Aleo is the first platform to offer fully private apps.Aleo achieves this by using decentralized systems and zero-knowledge cryptography to protect user data online.

Becoming zero-knowledge.

Unlike web technologies today, zero-knowledge cryptography presents a foundation for the web that is secure, compliant, and fair. New web standards built upon this technology offer users choice and will mitigate the impact of data breaches.

First, zero-knowledge makes web services secure.

For example, rather than risk leaking a user’s password, users can now hash their password (with salt and pepper) on-device, without ever having to send their password over to any web service. Not only does this keep user data on-device, it reduces access control overhead and eases the legal responsibility that web services must bear today.

Second, zero-knowledge makes web services compliant.

For example, brokerages today not only learn the complete history of a user’s transactions, they also learn when a user performs a trade. Access to this data allows brokerages to sell valuable information to third parties, choose to deny service to specific users, and even front run their own users on exchange. This is a serious and unsolved problem. Users should not have to hope their brokerage behaves honestly, and regulators should have proof that brokerages adhere to their standards.

Third, zero-knowledge makes web services fair.

Web services should not have to possess users’ data in order to provide a valuable experience. Users should be able to interact with web services blind to their personal information. For example, if a brokerage cannot learn their users’ data, they cannot target any one user — whether to deny them service or offer an unfair price. The choice of handing data over should be one that users get to make.

This is merely a taste of what Aleo is building.
