# 3.5 Consensus Protocol / Token Issuance Model

QUBI utilizes a consensus protocol and token issuance model that prioritize efficiency, security, and scalability. Through a combination of Proof of Stake (PoS) and Byzantine Fault Tolerance (BFT) consensus mechanisms, QUBI ensures fast transaction processing and robust network security. The token issuance model may include mechanisms such as block rewards, transaction fees, and validator rewards to incentivize network participation and maintain consensus integrity.
