Hi, @khrom,
I have doubts about how this number of days will be determined? Was it a vote of the witnesses or was it simply set until the next HF?
Nothing is determined yet. Fortunately, we have a live working system that we can check. Serey, and Whalshares currently use a similar system where if a witness is missing x blocks per 24 hours, the witness will be automatically disabled. If the witness wants to be back again, he will need to broadcast. This is like a kill switch script that some witnesses use to disable their nodes when they start missing blocks to avoid missing many blocks.
Regarding the justin sun example, no. He will not be able to recover the keys unless people want to recovery their accounts. Meaning, he can not, for example, start the recovery from his side and steal the account. Because he will need the keys of the account he is recovering.
It is simple, if you set @bob to recover your account, then you need to use your previous keys to recover your account when @bob starts the account recovery process. If you do not have a recovery account, then you can go e.g to @symbionts and ask them to initiate an account recovery for you. It just that if a user did not set a recovery account, he can reach a top witness that he trusts to recover his account.
Regarding burning assets, we do agree, but the thing needs to be discussed further. The prospective that someday someone can just wake up and dump millions in the market and extract all the value that was built by the community for years is not appealing to us.
The canonical signature is not really that important, since it is a technical improvement that is not going to directly affect the economy of the chain or the community. But surely, more information will be shared when the time comes.
Like how witnesses can set the price of Blurt accounts, more parameters can be added to allow witnesses to control more aspects of the chains. Said parameters are not yet defined and are subject to discussion.
Thank you for your reply,
