    Wasmi

    Wasmi

    Efficient and versatile WebAssembly interpreter for embedded systems

    ...Unlike JIT-based runtimes, wasmi focuses on interpretation, prioritizing portability, determinism, and low resource usage over maximum raw performance. It is particularly well-suited for blockchain systems, embedded devices, and other contexts where predictable execution and minimal dependencies are critical. The runtime implements the WebAssembly specification and provides a safe execution environment with strict sandboxing, ensuring that untrusted code cannot access host resources without explicit permission. wasmi also emphasizes modularity and embeddability, allowing developers to integrate it into their applications with fine-grained control over execution behavior. ...

    Holochain

    Holochain

    The current, performant & industrial strength version of Holochain

    Holochain is a post-blockchain framework for building agent-centric, distributed applications. Instead of using global consensus, Holochain enables each agent (user) to maintain their own local state while validating actions with a shared set of rules. This allows for scalable, secure, and resilient apps where data is owned and controlled by users. Ideal for social apps, cooperatives, and data sovereignty platforms, Holochain focuses on enabling collaboration without central servers or miners. ...

    Twiggy

    Twiggy

    Twiggy is a code size profiler

    ...It works by inspecting a binary’s call graph and providing detailed breakdowns of which functions are included and how they are interconnected, allowing developers to trace dependencies and identify unnecessary code paths. This makes Twiggy particularly useful in performance-sensitive environments such as web applications, embedded systems, and blockchain smart contracts, where minimizing binary size is critical. The tool offers multiple analysis modes that answer questions like why a function is present, how much space it consumes, and what dependencies pull it into the final binary. By surfacing insights about symbol sizes and call relationships, Twiggy enables developers to optimize builds, remove dead code, and improve load times.

    Immutable Sparse Wave Trees (WaveTree)

    Realtime bigdata tool for bit strings up to 2^63 based on AVL forest

    Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. ...
