Post-Quantum Security

Built for the quantum era.

Quantum computers pose a real challenge to classical cryptography. KaiChain was designed from day one using NIST's post-quantum standards — so your assets are protected regardless of what the future holds.

⚛️
Shor's Algorithm
Shor's algorithm can break classical ECDSA signatures. ML-DSA-65 lattice cryptography is immune.
Classical ECDSA: At Risk
🔐
ML-DSA-65 Lattices
Based on Module Learning With Errors — no known quantum algorithm can solve it.
KaiChain: Immune
🌊
Grover's Algorithm
Grover's algorithm weakens SHA-256. KaiChain uses SHA-3/256 which retains full 128-bit post-quantum security.

01 — CRYPTOGRAPHY
🔑
ML-DSA-65 Signatures
1952-byte public keys, 3309-byte signatures. NIST FIPS 204. Lattice-based — mathematically unbreakable by quantum computers.
02 — CONSENSUS
⛏️
SHA-3 Proof of Work
Keccak-256 hashing. Mine KAI on any computer. 50 KAI block reward halves every 10 blocks — just like Bitcoin.
03 — NETWORK
🌐
Decentralised P2P
Automatic peer discovery, chain sync, transaction gossip. Fork resolution via Nakamoto longest-chain rule.
04 — WALLET
🔒
AES-256 Encrypted
24-word seed phrase. AES-256-GCM with PBKDF2 at 200,000 iterations. Password required before every transaction.
05 — SECURITY
🛡️
Production Security
Rate limiting, DDoS protection, input validation, API key auth, secure headers. Every attack vector considered.
06 — ECONOMY
💎
Fixed Supply
100,000,000 KAI hard cap. No pre-mine. No VC allocation. No founder tokens. Every KAI earned through mining.
Comparison

How we compare.

The post-quantum blockchain landscape is evolving fast. Here is where every major chain stands today — and where KaiChain fits in.

Note: Ethereum, Solana, QRL and Sui are all strong projects. This table focuses on one dimension only — post-quantum cryptography readiness. KaiChain was built from the ground up with the latest NIST FIPS 204 standard. We respect all of these networks.

💡
No Pre-mine. No VCs. No Founders Allocation.
Every single KAI in existence is earned through proof-of-work mining. No pre-allocated tokens, no investor rounds, no team wallets. KaiChain belongs entirely to those who mine and use it.
