# Features
Feature is a functionality added to the Waves blockchain during a new release.
Features have names and unique IDs and can be enabled by setting supported parameter in the features section of the node configuration file. For details see Features Settings section of the Node Configuration article.
You can get the list of features and their statuses using the GET /activation/status operation of Node REST API.

# Feature Status
Each feature can have one of the three statuses:
- Voting
- Approved
- Activated
# Activation of New Features
Feature activation protocol is a procedure according to which a new feature gets activated, i.e. it gets the "activated" status.
Activation process consists of voting and activation. Each mining node (which generates blocks) can vote for a new feature by having the voting parameter set in its configuration file. Such node generates blocks that contain the vote for the feature. See example and more details in Activation Protocol article.
If there are not less than 8000 blocks on Mainnet (2700 on Testnet and 40 on Stagenet) with support of the feature during the voting period (every 10000 blocks on Mainnet, 3000 on Testnet and 100 on Stagenet), the feature gets "approved" status on the blockchain. An "approved" feature becomes "activated" after another 10000 blocks on Mainnet (3000 on Testnet and 100 on Stagenet). Then the feature starts working and all the nodes which can not support such feature (old versions) stop.
For more details see Activation protocol article.
