具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
图1为本发明一实施例提供的一种扫码发红包方法的流程图。
如图1所示，在本实施例中，本发明提供一种扫码发红包方法，包括：
S12：响应于发红包，生成包括第一私钥和第一公钥的第一公私钥对，根据第一公钥生成发红包交易并发送至区块链节点以供通过第一合约执行，将红包款项冻结在第一合约中，并将第一公钥记录在第一合约中；
S14：通过第一私钥签名生成凭证信息，根据凭证信息生成红包二维码并通过预配置的方式展示，以供第二用户端通过采集红包二维码获取凭证信息，根据凭证信息和第一地址生成领红包交易并发送至区块链节点以供通过第一合约执行，解冻部分或全部的红包款项并转账至第一地址。
其中，执行领红包交易包括：验证第一地址是否已领取该红包：已领取则执行失败；以及，根据第一公钥验证凭证信息：验证失败则执行失败。
以下以面对面扫码发红包为例，对上述方法进行示例性阐述。
用户甲在需要进行面对面发红包时，在用户端(例如手机或平板等设备)中输入红包金额及数量、选择付款账户、进行身份验证等。
在步骤S12中，用户甲的用户端响应于上述用户甲的操作，生成包括第一私钥p和第一公钥P的第一公私钥对，生成将红包款项转账至合约账户，并且包括第一公钥P的发红包交易tx1，将tx1发送至区块链节点。
区块链节点接收、广播、打包tx1后，通过第一合约执行tx1，将红包款项转账至合约账户并冻结，并将第一公钥P记录在合约中。
在步骤S14中，用户甲的用户端根据第一私钥p签名生成凭证信息m(对任意内容签名均可)，根据凭证信息m生成红包二维码并展示在用户端的屏幕上。
用户乙、丙、丁的用户端分别扫描用户甲的用户端的屏幕以采集该红包二维码，对采集到的红包二维码解码以获取到凭证信息m。
以用户乙的用户端为例，获取凭证信息m后，根据m和用户乙的 地址addr 乙生成领红包交易tx2并发送至区块链节点。其中，tx2中应包括第一合约的合约地址，该合约地址可以由用户端预配置，也可以由用户甲的用户端通过红包二维码传递。
区块链节点接收、广播、打包tx2后，通过第一合约执行tx2，验证addr 乙是否已领取该红包：是，则tx2执行失败；以及，根据第一公钥P验证凭证信息m的签名：验证失败，则tx2执行失败；若tx2执行成功，则根据预配置的红包分配规则解冻部分或全部的红包款项并转账至addr 乙。
其中，预配置的红包分配规则可以配置为均分或随机分配，等等。例如，一种随机分配方式具体配置为：
判断剩余未领取的红包个数是否大于1：
否，则解冻全部剩余红包款项并转账至第一地址；
是，则根据剩余红包款项的第一数额生成小于第一数额的第二数额；以及，获取区块链生成的第一随机数，并取第二数额与第一随机数的余数，得到第三数额；解冻第三数额的红包款项并转账至第一地址。其中，第一随机数可以根据CN201811351787.0号申请所公开的随机数生成方法所生成，也可以根据本领域的其它随机数生成方法所生成。
用户丙和用户丁的用户端以同样的方式进行红包领取，不再一一赘述。
以上以面对面发红包的场景为例进行了示例性的阐述，上述方法还适用于在即时通讯工具中进行1对1发红包或群发红包等不同场景，区别仅在于步骤S14中将生成的红包二维码作为图片信息在即时通讯工具中进行发送，而第二用户端通过识别图中二维码的方式获取凭证信息。
在一优选实施例中，发红包交易还包括第二地址，第一合约还用于监测红包款项是否在预配置的时长内发放完：否，则解冻未发放的剩余款项并转账至第二地址。
