 - started to think about what I am looking for in a base. I realised I still dont really know and that starting from a base might not actually help me to find that out. I need to identify issues with current systems, because to me it seems like I could almost just use an existing p- maybe not. I think I just need to write down a basic overview of what I want, then work out the details later.

+- I should look into some specific scenarios and how they might play out within existing closed blockchain systems. e.g.,
+	- kicking out one or more participants
+	- forking due to not trusting or agreeing with other participants
+	- what if one participant is a bad actor and the other want to remove them, but the bad actors vote is required
 - The idea of tethering a closed blockchain to a public blockchain is worth considering

+- Rather than acting directly as a source of truth, a blockchain as applied to the veracity project should act as a store of records that can then be used by relevant authorities make decisions – which can then be recorded on the chain
+- maybe consider something related to a reputation system like ebay (talk to andrew), trademe, etc
+- regarding scope: this is something I need to think about. Does it make sense to have a closed blockchain with 100s or 1000s of participants. This is somewhere where we would like have a small group of validator nodes and many less-priviledged participant nodes
+- my role is this project is exploratory. By considering many small scenarios, I might eventually find one which breaks the existing architectures and I can then work on a solution for that.
+- i should spend some time to try and get the prolog kernel working
+	- try rolling back to an earlier version
+- also test the aforementioned scenario using a small network of ~10 participants
