We should declare the initial set of OOB (Out-Of-the-Box) Iroha Special Instructions for Hyperledger Iroha 2.0.0 release.
Action items
- Nikita Puzankov define a list of initial ISIs
- 武宮誠 and Yuriy Vinogradov review it and add suggestions/comments
- Nikita Puzankov conduct the final meeting and write down agreement on the final set
Problem
Iroha whitepaper, current implementation and users' expectations are different in terms of out-of-the-box Iroha Special Instructions set.

- Register/Unregister

- Register or unregister Account in Domain
- Register or unregister Asset Definition in Domain
- Register or unregister Peer Id in Peer

- Mint or burn value to or from an Asset
Provide a set of tools for DeFi:
- Register DEX
- Register new DEX
- Register Liquidity Source
- Register XYK Pool
- Register Order Book
Alternatives
- Do not have categories and generic instructions using a plain set of instructions like "AddDomain, RegisterAccount" - as cons we can point out naming and extensibility problems
- Do not have granularity and differences between register, mint, add - as cons we can point out different business-related meanings for similar actions and to a wide set of options in one bucket
