Post-quantum blockchain · Now live

Built to outlast quantum.

Bitcoin and Ethereum will be broken by quantum computers. KaiChain was built with that day in mind — secured by ML-DSA-65, the NIST FIPS 204 standard. The only blockchain designed to survive.

The Quantum Threat

Your crypto won't survive.

Quantum computers running Shor's algorithm can break Bitcoin and Ethereum's ECDSA signatures. KaiChain was built to be the alternative.

⚛️
Shor's Algorithm
Breaks ECDSA used by Bitcoin and Ethereum. Private keys derivable from public keys.
Bitcoin / Ethereum: Vulnerable
🔐
ML-DSA-65 Lattices
Based on Module Learning With Errors — no known quantum algorithm can solve it.
KaiChain: Immune
🌊
Grover's Algorithm
Weakens SHA-256. KaiChain's SHA-3 retains full 128-bit post-quantum security.
KaiChain: Resistant

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.

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.
Getting Started

Four steps.

01
Create your wallet
Visit wallet.kaichain.xyz. Choose a password. Write down your 24-word recovery phrase. Your keypair is generated in your browser — your secret key never leaves your device.
→ wallet.kaichain.xyz
02
Get KAI
Run a KaiChain node to mine blocks and earn KAI, or receive KAI from another wallet holder. Block rewards start at 50 KAI.
python3 api/node.py
03
Send KAI
Enter a recipient address and amount. Review the summary. Enter your password to confirm. Signed with ML-DSA-65 and broadcast to the network.
Confirms in minutes · Fee: 0.001 KAI min
04
Verify everything
Every transaction, block, and balance is publicly verifiable on the KaiChain block explorer. Full transparency, always.
