The characteristics you mentioned are some of the most important benefits of blockchain technology. Decentralization ensures that no single entity has control over the network, making it resistant to manipulation or attacks. Immutability ensures that the data recorded on the blockchain cannot be altered, providing a tamper-proof record of transactions and events. Transparency allows all participants to view and verify transactions, increasing accountability and trust. Security and efficiency are critical aspects of any financial system, and blockchain technology ensures both through the use of cryptographic algorithms and automated validation processes.
