This comprehensive guide provides an in-depth look at the IBM Blockchain Platform, a powerful and secure platform that enables organizations to build, govern, and operate blockchain networks. It covers the fundamentals of blockchain technology, the features of the IBM Blockchain Platform, and how to get started
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Since each block contains information about the previous block, they effectively form a chain, with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the data in any given block cannot be changed retroactively without altering all subsequent blocks and obtaining network consensus to accept these changes.
