What is Blockchain?

blockchain, technology, smart contract

Blockchain is a decentralized digital ledger that records transactions across a network of computers. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency.

Each block in the chain contains a number of transactions, and every time a new transaction is added it is grouped together with other transactions into a block. Once a block is added to the chain, the information in it cannot be altered, making the technology highly secure and resistant to tampering.

Blockchain technology is primarily used as the underlying technology behind cryptocurrencies, such as Bitcoin and Ethereum, but it has many other potential uses. It has the potential to revolutionize industries by providing a secure and transparent way to store and transfer data without the need for a central authority.

In summary, blockchain is a secure, decentralized and transparent technology that can be used to record transactions across a network of computers.
