比特币对接
地址分类
- p2sk(``)
- p2skh(主网地址是以"1"开头,例如:
16dN3XhaTejyZFy4hWompK2x8de2T46wA8; 测试网是以"m"或"n"开头, 例如:mvZjn2485hwxjVPJoLAZVyJKUDn8aGpBy5) - p2sh (主网地址是以"3"开头,例如:
33ZzFZZJcvtnLBWRdne6F9SpD9Rc7sjSDX; 测试网以"2"开头,例如:2Mt5wo9k8ykrJLrszhom1drPLNSArYAbLsH; ), 目前, 多重签名基本上使用这种类型地址
提币流程
1.地址导入
-
热钱包(私钥在钱包软件中):通过钱包密码就可以直接进行转账
-
观察钱包(私钥不在钱包软件中):只能监测地址的入币和出币,可以通过listunspent列出其utxo集, 也可以使用createrawtransaction创建交易
2.列出utxo
通过rpc接口listunspent列出一个地址的utxo集
listunspent 最小确认数 最大确认数 ["地址1", "地址2" ] include_unsafe(是否包含不安全的utxo,即确认数太少) query_options("其他查询选项")例如:listunspent 0 9999999 '[\'2MyeRq1tEWJR9rNeTcAZzoW6tUZiQpvRJum\']' true 
3.创建裸交易
createrawtransaction "[{\"txid\":\"1f945d93db219da806538eacb9251856687c40b5879941ddd01692734c8c229d\", \"vout\":1}]" "{\"mv4rnyY3Su5gjcDNzbMLKBQkBicCtHUtFB\":\"0.0001\",\"2Mt5wo9k8ykrJLrszhom1drPLNSArYAbLsH\":\"0.028000\"}"
4.交易签名(离线, 在线)
- 离线签名(支持多签, 如果是p2sh地址, 需要填写redeemScript, redeemScript创建多签地址时生成的, 如果是普通p2sh地址需要将私钥导入钱包,使用listunspent可以查看到redeemScript)

在线签名(私钥在钱包中)不需要inputs
-
普通p2skh地址(主网是"1"开头, 测试网是"m"或"n"开头), input中不需要填写 redeemScript
5.发送交易
在全节点上使用sendrawtransaction发送即可
如果在signerawtransaction时,input中的amout填写错误, 在发送sendrawtransaction会出现non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation) (code 64) (code -26)

区块监测(充币通知)
-
方案1(理论上适用所有币)
解析最新区块中的交易, 找到关心的交易
根据区块hash获取区块信息
-
方案2(比特币可以用这种方法做, 其他币未知)
将地址导入钱包中(观察钱包), 使用
listunspent(可以设置确认数)来监测区块变化, 例如:使用listunspent 0 0 ["地址A"]可以查看交易池中刚刚收到的交易, 通过设置确认数可以查看地址是否入币了
