Foundations of P2P Databases with Hyperkv and Hyperlog-Sodium

Building decentralized applications requires a solid understanding of peer-to-peer data storage and robust cryptographic security. This text-only course introduces you to the core concepts of Hyperlog, Hyperkv, and cryptographic signing using Sodium. You will transition from understanding basic database concepts to designing secure, distributed key-value stores. Through detailed written explanations and clear code examples, you will learn how to structure peer-to-peer data as a materialized view and secure it with public-key cryptography. What you'll learn: • Understand the fundamentals of distributed logs, peer-to-peer architectures, and LevelDB storage. • Configure Hyperkv to establish a decentralized key-value store over a Hyperlog materialized view. • Apply cryptographic signing using hyperlog-sodium to verify data integrity and author identity. • Implement secure peer-to-peer replication patterns without relying on central authorities. • Practice designing local-first data structures that remain resilient and consistent across nodes. The course starts with foundational definitions of peer-to-peer networking and distributed logs before moving into hands-on configuration of Hyperkv and cryptographic signing with Sodium. This course is designed for beginning developers and software enthusiasts curious about decentralized technology, with no prior cryptography or P2P experience required.
