 # Remove Member
-What happens if one participant turned bad and the other wanted to remove them from the group. Ssay we havea grup of 10 participants in a closed blockchain system using a CFT consensus algorithm Then they can be voted out so that their vote is desregarded and so they cant view or access data on the chain. what if they require access to decuments stored on-chain which they dont have local copies of. I guess they wuld have access to a stored copy of the blockchain on their node. But then would this chain be considered valid by oters. they dont store the actual document on the blockchain – only a timestamped hash to prove they had that doc at this particular time. participats should keep local copies of documents. Can participants kick out the initiating authority? You would have some mechanism to ensure that they cant be kicked out. firstly there would have to be a vote to kick them out. unless they aren't actually needed. who are the people that look at the documents to check them. Some third party collectively employed by the group? the govt? maybe its required for each participant to sometimes go and check if other participants are being truthful.

 If someone uploads a document by accident that is sensitive, then the chain hard forks to remove it from the history, is it still publicly available (to the members of chain) or is the old fork erased. bu then what if someone stored a local copy (which they do). maybe the local copy is stored encrypted and the owner of the document has the key to unlock it.

 # Discovery of Security Vulnerability
 what if someone found a security vulnerability in the code. would they exploit it? how to change the code. would there be a different process to normal code changes for something critical like this. within the blockchain wallets/accounts are linked to a real world identity. but i guess the person who found the vulnerability could easily (note the "person" is a member of an organisation who has access to the code) tell someone else who is not identifiable and have them exploit the vulnerability. how do organisations decide who has access to the code. if the person does not decide to try to exploit it, they have to bring it to the attention of others or try to fix it themselves.
