Improving Smart Contracts Management and Designs for Blockchain Systems
Blockchain technology has a secure-by-design ledger in which a chain of blocks storing network transactions is permanently stored in the network nodes. It has significantly impacted domain-specific tracking and authenticity fields such as supply chain applications, tracking and tracing systems, and …

Skyllian : a flexible layer II solution for blockchain systems
Blockchains were initially designed to facilitate a basic peer-to-peer payment system. As the flora of blockchain applications proliferates, an inherent growth in complexity exists, posing significant challenges for developers seeking to design and deploy blockchain-based applications. There is a …

Systematic approach to analyzing security and vulnerabilities of blockchain systems
Recent hacks into blockchain systems and heists from such systems have raised serious questions about whether this new technology can be secured from ongoing, evolving cyberattacks. While the technology is known to provide an environment that is fundamentally safer than other existing centralized …

Design and development of a parallel Proof of Work for permissionless blockchain systems
Blockchain, which is the underlying technology for the Bitcoin cryptocurrency, is a distributed ledger forming a decentralized consensus in a peer-to-peer network. A large number of the current cryptocurrencies use blockchain technology to maintain the network and the peers use a consensus …

Liveness analysis, modeling, and simulation of blockchain consensus algorithms' ability to tolerate malicious miners
The blockchain technology revolution and concomitant use of blockchains in various applications have resulted in many organizations and individuals developing and customizing their own fit-for-purpose consensus algorithms. Because security and performance are principally achieved through the chosen …

Adapting Financial Technology Standards to Blockchain Platforms
<p>Traditional payment systems have standards designed to keep transaction data secure, but blockchain systems are not in scope for such security standards. We compare the Payment Application Data Security Standard’s (PA-DSS) applicability towards transaction-supported blockchain platforms to test …

An ECDSA Nullifier Scheme and a Proof of Identity Application
… by the adoption of cryptographic primitives in blockchain systems, ZK-SNARKs are rapidly becoming computationally practical in real-world settings, shown by i.e. tornado.cash and rollups. These have enabled ideation for new identity applications based on anonymous proof-of-ownership. One of the …

ON SCALABILITY OF BLOCKCHAIN TECHNOLOGIES
… we explore how to improve scalability of blockchains while maintaining their fundamental premise of decentralization. Scalable blockchains are capable of delivering a target throughput and latency in the presence of increasing workload. To this end, first we present Bitcoin-NG, a new …
