A decentralised password manager

BlockLock

BlockLock was created during the Ethdam 2024 Hackathon.

Our purpose

BlockLock attempts to bridge the gap between traditional web2 user experience and the advantages of using a confidential and decentralised environment.

What is BlockLock

BlockLock is a web extension that works similarly to web2 password manager plugins like 1Pass, however the difference is that data is stored on chain. Oasis was a great fit for the project with Sapphire's encrypted storage of data & private execution environment to maintain confidentiality.
