Irys.

This dual system, combined with a hybrid Proof of Work (PoW) and Proof of Stake (PoS) model, optimizes the verification process, reduces risks of centralization, and incentivizes miners to store data correctly​

Irys Virtual Machine (IrysVM)

The IrysVM is a core element that supports programmable data. It allows smart contracts to access and manipulate on-chain data directly, unlocking new possibilities for applications that require real-time data interaction:

• EVM Compatibility: Developers can deploy Ethereum-compatible contracts, leveraging the extensive Ethereum ecosystem.
• Enhanced Storage Integration: The IrysVM supports direct access to the data layer, simplifying the development of data-driven applications.
• Flexible Execution Models: Supports various execution methods like deferred validation, off-chain computation, and WASM-compiled code, which make it suitable for diverse use cases​

Matrix Packing and Efficient Sampling

Matrix Packing and Efficient Sampling are Irys’s innovative approaches for data verification:

• Matrix Packing: Ensures cryptographic integrity by embedding fingerprints in stored data, allowing fast, economical verification even on lower-power devices.
• Efficient Sampling: Optimizes mining by enabling miners to access data in packed partitions without overlapping reads, reducing costs and barriers for miners​

Unique Capabilities

Programmable Data

Irys’s integration of storage and execution enables “Programmable Data,” which allows applications to manipulate on-chain data in real-time:

• Smart Contract Observation: Enables contracts to monitor on-chain activity and respond programmatically.
• On-chain Data Validation: Smart contracts can access, verify, and validate data during execution, making it possible to build real-time, responsive applications, such as social media platforms, AI training models, and dynamic financial contracts.

Verifiability

Irys prioritizes verifiability, ensuring data integrity without intensive computational costs:

• Optimized Data Preparation: Matrix Packing minimizes verification load, making data accessible and verifiable on standard devices.
• Inclusive Verification: Users can participate in data verification on standard hardware, which democratizes access and reduces reliance on specialized infrastructure​
