Will blockchain survive as a transfer of value mechanism?
I think most blinders would agree that cryptocurrencies don't seem to have a future. The next most cited utility is, blockchain as a medium of transfer of value for real world assets via tokenization: fiat money, stocks etc. Do you think this use case has a future? For e.g. we have venmo, zelle etc which work fine without a blockchain.
Some of the above
If transaction speed improves massively, then maybe. Could survive as a fringe thing.
Block chain basically is serving where there is risk a back will not. This if course includes lots of black market stuff but there is plenty of legal crap banks won't do because it's risky. Eg, try sending money to a foreign account, transfer more than 10k per day, ...
I think this is spot on. And if it is too risky for banks to want to handle it... well... building a business out of it at scale will probably fail.
By the very design it will never be a speedy transaction. You need more than 50% of the network to record a transaction
50% of the network what?
Try to build few simple smart contracts. You'll see how vast this field is. Of course, we are still in the infancy stage of Blockchain. I'm biased.
Still have no clue wtf blockchain is
