区块链地址是什么？如何获取地址信息 | Tokenview

本文主要是介绍区块链地址是什么？如何获取地址信息 | Tokenview，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

区块链地址一般指的是钱包地址。区块链上的钱包说白了就是管理数字资产（我们通常说的币）的工具，你币的转入转出以及转入转出的记录，都是通过钱包来实现的。就像你回家要有家庭住址一样，数字货币也要有个回家的地址。不同的是，数字货币的地址是唯一的。你有了地址，别人才能给你转账。

地址是什么?在一个区块链系统中，私钥一般是由专门的随机算法随机生成的256位2进制字符串，公钥是由私钥通过不可逆的算法生成的，（即你你只能通过初始值推算出结果，但是无法通过结果推算出初始值），公钥又通过不可逆算法的出地址（注：有些区块链系统中地址就是公钥，公钥到地址再做一次运算是为了让系统更安全。）这里不得不提的是，因为是通过的不可逆算法进行运算，只能由私钥推出公钥，由公钥推出地址，反之，你知道别人的地址或者公钥，你完全推不出别人的私钥。

如何获得区块链的地址信息呢。如果自己搭建或者是团队搭建，费时费力。其实还可以借鉴第三方节点服务，直接调用接口就可以获取地址信息，用于搭建区块链钱包。

• 非智能合约公链：通过公链简称和地址可获取地址信息包括：余额，排名，交易次数，转出数量，收入数量，以及最近一笔交易详情，示例：

•         {"code": 1,"msg": "成功","data": [{"type": "address","network": "BTC","hash": "183hmJGRuTEi2YDCWy5iozY8rZtFwVgahM","rank": 6,"txCount": 32,"spend": 0,"receive": 85947.34749882,"txs": [{"type": "tx","network": "BTC","height": 548509,"index": "802","time": 1541201463,"txid": "af77d09561400f32cc2036ca43b5c40a90405d1905a51f59bc3bf4ff94674d5f","fee": "0.00000226","inputs": [{"input_no": 0,"address": "1AK4LYE6PYwBmSYHQX3v2UsXXHTvCAsJeK","value": "0.00073409"}],"outputs": [{"output_no": 0,"address": "1AK4LYE6PYwBmSYHQX3v2UsXXHTvCAsJeK","value": "0.00072628"},{"output_no": 1,"address": "183hmJGRuTEi2YDCWy5iozY8rZtFwVgahM","value": "0.00000555"}]}]}]
  }
  
  

• 智能合约公链：通过公链简称和代币地址，获得代币的信息包括：该代币被交易的交易笔数，持有该代币的人数（余额>0），以及该代币的发行量，全称，简称，精度，图标信息。示例：

•         
  {"code": 1,"msg": "成功","data": {"network": "ETH","tokenHash": "0x519475b31653e46d20cd09f9fdcf3b12bdacb4f5","transferCnt": 1007327,"holderCnt": 2839,"tokenInfo": {"h": "0x519475b31653e46d20cd09f9fdcf3b12bdacb4f5","p": "ETH","f": "VIU","s": "VIU","d": "18","t": "1000000000"}}
  }
  
  

• 地址余额：通过公链简称和地址，获得地址余额。示例：

•         
  {"code": 1,"msg": "成功","data": "0.019239809829239"
  }
  
  

• 智能合约地址:通过公链简称和地址，获得地址信息包括：余额，排名，交易次数，转出数量，收入数量，以及最近一笔交易详情，示例

•         {"code": 1,"msg": "成功","data": {"type": "address","network": "ETH","hash": "0x77777777777c868ba9b9772b1da1128d820a3cc0","addrAlias": null,"rank": 3429146,"txCount": null,"spend": null,"receive": null,"txs": [{"type": "tx","network": "ETH","height": 4669357,"blockHash": "0xecff7b1c859a913068604c231fb7a6e2498c6d51050d008555457a074ac7a9b5","index": "54","time": 1512319744,"txid": "0x6369b23c7e1648026559952dff6e2e1e6c5b15040e279aa69e76750a9e461907","fee": "0.000021","confirmations": null,"nonce": 4359091,"formIsContract": null,"toIsContract": null,"block_no": 4669357,"gasPrice": 1000000000,"from": "0xea674fdde714fd979de3edf0f56aa9716b898ec8","gasLimit": 50000,"value": "0.04958108415768947","to": "0x77777777777c868ba9b9772b1da1128d820a3cc0","gasUsed": 21000,"callTransferErr": null,"tokenTransferErr": null,"traceErr": null,"receiptErr": null,"create": null,"suicide": null,"callTransfer": null,"tokenTransfer": null},
  

• 代币持有者地址信息：通过代币平台简称和地址，获得地址信息包括：余额，排名，交易次数，以及最近50笔交易详情。示例：

•         
  {"code": 1,"msg": "成功","data": {"type": "address","network": "ETH","hash": "0x18a744e4564601a5241c910aa0cd69aee82287a8","rank": 834906,"txs": [{"type": "tx","network": "ETH","height": 6636957,"blockHash": "0x26cb320d14a0e4845dab192eed1b8e740268e6d6fab720e2433b4e65cd794941","index": "105","time": 1541264645,"txid": "0xb7ade7d9c0bd088679e76056f4024d3c9494609f005309c0b9dfafa209139a47","fee": "0.00036624","nonce": 60,"toIsContract": 1,"block_no": 6636957,"gasPrice": 10000000000,"from": "0x18a744e4564601a5241c910aa0cd69aee82287a8","gasLimit": 54168,"value": "0","to": "0xe36df5bb57e80629cfc28a31e5f794071c085eca","gasUsed": 36624},
