This document discusses information security in blockchain technology. It provides background on blockchain, explaining how it evolved from distributed database concepts in the 1990s to Bitcoin in 2008. Blockchain uses cryptography, software, and networks to securely store data in a decentralized, distributed manner. This allows it to provide improvements to information security like confidentiality, integrity, availability, non-repudiation, authenticity, and accountability. The document concludes by stating that blockchain is the future of the internet.
