Data Redundancy

Definition ∞ Data redundancy involves storing the same piece of information in multiple locations within a system. This practice ensures data availability and integrity, serving as a safeguard against data loss due to hardware failures or system corruption. In blockchain contexts, redundancy is a fundamental characteristic, as every full node stores a complete copy of the ledger. This distributed replication significantly enhances the network’s resilience and fault tolerance.
Context ∞ Data redundancy is a core tenet of blockchain technology, ensuring the integrity and persistence of transaction records. News reports often mention it when discussing network security and resistance to censorship. While beneficial for data preservation, excessive redundancy can present scalability challenges for large networks. Future optimizations aim to balance the benefits of data replication with more efficient storage solutions.
