Or users who forget their private keys can permanently lose access to their assets, as there is no central ownership register. Records of ownership of digital assets are held securely on a type of decentralised database, or electronic ledger, called a blockchain, which is distributed among its users.

• At the very beginning when Satoshi Nakamoto invented the technology he named his blockchain as Bitcoin.
• Timing would be everything in this type of attack—by the time the hacker takes any action, the network is likely to have moved past the blocks they were trying to alter.
