## Pubky Protocols This note is indicative and highly creative. We have not yet explored much about the open protocols that enable independent implementations: **Pubky Data** - Definition of normalized data schemas for user profiles, content types, relationships etc. Allows unified querying across services. **Pubky Sync** - Mechanism for efficiently synchronizing incremental changes between data stores, aggregators, and consumers using Merkle trees. **Pubky Search** - Format for full-text search indices and queries across aggregated Pubky Data. Enables cross-platform discovery. **[Pubky Payments](Paykit.md)** - Decentralized and interoperable payment protocol for microtransactions like tips, subscriptions and purchasing goods/services. **Pubky Identity** - Self-sovereign digital credentials for authentication without centralized authorities like usernames/passwords. **Pubky Federation** - Standard for distributed moderation and cross-instance relationships between interconnected but independent communities.
