Of course, the bitcoin blockchain cannot change its genesis block, which the newly developed blockchains can do, but it can always include special blocks that certify the code authorized to modify it.
This would be the softest but still valid solution.
I don't understand why a special block, why not just verify a cryptographic function on the code before running it?
There was a violation of rules, repeatedly.
Honestly, the fact that I couldn't find the paper elsewhere, the medium link doesn't work, the one person acting as if a lawyer to the author hardly posts very small parts, not a name/twitter/....etc
All of these make me suspecious.
If one has a different point of view, one must allow the expression and full development of that point of view.
Express it & discuss it yes, but a full development I'm not sure; at least not on the publicly used software ... you don't run trial experiments on people or their savings.
As an example, my idea about UTXOS categorization/partition ( their Merkle as a start) although best suited to be tested on Utreexo, but I can not force them too.
Yes I expected them to do it or at least discuss with me why don't they think it's promising, but for the sake of scientific research or achieving more improvement; not for me as a person.
Like I'm discussing here without knowing this SMZ or even anyone of you.
