Band is a decentralized oracle built on its own blockchain, BandChain. Applications request data through programmable scripts, and BandChain's validators fetch that data from external sources, report it, and aggregate the results into a single verified value that can be delivered to any blockchain. Built on the Cosmos SDK, it reaches fast finality through validator consensus. *hover to read* Its model ### Why Band's model is different On most oracle networks, fetching data and securing the chain are separate jobs. Band combines them: the same validators that produce blocks are the ones that retrieve and report the requested data. That means the parties securing the network are directly accountable for the data it delivers: data integrity and chain security are enforced by the same set of operators. *hover to read* Our role ### Blocksize on Band Blocksize runs a validator on BandChain. That means we take part in the network's consensus and, as part of that role, fetch and report real-time crypto market data when applications request it. We help secure the network and contribute the data it serves, backed by the same aggregated market data we deliver to our customers off-chain.

Blocksize validator → oracle report on BandChain → relayed to the target chain. 03 Checked · Ask count, min count ## Tested by consensus, every update. A request asks a stake-weighted set of validators; the result is aggregated once the minimum count has reported. Our accuracy is not a claim we make. Band measures it each time we submit. 04 Secured ## Every minute, on the record. Node uptime 99.99% per network. The status page lists each downtime minute instead of a badge.

Liquidity is scattered; no venue alone is the market. 02 · Aggregation 9,000+ pairs, outliers filtered, drifting venues down-weighted, rules under the Data Committee. 03 · Oracle reporter Fetches and reports our price when a request asks our validator. 04 · Validator Produces and signs BandChain blocks. 05 · BandChain aggregation Results are aggregated once the minimum count has reported. Why it matters to Band ## What vertical integration gives a network. Accuracy ### No hand-offs between trade and chain The price leaves our aggregation and reaches the network through our own nodes. Nothing in between can round, delay or replace it. Tested in public ### Every update meets consensus Each submission is compared with the other sources before it counts. Our accuracy is measured by the network, update after update, not by us. Security ### Fewer parties in the path Own publisher nodes, own RPC endpoints, own keys. A shorter path has fewer places to attack and fewer parties to trust. Liveness ### One team watches every layer Exchange outages are absorbed in aggregation; node and RPC failover is ours. The status log shows every minute. Accountability ### One name on every layer If a value is wrong, it is ours at every step, and networks penalise bad data. Incentives point one way. Diversity ### An independent operator A first-party source with its own aggregation and infrastructure adds an independent voice to each network's consensus.

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.

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. ![Group 36(1)](https://blocksize.info/files/8a7100e7-524d-4675-ad73-db96894343ff/Group%2036(1).svg) ### How is your data different from CoinGecko or CoinMarketCap? 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. ![Building Illustration](https://blocksize.info/files/d26adfc4-a548-4c0c-988c-69db957628cd/building_illustration.png) ### How is your data quality validated? 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. ![Computer Illustration](https://blocksize.info/files/8a93e958-8c9b-4246-af5d-b03e6603bf85/computer_illustration.png) ![Group 36(2)](https://blocksize.info/files/c9417b59-f425-42de-a5b6-9cfcbd1a5746/Group%2036(2).svg) ![Group 36(1)](https://blocksize.info/files/8a7100e7-524d-4675-ad73-db96894343ff/Group%2036(1).svg) ![Building Illustration](https://blocksize.info/files/d26adfc4-a548-4c0c-988c-69db957628cd/building_illustration.png) ![Computer Illustration](https://blocksize.info/files/8a93e958-8c9b-4246-af5d-b03e6603bf85/computer_illustration.png) For Band teams ## Add Blocksize as a source.
