Ruff Chain officially released the first lightweight, embedded Ruff VM which supports develop DApp by JavaScript

On November 1st, Ruff Chain, a public-chain project focused on the Internet of Things (IoT), officially released the industry’s first lightweight, embeddable virtual machine, Ruff VM that support the development of DApp in the JavaScript programming language.

Ruff VM aim to provide a uniform Blockchain DApp runtime, that helps DApp developers develop DApp by a user-friendly programming language JavaScript. Meanwhile, Ruff VM provide modules build-in, plug-in mechanism for Blockchain developer to customize the DApp runtime according to their needs. For developers, the biggest value is that they can easily port their own DApp to different Blockchain platforms.

Evolution history of traditional virtual machines and Blockchain virtual machines

With the rapid development of computers in the field of application software, a technology is urgently needed to bridge the differences between different operating systems and reduce the cost of application porting. Java Virtual Machine (Java VM) is a pioneer in the 1980s and 1990s, which can unify Windows, Unix and other underlying operating systems; The advantage is that developers no longer write code specifically for various operating systems: once Java is used to develop programs, it can be deployed across operating systems.
The blockchain field faces similar dilemmas. The most significant problem is that different software and hardware environments are not consistent in the expression of calculation results, but the consensus mechanism of blockchain requires that all calculation results must be completely consistent. Therefore, in the current blockchain industry, many blockchain platforms have launched different blockchain virtual machines, such as EVM (including smart contract operating environment and Solidity, the official language), and WASM of EOS, etc. The main purpose is to achieve the consistency of smart contract code.
In general, virtual machine technology will make a secondary abstraction of the underlying design through a proprietary programming language, allowing developers to directly develop code in the virtual machine. This technology, which strictly isolates the underlying infrastructure and the application development environment, provides both the convenience of application development and the robustness of maintaining the stability of the hardware or infrastructure. Therefore, whether in the filed of traditional application development or in the blockchain platform, virtual machines have already become an important infrastructure in the computer field.

The optimization of Ruff VM 
The Ruff VM is designed to reduce blockchain development thresholds, enhance the development experience, and provide developers with the most user-friendly blockchain core technology products. Different from the virtual machines of other blockchain platforms, Ruff VM achieves the following three performance advantages:
1. Ruff VM provides a unified DApp programming language JavaScript, which is friendly enough for developers. Compared to Ethereum’s Solidity, EOS’s WASM, JavaScript can be used immediately by ordinary developers, greatly reducing the thresholds for the development of smart contracts;
2. Ruff VM will also provide an NPM-like package registry, allowing developers of smart contracts to avoid re-creating wheels and speeding the development of their own smart contracts on different blockchain platforms. From a developer’s point of view, it is very time-saving and effort-saving.
3. Ruff VM will implement cross-platform development and deployment of DApp, including the control of memory CPU in the future, so as to control the resource consumption of DApp; at the same time, it will support the mainstream blockchain platforms such as Ethereum and EOS, which can form a friendly ecological blockchain environment to developers.
Through the powerful virtual machine technology, Ruff VM is expected to bring more possibilities for the development of blockchain. In the future roadmap, Ruff VM plans to optimize and integrate more underlying technologies and keep exploiting cross-platform features, making it easier for developers to develop and deploy smart contracts.
Currently, the Ruff VM white paper has been officially released, and all the code has been open sourced on GitHub: https://github.com/ruffchain/RuffVM
