- BSD licensed, patent-free source code
- up to 64000 source blocks and unlimited number of ECC blocks
- encoding and decoding speed of 300+ MB/s (measured on single core of 4GHz i7-4770 for 64000+64000 blocks)
- it works with binary data so no need to convert data to/from GF(p) field

- it's not MDS code, so with 0.1% probability it may require 1 extra ECC block to decode (and with even smaller probability it may need 2 or more extra blocks)

 Thank you for information. The implementation of Rateless Codes (Fountain Codes) is interesting. I will test it later. If it's possible to extend 32-bit base, it may defeat the superiority of RSC32. (Erasure Codes requires many small blocks to recover widely spreaded random error.)
