作者：Flowie，链捕手 Acala 遭黑客攻击增发超 12 亿稳定币 AUSD、Solana生态钱包大面积被盗……不夸张地说，区块链2022年这大半年一半热点都是安全问题贡献的。 根据Certik发布的安全报告，仅在 2022 年前 6 个月，区块链与Web3 项目就因黑客攻击和漏洞利用而损失超 20 亿美元，并已经超过 2021 全年的总和。 安全问题爆发的同时，很多项目方的智能合约要安排上安全审计，却可能要排队到半年之后。即使审计完成了，也如大家所看的那样，依然会面临被攻击的风险。 区块链安全毫无疑问是刚需，但一个现实是，无论是项目方还是普通用户，似乎都很难有安全感。 在这样的背景下，我们观察到新入场的安全服务厂商们前赴后继。截止到目前，2022年陆续有Carret、BlockSec、Secure3、Halborn、Redefine等海内外安全公司获得了较大金额的融资，其中Certik几乎近一年内筹集了4轮资金，市场之火热可见一斑。 在本文中，我们试图从安全“守护者”的现状去看，整个区块链安全究竟面临着怎样的困境？行业格局又在发生怎样的演变？ 还在“拓荒”的区块链安全服务区块链“野蛮”生长，安全的需求同时激增，但安全服务却跟不上。 BlockSec联合创始人周亚金提到，“智能合约的安全审计排队2-3月是近两年的常态，很多项目的安全审计服务甚至都排队到了半年之后。”而从成都链安的数据来看，2022年第二季度，被攻击的项目中，接近一般的项目未能经过安全审计。 尽管安全服务商们前赴后继，但在YM Capital |
