The Evolution: From IOST to IOST 3.0
The journey of IOST reflects a clear trajectory of innovation and adaptation to market demands.
IOST 1.0: Foundation (2018)
Launched with the groundbreaking Proof-of-Believability (PoB) consensus mechanism, IOST 1.0 established a secure, efficient foundation for decentralized applications. Unlike energy-intensive Proof-of-Work models, PoB leveraged node reputation and stake to validate transactions, achieving high throughput with minimal latency. This phase focused on building core infrastructure, governance frameworks, and early community engagement.
IOST 2.0: Ecosystem Growth (2022)
With the base technology proven, IOST 2.0 prioritized ecosystem expansion. Developer tools were enhanced, smart contract capabilities improved, and strategic partnerships formed to attract builders and enterprises. The platform began supporting more complex DeFi and NFT applications, laying the groundwork for broader adoption.
IOST 3.0: Next-Generation Blockchain (2025)
IOST 3.0 is not just an upgrade—it’s a reimagining. By integrating Layer 2 scaling, cross-chain interoperability, native payment systems, and decentralized identity, IOST 3.0 addresses real-world business needs. It supports compliant asset tokenization, instant payments, and secure identity verification—all within a single, cohesive framework.

Core Architecture of IOST 3.0
IOST 3.0 employs a multi-layered architecture designed for performance, security, and flexibility:
- Layer 1 (Core Chain): Handles consensus, governance, and base-level security using an optimized version of PoB.
- Layer 2 (Scaling & Services): Hosts high-throughput applications, RWA tokenization engines, DID modules, and payment rails—drastically reducing costs and latency.
- Cross-Chain Bridge Protocol: Enables seamless asset and data transfer across major blockchains like Ethereum, BNB Chain, and others.
- Modular Smart Contracts: Support for WASM-based contracts allows faster execution and easier integration with existing developer tooling.
This layered design ensures that IOST 3.0 can scale horizontally while maintaining decentralization and security—key requirements for enterprise-grade applications.
Key Features That Set IOST 3.0 Apart
Ultra-High Transaction Throughput
IOST 3.0 achieves up to 100,000 transactions per second (TPS) through its optimized Layer 2 architecture. This performance rivals centralized systems while maintaining full decentralization—making it ideal for payment networks, gaming, and large-scale dApps.
Real-World Asset (RWA) Tokenization Framework
One of IOST 3.0’s standout capabilities is its comprehensive RWA framework. Users can tokenize:
- Real estate
- Bonds and fixed-income instruments
- Private equity
- Commodities
These assets are issued with built-in compliance controls, enabling regulatory adherence without sacrificing decentralization. The integration of DUSD, a yield-bearing stablecoin, further enhances liquidity and return potential.
Native Payment Infrastructure: PayPin & PayFi
Unlike most blockchains that rely on third-party solutions, IOST 3.0 features native payment systems:
- PayPin Ring: Enables instant, low-cost peer-to-peer transactions with biometric authentication.
- PayFi Nexus: A decentralized financial rail connecting merchants, banks, and crypto wallets for seamless cross-border payments.
- Guardian Security System: Real-time fraud detection and transaction monitoring to protect users.
These tools make IOST 3.0 a powerful contender in the global payments space.
Decentralized Identity (DID) Integration
IOST 3.0 offers native Layer 2 DID support, allowing users to:
- Verify identity via biometrics
- Complete KYC/KYB processes securely
- Authenticate across platforms without repeated verification
- Maintain control over personal data
This system enhances trust in digital interactions while complying with global privacy standards like GDPR and CCPA.
Cross-Chain Capabilities
Through its native cross-chain protocol, IOST 3.0 facilitates secure asset transfers and data interoperability with other blockchains. Developers can build dApps that pull liquidity or data from multiple chains—unlocking new possibilities for DeFi, gaming, and enterprise solutions.
How IOST 3.0 Compares to Other Blockchains
| Feature | IOST 3.0 | Ethereum | Solana | Other L1s |
|---|---|---|---|---|
| Transaction Speed | Up to 100,000 TPS | ~15–30 TPS | ~65,000 TPS | Varies |
| RWA Framework | Comprehensive | Limited | Limited | Varies |
| Payment Infrastructure | Native (PayPin + PayFi) | Third-party only | Third-party only | Varies |
| DID Solutions | Native L2 Integration | Third-party only | Limited | Varies |
| Cross-Chain Capability | Native Protocol | Third-party Bridges | Limited Bridges | Varies |
This comparison highlights IOST 3.0’s unique positioning: it doesn’t just improve speed—it adds purpose-built infrastructure for real-world utility.
