Exploring Privacy and Security Risks in Blockchain Ecosystems

Blockchain technology, which creates a linear, time-stamped, publicly distributed ledger of all transactions within a system, has the potential to facilitate many transactions—for instance, by potentially replacing time-consuming notary operations in asset transfer, or providing an immutable source of transactional or contract data. But despite this potential, there are sizeable cybersecurity, privacy, and service risks and concerns associated with blockchain adoption. This project proposes to explore the adoption landscape beyond its current usage in Bitcoin crypto-currency (i.e., possible applications that have received seed funding or are being proposed), and the specific privacy, cybersecurity, and availability challenges and risks associated with public and private blockchain.
