QCon London 2026: Spritely: Infrastructure for the Future of the Internet
"When technology is centralized, life is good until investors look for their return on investment. As a result, services can degrade over time or possibly disappear. Users have no control over changes."
"A Centralized technology is a single source of truth, but is fragile and capturable. A Decentralized technology removes the central server that can yield resilience and user agency, but is more complex."
"Concurrency is hard because of deadlocks, shared state and order of messages. Synchronization is hard because of consensus algorithms, eventual consistency and fault tolerance. Infrastructure is hard because of the many tools available for a client/server network, but not for a peer-to-peer network because the industry is focused on the business needs of centralization."
Spritely addresses problems inherent in centralized internet infrastructure where services degrade when investors seek returns and users lose control. Centralized systems offer simplicity but lack resilience and user agency, while decentralized systems provide these benefits at the cost of increased complexity. Building distributed systems faces significant challenges including concurrency issues, synchronization difficulties, and inadequate peer-to-peer infrastructure tools. Developers must navigate legislative moats that protect centralized players while potentially excluding smaller competitors. Spritely proposes solutions through encryption, federation, and local-first software approaches, adopting a peer-to-peer network model with convention-over-configuration design philosophy to simplify development and empower users.
