Definition ∞ Rateless Erasure Codes are a type of forward error correction code that can generate an arbitrarily large number of encoding symbols from a fixed set of source data. This allows a receiver to recover the original data as long as they receive a sufficient number of these encoding symbols, without knowing the exact number beforehand. They are highly efficient for data transmission and storage in unreliable environments.
Context ∞ In blockchain technology, rateless erasure codes are highly relevant for improving data availability layers, especially in scalable architectures like sharding or data availability committees. They enable network participants to reconstruct necessary data even if a significant portion is lost or withheld, enhancing the robustness and decentralization of data storage. Research efforts focus on optimizing their implementation for efficient use in decentralized networks.
