BFT (Byzantine Fault Tolerance) 是一個「容錯算法」，近年來因為被應用在 Blockchain 領域，做為一種共識演算法，因此得到許多青睞。BFT 有著許多 variants （變異）版本，比較常見的有：

  • PBFT（用於 Hyperledger Fabric v0.6 開源版本）
  • SBFT（IBM 提出、目前用於 Hyperledger Fabric v1.0）
  • dBFT（Antshares 區塊鏈就是一個知名案例）
  • 混合式 BFT

混合式 BFT 最常見的是加入了 Sensor-fusion 演算法，也就是 BFT variants + sensor-fusion = Hybrid BFT。混合式 BFT 最早被應用在 RTOS 實作中，在我的 Flowchain 計畫裡，則是將混合式 BFT 應用在 IoT Blockchain 技術裡。
