  • Published 2016
Present-day blockchain architectures all suffer from a number of issues not least practical means of extensibility and scalability. We believe this stems from tying two very important parts of the consensus architecture, namely canonicality and validity, too closely together. This paper introduces an architecture, the heterogeneous multi-chain, which fundamentally sets the two apart. In compartmentalising these two parts, and by keeping the overall functionality provided to an absolute minimum… Expand
