When to Use PBFT
Ideal Scenarios
- • Known, vetted validator set
- • Need instant finality
- • High throughput required
- • Enterprise or consortium networks
- • Low latency critical
- • Regulatory compliance needed
Not Recommended For
- • Fully public networks
- • Anonymous participants
- • Very large validator sets (100+)
- • High node churn
- • Completely trustless environment
- • Maximum decentralization needed
Enterprise Success Story
Walmart uses Hyperledger Fabric (PBFT-based) to track food supply chains. In 2018, they reduced the time to trace mangoes from farm to store from 7 days to 2.2 seconds. The system now tracks over 25 product lines across 5 suppliers, processing thousands of transactions per day with instant finality.
