No, Banks dont need to adopt the blockchain technology because this will make the bank accounts anonymous. How about the government accounts ? What will happen to them ? How to know if this government officials are corrupting the country ? We need to know all the transactions of all the banks in a country and we need to know whos can be punished or not. And bitcoin will always be anonymous no matter what.
The blockchain does not make the banks account anonymous. The banks can correlate the account and user.
Lol this exactly. Is your account number 1234567 anonymous right now? Nope. Neither is your bitcoin address. If you don't know who is behind the address it's still not anonymous as you can follow the transactions. Anonymous would be people passing around a paper wallet and never actually spending it on the blockchain.
Or physical bitcoins (essentially the same thing as a paper wallet). Alternatively, if coinjoin and other privacy-enhancing measures take off, bitcoin's anonymity/pseudonymity could be improved much further.
