Project ideas from Hacker News discussions.

Opening up 'Zero-Knowledge Proof' technology to promote privacy in age assurance

📝 Discussion Summary (Click to expand)

Theme 1 – Legislative inertia

"Not really any point since US legislators aren't motivated by the interests of regular people." – dboreham
The discussion repeatedly points out that pushing for age‑verification laws is pointless without political will to listen to the public.

Theme 2 – Age‑assurance is a surveillance vector

"The bill doesn't even make it clear whether briefing their solicitor about the request is legal ... There's no safe app, so we should completely resist all attempts to do things the government could restrict, leak or misuse." – protocolture
Users argue that “age verification” is really a gateway for governments and corporations to collect and weapon‑ise personal data.

Theme 3 – Technical skepticism of ZKP solutions

"But if they reveal nothing, isn't it wide open for abuse? Couldn't one over‑18‑person's proof become everyone's proof?" – Aurornis
The consensus is that zero‑knowledge proofs remain vulnerable to token reuse, collusion, and central‑authority dependencies, making them a poor foundation for privacy‑preserving age checks.

Theme 4 – Public support for bans vs. imperfect regulation

"77% of the Australian population were in support of 'Proposed ban on social media for children under 16'." – Gigachad
While polls show strong public backing for restricting kids’ access, commentators stress that bans alone are blunt tools and that better, less intrusive solutions are needed.


🚀 Project Ideas

ZeroKnowledge AgeGate

Summary

  • A browser extension that lets users generate and present zero‑knowledge proofs of age (≥18) without ever revealing personal data to websites.
  • Enables private access to age‑restricted content while staying anonymous.

Details

Key Value
Target Audience Privacy‑conscious internet users, journalists, activists in heavily surveilled regimes
Core Feature On‑device generation and verification of age proofs using ZKP libraries
Tech Stack WebExtensions (JS/TS), circom/gnark, IndexedDB, optional hardware wallet integration
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters repeatedly stress that “perfect anonymity is impossible” but want a pragmatic middle ground; this extension offers a “privacy‑first” alternative to mandatory ID portals.
  • Could spark discussion on enforceability and potential for abuse.

LegisLens

Summary

  • A collaborative platform where HN members can collectively annotate and summarize pending age‑verification bills, turning raw legislative text into bite‑size talking points.
  • Turns complex policy proposals into crowd‑sourced, shareable PDFs for advocacy.

Details

Key Value
Target Audience Activist HN members, policy wonks, legislative staffers
Core Feature AI‑drafted bill summaries with annotated highlights and suggested opposition arguments
Tech Stack Node/Go backend, LLM fine‑tuned on legal texts, Markdown front‑end, bill database
Difficulty Low
Monetization Revenue-ready: $5/mo subscription for premium templates

Notes

  • Directly answers frequent calls to “inform legislators about zero‑knowledge proofs” by providing ready‑made evidence packages.
  • Generates user‑generated content, fostering discussion among HN participants.

CredentialLeakWatch

Summary

  • A service that continuously monitors the issuance and revocation of digital age‑verification credentials, alerting users if a credential appears on data‑leak databases.
  • Prevents reuse of stolen or forged verification tokens.

Details

Key Value
Target Audience Individuals subject to age‑verification mandates, developers of ZKP wallets
Core Feature Real‑time credential health dashboard and revocation API
Tech Stack Python backend, Elasticsearch, React UI, WebPush notifications
Difficulty Medium
Monetization Hobby

Notes

  • Directly addresses HN concerns about how to stop tokens from being copied or reused, providing a concrete mitigation.
  • Sparks conversation about cryptographic hygiene and future abuse vectors.

PrivacyLedger

Summary

  • A decentralized app that lets users self‑attest their age and issue verifiable proofs stored on a public blockchain, avoiding centralized authorities.
  • Enables peer‑to‑peer verification without relying on any corporate or government verifier.

Details

Key Value
Target Audience Crypto enthusiasts, privacy advocates, decentralized identity developers
Core Feature Issuance and verification of self‑signed age attestations using publicly verifiable credentials (e.g., EIP‑5193)
Tech Stack Solidity smart contracts, IPFS storage, Web3.js front‑end, ZK aggregation middleware
Difficulty High
Monetization Revenue-ready: $0.01 per issuance

Notes

  • Mirrors HN frustration with “government‑issued credits” and seeks an open‑source alternative, promising lively debate on security vs. usability trade‑offs.
