An immutable contract refers to a type of agreement coded into a blockchain that cannot be altered or deleted once deployed. This characteristic stems from the inherent properties of blockchain technology, where data is cryptographically secured and distributed across multiple nodes.Once a smart contract is created, any changes require creating a new contract rather than modifying the existing one. This immutability ensures that the terms of the agreement remain enforceable and transparent, as all parties can verify the contract’s content on the blockchain.The immutability of these contracts plays a crucial role in establishing trust between parties. Since the contract’s code operates as the sole executor of the terms, it eliminates the need for intermediaries, reducing the risk of fraud or manipulation.In practice, immutable contracts are used for various applications, including financial agreements, supply chain management, and decentralized applications, providing a secure and reliable way to enforce commitments without the possibility of alteration.
