Programmable scarcity enabled by tokens includes:

1. _Fixed supply_: Token supply can be capped, creating scarcity.

2. _Deflationary models_: Token supply can be programmed to decrease over time.

3. _Inflationary models_: Token supply can be programmed to increase at a controlled rate.

4. _Dynamic supply adjustment_: Token supply can be adjusted based on market conditions.

5. _Token burning_: Tokens can be permanently destroyed, reducing supply.

6. _Token locking_: Tokens can be temporarily or permanently locked, reducing circulating supply.

7. _Smart contract management_: Token supply can be managed and adjusted through smart contracts.

8. _Decentralized governance_: Token holders can vote on supply management decisions.

9. _Algorithmic supply management_: Token supply can be managed by algorithms, ensuring predictable scarcity.

10. _Scarcity incentives_: Programmable scarcity can create incentives for token holders and users.

Programmable scarcity allows for innovative token economics, enabling projects to create unique incentives, manage supply and demand, and achieve specific economic goals, such as stimulating adoption or rewarding holders.
