Pi Network uses a low-energy consensus method, specifically the Stellar Consensus Protocol (SCP) and Federated Byzantine Agreement (FBA). This approach allows for secure and efficient transaction validation without relying on energy-intensive proof-of-work (PoW) algorithms like those used in Bitcoin or Ethereum mining ¹.
*Key Features of Pi Network's Consensus Method
- *Low Energy Consumption*: Pi Network's consensus algorithm doesn't require significant computational resources or energy consumption, making it accessible to mobile devices.
- *Stellar Consensus Protocol (SCP)*: SCP is a consensus algorithm designed to ensure transaction security while improving processing speed.
- *Federated Byzantine Agreement (FBA)*: FBA enables nodes to form quorums and exchange messages based on a trust graph, achieving consensus without energy-intensive computations.
- *Security Circles*: Users can add trusted friends or family members to their security circle, enhancing network security and facilitating transaction validation ².
*How Pi Network's Consensus Method Works
1. *Node Formation*: Nodes are formed by users running Pi Network node software on their computers.
2. *Quorum Formation*: Nodes form quorums and exchange messages based on the trust graph.
3. *Consensus Achievement*: Nodes achieve consensus on transaction validation through the SCP and FBA algorithms.
4. *Blockchain Maintenance*: Nodes maintain the integrity of the blockchain, validating transactions and ensuring network security ³.
