Introducing Seal: Revolutionizing Data Privacy and Access Control on Walrus Mainnet

Grand Cayman, Cayman Islands, September 3rd, 2025, Chainwire
Seal is now available with Walrus Mainnet, offering encryption and access control for anyone building on the protocol. As the data layer for Web3, Walrus already provides decentralized infrastructure for data storage, availability, and programmability. With the launch of Seal, Walrus now delivers a solution for integrating programmable data access into any app at any scale.
Web3’s transparency means data is public by default. For many, that is a benefit, while others require privacy or access controls. Walrus with Seal enables builders to create products that not only require verifiable data but also data privacy, fine-grained access, and secured sharing. A whole world of Web3 apps becomes possible when these technologies work together.
Making privacy part of public infrastructure
Transparency is the core ethos of Web3, but the idea that your data is visible to everyone can present challenges for builders and users alike. For those who need to manage potentially sensitive data, it’s a nonstarter. Anyone who wants to keep data confidential either has to use a centralized service or build a custom setup–not only time-consuming and expensive, but also a barrier to entry for newcomers exploring onchain data management solutions.
Thanks to the launch of Seal, Walrus is the first decentralized data platform to natively offer onchain access control. Developers can now protect sensitive data, define who can access it, and enforce those rules entirely onchain.
Unlocking transformative use cases
With the addition of programmable data access control, Walrus now enables entirely new categories of applications that were previously impossible in decentralized environments. For example:
- AI Dataset Marketplaces: Organizations can now share proprietary training data or fine-tuned models while enforcing strict access policies. Data providers can monetize their assets without losing control, creating new revenue streams in the AI economy.
- Token-Gated Subscription Services: Premium content such as exclusive podcast episodes, videos, or educational materials can be encrypted and made accessible only to verified subscribers, enabling sustainable creator economies on Web3.
- Dynamic Gaming Content: Game developers can reveal encrypted in-game content, story elements, or assets only when players achieve specific milestones, creating more engaging and interactive gaming experiences.
Partners are driving real-world adoption
Dozens of Walrus-powered projects are already using Seal, demonstrating the immediate practical value of onchain encryption and access control. Examples include:
Tokenizing AI Infrastructure
Inflectiv is building a data platform for AI that uses Walrus with Seal to gate and tokenize datasets. This allows contributors to protect and monetize their data while providing developers and enterprises with secure, trusted assets for AI and agent-driven applications.
Trustless Gaming Mechanics
Vendetta is a fully onchain multiplayer strategy game that leverages Walrus with Seal to secure in-game data and mechanics. Players gain true ownership of their progress and assets while competing in skill-based, tamper-proof battles within a transparent and secure game economy.
Securing AI Agent Infrastructure
TensorBlock is building a decentralized AI platform that uses Walrus with Seal to secure models, memory, and datasets. This lets contributors protect and monetize their data, making AI accessible and democratic for all.
A full stack for decentralized data
Sui and Walrus, now with Seal, aim to accelerate the transition from Web2 to Web3, creating a comprehensive infrastructure stack for the decentralized internet. Sui provides the high-performance blockchain foundation. Walrus with Seal delivers scalable data management, availability, and access control essential for enterprise adoption. This integrated approach addresses the full spectrum of requirements for building sophisticated Web3 applications that can compete with Web2 counterparts.
The momentum for building full-stack apps continues to grow. OneFootball plans to use Walrus with Seal to deliver content with built-in rights management, ensuring it reaches the right audiences while protecting intellectual property. Watrfall, the Ron Perlman-led fan-funded studio, is using Walrus with Seal to unlock new models for distribution, ownership, and fan engagement. Alkimi is already processing over 25 million ad impressions per day using Walrus, with Seal keeping confidential client data secure while maintaining the transparency benefits of blockchain technology.
The future of Web3 apps relies upon data that’s intelligently controlled, privately managed, and enterprise-ready. That’s why it will be built with Walrus and Sui.

Walrus Mainnet Launches Seal: A Game-Changer for Web3 Data Privacy and Access Control
Grand Cayman, Cayman Islands, September 3rd, 2025 — Chainwire
In a groundbreaking development for the decentralized web, Walrus has officially launched Seal, a powerful new feature that integrates encryption and access control into its Mainnet. This innovative addition positions Walrus as the first decentralized data platform to offer on-chain access control, enabling developers to build applications that require both data privacy and programmability.
As the data layer for Web3, Walrus already provides a robust infrastructure for data storage and availability. With the introduction of Seal, it now empowers builders to create applications that not only require verifiable data but also enforce fine-grained access controls. This dual capability opens the door to a myriad of new possibilities in the Web3 ecosystem.
The Challenge of Transparency in Web3
While transparency is a core principle of Web3, it can pose challenges for users and developers who need to manage sensitive data. Traditionally, those seeking privacy have had to resort to centralized services or custom solutions, which can be both costly and time-consuming. Seal changes the game by allowing developers to protect sensitive information and define access rules entirely on-chain, making it easier for newcomers to navigate the complexities of on-chain data management.
Unlocking New Use Cases
The addition of programmable data access control is set to unlock transformative use cases that were previously unattainable in decentralized environments. Some notable applications include:
-
AI Dataset Marketplaces: Organizations can now share proprietary training data while enforcing strict access policies, allowing them to monetize their assets without sacrificing control.
-
Token-Gated Subscription Services: Creators can encrypt premium content, making it accessible only to verified subscribers, thus fostering sustainable creator economies on Web3.
-
Dynamic Gaming Content: Game developers can reveal encrypted in-game assets only when players achieve specific milestones, enhancing engagement and interactivity.
Real-World Adoption
The immediate practical value of Seal is already being demonstrated by numerous Walrus-powered projects. For instance:
-
Inflectiv is utilizing Walrus with Seal to create a data platform for AI that allows contributors to protect and monetize their datasets.
-
Vendetta, a fully on-chain multiplayer strategy game, leverages Seal to secure in-game data, providing players with true ownership of their assets.
-
TensorBlock is building a decentralized AI platform that uses Walrus with Seal to secure models and datasets, democratizing access to AI technologies.
A Comprehensive Infrastructure for Web3
Walrus, in conjunction with Sui, aims to accelerate the transition from Web2 to Web3 by creating a full-stack infrastructure for the decentralized internet. Sui provides the high-performance blockchain foundation, while Walrus with Seal delivers scalable data management and access control essential for enterprise adoption.
The momentum for building sophisticated Web3 applications continues to grow. Companies like OneFootball and Watrfall are already planning to utilize Walrus with Seal to enhance content distribution and fan engagement, while Alkimi processes over 25 million ad impressions daily, ensuring client data remains secure.
The Future of Web3 Apps
As the demand for intelligently controlled, privately managed, and enterprise-ready data solutions increases, Walrus and Sui are poised to lead the charge in shaping the future of Web3 applications. With Seal, the possibilities are limitless, paving the way for a new era of decentralized innovation.
