A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
How Does a Blockchain Work?
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
The block chain is shared between all Bitcoin users. It is used to verify the permanence of Bitcoin transactions and to prevent double spending. A transaction is only considered complete once it is included in a block. Once a transaction is included in a block, it is verified by the network and can never be altered or reversed.
The block chain is maintained by a network of Bitcoin users who all work together to verify and approve new transactions. Every ten minutes, on average, a new block is created and added to the block chain. This block contains a list of all the recent transactions that have not yet been approved.
Once a transaction is included in a block, it is considered to be confirmed. Confirmed transactions are permanent and cannot be reversed. Transactions can only be added to the block chain.
The block chain is public. Anybody can view the contents of the blockchain, but users can also opt to connect their computers to the network and help verify transactions.
