Bitcoin is decentralized

 - Bitcoin does not have a central authority.
 - There is no central server; the bitcoin network is peer-to-peer.
 - There is no central storage; the bitcoin ledger is distributed.
 - The ledger is public; anybody can store it on their computer.
 - There is no single administrator, the ledger is maintained by a network of equally privileged miners.
 - Anybody can become a miner.
 - The additions to the ledger are maintained through competition. Until a new block is added to the ledger, it is not known which miner will create the block.
 - The issuance of bitcoins is decentralized. They are issued as a reward for the creation of a new block.
 - Anybody can create a new bitcoin address (a bitcoin counterpart of a bank account) without needing any approval.
 - Anybody can send a transaction to the network without needing any approval; the network merely confirms that the transaction is legitimate.
