測(cè)試網(wǎng)絡(luò)被設(shè)計(jì)來替代 Bitcoin block chain,，用于測(cè)試,。它允許程序開發(fā)者或 bitcoin 試用者進(jìn)行試驗(yàn)性的操作,，而不用擔(dān)心破費(fèi) bitcoin 或破解 bitcoin chain.

運(yùn)行 bitcoin 或 bitcoind 時(shí)添加參數(shù) -testnet 即可,，或者在 bitcoin.conf 中添加一行 testnet=1 亦可,。

兩者區(qū)別

• 使用18333端口替代8333,。
• Bootstrapping IRC channel is #bitcoinTEST instead of #bitcoin (both on irc.lfnet.org). The built-in node list is disabled.
• A different value of ADDRESSVERSION field ensures no testnet BitCoin addresses will work on the production network. (0x6F rather than 0x00)
• The protocol message header bytes are shifted up (0xFABFB5DA instead of 0xF9BEB4D9)
• Minimum difficulty of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty.
• A new genesis block
