安全无小事
如果有一个项目上线,需要出一个100倍的险怎么办?这个问题像之前的Cover的赔付问题或者是Compound在去年3.12的时候大跌,导致清算的状况或者Harvest整个被盗都牵扯到非常巨大的资金量。

不管是各种类型的保险项目可能都会面临着你可能需要有一个很大资金量的赔付问题,如果遇到这样的问题,该怎么来处置,有人保了一个很高额的保险或者这个项目被清算了?

安全无小事,更大的资金体量往往吸引着更多黑客的目光。主持人之前提到的Cover、Nexus Mutual、以及之前Compound的清算、Harvest资金被盗等等都涉及到巨大的资金量,可能决定一个项目的生死。首先用户需要意识到需要为DeFi项目中的资金投保,其次是保险是否能对这种大额资金做出赔付。

这一点Soteria独特的资本模型决定了其可以比较好的适应这种大额赔付情况。Soteria保险资金池由所有合约共享,资金规模远大于各个合约独立的资金池,但如何保障不因某一个项目的赔付导致整个平台不可用是需要平台仔细设计的。Soteria使用了由欧洲保险和职业养老金管理局开发的Solvency II方法得出的精算数学来设置其最低资本要求。

Soteria的精算模型不仅对大额赔付友好,同时方便小型项目快速启动,无需担心参与人数过少无法启动。Soteria预备了14%的代币作为DeFi合作伙伴启动的资金,可以快速做出风险担保从而推进B端,进而极大的降低了普通用户的参与门槛。

Soteria它的整个资本模型用澳洲保险还有他们的职业养老金,感觉很像是国内的五险一金,给你养老用的,他们会有一个精算的数学系统,经由这个系统精算过后然后来决定这个保险金的赔付状况。

整个Soteria保险池也是所有合约共享,资金规模远大于每一个独立合约。也想听听Helmet这边Orange的看法,刚刚听到不管是腰斩的赔付或者是卖飞的赔付这些保险可能也会面临一些大额赔付的状况,能不能请Orange说明一下。

好的,Helmet做的并不是单纯保险提供商而是保险平台,它其实是P2P的逻辑。在承保方和投保人进行保险发布和交易的时候都会明确提示大家的风险,而且今天刚刚增加一些新的功能。

Helmet的保单系统建立在独立运营的智能合约上,并不依赖Oracle和Admin。另外关于大额赔付的问题,保单是名义价值为背书的,在通过系统要抵押一定的保证金,从而规避投保方的资金风险,保单的持有人其实可以随时购买基础代币。他们P2P的保单的交易其实在完全的Helmet合约智能保险保障下。

团队初期做了激励性质和提供流动性的活动性的保单,比如上线第二天就发售了价值8万美金的Helmet的0.12美金的cover保险,每张面值是0.12美金,在5分钟就抢购一空,如果Helmet跌破这个价格,用户可以持有这个保单而来找进行赔付,那么关于这种大额赔付的问题,只有八个字可以说,负责到底,全额赔付。

负责到底,全额赔付,这八个字会让去Helmet保一大堆的保险。今天真的会认真研究每一场保险项目。也想问一下在场的三位,你们觉得DeFi的哪些赛道是特别值得关注的,不只是保险这个领域,DeFi会讲到其它的,就是借贷领域,最近一直在说DeFi结合NFT资产,还有DeFi未来发展趋势,个人当然首先会关注去中心化保险。当然还会比较关注钱包以及预言机,特别是后者。

相信大家对钱包可能会更熟悉,这里主要解释下为什么会更关注后者预言机以及预言机是什么。

大家都知道,大所要上一个新DeFi项目,必然要经过审计。但是智能合约的审计是静态的,也就是说,审计仅仅可以在DeFi智能合约上线之前有效地发现漏洞并找出相应解决方案。

但是,咱们暂且先不说代码在开发测试过程中的更新,可能会使已完成的安全审计失效。哪怕审计后的代码无懈可击,并且上线之前没有任何改动,智能合约一旦上线到了真实的生产环境中,一些未授权的软件程序和还没被审核的合约也会产生交互。
