Openbands
Openbands is an anonymous and verified employee forum. Users can sign in with their work email and prove their company affiliation while preserving their identiy. After signing up users can participate in anonymous conversations. We are using Noir zkJWT library to prove a user is authorized to log into a company email. The user generated the proof client-side and submits it onchain, where it's verified and stored. Our aim to build a global community powered by truth and ran by professionals. In a future version, we want companies to post job listings. The fees collected for posting a job will be distributed to active contributors.

ORIUM
ORIUM is a privacy-first Layer 1 blockchain designed as digital cash. In a world where payments are monitored by default, ORIUM makes transactions private by design, ensuring that identities, balances, and transaction relationships are not exposed on public ledgers. Privacy is enforced through cryptography and zero-knowledge proofs, not through trust, policy, or intermediaries. ORIUM separates spending, reading, and proving into independent capabilities, giving users full control over disclosure. It operates as a neutral protocol, not an organization, restoring the core properties of money: fungibility, neutrality, and sovereignty. It can be used as an everyday payment method, with features like pay link and cash link, only on ORIUM.
