One decade ago, Bitcoin was introduced, becoming the first cryptocurrency and establishing the concept of “blockchain” as a distributed ledger. As of today, there are many different implementations of cryptocurrencies working over a blockchain, with different approaches and philosophies. However, many of them share one common feature: they require proof-of-work to support the generation of blocks (mining) and, eventually, the generation of money. This proof-of-work scheme often consists in the… Expand
TheChain: A Fast, Secure and Parallel Treatment of Transactions
TLDR
This work raises the following question: "Why is there a need for consensus where all participants can make a quick and correct decision?", and underlines the fact that sometimes ledger is subject to maintenance from regional parties in the data that leads to partial territories and eliminates monopoly, which is the hurdle to eliminating the trusted party.

A Proof of Useful Work for Artificial Intelligence on the Blockchain
TLDR
A novel 'proof of useful work' (PoUW) protocol based on training a machine learning model on the blockchain that aims to build better AI systems using the security of the blockchain and outline mechanisms to reward useful work and punish malicious actors. Expand
Innovation and Challenges of Blockchain in Banking: A Scientometric View
TLDR
The present study poses 3 empirical research questions: which are the current technologies within the blockchain ecosystem for competitive advantage to banking institutions, and how will blockchain based digital platforms transform existing value-creating interactions. Expand
Voting-Based Decentralized Consensus Design for Improving the Efficiency and Security of Consortium Blockchain
TLDR
This article introduces proof of assets and proof of reputation to design a voting-based decentralized consensus (VDC) algorithm for consortium blockchain that achieves a faster consensus process and better user fairness than existing algorithms while still maintaining a negligible energy cost and adequate security. Expand
Spy Based Analysis of Selfish Mining Attack on Multi-Stage Blockchain
TLDR
This paper presents selfish mining attack on the multi-stage blockchain proposed by Palash Sarkar, and introduces a spy inside an honest pool which is a trivial task, and redesigns the original verification algorithm by introducing a new parameter called the cryptostamp. Expand
Proof of Federated Learning: A Novel Energy-Recycling Consensus Algorithm
TLDR
This article is the first work to employ federal learning as the proof of work for blockchain and proposes a novel energy-recycling consensus algorithm, namely proof of federated learning (PoFL), where the energy originally wasted to solve difficult but meaningless puzzles in PoW is reinvested to Federated learning.

TLDR
This paper proposes a flexible consensus mechanism called proof of engagement (PoE), based on the activity and contribution of network nodes, and analyzes the incentive compatibility of PoE from the perspective of mechanism design. Expand
Analysis of Data Management in Blockchain-Based Systems: From Architecture to Governance
TLDR
This paper analyzes blockchains from the viewpoint of a developer to highlight important concepts and considerations when incorporating a blockchain into a larger software system as a data store and to promote a methodical approach in applying it to large software systems. Expand
Blockchain and Machine Learning for Communications and Networking Systems
TLDR
This paper identifies several important aspects of integrating blockchain and ML, including overview, benefits, and applications, and discusses some open issues, challenges, and broader perspectives that need to be addressed to jointly consider blockchain andML for communications and networking systems. Expand
A mining pool solution for novel proof-of-neural-architecture consensus
TLDR
This work adopts from exist Proof-of-Deep-Learning as the consensus and Neural Architecture Search as the workload and shows the performance of this mining pool is more competitive than an individual miner in conducting NAS as workload. Expand

A Proof of Work: Securing Majority-Attack in Blockchain Using Machine Learning and Algorithmic Game Theory
TLDR
This paper proposes a methodology where intelligent software agents can be used to monitor the activity of stakeholders in the blockchain networks to detect anomaly such as collusion, using supervised machine learning algorithm and algorithmic game theory and stop the majority attack from taking place. Expand
REM: Resource-Efficient Mining for Blockchains
TLDR
REM (Resource-Efficient Mining), a new blockchain mining framework that uses trusted hardware (Intel SGX), achieves security guarantees similar to PoW, but leverages the partially decentralized trust model inherent in SGX to achieve a fraction of the waste of PoW. Expand

Consensus from Signatures of Work
TLDR
This work formalizes a building block that is sufficient for designing consensus protocols in this setting where no authentication or even point-to-point communication is available and relies on a very strong independence assumption about adversarial accesses to the underlying computational resource.
