This document provides an outline and overview of blockchain technology. It discusses the evolution of blockchain, how it works by combining cryptographic keys, a peer-to-peer network, and transaction records. It also covers different types of blockchains like public and private blockchains. Applications discussed include supply chain management, cybersecurity, and voting. Pros of blockchain are also summarized like improved accuracy, reduced costs, and transparency.

3. Blockchain Technology
Blockchain is a combination of three leading technologies:
• Cryptographic keys
• A peer-to-peer network containing a shared ledger
• A means of computing, to store the transactions and
records of the network

10. Pros of Blockchain
• Improved accuracy by removing human
involvement in verification
• Cost reductions by eliminating third-party
verification
• Decentralization makes it harder to tamper with
