Architecture

Two layers.
One system.

KnexCoin holds value. Lumero moves it. Two assets, two jobs, designed to work together.

Layer 01

KnexCoin

NEX · The reserve
Gravity

Scarce, mineable, post-quantum. Audited and designed for long-term value preservation. NEX is what you hold — the asset that doesn't move much because it doesn't need to.

Layer 02

Lumero

UMX · The settlement layer
Velocity

Fast, mobile-first, backed by NEX. Built for remittances, merchants, payroll, and infrastructure finance. UMX is what moves — in seconds, anywhere, for very little.

How Lumero actually works.

Four design decisions that make payments fast, fair, and verifiable.

Block-lattice DAG

Every account has its own chain. Sends and receives are async — the sender writes a "send" block on their own chain; the receiver writes a "receive" block on theirs.

Transfers don't queue behind each other. The network scales with active accounts, not block size.

Sub-second finality

Once a stake-weighted majority of validators sign a block, it's settled. No "wait six confirmations." No probabilistic safety. A transaction is either final or rejected.

Proof-of-Bandwidth

Validators don't just stake capital — they prove they can actually carry traffic. A random function picks pairs of validators, they exchange known-size data, and independent observers measure the throughput.

  • Five staking tiers, from Micro (1,000 UMX) to Mega (25,000+ UMX)
  • Reward weighting tied to real network capacity, not just capital
  • Six-step anti-spoofing pipeline rejects loopback, replay, and wash exchanges
Post-quantum from genesis

ML-DSA-65 signatures — the NIST-standardized lattice signature scheme — are built in from day one. No retrofit. No quantum-flag day. Every address is PQ-native end-to-end.

Real capacity.
Not just staked capital.

Why every UMX is real.

Hard backing — not algorithmic, not promises. Reserves you can verify.

1.5× coverage

Every UMX is over-collateralized 1.5× in a basket reserve. Mints fail without coverage — new supply requires new backing first.

60% USD
25% EUR
15% Gold

The reserve basket is hard, transparent, and unamendable. Composition can only change through constitutional governance after mainnet stabilizes.

Floor redemption

Non-suspendable redemption right at floor price, enforced by protocol. The operator cannot pause, gate, or reorder redemptions — the rules can.
