Why Blocksize?
Oracle-Grade
We operate as a tier-one data publisher across Chainlink, Pyth, Redstone and more. Every price update is independently validated by node operators and verified through on-chain consensus, creating continuous quality enforcement at every block.
Multi-Venue Fair Value
Even top-tier exchanges only fall within a tight fair-value corridor 25% of the time. Single-source feeds are incomplete. Thats why we aggregate prices from 70+ exchanges across 9,000+ pairs in real-time. Capturing the full picture of global liquidity.
Proven On-Chain
The same feeds securing $38.85B across 7 leading oracle networks are delivered directly into institutional systems via API. No other provider bridges on-chain consensus verification with off-chain institutional delivery at this scale.
Accuracy First
Our sub-250ms multi-venue VWAP updates multiple times per second. In crypto markets, exceeding settlement speed yields no practical advantage, while improving accuracy yields immense benefit. Every update arrives validated, not merely fast.
Off-Chain
Whitepaper
Real‑Time Crypto Aggregation Matters More Than Ever
Single-exchange data in crypto isn’t just incomplete – it’s statistically wrong. A global, 24/7, fragmented market, makes legacy “one feed” setups unfit for trading, risk, and valuation - we reflect on the the new normal: real-time, market-wide aggregation.

Blocksize Business Data FAQ
Common questions before our collaboration
If any part of your portfolio touches DeFi — on-chain derivatives, lending protocols, structured products with crypto underlyings — the prices that govern those positions are set by oracle consensus, not by any single exchange. A trader might see one price on Binance, but liquidations, settlements, and margin calls on-chain are triggered by the oracle price. Blocksize delivers those exact oracle-grade prices off-chain into your systems, so your risk models reflect the same reality that smart contracts act on.
We are the only data provider whose feeds are simultaneously battle-tested on-chain — securing $38.85B across 7 leading oracle networks — and delivered off-chain to institutional systems. This means your compliance, risk, and trading teams receive the exact same oracle-grade prices that govern DeFi smart contracts, validated by decentralized consensus.
We aggregate directly from 70+ exchanges with millisecond-level updates and a VWAP methodology built to oracle consensus standards. Retail aggregators typically update on multi-second or minute intervals, lack outlier filtering, and aren't validated by on-chain consensus.
As a tier-one oracle data publisher, every price update we produce is independently verified by multiple node operators across decentralized oracle networks like Chainlink, Pyth, and Redstone. Submissions that deviate from consensus are rejected, and operators providing inaccurate data face financial penalties. This creates continuous, real-time quality enforcement — not quarterly audits, but every single block.
Our VWAP methodology and full audit trails support MiFID II best execution reporting, fund NAV calculation, IFRS/GAAP fair-value hierarchy classification, and reporting across major jurisdictions.
Yes — including 30-minute VWAP snapshots for compliance reporting, audit trails, and backtesting. Historical data is available across all covered pairs.
