Over the last decade blockchain platforms have attracted increasing interests; the maturation of the technology allowed it to develop from a peer-to-peer payment system originally inspired by the cypherpunk movement to a technology which today also finds applications in the industry. This evolution required an adaptation to fit with the needs of enterprise use, thus causing the transition from the permissionless paradigm of the original open blockchains to the permissioned one, more suited to the use case. However the technology is not yet ready for industrial massive scale deployments, since it presents some scalability problems due to the underlying Byzantine Fault Tolerant protocols used to reach consensus on the order of transactions, which hinder its adoption.
