# 5/12

Week Review
- Got the prolog notebook to work. 
- Read some interesting papers, tethering to public chain, reciprocal hyribd on/off chain governance
- thought about some scenarios
	- kick out participant
	- add new participant
	- mistakently add senstitive data to chain
	- one participant finds a security bug

This week
- try to implement some scenarios with a demo network
	- add new participant: off-chain or on-chain voting? Should store some record of vote outcome on-chain
- consider more scenarios
- read more papers

More about adding new member
- Existing members vote to add new member
- on or off chain vote?
- store record of vote outcome on-chain
- consider special cases
	- details of vote cutoff time
	- parameters of vote change during vote
- hyperledger
	- The purpose of add peer command is to write into ledger the fact of peer addition into the peer network. After a transaction with AddPeer has been committed, consensus and synchronization components will start using it.
	- transaction to remove peer requires the node making the transaction to have the can-remove-peer permission
	- can nodes with this perssion remove peers at will?
	- not 1:1 nodes:accounts
	- with HL Burrow you can use Solidity smart-contracts on Iroha
	- iroha would either have to be off-chain voting then a trusted peer (or initial) would add them
	- or: will need to look into HL Burrow but there might a way to have an on-chain smart contract voting system which automatically adds them depending on the vote
		- I could think about how to implement such a smart contract

# 6/12

yesterday
- didn't get a lot done
- trying to get notebook to work with pyswip 0.2.10
- some thoughts about adding a new person to the chain
	- looked at how to do it within hyperledger
	- one existing peer needs permission to add another peer

what about removing a person from the chain?
- within hyperledger. 

should i be using iroha2 - much better docs, newer version.

https://github.com/hyperledger/iroha/blob/iroha2-dev/docs/source/iroha_2_whitepaper.md

Im going to try to add a fifth peer to the four node demo network while its running
