Why Blocksize

Verified where it matters most

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.

Why Blocksize

Outstanding Accuracy

Every price is held inside a tight fair-value accuracy corridor — bad prints, stale books, and drifting venues are detected and down-weighted instantly. Operated from compliant infrastructure in Germany, with 24/7 monitoring, automated failover, and a hands-on engineering team behind it. Reliability and accuracy you can build on.

Why Blocksize

Network Contribution

We aggregate the market data, run the RPC infrastructure that carries it on-chain, operate the publishing, and stay active in the networks — staking our own funds, voting in governance, and open-source contribution. Our long-term commitment strengthens the ecosystems we believe in.

Why Blocksize

Made in Germany

Blocksize is incorporated in Germany — operating under strict legal frameworks with full transparency and accountability. We operate highly reliable infrastructure, giving our partners confidence in every transaction.
