# SUI — Announcing Testnet Wave 2.

Validators, full node operators, delegators, app builders, and end users can all participate.

**Compared to the previous wave, Wave 2:**

*   Includes 2x the amount of validators
    
*   Enables anyone to run a full node
    
*   Allows builders to publish, test, and share their apps on Testnet.
    

**Wave 2 will test Sui’s tokenomics, including:**

*   Epoch management — operations like staking/unstaking + staking reward distribution all occur at epoch boundaries
    
*   Gas mechanism — validators will participate in setting the reference gas price + in monitoring validator performance.
    

Stake delegation and Proof-of-Stake mechanism — community members can participate in the Proof-of-Stake governance and receive stake rewards. Learn more in the Stake Delegation FAQ: here [https://t.co/XSmZdJ09E0](https://t.co/XSmZdJ09E0)

Testnet Wave 2 also features a pair of games designed to stress-test Sui’s tokenomics design and implementation. These games are designed to cause the validator stake distribution + reference gas price to substantially fluctuate from epoch to epoch to test edge cases.

The first is Frenemies, a competitive game that anyone will be able to play. It’s designed to generate chaotic movements in the validator stake distributions. We’ll share more details about Frenemies, including how to play, as soon as it launches!

The second game — Validator Game — exercises Sui’s reference gas price mechanism, and allows validators to adjust the minimum gas price in response to simulated external factors, such as SUI price fluctuations. Only validators can play this game in Testnet.

**A few reminders:**

*   Testnet SUI tokens + staking rewards are for testing purposes only, and do not have any associated monetary value
    
*   Wave 2 is testing an initial v1 of Sui tokenomics — but the accounting algorithm will continue to be fine-tuned during and beyond Wave 2.
    

Testnet faucet will be rate-limited (0.01 SUI per request) in order to provide fair access to gas tokens and to ensure a smooth experience

*   The API-based faucet will be disabled for Testnet Wave 2 to discourage bot-based abuse — only a Discord-based faucet will be available.
    

Between epoch changes, Frenemies, the Validator Game, and a variety of ways to test the v1 tokenomics implementation, we’re excited for a dynamic, action-packed, and informative Wave 2!

Thank you for participating in Testnet and being part of the journey towards Sui Mainnet!
