關於Avanlanche共識算法家族的論文在這裏html
Avanlanche共識算法家族: Slush, Snowflake,Snowball and Avalanchenode
Slush有如下屬性: 算法
Slush不是拜占庭算法安全
Snowflake給每個節點加了一個計數器。網絡
1. 每一個節點有一個計數器
2. 每次顏色改變的時候,節點的技術器歸零
3. Upon every successful query that yields k responses
for the same color as the node, the node increments cnt.ide
Snowflake算法的計數器是暫時的,每一次顏色的轉換就會致使計數器歸零。Snowball引入了一個信心計數(Confidence Counter)區塊鏈
雪崩協議結合了非拜占庭共識算法和中本聰共識算法的特徵,優點明顯:spa
Snowball的圖形化演示:https://tedyin.com/archive/snow-bft-demo/ 兩種顏色表明兩種不一樣的初始值,最後會收斂到某一種顏色上。視頻
這裏有會議的完整視頻哦(也能夠回放)第三位分享嘉賓就是來自Avalanche(AVA)的Kevin(20分鐘左右)
