A common authoritative record of transactions, and the data that describes those transactions, is fundamental to all business interactions. Traditionally the data, and the state of the data, has been maintained in databases and ledgers controlled by companies or governments who rely on auditors, trusted third parties and the legal enforceability of contracts to support confidence in transactional interactions and the related business velocity.聽

Blockchain makes data, transaction records, and the business logic that can manipulate the data a fundamental characteristic of a decentralized network. This is a revolutionary capability.

Blockchain is the foundational technology for the Web3 era. It is the database and operating system of the networked economy. As the world鈥檚 businesses and governments continue to digitize, their systems will run on blockchain.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

• The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.

• The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
