TLDR
A comprehensive review on the recent advances in architecture design and technology development towards tackling several critical challenges that are inherent in IIoT and blockchain themselves, such as standardization, scalability, and interoperability is provided.
SoK: Diving into DAG-based Blockchain Systems
TLDR
The security and performance of several leading systems are analyzed, followed by discussions and comparisons with concurrent (scaling blockchain) techniques, and open challenges are identified to highlight the potentiality of DAG-based solutions and indicate their promising directions for future research.
An Efficient and Compacted DAG-Based Blockchain Protocol for Industrial Internet of Things
TLDR
This article designs a CoDAG-based IIoT architecture based on a compacted directed acyclic graph, where blocks are organized in levels and width and illustrates the attack strategies by adversary, and it is proved that the protocols are resistant to these attacks.
A Survey of Distributed Consensus Protocols for Blockchain Networks
TLDR
This survey will provide blockchain developers and researchers a comprehensive view on the state-of-the-art consensus protocols and facilitate the process of designing future protocols.
Betting on Blockchain Consensus with Fantomette
TLDR
This paper proposes a secure leader election protocol, Caucus, and next fits this protocol into a broader blockchain-based consensus protocol, Fantomette, that provides game-theoretic guarantees in addition to traditional blockchain security properties, which is the first proof-of-stake protocol to give formal game- theoretic proofs of security in the presence of non-rational players.
Performance-Based Analysis of Blockchain Scalability Metric
TLDR
This paper attempts to present the existing scalability solutions which are broadly classified into three layers: Layer 0 solutions focus on optimization of propagation protocol for transactions and blocks, and Layer 1 solutions are based on the consensus algorithms and data structure.

  • 2020
TLDR
A two-step strategy for making the system robust to double-spend attacks by considering the ledger as Directed Acyclic Graph (DAG) called blockDAG instead of chain of blocks is proposed.
Scalable Consensus Protocols for PoW based Blockchain and blockDAG
TLDR
A new consensus protocol proposed by considering the ledger as a Directed Acyclic Graph (DAG) called blockDAG instead of a chain of blocks, which is suitable for smart contract applications found in Internet of Things (IoT) services.
Engineering Economics in the Conflux Network
TLDR
In detail, this paper parameterizes the level of income, and thus network security, that Conflux can generate, and it describes how this depends on user behavior and “policy variables” such as block and interest inflation.
SURFACE: A Practical Blockchain Consensus Algorithm for Real-World Networks
TLDR
SURFACE is a consensus algorithm that is designed for real-world networks and enjoys the benefits from both the Nakamoto consensus and Byzantine Fault Tolerance (BFT) consensus.

SPECTRE: A Fast and Scalable Cryptocurrency Protocol
TLDR
SPECTRE is presented, a new protocol for the consensus core of crypto-currencies that remains secure even under high throughput and fast confirmation times, and can operate at high block creation rates, which implies that its transactions confirm in mere seconds.
On Trees, Chains and Fast Transactions in the Blockchain
TLDR
This work studies from a provable security point of view the GHOST protocol, touted as offering superior performance compared to Bitcoin (potentially offering block production speed up by a factor of more than 40) without a security loss.
Enhancing Bitcoin Security and Performance with Strong Consistency via Collective Signing
TLDR
This paper introduces ByzCoin, a novel Byzantine consensus protocol that leverages scalable collective signing to commit Bitcoin transactions irreversibly within seconds, and achieves a throughput higher than PayPal currently handles, with a confirmation latency of 15-20 seconds.
Bitcoin-NG: A Scalable Blockchain Protocol
TLDR
This paper implements Bitcoin-NG, a new blockchain protocol designed to scale, which is Byzantine fault tolerant, is robust to extreme churn, and shares the same trust model obviating qualitative changes to the ecosystem.
