+## XENE Tokenomics
+XENE's tokenomics aim to build a token economy that supports Xenea in achieving the following key outcomes:
+
+- **Security**: An appropriate incentive model rewards protocol-based mining activity and encourages many ecosystem participants to operate secure nodes.
+- **Decentralization**: Future distributed nodes and communities contribute to ecosystem expansion and governance decisions.
+- **Sustainability**: The tokenomics are designed to encourage important Xenea processes, including block verification, in a sustainable manner.
+- **Ecosystem Development**: XENE is used as an incentive for dApp developers to build applications and services on Xenea.
