Log Periodic is an independent research and development lab working on protocols to improve the internet's resilience and efficiency.
- Range-Based Set Reconciliation is a method for synchronising data-sets. This article describes the theory behind RBSR and introduces Log Periodic's negentropy project.
- strfry is a C++ implementation of the nostr protocol, a distributed communication protocol that approximates CRDTs. strfry is designed to be highly efficient, and supports syncing of data-sets using the negentropy protocol.
- quadrable is an authenticated multi-version database. It is implemented as a sparse binary merkle tree with compact partial-tree proofs. There are C++ and Solidity libraries, as well as a git-like command-line tool.
- ephemerand: A globally-consistent randomness beacon that extracts unpredictable data from the GPS almanac.
