# Node Evolution

## Evolution

An investor wishing to make use of this feature would utilize their rewards to compound more $PARA tokens in node.

Once a sufficient number of tokens has been accumulated, the investor is able to mint PARAVERSE NFT NODE using the accumulated $PARA form TIER 4 PARANODE. As a result, the investor unlocks maximum possibility of PARAVERSE system allowing them to earn more without altering the value of their holdings, which means this action is a strict upgrade with no downside.

Due to the nature of the system, utilizing the upgrade function will require a small BNB fee. This feature will go live several days after the official launch of the nodes.

**On evolution 100% of locked tokens in ParaNode will be burned**
