Beyond the Hype: On Using Blockchains in Trust Management for Authentication
, 2017 Trust Management (TM) systems for authentication are vital to the security of online interactions, which are ubiquitous in our everyday lives. Various systems, like the Web PKI (X.509) and PGP's Web of Trust are used to manage trust in this setting.

2016 IEEE 15th International Symposium on Network Computing and Applications (NCA), 2016 Most popular blockchain solutions, like Bitcoin, rely on proof-of-work, guaranteeing that the output of the consensus is agreed upon with high probability. However, this probability depends on the delivery of messages and that the computational power of the system is sufficiently scattered among pools of nodes in the network so that no pool can mine ...

A Logic of Blockchain Updates [PDF]
arXiv, 2017 Blockchains are distributed data structures that are used to achieve consensus in systems for cryptocurrencies (like Bitcoin) or smart contracts (like Ethereum). Although blockchains gained a lot of popularity recently, there is no logic-based model for blockchains available.

Distributed Nonblocking Commit Protocols for Many-Party Cross-Blockchain Transactions [PDF]
arXiv, 2020 The interoperability across multiple blockchains would play a critical role in future blockchain-based data management paradigm. Existing techniques either work only for two blockchains or requires a centralized component to govern the cross-blockchain transaction execution, neither of which would meet the scalability requirement. This paper proposes a

A Framework for Blockchain-Based Applications [PDF]
arXiv, 2018 Blockchains have recently generated explosive interest from both academia and industry, with many proposed applications. But descriptions of many these proposals are more visionary projections than realizable proposals, and even basic definitions are often missing.

State sharding model on the blockchain [PDF]
arXiv, 2020 Blockchain is an incrementally updated ledger maintained by distributed nodes rather than centralized organizations. The current blockchain technology faces scalability issues, which include two aspects: low transaction throughput and high storage capacity costs. This paper studies the blockchain structure based on state sharding technology, and mainly

The Cost of Trust: A Pilot Study
The Journal of The British Blockchain Association, 2018 Trust is a fundamental precondition underpinning exchange and economic coordination but is costly to maintain. Given the potential for agents to enjoy zero-sum gains by opportunistically betraying the trust of exchanging counterparties, an edifice of ...
