Immutability is the ability of blockchain technology to ensure past transaction data cannot be changed. This means that Bitcoin or other crypto asset transactions are permanently recorded and visible to everyone, making it impossible for any entity to change, replace, or falsify data stored in the blockchain.
Blockchains’ immutability can help to improve the present trust and auditing system. It can save time and money on audits by making information verification considerably easier or even unnecessary.
It can also help many businesses improve their overall efficiency by allowing them to keep a complete historical record of their business activities.
