Questbook is building the tech stack for a pseudonymous future of work. Hundreds of builders apply for grants on https://questbook.app every month. Many of them ask to apply pseudonymously to save themselves from discrimination based on their sex, geography, religion and race. Some also want to hide their real identity to avoid getting in trouble with their day job.

We are building the tech stack that allows the users to use their credentials that they've accrued over time on services like Github, Twitter or their employer's internal websites - all so without revealing their real identity.

About the role

We are building a privacy preserving proof protocol to generate proof of credentials for users. We do so using the TLS session keys and a consensus mechanism. (Please contact me for early versions of the whitepaper)

The closest cousins for what we're building are https://deco.works and https://tlsnotary.org

You'll be best fit if

  • Proficient with cryptography involved in TLS, HTTPS, SSL
  • Able to write production ready code
  • Willing to work on low level networking stack
  • Node, Go experience

Sample projects

  • Implement a TLS handshake using nodejs
  • Build a proxy server that validates the HTTP headers' validity

You will be

  • Building protocol level libraries
  • Testing and debugging libraries
  • Theoretically proving security
  • Researching better implementations and expansions to the protocol
