About Openmesh and Xnode

In today's world, a small number of companies control a majority of the data and IT infrastructure, which creates issues of trust and inequality. Openmesh is an innovative open-source cloud infrastructure and global open data network that aims to store important data without any intermediaries. It is the largest open web3 data lake, encompassing a significant portion of the crypto and web3 ecosystem. Openmesh plans to expand its data coverage to include public health and scientific research data in the upcoming years.

Openmesh allows individuals to create their own decentralized data cloud, enabling global connectivity, secure data sharing, cost reduction, and automated setup. The Openmesh Network is designed to collect, store, process, stream, and provide data connectivity to anyone without registration, licensing, or payments. Think of Openmesh as the internet's open data fabric, granting universal access while preventing interferences from authorities, governments, corporations, or its creators.

Remote
Game Concept: “Reflex Arena”
Genre
Real-time competitive 1v1 / 2v2 skill-based action game
Platform
iOS (iPhone first, iPad optional)
Core Idea
A pure skill game where players compete in short, intense arena matches using precision timing, reflexes, and positioning — no RNG, no pay-to-win.
Each match lasts 60–90 seconds, making it ideal for mobile sessions while supporting competitive depth.
Core Gameplay Loop
Matchmaking
Skill-based MMR
Ranked & unranked queues
Arena Match
Small symmetrical arena
Players control a single character
Objective: score points by outplaying, not overpowering

Win → rank up
Lose → learn (clear replay & stats)
Cosmetics only progression
Controls (Mobile-First, High Precision)
Left thumb: Movement (virtual joystick)
Right thumb: Aim + action swipe
Tap: Ability activation
Perfect timing windows reward precision (parries, counters)
👉 Designed to feel closer to a fighting game than a casual mobile title.

Rust/blockchain

Houston, USA
Houston, USA
Part time

I am seeking a world-class Systems Engineer / Rust Architect to build a proprietary asset extraction engine on the Solana network. This is not a "Web3 App" or a "DEX UI." This is a purely backend, low-latency machine designed to capture micro-value from market volatility.​The system mimics a "digital sluice," using high-precision math to harvest fractional differences that standard rounded-math bots ignore. We are scaling from a prototype to a 30-node distributed network managing 100+ concurrent execution "hands."​Core Technical Requirements​Low-Level Rust Mastery: You must be an expert in the Tokio runtime, asynchronous programming, and memory-safe mathematical operations.​Solana Network Physics: Deep understanding of the Sealevel runtime, custom WebSocket/Lumen bridges, and avoiding gRPC bottlenecks.​Jito & MEV Optimization: Proven experience with Jito Bundles, transaction shredding, and tip-optimization to ensure first-block inclusion.​Distributed Orchestration: Ability to architect a master-node system that manages 30+ regional nodes with seamless failover and zero-loss state management.​Precision Math: All logic must operate on u64 integers (Lamports) to avoid floating-point rounding errors. We do not "round" to the dollar; we capture the 9th decimal.​Key Responsibilities​Engine Hardening: Audit and optimize the core Rust logic for 0-latency execution.​Node Orchestration: Build the "Master Switch" to deploy, monitor, and update 30 nodes across global regions simultaneously.​The "Tax" Logic: Implement a secure, automated "sweeper" protocol that collects fractional value from all child-nodes into a master treasury without interrupting execution.​Redundancy: Ensure the system is "Anti-Fragile"—if a validator or node fails, the 50-drop safety protocol must trigger an instant failover.
