Blocksize Reviews & Provider Details

Blocksize is a crypto market data provider. Crypto has no consolidated tape and no official closing price. The same asset trades at different levels on every venue at once, and the gaps widen when accuracy matters most. Any single-exchange price is a partial view, which makes it hard to defend in a valuation, a fill review or an audit. We aggregate pricing in real time from more than 70 exchanges across 9,000+ instruments into one reference price per pair. Outliers are filtered continuously and venues that drift from the market are excluded until they return. The full methodology is published. We also operate the infrastructure that delivers this data on-chain across the 8 leading oracle networks, so every price we submit must hold against consensus before it is accepted. Asset managers, funds and family offices use Blocksize for NAV, fair-value marks and reporting. Trading firms and brokers use it as an independent execution benchmark. Oracle networks use it to price the assets that on-chain lending, settlement and liquidations depend on.
