zkBob, a privacy solution on Polygon and Optimism with a stablecoin BOB, focuses on regular financial activities and integrates compliance features, such as deposit limits and optional KYC, to offer secure and private transactions while preventing illicit activities.

zkBob

zkBob has spent more than 2 years in R&D working with researchers at ZeroPool to create a secure privacy solution that also offers compliance features for users.

zkBob launched last September on Polygon, and the 2nd zkBob pool was just released on Optimism! zkBOB uses the BOB stablecoin for transactions, creating a stable payments environment designed to support regular use cases like:

  • Salaries
  • Single-click payments
  • Donations, grants, and fundraising
  • DAO contributor disbursements

Privacy at risk

As we know, we are at risk of losing our privacy rights, and several prominent privacy applications have been sanctioned or have elected to sunset recently.

zkBob is approaching this problem from a different angle. Rather than a free-for-all that can encourage illicit activity, zkBob proactively prevents illicit activity through several compliance features.

Compliance features

Compliance features baked into zkBob include:

  • Deposit limits to prevent large sums from coming in at once (ie from bridge hacks).
  • Optional KYC to increase deposit limits.
  • Integration with TRM to check and reject suspicious wallets
  • Ability for users to provide transaction history if requested (this is private information that can only be viewed by the sender/receiver)
  • Additional exploration into compliance features that prevent illicit activity while protecting individual privacy.

zkBob Traction

zkBob is developing internal use cases and attracting external use cases where privacy makes sense, and onboarding more users and developers to the open-source codebase.

zkBob continues to gain traction and usage, and current usage stats can be seen on the Dune analytics dashboard at https://dune.com/maxaleks/zkbob.
