Onchain Data Immutable Security

Definition

Onchain data immutable security refers to the inherent property of blockchain networks where data, once recorded and confirmed, cannot be altered or deleted. This principle ensures that all transactional and state information stored directly on the distributed ledger remains historically accurate and tamper-proof. It is a foundational characteristic providing transparency and trust in decentralized financial systems. This immutability is critical for auditability and verifiable record-keeping.
