# reed-solomon encoding

- form of error correction codes that detect and correct errors in data transmission or storage
- redudant data is add (parity bits) to the original data in such a way that if part of the data is lost or corrupted, it can be reconstructed
- from the idea that polynomials over finite fields represent data
- erasure encoding is the general form of it
- at large enough scale, rather than purely replicating for data integrity, usage of reed-solomon codes is better.
