Hi.

thanks for your mail.

could you switch document mode you attached
to allowing comments?

here some questions

how to cover or handle private chains?
many groups are trying to handle blockchain privately with reduced
difficulties.
even some private chains has very low trust than the public chains.
actually can not define it is blockchain.
who and how define chainID?

some groups are not trying to load data on OP_RETURN script to reduce or
postpone the tx fee to consumer side(meaning putting data on input script).
who and how define anchor type?

regards
mountie.
