  Immutability in cryptocurrency transactions is achieved through the use of blockchain technology. When a transaction is made, it is recorded on a block, which is then added to the blockchain. Each block contains a unique cryptographic hash that is generated based on the data in the block. This hash is used to link the blocks together, creating a chain of blocks. Once a block is added to the blockchain, it cannot be altered or removed without the consensus of the network. This ensures that the transaction history is secure and tamper-proof. The decentralized nature of cryptocurrencies also contributes to immutability, as multiple copies of the blockchain are maintained by different nodes in the network, making it difficult for any single entity to manipulate the data.

  Cryptocurrency transactions achieve immutability by utilizing cryptographic algorithms and decentralized networks. When a transaction is initiated, it is broadcasted to the network and verified by multiple nodes through a process called mining. Miners compete to solve complex mathematical problems, and the first miner to solve the problem adds a new block to the blockchain. This block contains a record of the transaction, along with a hash that is generated based on the previous block's hash and the transaction data. The hash serves as a unique identifier for the block and ensures that any changes to the transaction or the previous blocks will result in a different hash. As a result, once a block is added to the blockchain, it becomes nearly impossible to alter or delete the transaction without the consensus of the network.

  Immutability in cryptocurrency transactions is achieved through the use of decentralized consensus mechanisms. When a transaction is initiated, it is broadcasted to the network and validated by multiple nodes. These nodes use consensus algorithms, such as Proof of Work or Proof of Stake, to agree on the validity of the transaction and add it to the blockchain. Once a transaction is added to the blockchain, it becomes a permanent and unchangeable record. The decentralized nature of cryptocurrency networks ensures that no single entity has control over the transaction history, making it difficult for anyone to alter or manipulate the data. This immutability is a key feature of cryptocurrencies, as it provides transparency and security to users.
