A blockchain is a collection of data records, or "blocks," that are linked through using secure cryptographic hashes to form a "chain" that can be read and verified easily by anyone with the correct credentials but cannot be altered. This system is perfect for supply chains, health records, and other sensitive data where security and transparency are critical.
Blockchain in Action introduces the fundamental principles of the blockchain and teaches you to build secure applications that can be used for voting, private auctions, and electronic record management.
