[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,
Or you could just take more caution and double check, or triple check that address you are sending to.
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.
For example
imagine having billion dollars transaction mistakenly sent to a wrong address where there is no system in place to reverse it.
• Firstly, Bitcoin is pseudo anonymous, soamy individuals would not want to have amy sort of unique name associated with their address.
• Having a system that can access and reverse erroneous transactions is same as centralization, which is the opposite of how Bitcoin was designed. You are essentially your own bank and are responsible for your actions and mistakes.
.High Transaction Fees.
More system should be created to help cut down the transaction fees incurred when during a transaction so that someone can pay almost zero in the transaction fees.
There are a couple of options to reduce tx fees
• Segwit addresses,
• Consolidating multiple inputs,
• Timing when you spend to avoid network clog,
• Calculating how much to spend, to prevent change address, etc.
