[\\[1\\]](#cite-id-0zl13j682hzc) $$widget0 [YOUTUBE@VID](W1H4wd--wIQ)$$  \n  \n# Overview  \n  \nDIA is a cross-chain, open-source platform that offers data and [oracle](https://iq.wiki/wiki/oracle) services for [Web3](https://iq.wiki/wiki/web3), sourcing and distributing verified data feeds for traditional and digital financial systems. It operates as a trustless [oracle](https://iq.wiki/wiki/oracle) network, delivering data for various assets across [blockchains](https://iq.wiki/wiki/blockchain). It is supported by a permissionless system where [nodes](https://iq.wiki/wiki/node) and [stakers](https://iq.wiki/wiki/staking) participate in data sourcing, secured through [crypto](https://iq.wiki/wiki/cryptocurrency)-economic and cryptographic methods. DIA's [Ethereum](https://iq.wiki/wiki/ethereum) [L2](https://iq.wiki/wiki/layer-2) [rollup](https://iq.wiki/wiki/rollup), \"Lasernet,\" handles essential [oracle](https://iq.wiki/wiki/oracle) functions, ensuring trustless computation and verifiability. [\\[2\\]](#cite-id-mpexn0czfye)  \n  \n# Products  \n  \n## Asset Price Feed  \n  \nDIA token price feeds provide real-time information for over 3,000 [cryptocurrencies](https://iq.wiki/wiki/cryptocurrency) sourced from over 80 high-volume [decentralized](https://iq.wiki/wiki/decentralized-exchange) and [centralized exchanges](https://iq.wiki/wiki/cex-centralized-exchange). These feeds support various [DeFi](https://iq.wiki/wiki/defi) use cases, including lending, synthetic asset issuance, and [derivatives](https://iq.wiki/wiki/derivative). DIA constructs feeds using trade data from multiple transparent sources, ensuring extensive asset coverage and customizability. The feeds are processed with customizable methodologies such as outlier filtering and advanced pricing techniques. They can be delivered off-chain and on-chain across 35+ integrated [blockchains](https://iq.wiki/wiki/blockchain) through APIs or [oracles](https://iq.wiki/wiki/oracle). [\\[3\\]](#cite-id-7r3knt9tlux)[\\[4\\]](#cite-id-2sdo765d8wy)  \n  \n## NFT Floor Price  \n  \nDIA xFloor provides real-time price feeds for over 18,000 [NFT](https://iq.wiki/wiki/non-fungible-token-nft) collections, enabling integration into [DeFi](https://iq.wiki/wiki/defi) using direct on-chain trade data from multiple [NFT](https://iq.wiki/wiki/non-fungible-token-nft) marketplaces. It offers customizable price feeds that are resilient to manipulations through advanced methodologies and supports deployment on-chain or via API to meet specific user needs. [\\[7\\]](#cite-id-ik3fpxidxcq)  \n  \n## Randomness  \n  \nDIA xRandom provides [smart contracts](https://iq.wiki/wiki/smart-contract) with verifiable and unbiased random numbers through drand’s distributed randomness beacon, updated every 30 seconds. It enables a wide range of on-chain applications, such as gaming, lotteries, prediction markets, and [NFT](https://iq.wiki/wiki/non-fungible-token-nft) launches, by offering a secure and decentralized randomness [oracle](https://iq.wiki/wiki/oracle) across 20+ [L1](https://iq.wiki/wiki/layer-1) and [L2](https://iq.wiki/wiki/layer-2) [blockchains](https://iq.wiki/wiki/blockchain). DIA’s decentralized [node](https://iq.wiki/wiki/node) network, xNode, ensures the efficient and secure distribution of randomness on-chain while preventing manipulation of the generated results.

This approach allows for more accurate and transparent pricing, helping [DeFi](https://iq.wiki/wiki/defi) protocols manage risk and support use cases like lending, borrowing, and money markets. The xLSD feeds assess the collateralization of base tokens and [derivatives](https://iq.wiki/wiki/derivative) and offer customizable parameters for various protocols across 30+ [blockchains](https://iq.wiki/wiki/blockchain).

These price feeds support the development of on-chain applications such as financial [derivatives](https://iq.wiki/wiki/derivative), [stablecoins](https://iq.wiki/wiki/stablecoin), prediction markets, and tokenized [real-world assets](https://iq.wiki/wiki/real-world-assets-rwas). [\\[10\\]](#cite-id-uxmmj0lz3r)  \n  \n# Oracles  \n  \n## Nexus  \n  \nNexus is a flexible [oracle](https://iq.wiki/wiki/oracle) solution designed to meet the cross-chain needs of [decentralized applications](https://iq.wiki/wiki/decentralized-application). It gathers first-party market data directly from exchanges, avoiding third-party data providers, and processes this raw data into reliable price feeds using transparent computational methods. These feeds are then delivered via API and pushed on-chain through [oracle](https://iq.wiki/wiki/oracle) [smart contracts](https://iq.wiki/wiki/smart-contract), supporting major [Layer-1](https://iq.wiki/wiki/layer-1) and [Layer-2](https://iq.wiki/wiki/layer-2) [blockchains](https://iq.wiki/wiki/blockchain). Nexus operates through three stages: sourcing granular market data from various exchanges, processing it with transparent methodologies, and delivering the feeds on-chain through a decentralized [node](https://iq.wiki/wiki/node) network. [\\[11\\]](#cite-id-oaykfuu7b9)  \n  \n## DIA Lumina  \n  \nDIA Lumina consists of modular components built around Lasernet, an [Ethereum](https://iq.wiki/wiki/ethereum) [Layer-2](https://iq.wiki/wiki/layer-2) [rollup](https://iq.wiki/wiki/rollup) that handles key operations like data storage, computation, and verification. It uses [staking](https://iq.wiki/wiki/staking) incentives for decentralized data sourcing, [zero-knowledge proofs](https://iq.wiki/wiki/zero-knowledge-proofs-zkps) for off-chain data validation, and cross-chain messaging for [oracle](https://iq.wiki/wiki/oracle) data delivery. Lumina integrates several features, such as Feeders that fetch trade data from exchanges, Pods that store price data on-chain, and Aggregators that produce median values using customizable rules. Lasernet, the core of DIA Lumina, functions as an open, scalable data chain powered by the DIA token designed for interoperability and decentralized data sharing.

These include DIA Improvement Proposals (DIPs) for product-related changes, General DIA Proposals (GDPs) for operational or community matters, Community Approval Requests (CARs) to streamline product category approval, and Custom Delivery Requests (CDRs), which allow [dApps](https://iq.wiki/wiki/decentralized-application) to request tailored data feeds. [\\[14\\]](#cite-id-6z9onqoies9)  \n  \n# DIA Token  \n  \nThe DIA Token allows the community to govern the platform, with members proposing ideas that, if supported, move to a vote via [Snapshot](https://iq.wiki/wiki/snapshot). Updated [tokenomics](https://iq.wiki/wiki/tokenomics) include [staking](https://iq.wiki/wiki/staking) incentives, where [node](https://iq.wiki/wiki/node) operators and delegators earn rewards by securing the network, and mechanisms like market-buying DIA to support long-term [tokenomics](https://iq.wiki/wiki/tokenomics). Additionally, DIA functions as the [gas](https://iq.wiki/wiki/gas) token for the Lasernet [rollup](https://iq.wiki/wiki/rollup), collecting [transaction fees](https://iq.wiki/wiki/transaction-fee) to enhance its utility. DIA has a total supply of 200M tokens.
