The top tokenized stocks, one price each
35 stocks plus gold and silver, built from several issuers and venues, 36 of 38 stock feeds within 0.20% at P99 in market hours, in the tested sessions. The aggregation across issuers is done, with a published methodology.
A price at every hour
Pricing continues outside market hours and on weekends from eligible exchange quotes. RWA perp feeds are coming soon.
Rights to publish on-chain
Full redistribution rights available, as part of Enterprise or agreed individually, at a fraction of the cost of licensed exchange data.
Crypto, as before
Crypto feeds for 9,000+ pairs, published into eight networks today, plus state prices for thin markets.
One Price, Whole Market.
Crypto liquidity is scattered. There is no consolidated tape and no single official price. The same asset trades at different levels on every venue, and the gaps widen exactly when accuracy matters most. Even the deepest exchanges sit within market-wide fair value only 25% of the time. Blocksize aggregates into one price the whole market agrees on.

Blocksize Methodology
Accuracy You Can See.
Performance You Can Trust.
Real-time aggregated price feeds benchmarked against top exchanges, built for mission-critical use cases.
Price Provider Selection
Live Price Feed Comparison
Outlier Detection
Individual trades are filtered using confidence interval models. If a trade price significantly deviates from the statistical norm, it is excluded.
Dynamic Source
We continuously monitor exchange behavior for consistency and accuracy. Markets that show sustained drift, staleness, or unreliable volume are dynamically excluded.
Contingency Logic
We have clearly defined rules in place to address rare situations where data is delayed, missing, or unavailable — such as during low liquidity events or extraordinary market conditions.

Governance by Design
All methodology rules are overseen by the Blocksize Data Committee. Inclusion of new data sources or methodological changes follow formal review — combining automation with expert accountability.
