BU doesn't work. It sounds good in practice, "wow automatically adjusted blockchain? just what we need" but in practice it opens a can of worms. Too many possible attack vectors.
If it was as easy I would support a dynamic blocksize, I don't because there are big tradeoffs by doing so that I don't want to deal with. I want to be able to find my bitcoin on my wallet 20 years from now. BU does not give me that peace of mind. They will fuck up hard.
do you even understand bitcoin or consensus.
you do know funds are locked to private keys.
an orphan/reject cannot steal your funds.
but blockstreams future feature mimble wimble can.
its worth reading and learning
but start at the basics of consensus vs bilateral.
as thats what im seeing most r/bitcoin script readers and blocksteam king defenders are mainly not understanding. plus it doesnt take years to learn. so theres no excuse to not spend just 30 minutes learning about consensus(majority agreement stay together) vs bilateral(walk in separate direction splits)
