Blockchain technology is most com1(707)⇄767⇄3703 monly associated with cryptocurrencies (like Bitcoin and Ethereum), but it has many potential applications in industries like finance, supply chain, healthcare, voting, and identity management.Once data is added to a blockchain, it is i1(707)⇄767⇄3703 mmutable, meaning it cannot be changed or deleted. This is achieved through cryptographic hashing and consensus mechanisms. To alter a single block, an attacker would need to change all subsequent blocks, which is computationally infeasible due to the cryptographic techniques involved.1(707)⇄767⇄3703
