Public testnet running Proof-of-Bandwidth, sub-second BFT finality, and ML-DSA-65 signatures. Open to validators. Free to send.
Five Stake-Proportional Validation Tiers (SPVT). Higher stake earns more reward weight, capped at 3.0×. A validator can never attest a transaction larger than its own stake.
| Tier | Minimum stake | Reward multiplier | Validation cap |
|---|---|---|---|
| Micro | 1,000 UMX | 1.0× | ≤ 1,000 UMX / tx |
| Small | 2,500 UMX | 1.4× | ≤ 2,500 UMX / tx |
| Mid | 7,500 UMX | 1.9× | ≤ 7,500 UMX / tx |
| Large | 15,000 UMX | 2.4× | ≤ 15,000 UMX / tx |
| Mega | 25,000+ UMX | 3.0× | unlimited |
Anyone with capacity can validate. Stake from 1,000 UMX, hold up your bandwidth obligations, earn proportional rewards.
