This document discusses how blockchain technology can provide advantages for information security. It begins by explaining key concepts of blockchain like wallets, hashing, consensus, and smart contracts. It then discusses specific blockchain platforms like Bitcoin and Ethereum, as well as how blockchain acts as a decentralized ledger. The document outlines some cryptocurrencies and then discusses how blockchain can help with challenges in identity management, asset management, and software license/installation management. It poses these areas as questions for whether blockchain could provide solutions.
