Blockchain
Prism Research Laboratory Specialized Domain
Domain Overview
Blockchain is a decentralized and distributed ledger technology that enables secure, transparent, immutable, and trustless management of digital transactions and information without requiring centralized control. It has emerged as a revolutionary technology for building secure digital ecosystems with enhanced transparency, accountability, and tamper resistance.
Research in blockchain focuses on distributed consensus protocols, smart contracts, decentralized applications (DApps), cryptographic security, privacy-preserving mechanisms, scalability, interoperability, and trusted data sharing frameworks. Applications extend across multiple domains, including healthcare, supply chain management, digital identity, finance, governance, cybersecurity, and land registry systems.
Emerging directions include blockchain-enabled federated learning, decentralized AI, secure multi-party collaboration, permissioned blockchain frameworks (e.g., Hyperledger Fabric), Web3 ecosystems, and scalable consensus mechanisms for next-generation secure infrastructures.
