Senior Back-End Developer
About Openmesh and Xnode
In today's digital landscape, a small number of corporations hold the majority of the world's data and IT infrastructure. This concentration of power raises concerns of trust, as it can lead to social inequality, scandals, polarization, and corruption. Centralized data control creates barriers to innovation, compromises privacy, and restricts the flow of information.
Openmesh is a cutting-edge open-source cloud infrastructure combined with a global open data network. Its mission is to store critical global data without the need for intermediaries. With approximately 80% coverage of the crypto and web3 ecosystem, Openmesh is the largest open web3 data lake. In the coming years, the aim is to expand data coverage to include public health and scientific research data.
Openmesh enables users to create their decentralized data cloud, facilitating secure data sharing, reducing deployment costs, and automating data cloud setup. The Openmesh Network is designed to collect, store, process, stream, and provide data connectivity to everyone, everywhere, at any time, without registration, licensing, or payments. It acts as the open data fabric of the internet, granting universal access and preventing interference from regulators, governments, corporations, and even its own creators.
Core Products
Xnode, the flagship product of Openmesh, plays a vital role in realizing this vision. It offers a groundbreaking platform for developers to build their decentralized data clouds quickly and effortlessly. With features like data connectivity, data APIs, and query & analytics engines, developers can create fully functional data clouds in mere minutes instead of weeks or months. By leveraging Xnode, users can save costs on licensing and setup fees, resulting in a 10-15 fold reduction in running and operating data clouds and saving significant deployment time.
Pythia is a powerful analytics & query engine within the Openmesh ecosystem. It transforms raw data into actionable insights, empowering users to build, visualize, and deploy data products effortlessly.
Unified APIs serve as a single access point for all crypto & web3 data, making it freely accessible worldwide. There are no licenses, registrations, or setup fees required to use Unified APIs.
Our Vision
Openmesh's vision is to democratize data and address information asymmetry on a large scale. Data and information are immensely valuable assets, and without reliable quality data, the functionality of webpages, apps, and the entire internet is compromised. Openmesh strongly believes that access to unbiased, reliable information is a fundamental right and an integral part of a free and democratic society. The design of Openmesh follows core principles that prevent any single authority from tampering with its data, controlling information distribution, or limiting access. The entire infrastructure and technology stack are powered by open-source community governance.
