# Ontology > The Trust Layer for Web3 Ontology provides blockchain infrastructure and decentralized identity solutions for enterprises and developers building privacy-focused applications. Ontology is a high-performance blockchain platform focused on decentralized identity and data management. The network provides enterprises and developers with tools for building privacy-preserving applications through W3C-compliant identity standards, verifiable credentials, and zero-knowledge proofs. Ontology supports multi-chain architecture enabling cross-chain asset transfers and identity portability across blockchain ecosystems. - Type: Network - Sector: Privacy & Confidentiality - Status: Active - Founded: 2017-10-01 - Profile: https://thegrid.id/profiles/ontology ## Products - [Ontology Explorer](https://thegrid.id/profiles/ontology): A block explorer for the Ontology ecosystem. (Block Explorer, Live) - [Ontology Bridge](https://thegrid.id/profiles/ontology): A cross-chain asset transfer protocol enabling bidirectional token bridging between Ontology native assets, OEP-4 tokens, and ORC-20 tokens on Ontology EVM with wrapped asset functionality. (Bridge, Live) - [ONT ID](https://thegrid.id/profiles/ontology): A decentralized identity framework utilizing W3C DID specifications for cryptographic identity establishment, verifiable credential management, and privacy-preserving authentication across blockchain networks. (Decentralised Identity, Live) - [ONT Trust Anchor Gateway (TAG)](https://thegrid.id/profiles/ontology): A verifiable credential service providing batch identity verification and KYC authentication through integration with global trust anchors including CFCA, IdentityMind, Shufti Pro, and social media platforms. (Decentralised Identity, Live) - [OScore](https://thegrid.id/profiles/ontology): A self-sovereign credit evaluation system generating quantifiable credit scores through real-time analysis of on-chain asset balances, transaction histories, and blockchain activity patterns with cryptographic privacy protection. (Risk Assessment, Live) - [Ontology Mainnet](https://thegrid.id/profiles/ontology): A dual-token blockchain providing high-performance smart contract execution and consensus mechanisms optimized for enterprise applications requiring privacy and scalability. (L1, Live, Main Product) - [ONTO Wallet](https://thegrid.id/profiles/ontology): A non-custodial multi-chain wallet supporting digital identity management, asset storage, and decentralized application access across Ontology and EVM-compatible networks. (Wallet, Live) - [Mercury](https://thegrid.id/profiles/ontology): A decentralized peer-to-peer communication protocol enabling secure message exchange, verifiable credential transmission, and presentation sharing between DID-authenticated entities through cryptographic encryption and agent-based routing architecture. (Messaging Protocol, Live) ## Assets - [Ontology (ONT)](https://thegrid.id/profiles/ontology): ONT is the native token of the Ontology blockchain. It is used for staking to participate in network consensus, governance voting, and earning ONG rewards. Ontology features a dual-token model where ONT serves as the governance token while ONG functions as the utility token for transaction fees and smart contracts. (Native) - [Ontology Gas (ONG)](https://thegrid.id/profiles/ontology): ONG is the utility token of the Ontology network. It is used to pay for transaction fees, smart contract execution, and services like creating an ONT ID or deploying a dApp. Ontology operates a dual-token model where ONG is decoupled from ONT (the governance token) to alleviate the influence of price fluctuations on gas fees, ensuring more stable transaction costs.
