This limited-edition release confirms demand for on-chain, user-owned decentralized identity.

SINGAPORE, June 19, 2025 — IOST, a modular blockchain platform focused on compliant real-world asset tokenization and decentralized identity, has finished deploying its initial 1,000 Signet Rings. These are biometric-enabled wearable credentials designed to link physical presence to on-chain identity.

Fully claimed, this limited distribution attracted over 12,000 registrations, indicating significant interest in decentralized identity tools that offer verifiability, privacy preservation, and practical real-world application.

The Signet Ring is more than just a wearable device; it represents IOST’s foundational step in establishing an identity layer for the modular Web3 ecosystem. Equipped with biometric verification and linked to each user’s on-chain credentials, it serves as a gateway to IOST’s expanding array of decentralized ID use cases. Its users include advanced DeFi participants with portfolios exceeding $10,000, individuals seeking airdrop incentives, and Web3 fund managers looking for strategic asset allocation tools.

Significance

Digital identity is rapidly becoming crucial for the future of regulated DeFi, tokenized real-world assets, and human-AI interactions. The Signet Ring program is actively testing real-world demand for essential infrastructure components:

  • Wear-to-Earn: This program offers rewards linked to verifiable biometric activity and physical participation.
  • NFT Credentials: The rings function as both referral and access passes, which are tradable on the blockchain.
  • Portable Identity: They provide solutions for Know Your Customer (KYC) alternatives, secure health data storage, and proof-of-personhood.

Under the hood, biometric signatures captured by the Signet Ring are processed via its companion application using zero-knowledge proofs and fully homomorphic encryption. Raw biometric data—such as heartbeat patterns utilized for HRV analysis—remains encrypted locally, while the app generates verifiable proofs for on-chain identity attestation. This foundational identity primitive plays a crucial role in IOST’s broader RWA infrastructure, facilitating compliant tokenization of real-world assets with confirmed human presence.

“This is not merchandise; it’s infrastructure,” stated Blake Jeong, CEO of IOST. He added, “We limited the initial batch to 1,000 units to gauge genuine demand, and the response confirms it exists.”

Future Plans

Following the complete distribution and widespread use of the rings across various regions, IOST is now initiating the subsequent phase:

  • Biometric Rewards: Users of the rings will gain increasing advantages linked to verified activity.
  • Credential Trading: Referral and access NFTs associated with the rings will become available on secondary markets.
  • Ecosystem Access: Ring owners will receive preferential access to decentralized applications (dApps) requiring identity, enhanced staking multipliers, and governance-weighted distribution events.

To further broaden its biometric integration capabilities, IOST has formed a partnership with StressWatch, a leading health monitoring company with over 10 million users. Additionally, the foundation is currently engaged in discussions with medical device manufacturers to expand identity modules to incorporate additional biometric data inputs.

The Signet Ring program establishes the basis for IOST’s long-term objective: to function as a fundamental layer for the globe’s most seamless and compliant real-world asset (RWA) infrastructure. With AI agents increasingly representing users in digital marketplaces, a verifiable human identity will be essential infrastructure for the $300 trillion RWA economy.

As the tokenization framework evolves, identity is becoming a central layer. IOST’s pilot project demonstrates the practical application, rather than just theoretical concept, of biometric credentials within a modular, compliant Web3 environment.

ABOUT IOST

IOST provides a modular infrastructure for real-world assets (RWA), built upon high-performance Layer 1 (L1) and EVM-compatible subnets. Since 2018, it has processed more than 961 million transactions with no downtime, enabling the scalable tokenization of assets such as bonds, real estate, and on-chain funds.

Currently, IOST operates a native mainnet and an EVM-compatible Layer 2, with intentions to develop permissionless subnets designed for specific asset classes. By 2028, IOST targets facilitating over $10 billion in tokenized assets, establishing itself as a premier portal for compliant digital economy yields.
