 ## What is PDU?
 
-PDU is a fully peer-to-peer (P2P) social networking system designed to enable participants to freely publish and efficiently access information without relying on any third-party services. Traditional systems that do not use centralized verification methods, such as phone numbers, are vulnerable to Sybil attacks, where the cost-free creation of new accounts can overwhelm the network with spam, undermining reward and punishment mechanisms. PDU addresses this issue by establishing trusted publisher identities through a sequence of messages signed by the same private key. Interactions such as reposts, comments, and likes create associations between publishers, allowing participants to form a custom set of visible publisher identities. This relatively stable scope enables an identity-based reward and punishment mechanism to effectively filter information.
