Mainnet launched last september.

Unlike competitors, HPB relies on a hardware solution, already deployed
The Blockchain Offload Engine (BOE)

I view it as ASICS mining / GPU for scalability. It won't achieve 1M tps next week but you won't achieve faster speed than HPB without their hardware imo.


Current performance: 5000 TPS (10k within China), 150 nodes, 6s avg block time.
