3 - 3 收款

有了地址可以收錢了～

我們可以去 https://testnet.manu.backend.hamburg/faucet 申請測試網路的比特幣

申請後我們可以先看看自己的餘額

$ bitcoin-cli getbalance
0.00000000

看到是 0 不要緊張，因為比特幣是每十分鐘才有一個區塊，

而交易至少要寫到一個區塊上才能被認定是成功的(更安全是要等6個區塊)

每十分鐘產生一個區塊的動作稱之為「挖礦」，是由礦工們付出電力進行 「POW計算」所挖得

bitcoin-cli getwalletinfo 可以得到錢包資訊

$ bitcoin-cli getwalletinfo

bitcoin-cli listtransactions 可以得到所有的交易

$ bitcoin-cli listtransactions

這一筆交易 c71ec531a2149dba59bca99c4646de919d213c516156d39f03cef2459eb1cb35 寫著 mrR54buSCnMnf9cBGSrg4zCrWdDnyiQkdM 這個地址收("receive")了 1.3 個比特幣

有另一個指令是 bitcoin-cli listunspent 這個指令是列出沒用到的 UTXOs (什麼是 UTXO)

如果想看交易的細節，可以用 bitcoin-cli getrawtransaction

$ bitcoin-cli getrawtransaction "c71ec531a2149dba59bca99c4646de919d213c516156d39f03cef2459eb1cb35"

看不懂吧？我們在指令後面加個 1

就可以看到這筆交易是從哪些 UTXO 來的

可以看到我的比特幣是從 2NDYhZ2XhTcGnf8NoCraSZd8LWsn61ZWWnk 這個地址送過來的
