1. Can you find getnewaddress and getbalance in the list? Does the description fir what the commands do?

  • Getnewaddress ``

PS D:\Bitcoin\daemon> ./bitcoin-cli -regtest getnewaddress

2NAVuu8czLuMhTzipsb5aJyQJXiuBA3RrzQ

Returns a new bitcoin address for receiving payments. If [account] is specified payments received with the address will be credited to [account].

Getbalance ``

PS D:\Bitcoin\daemon> ./bitcoin-cli -regtest getbalance

8824.99528020 ``

If [account] is not specified, returns the server’s total available balance.
If [account] is specified, returns the balance in the account.

2.Try to execute dumpwallet in order to store keys in a file.

NB; for reference if you have already dumped the wallet and get this error message it’s because you already have the file name for the dump (correct example below)

PS D:\Bitcoin\daemon> ./bitcoin-cli -regtest dumpwallet “test”

error code: -8

error message:

D:\Bitcoin\daemon\test already exists. If you are sure this is what you want, move it out of the way first

CORRECT EXAMPLE; PS D:\Bitcoin\daemon> ./bitcoin-cli -regtest dumpwallet “test”

{

“filename”: “D:\Bitcoin\daemon\test”

Which produces a file as above that you go click on the file open it with word pad for instance and you will get something like this:

Wallet dump created by Bitcoin v0.17.1

* Created on 2023-03-01T12:55:55Z
