I need some answers.
Please elaborate, this is a new technology and no one really know how byteball DAG works.
1) Who responsible for hardforks? Should witnesses vote on hardfork? Or it's only depends on developers and right repository?
2) Is there a way to prune old transactions from local database and build transactions on some fresh ones? Is it necessary to keep all DAG on a disk?
3) Is there a SPV  wallet? Is it possible to make SPV wallet?
4) Why 12 witnesses, not  1200? From technical point of view, not politics. Is every transaction should carry all witnesses list with it? So transactions will be bigger proportionally to list of witnesses? Or not, and there is no problem to do 1200, 12000 or 1200000 witnesses potentially?
5) Can witnesses change max supply of coins and generate 10000 tb more? If not, who can?
