What Is Decentralization in Blockchain?
One of the most important concepts in blockchain technology is decentralization. No one computer or organization can own the chain. Instead, it is a distributed ledger via the nodes connected to the chain. Blockchain nodes can be any kind of electronic device that maintains copies of the chain and keeps the network functioning.

Every node has its own copy of the blockchain and the network must algorithmically approve any newly mined block for the chain to be updated, trusted and verified. Since blockchains are transparent, every action in the ledger can be easily checked and viewed, creating inherent blockchain security. Each participant is given a unique alphanumeric identification number that shows their transactions.

Combining public information with a system of checks-and-balances helps the blockchain maintain integrity and creates trust among users. Essentially, blockchains can be thought of as the scalability of trust via technology.

HOW BLOCKCHAIN WORKS
The blockchain is a digital database, composed of encrypted blocks of data which are "chained" together and secured by complex math problems
The math problems involving matching nonces and hashes is almost impossible to change later — the record of previous actions on the blockchain is highly accurate and secure from manipulation.
The blockchain is distributed identically across different decentralized nodes, ensuring no one organization can own or manipulate it.
