# Bitcoin mainnet, testnet, signet and regtest Bitcoin mainnet carries the normal BTC ledger. Testnet and signet are separate testing networks; regtest is intended for controlled local development. Their coins, chain histories and some consensus or block-production rules differ. Test-network familiarity helps rehearse a workflow, but it does not prove identical mainnet fees, timing or safety. Always verify the selected chain and use dedicated test credentials.

BIP-94 defines Testnet 4 changes rather than renaming mainnet. Signet adds a challenge that valid blocks must satisfy, supporting more coordinated testing. Regtest lets a developer control block creation in a local scenario. That makes it useful for repeatable tests but a poor simulation of adversarial public hash-power competition. Evidence: [Testnet 4](https://raw.githubusercontent.com/bitcoin/bips/927b6de9915c9262615a6399de51b200f81e5aa4/bip-0094.mediawiki); [Signet](https://raw.githubusercontent.com/bitcoin/bips/927b6de9915c9262615a6399de51b200f81e5aa4/bip-0325.mediawiki) ## A successful rehearsal is scoped evidence Imagine sending 10,000 test satoshis between two test wallets and confirming the result. This checks that particular wallet workflow on that selected chain. It does not transfer 10,000 mainnet satoshis or establish the mainnet cost of repeating the action. Before testing, inspect the chain field or the application’s network indication. Similar-looking addresses or familiar interface colors are not sufficient network identification.

Core’s data layout separates chain-specific state, but a human can still select the wrong application or destination. Test tokens are for testing, not a substitute for BTC. Faucet availability, unusual testnet market behavior or a temporary testing shortage does not change which chain a transaction belongs to.

The ledgers are separate. A testnet transaction does not create a mainnet UTXO or convert test coins into BTC. Use the correct chain’s destination and wallet when rehearsing a payment.

No. BIP-325 requires an additional block challenge solution alongside proof of work. That coordination is useful for testing but is a distinct network assumption. Evidence: [Signet](https://raw.githubusercontent.com/bitcoin/bips/927b6de9915c9262615a6399de51b200f81e5aa4/bip-0325.mediawiki) ## Claims and scope ### bitcoin-test-networks-quick-answer Bitcoin mainnet carries the normal BTC ledger.
