The Future We Build Toward
Our vision is to safeguard the shift of the financial services industry into DeFi.
Technical Excellence
We operate our infrastructure in compliant environments — supported by 24/7 monitoring, automated failover, custom alerting systems to ensure institutional-grade reliability.
Network Contribution
We demonstrate long-term commitment through self-stake, governance participation, open-source development, and RPC access.
Quality Leadership
Blocksize meets the highest technical standards. In DeFi, transparency and consensus don’t tolerate shortcuts — anything less is excluded by design.
Made in Germany
Operating under legal frameworks with full transparency and accountability. We combine state of the art infrastructure with regulatory clarity, giving our clients confidence in every transaction.
The Role We Play
We see it as our mission to bridge financial services and blockchain ecosystems — by securing blockchains and enabling institutional access to DeFi.
Who We Are
Blocksize is a Germany-based DeFi infrastructure provider trusted by financial institutions. Since 2018, we’ve been strengthening DeFi at every layer — operating our own node infrastructure, delivering real-time crypto data, and enabling anyone to participate in network security through delegated staking.
Engineer for Stability
We prioritize resilient infrastructure — ensuring performance and uptime across the decentralized networks we support.
Act With Stewardship
We take responsibility for what we run — securing the ecosystem’s integrity through diligence, discipline, and transparency.
Connect the Ecosystems
We bridge ecosystems with a clear goal: make decentralized finance reliable, accessible, and usable for institutions.
Build With Trust
We foster confidence through transparency, accountability, and communication — so partners always feel secure, informed, and in control.
Made in Germany.
Built for DeFi.
From Frankfurt to the world — where financial present meets financial future.
Our Belief
We believe in a future of finance where trust should be distributed, not owned.
Decentralization isn’t just a technical shift - it’s a structural correction.
Christian Labetzsch
Co-Founder, Blocksize
Centralized systems fail in silence. Decentralized ones fail out loud - and that’s a strength.
We’re here to help build systems that fail better and recover faster.
