Blockchain technology is a distributed ledger that records transactions in a secure and transparent manner. It is a decentralized system, meaning that it operates without the need for a central authority or middleman, and instead relies on a network of computers to validate and process transactions.
In a blockchain network, transactions are grouped together in blocks, which are then cryptographically linked to each other in a linear, chronological chain. Each block contains a unique code, called a “hash,” that identifies it and links it to the previous block. This creates a secure, unalterable chain of blocks, or a blockchain.
The decentralized nature of blockchain technology makes it highly secure and resistant to tampering and fraud. There is no single point of control or failure, as the network is maintained by a distributed network of computers. If a malicious actor tries to alter a block in the chain, the changes will not be accepted by the rest of the network.
In addition to its security benefits, blockchain technology also provides transparency and immutability. All participants in the network have access to the same information, and once a block is added to the chain, the information it contains cannot be altered. This makes blockchain an ideal technology for various applications such as cryptocurrency transactions, supply chain management, and secure data sharing.
Overall, blockchain technology has the potential to revolutionize various industries by providing a secure and transparent way for parties to interact and transact without the need for intermediaries.

Whether it’s bringing transparency to a supply chain, reducing risk in financial transactions or defining ownership and value of so-called “non-fungible tokens,” or NFTs, blockchain is increasingly seen as much more than a Bitcoin database.
