Most blockchains depend on a patchwork of outdated or vulnerable cryptography...
Xcoin takes a fundamentally different approach...
The technologies below are not experimental...
Together, they form the foundation of a system...
| Component | Purpose | Why It Matters |
|---|---|---|
| zk-STARKs | Private, trustless transaction proofs | No trusted setup, quantum-secure, scalable privacy |
| Halo 2 | Hides transaction amounts | Efficient range proofs without exposing values |
| Ring Signatures | Hides the sender | Sender anonymity within a group—unlinkable and untraceable |
| Stealth Addresses | Hides the receiver | One-time, invisible addresses for every transaction |
| SPHINCS+ | Digital signatures (post-quantum) | Approved by NIST; secures messages and transactions from quantum decryption |
| WOTS+ | One-time signature scheme | Simple, secure, and quantum-resistant; foundation for SPHINCS+ |
| Poseidon Hash | Fast hash function for zero-knowledge circuits | Built for zk-proofs—smaller, faster, and cheaper than traditional hashes |
| Keccak-512 | General-purpose hashing | Secure against quantum attacks; used in broader system operations |
| zk-Rollups | Bundles many transactions into one proof | Enables high throughput, low fees, and minimal on-chain data |
| DAG Structure | Transaction ordering and scalability | Parallel validation without mining—scales to millions of users |
| View Keys | Optional, read-only transparency | Lets users prove specific data without compromising privacy |
| No Trusted Setup | System integrity | Removes centralized risk—no hidden secrets, no single point of failure |
| AES-512 | Proprietary encryption for maximum security | Reinforces sensitive operations beyond standard cryptographic safeguards |
Xcoin is the only blockchain that combines all of these cryptographic building blocks into a single, unified protocol...
This architecture goes beyond competing with existing blockchains — it renders all others obsolete.
Xcoin is the first chain designed from scratch to resist surveillance, resist quantum attacks, and scale to billions—without tradeoffs.
