The decentralized feature  means that no central institution can control data storage and transactions, reducing the risk of single points of failure. The tamper-proof feature ensures that the data stored on the blockchain is genuine and reliable, as each block depends on the hash value of the previous block. Once the data changes, the entire blockchain data will change, which is almost impossible. Anonymity ensures that both parties in a transaction can conduct transactions while protecting privacy, reducing the risk of online fraud."}]}],"pr":"85cfc0540b4b90286dc07bf92521ec973124a1c2afcdde1252eb21b3bc5151ec"}
