今天,通往Harmony的第一层区块链的Horizon Bridge遭到骇客攻击,估计已经被窃取了价值一亿美元的加密货币,包括Frax (Frax),、Wrapped Ether (WETH)、Aave (Aave)、Sushi (Sushi)、Frax Share (FXS)、AAG (AAG)、币安USD (BUSD)。Dai (Dai)、Tether (USDT)、Wrapped BTC (WBTC)和USD Coin (USDC)等,而不幸的是,骇客已经开始将赃款兑换成并以太币(ETH)。目前,Harmony团队正在与国家机关和专家合作,企图找寻相关解决方案。

Harmony(来源:Crypto News)

Harmony? Horizon Bridge? Harmony由Stephen Tse在2018年创立,是一个具有独特功能的的区块链平台,旨在引入状态分片来解决区块链的扩容问题,在显著提升网络性能的同时不损失安全性和去中心化发展。

Harmony具有提高区块本身的可拓展性的深度分片系统(Deep Sharding)、共识协议、分布式随机生成和跨链的互操作性,能够减少以太坊的局限性。Harmony的原生代币为ONE,取名来自于平台愿景——“For One and For All”。

Horizon Bridge是Harmony官方开发的跨链桥,利用智能合约锁定用户的原始资产,在Harmony上铸造新的资产分发给用户,可以任意实现以太坊ERC-20种类的代币(如Tether (USDT), Chainlink (LINK), AAX Token (AAB)等)、币安智能链BEP-20代币,甚至是将比特币跨链到Harmony上。这些 “桥” 存在的意义,等同于现实生活中的海关。

举个例子,若小美今天在以太坊的主网上有ETH,但是想要在Harmony的链上使用,由于这两个区块链是独立的,有着不同的协议、规则、社区和机制,因此便需要通过区块链的“海关”(即“桥”)来进行资产转移,将资产转移至Harmony上。按照实现方式,“桥”可以分为信任桥无需信任桥,前者由一个中心机构保管用户资金(如Ethereum Bridge和Horizon Bridge),后者则是基于智能合约和算法的去中心化桥,不要求用户信任某个机构才能使用,资金总是由用户保管。

而在这一次的骇客攻击事件中,无需信任桥和其资产都没有受到波及,目前,Horizon Bridge在各大平台上都暂时运营。虽然Harmony官方尚未说明事件发生的主因,但是在此之前,加密币风险基金Ape Dev的创始人Chainstride Capital指出,Horizon Bridge所需的签名者数量很少容易遭到骇客攻击,许多人也预测这是Horizon Bridge遭到攻击的主因。
