Decentralization in blockchain refers to the distribution of power, control, and decision-making across a network of participants, rather than being concentrated in a single central authority. In a decentralized blockchain network, all participants have an equal say in verifying and validating transactions and maintaining the integrity of the network.
Blockchain
Blockchain is a decentralized, distributed ledger that records transactions across multiple computers in a secure and transparent way. It uses cryptography to ensure that once a block of data is recorded, it cannot be altered or deleted. This makes it suitable for applications such as digital currencies, supply chain management, and secure data sharing. The most famous blockchain is the one used by Bitcoin.
