The Web3 ecosystem is continuously evolving, and with it comes the need for enhanced privacy and security solutions. Oasis Network, a privacy-focused decentralized network, is at the forefront of this change, empowering developers to build privacy-preserving applications across any EVM chain. The Oasis Privacy Layer is ushering in a new era of utility for Web3 by enabling a range of use cases that require customizable privacy.

Decentralized Identity

One of the most significant use cases for privacy in Web3 is decentralized identity. Users can securely store and manage their digital identities on the Oasis Network, granting access to various services without disclosing sensitive information. This not only empowers individuals to control their personal data but also mitigates the risk of identity theft.

Confidential Decentralized Finance (DeFi)

Confidential DeFi is another promising use case. Privacy-preserving DeFi allows users to interact with financial services without revealing their identity or financial data. By ensuring privacy and security, this approach reduces the potential for malicious actors, such as front-runners who exploit trading parameters for personal gain.

Private Data Marketplaces

The Oasis Privacy Layer also facilitates the creation of private data marketplaces. Users can monetize their personal data by sharing it with data consumers in a controlled, privacy-preserving manner. This exchange promotes a fair value exchange between data owners and businesses while ensuring users’ privacy.

Medical Data Sharing

Customizable privacy in medical data sharing is a game-changer for the healthcare industry. The Oasis Privacy Layer enables secure and compliant sharing of sensitive health records among patients, doctors, and researchers, promoting better health outcomes while preserving patient privacy.

Decentralized Autonomous Organizations (DAOs)

DAOs can also benefit from the Oasis Privacy Layer. By allowing members to vote privately without revealing their identity or choices, DAOs can foster a more democratic environment, free from voter bias. To maintain transparency, vote results and individual votes can be revealed after the voting process.


The NFT market can also benefit from privacy features. By hiding certain aspects of NFT auctions, such as bid amounts or end time, the Oasis Privacy Layer can promote fairer auction mechanisms and avoid issues like gas wars that plague current NFT auction systems.


The Oasis Privacy Layer can revolutionize gaming in the Web3 world. Most games have private components; for example, a card game assumes that one player cannot see other players’ cards. With the Oasis Privacy Layer, all elements of a Web3 game can be kept private on-chain, eliminating the need to move to off-chain environments.


Decentralized social media platforms can leverage customizable privacy to protect user data and content preferences. By utilizing the Oasis Privacy Layer, users can maintain control over their digital footprint while benefiting from personalized content recommendations.

In summary, the Oasis Privacy Layer is propelling Web3 forward into a new era of utility. By isolating sensitive data from the rest of the system with TEEs (Trusted Execution Environments), Oasis technology allows Web3 applications to perform sensitive operations without compromising user privacy. The Oasis Privacy Layer unlocks a wide range of privacy-centric use cases for Web3, enabling a more secure, private, and scalable future for decentralized technologies.
