Irys

What Irys is

Irys is a Layer-1 programmable datachain for storing large volumes of data onchain, with flexible retention periods and verification built into the network. Its design combines storage, data availability and an EVM-compatible execution environment. The whitepaper describes smart contracts accessing and computing on stored data through IrysVM, plus separate ledgers for different retention periods, from short-term to permanent storage. Its consensus combines proof of work and staking, with penalties for malicious behavior; miners sample stored data and may be challenged and slashed if data is missing. The mainnet launched on November 25, 2025. The network is permissionless: anyone can upload through uploader.irys.xyz and retrieve content through gateway.irys.xyz. Irys says it does not prescreen uploads, accepts reports of content that violates its acceptable use policy, and actions confirmed abuse reports within 24 hours. Its open-source SDK is under the MIT license. Developers can access documentation and a faucet, while the ecosystem directory spans areas including AI, compute, trust and security, developer infrastructure, DeFi and social platforms. The maker is BN Labs Ltd, trading as Irys, registered in England and Wales with a London address.
