Pubky Aggregators

Aggregators collect and normalize social data from multiple Data Stores:

• Initial aggregation starts from a core user graph and expands outward through connections.

• Fine-grained access controls allow selective data sharing between users and aggregators.

• Merkle trees enable efficient synchronization of incremental changes from Stores.

• Normalized data schemas support interoperability between services.

• Public aggregators operate at scale for discoverability, while smaller niche aggregates also exist.

• Censorship resistance comes from distributing aggregation across independent operators.

• Microservices enable modular aggregation of different data types (profiles, posts, comments, etc).
