Superspace: Scaling Bitcoin Beyond SegWit

Abstract. SegWit, or Segregated Witness, a soft fork successfully activated mid-2017 on Bitcoin blockchain, provided among other benefits a backward-compatible increase to the block size limit, all while not introducing consensus breaking changes to Bitcoin protocol and not resulting in a hard fork network partitioning. The potential space increase is estimated at being close to 2 MB total for practical purposes. In this paper, the author argues that it is possible, using the same mechanism, increase the block size further up to any agreed-upon limit, while still providing the same security guarantees SegWit does.
