When I create a bootnode, I am not getting the enode. So I used this link for reference to derive it. However, the below is happening. It seems that the bootnode address is 128 bits whereas it is expecting 256.

Any idea what I'm doing wrong?enter image description here

You are doing it right but the third command you are running is useless.

bootnode -nodekey boot.key -writeaddress

will print your bootnode enode, and you can then get the enode url using :


The param -nodekeyhex as to be used instead of -nodekey if you generated a hexadecimal boot key.
