[A]. Bitcoin transaction (Blockchain technology) in my view should be improved in such a way ,
That modifications can be to either where a wrongly sent transaction could be reversed when sent to a wrong address,
It would break Immutability property on Bitcoin.
The system could be improved in such a way that a unique name be attached to a partular address and anonymously the system would detect immediately that the name and address do not tally and hence tag it a wrong address, A system where this mistakenly sent transaction can be reversed if requirements for such reversal are met should also be created.
It encourage address reuse and add bloat to Bitcoin blockchain. It's also vulnerable to thief who register similar name.
What's your Good Ideas to solving Bitcoin transaction Issues let's discuss.
TLDR, encourage people to use LN and increase block size.
