Each node saves a complete ledger, and as long as there are enough nodes that recognize a record, it is considered valid. This decentralized structure makes it difficult for attackers to tamper with data because it requires a significant amount of computing resources to tamper with data on multiple  nodes simultaneously."}]}],"pr":"8e2a3f90e17617db393a7a977665a3040d79badd78344f5b93bd3c7381b89789"}
