The Stacks 2.0 Testnet is a global testing environment, providing opportunities for stress testing the system and functionality that will mirror the Stacks 2.0 Mainnet.
Overall goals for this testnet are as follows:
Quality: Testnets are a “staging” environment for the eventual mainnet and can help surface critical bugs, missing features, and rough edges. We need your help in running and experimenting with the testnet code, so we can have a high-quality mainnet launch.
Community: Testnets can serve to activate interest in the network, resulting in community growth and broader exposure among developers .
