# Tamper-Evident Logs and Data Integrity {% embed url="" %} The BSV Ledger provides a robust solution for maintaining data integrity through its **tamper-evident** logs. Once logs are written as transactions to the BSV Ledger, they **cannot be deleted or altered**. This characteristic is particularly important in scenarios where data integrity is paramount, such as in the case of logs that could reveal malicious activities. In many instances of **cyberattacks**, one of the first actions taken by attackers is to **delete logs that could provide insight into their activities**. By relying on trusted third parties to maintain these logs, organizations expose themselves to the risk of compromise. The BSV Ledger, being distributed across a peer-to-peer network, mitigates this risk by **eliminating single points of failure**. This results in an unalterable, verifiable record that ensures data integrity, even in the face of malicious attacks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
