Decentralized Auth, Identity & Storage

BlockSurvey uses Stacks Blockchain for Decentralized Identity/Account(DID). BlockSurvey uses Stacks API for identity, auth, and storage management. This is the core working system that enables true ownership of the identity and data for you.

Stacks Blockchain

Bob is in complete control of his identity and data all the time. It is his digital right. He gets a unique identity and private storage(GAIA), which only he can access. He holds his keys for his identity and storage. Not BlockSurvey or Stacks Blockchain.

Respondents are anonymous

BlockSurvey does not use trackers, cookies, or fingerprints. All respondents/data providers, like Alice, can remain anonymous by default unless they choose to voluntarily disclose their identity in the questionnaire by filling it out their personally identifiable information.

End-to-end encryption

Alice's and other respondents' data is encrypted with Bob's public key and sent to BlockSurvey's temporary data store for collection. When Bob sees his responses, they are collected from BlockSurvey and transferred to his private storage (GAIA). The encryption happens at the client side / browser and not at the server side.

Zero knowledge

All of Bob's data stored in BlockSurvey is encrypted using Bob's public key. BlockSurvey has no knowledge of his data and cannot understand any of it. Only Bob's key can unlock and see the data.

Private analytics

Bob, as a data collector, will collect Alice's data from BlockSurvey and store it in his private storage. Once completed, he will be able to decrypt the data and view it in the form of results and analytics using his keys in browser.
