new chord algorithm is implemented in network simulator-3 and the results are evaluated in terms of latency, response time, blockchain size and network usage.

On the Deployment of Blockchain in Edge Computing Wireless Networks

This paper proposes a novel consensus mechanism adapted to the heterogeneity and dynamicity, e.g., mobility, of edge computing nodes, called adaptive blockchain for edge computing (ABEC), and demonstrates the superiority of ABEC over baseline consensus, in terms of block addition/confirmation latency and robustness to the edge nodes’ unreliable behaviour.

Blockchain and DHT Based Lookup System Aiming for Alternative DNS

This paper describes the current system structure and reports the result of measuring how the query time required for a lookup to any data changes depending on the network size and the ratio of off-line nodes.

Architecture of the Hyperledger Blockchain Fabric

A report of Swanson compares the two models of blockchains, where anyone can operate a node and participate through spending CPU cycles and demonstrating a “proof-of-work” in the “permissioned” model.

RapidChain: Scaling Blockchain via Full Sharding

RapidChain is proposed, the first sharding-based public blockchain protocol that is resilient to Byzantine faults from up to a 1/3 fraction of its participants, and achieves complete sharding of the communication, computation, and storage overhead of processing transactions without assuming any trusted setup.

Hyperledger fabric: a distributed operating system for permissioned blockchains

This paper describes Fabric, its architecture, the rationale behind various design decisions, its most prominent implementation aspects, as well as its distributed application programming model, and shows that Fabric achieves end-to-end throughput of more than 3500 transactions per second in certain popular deployment configurations.
