欧易区块链60讲 | 第57集:什么是区块链+司法取证?

哈喽大家好,我是小K君,今天我们要讲的内容是:“什么是区块链+司法取证”?

司法取证是区块链已经落地的应用场景之一。可能有不少小伙伴会比较疑惑,区块链和司法取证能有什么关系?两者完全八竿子打不着啊。但区块链技术却可以解决司法流程中证据真实性的问题。

我们都知道,证据收集是司法审判中的重要一环,而证据的有效性主要从三个要素进行评估,真实性、关联性、合法性。其中真实性又是重中之重,可问题来了,在黑科技泛滥的今天,如何才能证明证据的真实性呢?

比如照片,可以通过p图软件进行修改,录音也可以通过调音的方式进行伪造。这就造成,在法院诉讼的过程中,千辛万苦获取到的证据,可能因为律师的一句质疑,而不了了之。所以,证明证据有效性的最大难点,就是需要事先证明证据是没有被篡改过的。

而不可篡改不正是区块链的特点之一嘛?区块链的本质是一个分布式的去中心化数据库,一旦数据上链,就会被链上的各个节点进行备份,想要对这个数据进行修改,就必须攻破全网50%以上的节点,这就决定数据是极难篡改的,刚好解决了证据的不可篡改性的问题。

但这还不能彻底说明证据是有效的,因为区块链技术虽然可以确保证据在存储的过程中不可篡改,却无法对存证数据本身的真实性作出担保。

于是,各区政府干脆上线了区块链技术的取证APP,大家可以在里面实现录音、录像、拍照等取证行为,证据会通过平台直接生成,并传递到区块链上进行备份,上传后,这个文件会通过区块链的加密算法进行加密,任何人可以拿着这份文件到区块链平台进行校验,来确认这份文件是否被篡改过。进而使任何人都不能在取证过程中造假,从源头解决了证据是否真实的问题。

目前,我国最高人民法院在关于互联网法院的规定中,将区块链识别为证据收集、固定和防篡改技术手段,确立了区块链存证运用的合法性,此外北京、深圳、杭州等地区,均上线了相关的区块链取证平台,为广大的执法人员提升了固证效率,相信随着区块链技术在司法领域的应用,可以带来一个更加公平、公正的新互联网世界。
