Who Is Blocksize

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.

Real-Time Crypto Data

Best-in-class market data, aggregated in real time across all major exchanges. Built for the highest standards of decentralized oracle networks, developers, and financial institutions.

Consensus Proven

We publish into the leading oracle networks, where pricing accuracy matters most. Every price is checked by consensus before billions in value rely on it.

One Price, Whole Market.

Crypto liquidity is scattered. We aggregate in real-time across all major exchanges and verify the result on-chain — so the price you get is the one the market agrees on.
