This avoids single-point failures and security risks associated with centralized exchanges. Additionally, blockchain technology possesses immutable characteristics that ensure the authenticity and integrity of transaction records. Furthermore, digital wallets, serving as the fundamental unit of cryptocurrency transactions, primarily ensure security through aspects such as decentralization, private key protection, and resistance to attacks. Blockchain technology also employs various security measures, including encryption algorithms, multi-signature technology, and smart contracts, to enhance transaction security. In summary, blockchain technology achieves decentralization and distributed ledger technology to safeguard against failures and security risks associated with centralized exchanges."}]}],"pr":"086bb780895f1262b607e9e768334ffb82037cd9a352d3a2f365b65f07f8852d"}
