    Linera Protocol

    Linera Protocol

    Main repository for the Linera protocol

    Linera Protocol is a blockchain or distributed ledger architecture designed for scalable and composable execution across shared state shards. It emphasizes linearizability, causal consistency, and determinism by structuring cross-domain interactions through explicit protocols and asynchronous messaging. Each domain (shard) handles its own commands and state transparently; inter-domain operations rely on well-defined messaging layers and proofs to preserve consistency without central coordination. The protocol supports dynamic reconfiguration: shards can split, merge, or reassign workloads while preserving correctness. By decoupling domain logic from global consensus, Linera can support modular upgrades, domain-specific smart contracts, and high throughput across partitions.

    Notify

    Notify

    A dead simple Go library for sending notifications to message services

    A dead simple Go library for sending notifications to various messaging services. Notify was born out of my own need to have my API servers running in production be able to notify me when critical errors occur. Of course, Notify can be used for any other purpose as well. The library is kept as simple as possible for quick integration and ease of use. Since Notify is highly dependent on the consistency of the supported external services and the corresponding latest client libraries, we cannot guarantee its reliability nor its consistency, and therefore you should probably not use or rely on Notify in critical scenarios.
