Blockchain technology falls into two distinct classes: open (permissionless) blockchains such as those underlying bitcoin, Ethereum and Cardano; and closed (permissioned) blockchains such as implemented in the Hyperledger Fabric project. To motivate decentralised participation, open blockchains (presently) require an associated cryptocurrency, which can be a risky distraction. However, closed blockchains are considered by some to be insufficiently decentralised.This summer project aims to prototype a compromise: a closed blockchain system that encodes voting rules about self-governance, so that closed blockchain technology can be used in a more open manner. Experience in programming blockchain systems is not assumed. Depending on the student involved, the project will balance work between design and modelling of the blockchain governance rules, and implementation of such a rule set over an existing closed blockchain system.

- what actually is hyperledger fabric? Is it a closed blockchain that different groups can run independently for their own use-case?

Is it a closed blockchain that different groups can run independently for their own use-case? Or is it one single closed blockchain that many different groups participate in.
- hyperledger fabric is one of the projects created by hyperledger. It is a framework/base from which the community can develop their own blockchains.
- [ ] is governance within a closed blockchain the same as within an open blockchain
- [ ] why would a participant want to fork?
- [ ] does the central authority e.g., govt decide who can join and leave?
- [ ] It the code developed by the central authority or spread across partipants?

where to start? pretty overwhelmed with this whole blockchain thing. Not really sure where this project is going. At the moment what I understand is that I'm looking to a more open version of a closed blockchain. One which is initiated by a central authority e.g., the government, who then allows other parties to join. In the example with the organic supply wh- would each company who wanted to verify that their produce is organic, "join" a central blockchain. From the beginning of the (supply) chain to the end there are many different companies involved. So would the journey of the item be tracked on a blockchain? Maybe not neccessarily the journey but maybe throughout its route, each thing (or an agreement to provide that thing) that is need to prove an item's "organicness" is added to the chain, then when it reaches the end the chain is discarded? Surely that's not right. Does a blockchain necessarily need to represent a *sequence*? Yeah I think so. But a currency like bitcoin is an infinite sequence, whereas an items journey is finite.

so is it a closed blockchain with a set number of participants (or a set of requirements for participants?) who can join (what does join mean in this context) and leave at will. How are all the different companies on the same blockchain. How do smart contract fit into all this? Is sequence relevant in a closed blockchain or is it just like a regular but distributed database? so is it a closed blockchain with a set number of participants (or a set of requirements for participants?) who can join (what does join mean in this context) and leave at will.

Initiated by central authority like the govt. Then compies who want to verify that they are an organic producer ask to join the network so they can add the required documents (or pointers to the documents) to the chain. These documents are now viewable by governing authorities (perhaps internationally). If necessary, various parties involved in the supply chain can also
