Testnet Faucets

• http://test.faucet.masternode.io - by coingun
• http://faucet.test.dash.crowdnode.io - by ndrezza
• https://test.faucet.dashninja.pl - by elbereth

Arguments and commands

• Reference: https://docs.dash.org/en/stable/wallets/dashcore/cmd-rpc.html
• 在 bin 資料夾裡面會有 dashd, dash-qt, dash-cli, dash-tx 四個執行檔
• dashd: Dash Core Daemon
• dash-qt: Dash Core QT GUI
• dash-cli: Dash Core RPC client
• dash-tx: Dash Core dash-tx utility

基本操作

$ ./dashd --daemon //Run in the background as a daemon and accept commands
$ ./dash-cli <command> //Send command to Dash Core

Testnet

• Reference: https://docs.dash.org/en/stable/developers/testnet.html
• 在 command 後，加上 –testnet
• Ex:
  ​​​​$ ./dashd --testnet
  ​​​​$ ./dash-cli --testnet
  

Options

option	Description
–txindex	Maintain a full transaction index, used by the getrawtransaction rpc call (default: 1)
–addressindex	Maintain a full address index, used to query for the balance, txids and unspent outputs for addresses (default: 0)
–timestampindex	Maintain a timestamp index for block hashes, used to query blocks hashes by a range of timestamps (default: 0)
–spentindex	Maintain a full spent index, used to query the spending txid and input index for an outpoint (default: 0)

如果已經下好帳本，要新增 index 功能，要加上 –reindex

Example

$ ./dashd --testnet --daemon --addressindex
$ ./dash-cli --testnet <command>

查詢區塊高度

$ ./dash-cli (--testnet) getblockcount
( Returns the number of blocks in the longest blockchain. )

• return:

142935

創建地址

$ ./dash-cli (--testnet) getnewaddress
( Returns a new Dash address for receiving payments. )

• return (addr):

yfJ971rJSFQt2SfGWVJZdyX8Rdiv7jsjeg

查詢餘額

1. 查特定地址餘額 (要開 addressindex 功能)

$ ./dash-cli (--testnet) getaddressbalance '{"addresses": ["address"]}'
( Returns the balance for an address(es) (requires addressindex to be enabled ).

• return:

{
  "balance": 8887859774,
  "received": 8887859774
}

2. 查錢包餘額

$ ./dash-cli (--testnet) getbalance
( returns the server’s total available balance )

• return:

88.87859774

3. 查錢包裡地址餘額

$ ./dash-cli (--testnet) listaddressbalances
( Lists addresses of this wallet and their balances )

• return:

{
  "yN8saAJ5tzaVaahHHRHF4YHbwHvX3Dv7ix": 0.00000000,
  "yS6KfQfz4ygedPsjTZWbCRJiRj1R66TozY": 88.87859774
}

Transaction

• Transaction Example: https://dash-docs.github.io/en/developer-examples#transactions

Simple Spanding

$ ./dash-cli (--testnet) sendtoaddress "address" amount
( Send an amount to a given address. )

• return (txid):

bbffc3......

Complex Raw Transaction

1. 取得可用 txid

$ ./dash-cli (--testnet) listunspent
( Returns array of unspent transaction outputs )

• return:

[
  {
    "txid": "bbffc3......",
    "vout": 1,
    "address": "yS6KfQfz4ygedPsjTZWbCRJiRj1R66TozY",
    "amount": 88.87859774,
    ...
  },
  ...
]

2. 取得 key

$ ./dash-cli (--testnet) dumpprivkey "myaddress"
( Reveals the private key corresponding to 『address』. )

• return (key):

cN93x2......

3. create 交易

$ ./dash-cli (--testnet) createrawtransaction "[{\"txid\":\"mytxid\",\"vout\":n}, ...]" "{\"address\":amount, ...}"
( Create a transaction spending the given inputs and creating new outputs. )

• return (hex):

0200000001ea9......

mytxid, n, address, amount 都要填
input 照著步驟1.得到的結果填
假設這筆 txid 有10塊錢，要給對方5塊錢，交易費為0.001，則 address 有兩筆，一筆填對方地址，amount 填5塊，另一筆填自己地址，amount 填4.999塊

4. sign 交易

$ ./dash-cli (--testnet) signrawtransaction "hexstring" [] [\"privatekey\", ...]
( Sign inputs for raw transaction (serialized, hex-encoded). )

• result (signedhex):

{
  "hex": "0200000001ea9......",
  "complete": true
}

5. send 交易

$ ./dash-cli (--testnet) sendrawtransaction "signedhex"
( Submits raw transaction (serialized, hex-encoded) to local node and network. )

• result (txid):

383045......

查詢交易結果

1. 查看鍊上交易資訊

$ ./dash-cli (--testnet) gettransaction “txid“
( Get detailed information about in-wallet transaction <txid> )

• return:

{
  "blockhash": "000000003adb2741881f8e9dc64d767b9b10318faa6cc54f52931574439223eb",
  ...
}

2. 利用 hash 值得到區塊

$ ./dash-cli (--testnet) getblock “blockhash”
( returns a string that is serialized, hex-encoded data for block 『hash』. )

• return (block):

{
  "height": 142932,
  ...
}

3. 利用 getblockcount 得到區塊高度

$ ./dash-cli (--testnet) getblockcount
