Junior Solidity Developer (Smart Contract Development)
About Openmesh and Xnode
Today, a few large corporations control the majority of the world's data and IT infrastructure. This centralized control of data is detrimental to businesses and society as a whole. It leads to inequality, scandals, corruption, and even wars. Openmesh is a cutting-edge open-source cloud infrastructure and open data network that aims to store global data without the need for intermediaries. It is a significant player in the crypto and web3 ecosystem, covering approximately 80% of it. In the coming years, Openmesh plans to expand its data coverage to include public health and scientific research data.
Openmesh allows anyone to create their decentralized data cloud, enabling secure data sharing, cost reduction in deployment, and automation of setup. It is like the open data fabric of the internet, providing universal access and preventing interference from regulators, governments, corporations, or its creators.
Core Products
Our flagship product, Xnode, is a revolutionary platform that enables developers to build their decentralized data clouds quickly. It offers data connectivity, APIs, and analytics engines with significant cost reduction and time savings compared to traditional methods.
Pythia is a powerful analytics and query engine that transforms raw data into actionable insights for designing and deploying data products.
Unified APIs provide a single access point for all crypto and web3 data, available without any costs or setup fees.
Our vision
We aim to democratize data and address information asymmetry on a large scale. Quality and reliable data are essential for the proper functioning of the internet and society. Openmesh believes that access to unaltered information is a fundamental right and is committed to open-source principles.
