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\"}"

外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传

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

外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传

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
