 Dash Platform is a [Web3](https://en.wikipedia.org/wiki/Web3) technology stack for building decentralized applications on the Dash network. The two main architectural components, [Drive](../explanations/drive.md) and [DAPI](../explanations/dapi.md), turn the Dash P2P network into a cloud that developers can integrate with their applications.

+## Epoch
+
+An epoch is a fixed time period used to organize and manage blockchain operations. Dash Platform epochs are exactly 9.125 days (219 hours), resulting in 40 epochs (one [era](#era)) per year. Evonode reward payouts happen at the end of each epoch based on an evonode's validator set participation. The first epoch began at the genesis of Dash Platform.
+
+**Note:** Epochs are not determined by a certain number of blocks, but by a certain unix timestamp.
+
+## Era
+
+An era consists of 40 [epochs](#epoch) and equals approximately one year. At the end of an era, Dash Platform may optionally do additional accounting or reconfiguration.
