Cubane™ is building a SaaS-driven Layer-1 blockchain designed to combine enterprise-grade scalability with decentralized security.
Our core protocol is powered by the Cubic Consensus Mechanism (CCCM) and a Fully Homomorphic Encryption (FHE)-based blockchain RDBMS, enabling new standards of privacy, performance, and reliability for Web3 infrastructure.

We are assembling the Testnet Development Team — a small, hands-on group of developers contributing directly to the design and implementation of Cubane’s core systems.

Key Responsibilities

Develop and maintain protocol-level components for Cubane’s Layer-1 blockchain.
Implement and optimize decentralized P2P networking and consensus logic (CCCM).
Collaborate on system design, scalability testing, and Testnet deployment.
Contribute to code reviews, technical documentation, and open-source best practices.
Work closely with the architecture team to align FHE-RDBMS integration with consensus modules.

Required Skills & Experience

1+ year of experience in blockchain or distributed systems development.
Strong proficiency in Golang (Go) for backend and protocol development.
Understanding of consensus algorithms, networking principles, and Byzantine fault tolerance.
Familiarity with cryptography, Web3 infrastructure, or data integrity models.
Self-driven, capable of working in early-stage and high-ownership environments.

Preferred Qualifications

Prior experience with Layer-1 or Layer-2 blockchain projects.
Exposure to FHE, zk-based systems, or secure computation frameworks.
Contributions to open-source blockchain repositories or developer communities.

Why Join Cubane™

Opportunity to contribute to the core protocol layer of a new Layer-1 blockchain.
