Decentralised web cookies
Doughnuts are digital certificates suited for the blockchain and decentralised era.
With Doughnuts users can control and own their data, decide when and to whom would they like to grant permissions to access it, all without relying on a central server.
The dangers of private key transmission, along with the high consumer demand for good UX and ideal security, requires a new system. But it’s not hardware devices and identity contracts.
Doughnuts solve this problem. The concept is simple, yet powerful, enabling a classic ‘centralised’ UX on trustless, decentralised technologies.

Powerful alternative login mechanism
Doughnuts make it possible to share access or grant tiered permissions to a DeFi DApp in a secure way without having to use hardware authentication device. Doughnuts can allow a flow similar to single sign on solutions without being exposed to an authenticating server attack.
Imagine sharing game assets right between players via seamless permissions management, you’ll also be able to design the scenario for when you want a user to be able to revoke permissions.
Doughnuts can be used to authenticate login as form of 2fa or multifactor authentication setup without relying on authentication by central server or hardware device.
