Hi,
currently there are on average 300 000 BTC transaction per day.
My question is : is it possible to keep 1 mb block (with technical solutions) while the transaction numbers per day increases to 1 million, 10 millions, 100 millions...?
thanks
It depends on where the transactions will take place. The plan is to move majority of transactions to offchain solutions such as lightning and sidechains. Even if then the bitcoin blockchain is not able to support the transactions, there will be a hard fork by developers to increase the block size.
