EOS is a blockchain platform for the development of decentralized applications (dapps), similar to Ethereum in function. It provides a complete operating system for decentralized applications focused on the web with services like user authentication, cloud storage, and server hosting.
EOSIO is a free, open-source blockchain software protocol that provides developers and entrepreneurs with a platform on which to build, deploy and run high-performing decentralized applications (DAPPs)
EOSIO based blockchains execute user-generated applications and code using WebAssembly (WASM). WASM is an emerging web standard with widespread support of Google, Microsoft, Apple, and industry leading companies.
At the moment the most mature toolchain for building applications that compile to WASM is clang/llvm with their C/C++ compiler. For best compatibility, it is recommended that you use the EOSIO toolchain.
Other toolchains in development by 3rd parties include: Rust, Python, and Solidity. While these other languages may appear simpler, their performance will likely impact the scale of application you can build. We expect that C++ will be the best language for developing high-performance and secure smart contracts and plan to use C++ for the foreseeable future.
Exonum is an extensible framework for blockchain projects. Exonum enables you to build decentralized, secure and reliable blockchain applications.Exonum enables you to build decentralized, secure and reliable blockchain applications. It is designed to allow people, companies and governments to design custom private or permissioned blockchains that benefit from the unmatched security of public blockchains.
Exonum brings all the advantages of a true blockchain — auditability, transparency, and unparalleled security — and combines them with privacy, efficiency and controllability.
Exonum is a blockchain framework that allows building secure permissioned blockchain applications. Like all software, Exonum comes with its own set of features and capabilities. This page outlines the cases in which Exonum could be useful and points out the main differences between Exonum and other distributed ledger solutions.
Exonum is a framework; it's not a ready-made blockchain (like, say, Bitcoin). Instead, Exonum can be used to create blockchains, just like MVC frameworks (e.g., Django or Express) can be used to create web applications.
Exonum is geared towards permissioned blockchains. This means that only a limited list of nodes can commit transactions to the blockchain. Such approach is reasonable if there is a certain maintainer (or several maintainers) that should retain some control over the network (e.g., define and update transaction processing rules). Compared to permissionless blockchains (such as Bitcoin), Exonum applications are more local, but at the same time provide greater flexibility and a more controllable environment.
Macchina is an open source software toolkit for quickly building embedded applications for the Internet of Things that run on Linux-based IoT gateways and devices like the Raspberry Pi, Beaglebone, RED Brick or Galileo/Edison.
Runs on Embedded Linux devices with as little as 32 MB of RAM, as well as desktop Linux and OS X. Develop and test on desktop machine, then easily deploy to embedded device.
It runs on Linux-based devices, including IoT gateways, industrial computing devices, and prototyping platforms like the Raspberry Pi, Beaglebone and MangOH.
