Waku Store Architecture: Designing for Peer-to-Peer Offline Retrieval
Explore the architecture of Waku Store, a P2P persistence layer that enables offline message retrieval using local KV stores and cryptographic verification.
wakuSpam Without a Moderator: How Waku's RLN Relay Rate-Limits a Permissionless Network
Waku's RLN Relay uses zero-knowledge rate-limiting nullifiers to stop spam in a permissionless pub/sub network — exceeding your message rate exposes your own secret key. Here's how it works and what it costs.
Message Delivery Order Inconsistency in Waku Gossip Protocol
Gossip Propagation and Sequencing Waku employs a decentralized gossip-based protocol to propagate messages across a peer-to-peer network. While the store-and-forward mechanism ensures that offline peers can eventually retrieve missed data, the protocol does not natively guarantee a global deterministic order for message arrival across varying network topolog
