Which feature of Bitcoin is also applicable to all business blockchains?

Irrefutable proof of transactions is a fundamental characteristic of all blockchain systems, including Bitcoin and business-focused blockchains. This feature ensures that once a transaction is recorded on the blockchain, it cannot be altered or deleted, providing a permanent and verifiable record. This immutability is achieved through cryptographic hashing and consensus mechanisms that secure the integrity of the data.

In a business context, having irrefutable proof of transactions is vital as it enhances trust among parties and reduces the chances of fraud or disputes. Each transaction is linked to a previous transaction, creating a chain of trust that is transparent and auditable. This is particularly useful for industries that require meticulous record-keeping and accountability, such as finance and supply chain management.

This concept is not specific to Bitcoin alone but is integral to all blockchain technologies, reinforcing the reliability of the system in various applications.
