In FAR-EDGE, the value of DLT is in distributed consensus: enabling the intelligent edge nodes of a system to agree - or disagree - on state transitions, to the effect that any change in global state (e.g., the assignment of a task to a specific node) must be approved collectively; moreover, individual nodes may fail or go offline without compromising the system as a whole. However, standard DLT platforms also maintain an immutable log of transactions (the Blockchain) that is replicated on all nodes, which may represent a significant performance bottleneck in many real-world applications. What we learned from the FAR-EDGE experimentation is that, in most factory automation scenarios, the historical memory of any transaction may be cleared once consensus is safely reached on it - something that is not supported by any current DLT implementation. This form of short-lived state persistency is something that is probably worth experimenting with in the future.
