Privacy-Preserving Applications
INTMAX offers a new foundation for building applications where privacy is not a feature, but a guarantee. It enables developers to construct systems where no sensitive data touches the blockchain, and user interactions remain unlinkable, untraceable, and fully local—powered by zero-knowledge proofs and stateless architecture.
What You Can Build
- Private crypto transfers
- Anonymous donation platforms
- On-chain private voting or signaling
- ZK-based identity and credential apps
- Unlinkable subscriptions or access tokens
- Dark pools and private marketplaces
- Messaging or social protocols with hidden metadata
Why INTMAX?
Most privacy approaches in Web3 (mixers, shielded pools, encrypted mempools) rely on heavy infrastructure, trusted setups, or privacy that's optional. INTMAX is different:
| Property | INTMAX Guarantees |
|---|---|
| On-chain anonymity | ✅ No sender, recipient, or amount ever posted |
| Aggregator blindness | ✅ Aggregators see only salted hashes |
| Peer-to-peer disclosure only | ✅ Only recipient sees transaction details |
| Stateless, client-owned data | ✅ No global state exposure or leakage |
| Gas-efficient privacy | ✅ ~5 bytes onchain; cost doesn't scale with tx size |
🔄 Architecture Overview
- Users generate transactions locally and hash them before sending to aggregators.
- Aggregators build a Merkle tree, collect BLS signatures, and post a root (not the tx data) to the contract.
- Recipients receive Merkle paths + ZK proofs directly from senders and update local balances.
- Nothing sensitive ever touches the chain—not even encrypted payloads.
Developer Advantages
| Feature | Benefit |
|---|---|
| Default Unlinkability | No correlation between sender and recipient is exposed |
| No Need for Trusted Setup | Uses standard SNARKs and cryptographic commitments |
| No Central Coordinator | Anyone can aggregate; no centralized mixer/sequencer required |
| Gas-Optimized Privacy | Achieve strong privacy without paying extra in fees |
| Local State + Proofs | Users keep and manage their own state; no central index or registry |
Sample Applications
| Application | Description |
|---|---|
| Private Donations | Send ETH or tokens anonymously to any public address |
| Decentralized Whistleblowing | Tip systems with verifiable but unlinkable sender proofs |
| ZK Reputation | Build score systems where interactions are hidden |
| Pseudonymous Identity | Proofs of activity or holdings without revealing wallet links |
Integration Ideas
Use the INTMAX SDK to:
- Generate and verify ZK proofs for private transactions
- Build local client storage for tracking balance proofs
- Create privacy-first UI flows (e.g., show only proof-receipt and balance)
- Customize aggregators to enforce timing or batching constraints without compromising privacy
Key Takeaway
INTMAX offers a privacy stack native to Ethereum, but without revealing any information to the base layer or intermediaries. Whether you're building tools for dissidents, creators, activists, or just privacy-conscious users—INTMAX gives you the cryptographic primitives to make privacy standard, not optional.
