#DeFi安全事件 Looking back on the past, I can't help but feel a surge of emotions. The recent large-scale attack on Balancer and its fork protocol reminds me of the ups and downs in the DeFi space over the past few years. From the $560,000 flash loan attack in 2020 to the current over $100 million loss, Balancer's journey to security has been quite difficult.

Every event serves as a wake-up call for us. From the front-end hijacking and code vulnerabilities in 2023 to this year's major security incidents affecting multiple chains, they all highlight the fragility of the DeFi world. Especially for projects like Balancer, which are highly regarded and frequently forked, their security issues can have widespread implications.

Counting the attack methods over the years: Flash Loans, cross-protocol vulnerabilities, front-end hijacking... The attackers' methods are constantly evolving, and we always seem to be one step behind. Every major incident feels like it sets the industry's development clock back by half a year or even a year. This raises the question: Are we too eager to pursue innovation while neglecting the most basic security measures?

History is always strikingly similar. Looking back at past cases, it is not difficult to find that many problems are actually preventable. However, during a fervent bull market, we often overlook those small yet deadly hidden dangers. Perhaps now is the time for us to calm down and reassess the entire Decentralized Finance ecosystem security architecture.

After all, security is always the lifeline of this industry. Only by strengthening the security defenses can we truly promote the large-scale application of Decentralized Finance. Otherwise, no matter how many innovations there are, they are just castles in the air. Let us learn from history, work together, and safeguard the future of DeFi.
