The Future We Build Toward
Our vision is to safeguard the shift of the financial services industry into DeFi.
Oracle-Verified
Our data is published into the leading oracle networks, where every update is checked by consensus before it's trusted on-chain. The same feed that prices billions on-chain is the one you get.
Network Contribution
We aggregate the market data, operate the publishing infrastructure that delivers it on-chain, and stay active in the networks — running RPC nodes where needed, self-staking our own funds, voting in governance, and contributing open-source tooling. Our long-term commitment strengthens the ecosystems we believe in.
End-to-End
We operate across the oracle value chain. Making DeFi more secure and accessible. To do so, we operate publishers in all leading oracle networks and aggregate the data mission-critical use cases depend on. We know the price is right, and we make that accuracy available to everyone.
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
Our mission is to make digital assets bankable — bridging the on-chain and off-chain worlds by delivering the same verified market data that secures DeFi to everyone who can't afford a wrong price.
Who We Are
Blocksize is the trusted source of crypto market data, engineered for and relied upon by the leading decentralized oracle networks. Since 2018, from Germany, we've operated across the full oracle value chain — aggregating real-time market data, operating the infrastructure that publishes it on-chain, and securing the networks that depend on it. The same verified feed that prices billions on-chain is the one we deliver to everyone off-chain.
Build With Trust
We foster confidence through transparency, accountability, and communication — so partners always feel secure, informed, and in control.
Connect the Ecosystems
We bridge ecosystems with a clear goal: make decentralized finance reliable, accessible, and usable for institutions.
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.

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
Decentralization isn’t just a feature — it’s the foundation that keeps finance honest, resilient, and free from gatekeepers, built on trustless consensus.
