We know that all bitcoin transactions will be recorded in the ledger and the data will get bigger day by day, is it logical if the recording has reached 100 or 200 years, and how big will the bitcoin ledger data be in the future?
The blockchain size has just gotten over 500gb and this is 15 years down the line. Majority of nodes can use a 2tb or 4tb hard drive which doesn't cost much and be able to store all block data till the foreseeable future.
Can bitcoin transactions be accelerated in the future? I think Bitcoin needs to accelerate with increasingly sophisticated technological developments, and transaction speed will probably become a vital need in the future
Some changes can be made at the protocol level depending on how the adoption of Bitcoin changes.
