diffrence between wallet address and public key of a node

Question

what is the diffrence between the allet adress and the public key of a node, i thought that it is the same thing, how can i get them in order to verify the differnce

Answer 1

Formally, an address is calculated from a public key, and the public key itself is only revealed on the blockchain when a transaction is signed. But in practical terms, an address fulfills the role of a public key as is familiar from other cryptography schemes. See APIs like validateaddress to see the differences.
