安裝omnicore程序

請前往https://github.com/OmniLayer/omnicore/tags查看最新版本並替換下面的下載鏈接

jian@ubuntu:/root# wget https://github.com/OmniLayer/omnicore/releases/download/v0.3.1/omnicore-0.3.1-x86_64-linux-gnu.tar.gz
jian@ubuntu:/root# tar -zvxf omnicore-0.3.1-x86_64-linux-gnu.tar.gz 
jian@ubuntu:/root# sudo install -m 0755 -o root -g root -t /usr/local/bin ./omnicore-0.3.1/bin/*

配置bitcoin參數

jian@ubuntu:~$ mkdir .bitcoin	#創建主目錄,如果目錄已經存在請跳過
jian@ubuntu:~$ mkdir omnidata	#創建區塊數據目錄
jian@ubuntu:~$ cd .bitcoin/
jian@ubuntu:~/.bitcoin$ vi bitcoin.conf

將下面信息全部複製，並修改rpcuser（RPC用戶名），rpcpassword（RPC用戶密碼），rpcallowip（允許訪問的ip地址）然後保存

# Generated by https://jlopp.github.io/bitcoin-core-config-generator/

# This config should be placed in following path:
# ~/.bitcoin/bitcoin.conf

# [rpc]
# Accept command line and JSON-RPC commands.
server=1
txindex=1
# Username for JSON-RPC connections
rpcuser=omnicorerpc

# Password for JSON-RPC connections
rpcpassword=omnicorerpc

# Listen for JSON-RPC connections on this port
rpcport=17443
# 爲了不與比特幣端口衝突，使用的不是默認端口所以要加上下面的設置
listen=0

# Allow JSON-RPC connections from specified source. Valid for <ip> are a single IP (e.g. 1.2.3.4), 
# a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). This option 
# can be specified multiple times.
rpcallowip=192.168.1.178

# 設定默認爲私有鏈
regtest=1

# 區塊數據目錄
datadir=/root/omnidata

啓動omnicore程序

請將-conf和-datadir 路徑修改爲你的路徑

jian@ubuntu:~/.omni$ omnicored -conf=/root/.omnicore/bitcoin.conf -daemon

出現上面的信息然後按Ctrl + C退出即可，初始化1分鐘後再查看是否啓動成功，要不然不會輸出任何信息，需要輸入上一步配置的密碼，用戶名omnirpc改爲你bitcoin.conf中配置的用戶名：

jian@ubuntu:~$ curl --user omnicorerpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnetworkinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18332

能返回下面的信息表示啓動成功

{"result":{"version":130200,"subversion":"/Satoshi:0.13.2/","protocolversion":70015,"localservices":"000000000000000d","localrelay":true,"timeoffset":0,"connections":2,"networks":[{"name":"ipv4","limited":false,"reachable":true,"proxy":"","proxy_randomize_credentials":false},{"name":"ipv6","limited":false,"reachable":true,"proxy":"","proxy_randomize_credentials":false},{"name":"onion","limited":true,"reachable":false,"proxy":"","proxy_randomize_credentials":false}],"relayfee":0.00001000,"localaddresses":[],"warnings":""},"error":null,"id":"curltest"}

停止omnicore程序

jian@ubuntu:~/.omni$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf stop

創建錢包地址

jian@ubuntu:~$ curl --user omnirpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnewaddress", "params": ["test"] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/

{"result":"n1Axxy3WGwFci1GJffwdY55dRem92GKXAm","error":null,"id":"curltest"}

返回結果中的 “n1Axxy3WGwFci1GJffwdY55dRem92GKXAm” 即爲新創建的USDT錢包，以m開頭表示是測試鏈的錢包地址，公鏈上的錢包地址一般是1開頭

查詢餘額

查詢比特幣餘額

jian@ubuntu:~$ curl --user omnicorerpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getbalance", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/

查詢USDT餘額，請將錢包地址換成你的

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf omni_getbalance "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm" 1

或者

jian@ubuntu:~$ curl --user omnicorerpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "omni_getbalance", "params": ["n1Axxy3WGwFci1GJffwdY55dRem92GKXAm", 1] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/

獲取測試幣

在測試網絡testnet和私有網絡regtest下獲取測試幣的方式是一樣的，私有鏈使用生成區塊命令獲得比特幣後用下面的命令往moneyqMan7uh8FqdCA2BV5yZ8qVrc9ikLP發送比特幣可以得到一點測試的USDT，每1BTC可以獲得100個USDT。爲了方便讓測試幣進入我們指定的錢包地址，我們另外生成一個指定賬號的錢包地址

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf getnewaddress "omni"
n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd

執行得到錢包地址n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd,然後往這個錢包地址轉入比特幣

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf sendtoaddress "n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd" 10

生成一個區塊讓幣到賬

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf generate 1

用下面的命令查看omni賬戶的餘額可以看到餘額已經在該賬戶所屬的n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd地址中

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf listreceivedbyaddress 1 true

[
 {
    "address": "n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd",
    "account": "omni",
    "amount": 10.00000000,
    "confirmations": 1,
    "label": "omni",
    "txids": [
      "c9da93e8a0daad57b7b4702b3ceac3d4dd51cbb563c7e982712c573eaab95715"
    ]
  }
]

然後用omni賬戶往moneyqMan7uh8FqdCA2BV5yZ8qVrc9ikLP地址轉一個比特幣

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf sendfrom "omni" "moneyqMan7uh8FqdCA2BV5yZ8qVrc9ikLP" 1

再次生成一個區塊讓幣到賬

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf generate 1

查看餘額，可以看到100個USDT已經到賬

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf "omni_getbalance" "n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd" 1
{
  "balance": "100.00000000",
  "reserved": "0.00000000",
  "frozen": "0.00000000"
}

注意：如果你的區塊高度沒有到達100個以上，你將得不到任何比特幣和USDT

使用下面的命令可以查看所有餘額大於0的幣種和餘額

jian@ubuntu:~$ omnicore-cli -conf=/root/.omnicore/bitcoin.conf omni_getwalletaddressbalances

[
  {
    "address": "n2zPfoSavpGGxZwJf3pya3mXX5HVEG6wmd",
    "balances": [
      {
        "propertyid": 1,
        "name": "Omni",
        "balance": "100.00000000",
        "reserved": "0.00000000",
        "frozen": "0.00000000"
      }, 
      {
        "propertyid": 2,
        "name": "Test Omni",
        "balance": "99.00000000",
        "reserved": "0.00000000",
        "frozen": "0.00000000"
      }
    ]
  }
]

可以看到在私有網絡下發送比特幣會給你返回兩種測試幣，propertyid分別是1和2，但是在主鏈，USDT的propertyid分別是31

發送交易

參數分別是from，to，代幣id，交易數量，支付btc手續費的地址

jian@ubuntu:~$ omnicore-cli "omni_funded_send" "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm" "n4VTWrjPV1QaLmM1x8ZtyLiJoFk3KaCAsi" 1 "1" "n1Axxy3WGwFci1GJffwdY55dRem92GKXAm"

如果出現報錯Error with selected inputs for the send transaction，說明比特幣或者USDT餘額不足，往錢包轉入足夠的幣即可。

訪問JSON-RPC

可以查看：https://github.com/OmniLayer/omnicore/blob/master/src/omnicore/doc/rpc-api.md，需要用編程語言對接的話可以使用api中的函數和參數拼裝成json數據，例如本文中的查詢餘額的 json 爲{"jsonrpc": "1.0", "id":"curltest", "method": "getbalance", "params": [] }，然後將這串json作爲參數post提交到節點的ip和端口即可返回相應的json結果。
