Definition ∞ Erasure coding efficiency refers to the effectiveness of a data redundancy technique in protecting information against data loss while minimizing the amount of redundant data added. This method breaks data into fragments and adds parity pieces, allowing the original data to be reconstructed even if some fragments are lost. High efficiency means robust data recovery with minimal storage overhead.
Context ∞ In blockchain data availability layers, erasure coding efficiency is crucial for optimizing the storage and retrieval of transactional data, especially for rollups and other scaling solutions. The ongoing discussion centers on developing erasure coding schemes that balance strong data availability guarantees with reduced computational and storage costs for network participants. Improved efficiency is vital for the long-term sustainability of decentralized storage.