同样以用户甲发红包为例，在本实施例中，发红包交易tx1还包括第二地址addr 甲，预配置的时长为24小时，当第一合约在24小时 后检测到该红包还存在未发放的剩余款项，则解冻剩余款项并转账至addr 甲。
其中，预配置的时长可以以时间单位作为时长单位，也可以以区块高度作为时长单位；预配置的时长可以由第一合约指定，也可以由用户甲通过发红包交易tx1指定，可实现相同的技术效果。
上述各实施例通过将公钥存储到区块链上的合约中，并通过私钥签名生成通过红包二维码传递的凭证信息，使领取到红包的用户端根据凭证信息生成领红包交易，由合约根据存储的公钥验证凭证信息，以及验证同一地址是否重复领取红包，并在验证通过后发放红包，实现了安全易用的去中心化的红包发放。
在一优选实施例中，根据第一私钥签名生成的各凭证信息各不相同；
上述执行领红包交易还包括：验证凭证信息是否已领取红包：已领取则执行失败。
具体地，同样以用户甲发红包为例，为了避免某一用户的用户端获取凭证信息m后，通过多个地址(例如addr 乙-1、addr 乙-2、addr 乙-3…等)重复领取红包，可以由用户甲的用户端为每一位红包领取方分别生成各不相同的领取凭证(只需根据第一私钥对任意的不同内容进行签名即可)，并由合约在执行领红包交易tx2时验证tx2中的凭证信息m是否已领取过红包：是，则tx2执行失败。
需要说明的是，该优选方法仅适用于逐一向发红包对象展示不同的红包二维码的发红包场景，而不适用于在即时通讯工具中群发红包。
上述实施例进一步通过由发红包的用户端为每一份红包生成不同的凭证信息，并由合约验证同一凭证信息是否重复领取红包，进一步提升了安全性。
图2为本发明一实施例提供的另一种扫码发红包方法的流程图。图2所示的方法可配合图1所示的方法执行。
如图2所示，在本实施例中，本发明还提供另一种适用于用户端的扫码发红包方法，包括：
S22：通过采集红包二维码获取凭证信息；其中，红包二维码由第 一用户端通过第一私钥签名生成凭证信息，根据凭证信息生成并通过预配置的方式展示，第一私钥及对应的第一公钥由第一用户端响应于发红包所生成，并根据第一公钥生成发红包交易并发送至区块链节点以供通过第一合约执行，将红包款项冻结在第一合约中，将第一公钥记录在第一合约中；
S24：根据凭证信息和第一地址生成领红包交易并发送至区块链节点以供通过第一合约执行，解冻部分或全部的红包款项并转账至第一地址。
其中，执行领红包交易包括：验证第一地址是否已领取该红包：已领取则执行失败；以及，根据第一公钥验证凭证信息：验证失败则执行失败。
优选地，根据第一私钥签名生成的各凭证信息各不相同；执行领红包交易还包括：验证凭证信息是否已领取红包：已领取则执行失败。

S34：通过第一合约执行领红包交易，解冻部分或全部的红包款项并转账至第一地址；其中，领红包交易由第二用户端通过采集红包二维码获取凭证信息，根据凭证信息和第一地址生成，红包二维码由第一用户端通过第一私钥签名生成凭证信息，根据凭证信息生成并通过预配置的方式展示。
其中，执行领红包交易包括：验证第一地址是否已领取该红包：已领取则执行失败；以及，根据第一公钥验证凭证信息：验证失败则执行失败。
优选地，根据第一私钥签名生成的各凭证信息各不相同；执行领红包交易还包括：验证凭证信息是否已领取红包：已领取则执行失败。
优选地，发红包交易还包括第二地址，第一合约还用于监测红包款项是否在预配置的时长内发放完：否，则解冻未发放的剩余款项并转账至第二地址。

否，则解冻全部剩余红包款项并转账至第一地址；
是，则根据剩余红包款项的第一数额生成小于第一数额的第二数额；以及，获取区块链生成的第一随机数，并取第二数额与第一随机数的余数，得到第三数额；解冻第三数额的红包款项并转账至第一地址。
