Blocksize on Pyth Network - A Tier 1 Data Publisher
A primary data source on the Pyth Network
Blocksize publishes its own real-time crypto market data directly into Pyth, where it's continuously checked by the network before it's trusted on-chain. The same feed we deliver to you.
The Pyth Network is a decentralized, first-party oracle that brings real-time market data on-chain. Instead of relying on middlemen to relay prices, Pyth sources data directly from the institutions that create it: exchanges, market makers, and trading firms publish their own prices straight to the network. Those sources are aggregated into a single price per asset and made available to applications across more than 100 blockchains, powering lending, derivatives, and trading.
A price feed is only as trustworthy as its sources. By taking data directly from the firms at the center of global markets, Pyth removes the intermediaries where errors and manipulation usually creep in. Each publisher contributes its own data transparently and is individually accountable for quality, so the network is only as strong as the publishers behind it.
Blocksize is a first-party data publisher on the Pyth Network. We publish our own aggregated, real-time crypto market data directly to Pyth, the same feed we deliver to customers off-chain. And we publish it accurately: Blocksize is among the lowest-deviation publishers on the network, meaning our prices track the true market more tightly than almost any other source. Accuracy you can verified.

Behind the Node
Pyth Network FAQs
From validator performance to compliance and infrastructure standards, here’s how we safeguard institutional access to the Pyth network.
If any part of your portfolio touches DeFi, on-chain derivatives or lending protocols, the prices behind those positions are set by oracle consensus. Liquidations, settlements and margin calls on-chain follow the oracle price, whatever one exchange shows. Blocksize delivers those oracle-grade prices off-chain into your systems, so your risk models match what smart contracts act on. Download our Whitepaper to learn more.

Our feeds are validated across eight leading oracle networks, which together secure around 75% of all value secured by oracles, and delivered off-chain to institutional systems. Compliance, risk and trading teams receive the same oracle-grade prices that govern DeFi smart contracts.

As a first-party 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 in every single block.
A single exchange only shows its own order book, which can drift from the real market: on even the most liquid pair, only about 25% of a top exchange's quotes sit within the true multi-venue fair value, and during stress a venue can diverge by 10 basis points or more. Listing sites like CoinGecko show a reference average, not a real-time, validated feed you can build on. We aggregate across 70+ venues in real time, filter outliers, and down-weight drifting sources, so you get the consensus price the whole market agrees on, not one venue's version of it.
