Well mate, yung digital signatures, common sa mga decentralized systems tulad ng Bitcoin or Nostr. Ginagamit ito para i-verify na galing talaga sayo ang isang message o transaction.

Sa traditional social media platforms like Twitter, Facebook o TikTok, hindi sila gumagamit ng digital signatures in the same way. Sa kanila kasi, centralized yung system - meaning may main server na nagha-handle at nagve-verify ng lahat ng data.

Pero meron din silang security measures to verify users and protect data - tulad ng encryption at https certificates para sa secure connections. It's a different approach compared sa decentralized systems!
