Also known as: PAR2 block, source block
The unit PAR2 works in. Source files are divided into equal-sized blocks, and recovery data is computed across them so any block can be reconstructed from the others plus enough parity. Repair is arithmetic on whole blocks, not bytes, so one bad byte costs a full block. Smaller block sizes give finer-grained repair at the cost of larger PAR2 files and slower verification.
