Why do decentralized projects need testnets for scaling solutions?

Testnets help test scaling solutions like sharding or Layer 2 protocols. They allow developers to simulate high transaction volumes, ensuring scalability improvements function efficiently before being applied to the mainnet.

Testnets are crucial for ensuring that scaling solutions work effectively before going live on the mainnet. It's like a dress rehearsal for blockchain projects, helping developers identify and fix any potential issues with high transaction volumes.

Testnets play a vital role in stress-testing blockchain projects and ensuring smooth performance on the mainnet. Identifying and fixing issues beforehand is key to a successful launch.
