I have successfully downloaded, compiled and installed bitcoin-cli from github.
I can send or receive bitcoins with sendtoaddress and getnewaddress methods.
It works great and i am happy to do that without install third party software (i do not trust them)
But i have a problem: I need to download the full blockchain files (with bitcoind) on my computer.
Is there a way to run sendtoaddress and getnewaddress methods with having only wallet.dat file on my computer ? I do not want to download the full blockchain files. Is it possible ?
How works ledger wallet key ? This small key does not contain a copy of the blockchain. And it works !
