I am reading "Mastering Bitcoin" written by Andreas and I found this explanation about "WIF(Wallet Import Format)"
Both private and public keys can be represented in a number of different formats. These representations all encode the same number, even though they look different. These formats are primarily used to make it easy for people to read and transcribe keys without introducing errors.
I have two questions:
I agree with that a private key as decimal numbers is not easy to use for people. However, the hex format and WIF are very similar. I think that WIF has two advantages compared to hex. One is starting with 5 and the next one is having checksum. Are there any good points of WIF.
Can I sign on a transaction by using WIF without the private key?
I'm keen to know about inside bitcoin. Any information will be helpful for me.
