When you start using the same private key to sign multiple transactions, isn't a security issue over time? Wouldn't be safer of they provided a zpub since the zpriv has more entropy?
Discussion
Can you expand on this? How is zpub different/better?
I meant by providing a zpub, it would still have been easy to verify the holdings, and for them to avoid signing multiple transactions using the private key for the same address. However nostr:npub1qny3tkh0acurzla8x3zy4nhrjz5zd8l9sy9jys09umwng00manysew95gx mentioned that they would change private key and address every time any outflow occurs, so the security concern I had does not really hold anymore.
