A developer-focused testnet blockchain, Block Chain uses BITCOIN as its native currency (Chain ID 6231991) for low-cost, low-risk transaction and integration testing.
Block Chain is a Bitcoin testnet network (UTXO-based, with SegWit/Taproot) used to safely develop and simulate BTC transfers for cross-chain bridging without real economic risk. Typical performance for comparison: ~10-minute target block time, a few TPS in bursts, and near‑zero fees on testnet (≈0–1 sat/vB), with generally low/irregular activity. Primary use cases include end‑to‑end bridge testing, wallet/integration QA, and fee/confirmation‑time tuning that mirrors Bitcoin mainnet behavior.
Block Chain is unique because its native currency is BITCOIN and it uses Bitcoin’s fee model (sats per vByte) instead of EVM “gas,” so testing doesn’t require a separate gas token and results closely match Bitcoin mainnet dynamics. Compared with typical EVM/L2 networks (multi‑second blocks and higher TPS), it follows Bitcoin’s ~10‑minute blocks, few‑TPS throughput, and ≈0–1 sat/vB testnet fees—ideal for high‑fidelity UTXO and cross‑chain bridge testing using faucet BTC and widely supported Bitcoin tooling.
Block Chain uses BITCOIN as the gas token for transaction fees. You can obtain BITCOIN by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge BITCOIN to Block Chain, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select Block Chain as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on Block Chain you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add Block Chain to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send BITCOIN on Block Chain, ensure your wallet is connected to the Block Chain network, enter the recipient's address, specify the amount of BITCOIN to send, review the gas fee, and confirm the transaction in your wallet.
