What is blockchain technology?

Learn more about blockchain technology. Blockchain is a digital ledger database whose recorded contents are encrypted into a sequence of blocks and distributed throughout a network of participating computers (nodes). Blockchain is a distributed ledger database system whose technologies can change the way businesses and governments operate.

What is a blockchain node?

Nodes in public blockchain networks are referred to as miners; they're typically paid for this task -- often in processes called proof of work or proof of stake -- usually in the form of cryptocurrency. A blockchain ledger consists of two types of records, individual transactions and blocks.

Can Blockchain Change industries from the bottom up?

Despite its reputation for impenetrability, the basic idea behind blockchain is pretty simple. And it has major potential to change industries from the bottom up. Blockchain is a technology that enables the secure sharing of information. Data, obviously, is stored in a database. Transactions are recorded in an account book called a ledger.

What is blockchain decentralization?

Blockchain decentralization is one of the fundamental aspects of the technology. Unlike centralized databases where a central authority, such as a bank, controls and verifies transactions, blockchain operates on a distributed ledger. This means multiple transparent participants, known as nodes, maintain, verify and update the ledger.
