- Blockchain is decentralized, the information entered is irreversible.
- Blocks of data are linked together to form a blockchain, which is unlike a typical database. Fresh blocks are created when new data comes in. Data chains are created after data has been filled in the previous block.
- The blockchain can be used to store many types of information, but it is mainly use for transactional
ledger. - Blockchain is used in Bitcoin in a decentralized way, ensuring that no one user has full control.
- Transactions for Bitcoin are recorded permanently, so anyone can see them.

According to Forbes
- The Blockchain is a public ledger that records (providing ownership and time stamp) and validates every transaction made worldwide.
- What makes this network unique and secure is that all transactions are authorized and backed by thousands of computers (called miners), achieving consensus on each transaction.
- No one owns it (hence the term “decentralized”), and therefore it’s immutable and there’s no single point of attack for those attempting to “hack” or otherwise alter the records on the Blockchain registry.
- The technology enables peer to peer (P2P) transaction capabilities without any involvement of a central authority or a third party.
