Testnet

Penjelasan
Sobat Kripto, testnet adalah replica blockchain untuk testing. Developer test smart contract dan dApp di testnet sebelum deploy ke mainnet (real network). Token di testnet tidak punya real value. User bisa dapat testnet token via faucet (free distribution). Critical untuk development cycle: catch bug sebelum mainnet deployment cost real money.
