This deliverable consists of the implementation of a distributed ledger technology (DLT) that integrates with DECODE technologies, more specifically with the Zencode smart-rules language and consequently with the Zenroom virtual machine (VM) that executes them. Zencode is a simple, non-touring complete, natural language interpreter based on a domain specific language (DSL) that can run and execute these transformations inside a very portable virtual machine (Zenroom) capable of cryptographic transformations (Roio, 2017). As of today Zenroom has been successfully adopted as a core component by every DECODE pilot.
