Frequently Asked Questions

HackNodes Lab is the first Spanish company specialized exclusively in cybersecurity for the Bitcoin ecosystem. Although the formal constitution of the company is recent, our team has been providing specialized Bitcoin training for developers for more than 3 years and working on security projects for decentralized infrastructures.

We are a team of cybersecurity specialists, software developers and Bitcoin protocol experts. Our team combines practical experience in secure software development, security audits, and specialized technical training. We work with a network of expert collaborators that allows us to offer comprehensive services while maintaining the specialization that characterizes us.

Bitcoin represents the most critical and valuable infrastructure in the crypto ecosystem, with over $50B in institutional custody. Its unique architecture, specific protocols like Lightning Network, and enterprise use cases require deep knowledge that cannot be obtained with generalist approaches. Our 3+ years training Bitcoin developers have shown us that extreme specialization is what really generates value.

We perform specific audits for Bitcoin infrastructures that require deep knowledge of the ecosystem. We audit consensus and validation protocols of Bitcoin Core nodes, Lightning Network implementations, HSM and seed vault systems, and integrations with Taproot and specific BIPs. Our approach goes beyond generic audits: we understand unique attack vectors that other generalist auditors don't identify.

Our detection and response platform is designed specifically for the Bitcoin ecosystem. We monitor Bitcoin and Lightning Network nodes in real time, detect specific threats like flooding attacks and channel jamming, identify transaction anomalies, and provide 24/7 automated alerts with emergency response.

We have been training developers in Bitcoin technologies for more than 3 years, being pioneers in Spain. We offer technical workshops on secure development, Lightning Network certifications, corporate training for companies integrating Bitcoin, and cybersecurity workshops specific to the ecosystem.

While others teach generic blockchain, we focus 100% on Bitcoin and its specific ecosystem. Our courses include practical programming in Rust for Bitcoin, real implementation of nodes and Lightning channels, real cases of attacks and defenses, and access to proprietary tools developed by our team.

Yes, we develop SDKs and security libraries specifically for the Bitcoin ecosystem. We work mainly in Rust developing cryptographic validation tools, libraries for secure integration with Lightning Network, Bitcoin-native authentication modules, and testing tools for Bitcoin applications.

Large consulting firms offer generic services superficially adapted to Bitcoin. We are native specialists of the ecosystem. We have 3+ years of real experience working exclusively on Bitcoin, response speed without learning curve, we develop innovative proprietary tools, and we are an active part of the Spanish and international Bitcoin community.

We work with all types of organizations that handle critical Bitcoin infrastructure: exchanges and trading platforms, startups building on Lightning Network, financial companies integrating Bitcoin, investment funds with Bitcoin exposure, and individual developers with ambitious projects. Our approach adapts to the size and specific needs of each client.
