I am new to Bitcoin and Blockchain and I am writing a thesis for my university about this topic.
I have a general question about digital signatures, which are needed to verify a transaction.
As far as I understood, for having a digital signature, one need to have a public verification key and a secret key.
Is the secret key equal to the private key which is needed to spend transactions.
Analog: Is the public verification key the same as the public key whose hash is the bitcoin adress ?
Thank you in advance.
