Blockchain courses

A blockchain is a permanent, sequential list of transaction records distributed over a network. Each block in the chain contains a hash of the previous block, along with a timestamp and transaction data. This makes the blockchain inherently resistant to attack or manipulation.

Blockchain technology is ideal for recording various types of transactions where data is sensitive or targeted by hackers for unauthorized duplication or other fraudulent activity. Bitcoin and other cryptocurrencies use blockchain technology to record transactions. Blockchain for business applications can include recording of contracts, medical records, monetary transactions and much more.

Cryptography is the study and practice of securing private messages so that they can only be read by the intended parties. It involves encrypting and decrypting content using various methods and encryption keys. An unintended third party would not be able to understand the message without the proper key to decode it. Modern cryptography has grown to include many sub-fields of study such as data integrity and user authentication and is vital to ecommerce, banking and much more.
