&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The cycle time is essentially the amount of time a node must wait before old transactions can be discarded. It defines the minimum amount of block history that a node is required to keep. Blocks are said to be &amp;quot;in view&amp;quot; while they are younger than the cycle time and out of view when older. There are several important reasons that nodes must keep a reasonable amount of minimum block history: it ensures that a reasonable size [[inversion database]] can be built upon [[network synchronization]], and it helps protect against the [[Weaknesses_and_attack_vectors | secret chain attack]].&lt;br /&gt;
&lt;br /&gt;
The cycle time used in [[Cryptonite]] is 1 week (10080 blocks at 1 block per minute).&lt;/div&gt;</summary>
