What Makes IoTeX Unique?

IoTeX is unique because it was purpose-built to connect real-world devices, data, and AI into a single blockchain-powered ecosystem. Unlike general-purpose blockchains that were later adapted for machine use, IoTeX’s architecture was designed from day one to verify data from physical devices and make it usable for decentralized applications and intelligent systems.

A defining innovation of IoTeX is Realms—a new type of data primitive. Realms serve as living knowledge bases that continuously evolve as participants contribute and as AI systems consume, learn from, and adapt to them. Each Realm organizes verified, contextualized data into queryable environments tailored to domains such as mobility, energy, health, and robotics. This allows AI to access real-time insights about the physical world and act safely and intelligently.

IoTeX also combines performance and trust at the base layer. Its Roll-DPoS consensus delivers fast finality and throughput of up to 2,000 transactions per second (TPS), making it one of the fastest EVM-compatible chains. The network has a Nakamoto coefficient of 9, which is roughly four times more decentralized than Ethereum, underscoring its strong security and resilience. On top of this, ioID provides verifiable digital identities for both humans and machines, while Quicksilver AI introduces the first AI agent framework built specifically for DePINs, enabling decentralized AI agents to interact directly with trusted machine data.

By uniting Realms, verifiable identity, high-throughput infrastructure, decentralized security, and AI-native frameworks, IoTeX provides the foundation for the AI + real-world data economy.

How much data can I store on the IoTeX blockchain? Does it support on-chain data storage?

The IoTeX blockchain primarily focuses on decentralized identity, data, and device management for the Internet of Things (IoT). While it does support on-chain data storage, the capacity is limited compared to traditional databases or off-chain storage solutions. Here’s what you need to know:

1. On-Chain Data Storage on IoTeX

  • IoTeX uses a UTXO (Unspent Transaction Output) model similar to Bitcoin, which means data is stored in transactions and smart contracts.
  • Storage is limited because each transaction has a size limit (typically a few KB per transaction).
  • Smart contracts can store data, but the storage is expensive and not scalable for large datasets.

2. Off-Chain Storage Solutions

Since on-chain storage is costly and limited, IoTeX encourages using off-chain storage with on-chain verification:

  • IPFS (InterPlanetary File System) – Store large files off-chain and reference them via IPFS hashes on-chain.
  • BigchainDB – A decentralized database that can be integrated with IoTeX.
  • Decentralized Storage Networks (DSNs) like Filecoin, Arweave, or Sia can be used for large-scale data storage.

3. Use Cases for On-Chain Data

  • Device identity & authentication (IoTeX’s UCam and Pebble Tracker use on-chain identities).
  • Small metadata (e.g., device status, ownership proofs).
  • Smart contract logic (e.g., token contracts, DAO governance).

4. Cost & Scalability

  • On-chain storage is expensive (gas fees apply for each write).
  • Off-chain + on-chain verification is more cost-effective for large datasets.

Conclusion

  • For small, critical data → Use on-chain storage (transactions/smart contracts).
  • For large datasets → Use off-chain storage (IPFS, BigchainDB, etc.) with on-chain hashes for verification.

Would you like recommendations on integrating IoTeX with off-chain storage solutions?
