The IOST blockchain has emerged as a forward-thinking platform aiming to bridge real-world assets (RWA) with decentralized finance (DeFi), digital identity, and next-generation Web3 applications. With a series of strategic upgrades, ecosystem expansions, and innovative hardware integrations, IOST is redefining its role in the evolving blockchain landscape. This article explores the latest developments, core technology, tokenomics, and future roadmap of IOST—offering a comprehensive overview for investors, developers, and crypto enthusiasts.
Recent Developments and Ecosystem Expansion
Signet Ring: Biometric Identity Meets Blockchain
In June 2025, IOST unveiled Signet Ring, a groundbreaking wearable hardware module that merges biometric authentication with blockchain security. Utilizing a proprietary “Proof of Heartbeat” mechanism, the ring captures heart rate and heart rate variability (HRV) to enable decentralized, tamper-proof digital identity verification.
This innovation marks a major step toward secure, user-owned identity solutions within the IOST ecosystem. As a modular entry point into IOST’s RWA infrastructure, Signet Ring not only verifies identity but also doubles as a health tracker—monitoring stress levels and cardiovascular patterns. By linking physical well-being with digital access, IOST is pioneering a new paradigm where personal health data can be securely leveraged for authentication without compromising privacy.
🔍 Why it matters: In an era of rising digital fraud and identity theft, decentralized biometric authentication offers a trustless yet highly secure way to verify users—without relying on centralized databases.

DUSD+ Stablecoin Launch: Bridging RWA and DeFi
Also in June 2025, IOST powered the launch of DUSD+, a next-generation yield-generating stablecoin developed by Darwin Labs and Paimon Finance. Unlike traditional stablecoins pegged to fiat, DUSD+ is backed by institutional-grade private credit exposure through Blackstone’s BCRED fund.
Powered by Darwin Labs’ AI-driven RAISE Engine (Real Asset Intelligent Stablecoin Engine), DUSD+ introduces dynamic risk assessment and asset tokenization. It further integrates Paimon’s High-Yield Debt (HYD) mechanism, enabling tiered returns for holders. This fusion of regulated financial instruments with DeFi protocols positions IOST at the forefront of the RWA tokenization movement.
Strategic Funding and Global Expansion
On June 6, 2025, IOST announced a $21 million strategic funding round led by DWF Labs, Presto, and Rollman Management Groups. The capital infusion is earmarked for expanding IOST’s real-world asset infrastructure in regulated markets, accelerating product development, growing validator participation, and deepening ecosystem integration.
With a focus on Japan and broader Asian markets, IOST plans to extend its footprint into the Middle East, Europe, and North America—signaling strong institutional confidence in its long-term vision.
Network Migration and Exchange Updates
Bithumb Suspends IOST Deposits Amid BSC Migration
Due to IOST’s migration to the BNB Smart Chain (BEP20), South Korean exchange Bithumb suspended deposit and withdrawal services for IOST on June 9, 2025. Trading remained unaffected during the transition period. Once migration is complete, all IOST tokens will operate exclusively on the BNB Smart Chain.
This move aligns with IOST’s strategy to enhance scalability and interoperability by leveraging BSC’s high-throughput Layer 1 infrastructure while maintaining its own Layer 2 innovations.
Binance Completes BSC Integration
Earlier in April 2025, Binance completed the integration of IOST on the BNB Smart Chain and reopened deposit and withdrawal functionalities. This upgrade improves transaction speed and reduces fees for users, enhancing overall liquidity and accessibility.
However, in July 2024, Binance delisted the IOST/BTC trading pair as part of routine portfolio optimization—reflecting evolving market dynamics rather than project health.
Tokenomics and Distribution Strategy
Token Supply and Branding Evolution
In January 2025, IOST finalized a successful community vote to double its total token supply from 213.2 billion to 426.4 billion IOST over a 60-month period. Crucially, 97% of newly minted tokens are allocated to the community, ensuring fair distribution and long-term decentralization.
The rebranding also introduced a refreshed visual identity and updated website (iost.io), emphasizing IOST’s evolution into a BSC Layer 2 solution with enhanced scalability and cross-chain functionality.
StakeDrop and Airdrop Initiatives
To incentivize participation and reward early adopters, IOST launched several community-driven programs:
- StakeDrop Program (April 2025): Distributes 14.924 billion IOST through a time-locked staking mechanism with multipliers up to 4.5x, based on lock duration and user tier.
Airdrop Campaigns: Multiple distributions totaling over 42.6 billion IOST were planned across phases:
- 40% to existing holders
- 35% to new users
- 23% for ecosystem development
- 2% for early voters
These initiatives aim to foster sustainable growth by prioritizing long-term engagement over speculative behavior.
Core Technology: Powering Scalable Decentralization
Proof of Believability (PoB) Consensus
At the heart of IOST’s architecture lies its proprietary Proof of Believability (PoB) consensus mechanism—a hybrid model combining elements of Proof of Stake (PoS) with reputation-based validation.
Key features include:
- Servi Scoring System: Nodes earn "Servi" points through network contributions like transaction validation and data storage.
- Dynamic Node Rotation: High-frequency rotation prevents centralization; once a node produces a block, its Servi balance resets.
- Equal Reward Distribution: Ensures smaller validators have fair opportunities to participate and earn rewards.
Compared to EOS’s DPoS model—which relies on a small set of elected super nodes—IOST’s PoB offers superior decentralization while maintaining high throughput.
Scalability Through Layered Architecture
IOST addresses blockchain’s scalability trilemma (security, decentralization, scalability) via a multi-layered approach:
- Layer 1: Base chain using PoB for secure consensus.
- Layer 2 Solutions: Includes state channels, sharding, and sidechains to boost transaction capacity.
- IOST 3.0 Upgrade (March 2025): Introduced an advanced Layer 2 network optimized for RWA tokenization and frictionless asset conversion between traditional and digital finance systems.
This layered design enables thousands of transactions per second (TPS), making it ideal for enterprise-grade applications and mass-market adoption.
Use Cases and Ecosystem Partnerships
Web3 Gaming: CryptoHunter World
In September 2024, IOST participated in a $2.8 million private funding round for CryptoHunter World, a GPS-based Web3 RPG game. The game allows players to collect NFT creatures (Cryptids), battle in real-world locations, and earn tokens—all while retaining full ownership of in-game assets via blockchain.
This partnership highlights IOST’s growing influence in the gaming sector, where low-latency transactions and scalable infrastructure are critical.
PayFi + DePIN Governance Proposal
Launched in late 2024, the IOST PayFi + DePIN governance proposal aims to unify payment infrastructure with decentralized physical networks (DePIN). Key goals include:
- Upgrading token utility across payment gateways
- Expanding node networks for data sharing and bandwidth provisioning
- Setting aggressive growth targets for 2025
By integrating financial services with physical infrastructure incentives, IOST is building a self-sustaining Web3 economy.
