DeFiCon is a nonprofit conference with a mission to elevate the ethos of peer-to-peer crypto.

DeFi, crypto, and NFT communities consist of more than only profit maximalists, degens, gamblers, and ponzi apes – they are full of daring and creative innovators. Our 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 ecosystem thrives on accessibility, participation, building, creativity, and even a little weirdness. Peer-to-peer crypto has and will become the evolution of human organization and the future of France, open to anyone and everyone who wants to contribute.

As a nonprofit conference, the focus shifts from maximizing profit to maximizing the experience for the attendees. We will donate all proceeds above the event’s cost to charity while unifying the crypto community under one house. The goal is to ensure the value is found at our event and to inspire both new participants and people already familiar with DeFi.
Join DeFiCon’s 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 ecosystem event to hear from top protocols, investors, activists, creatives, builders, and more in August.

First Annual DeFi Security Summit

DeFi is an emerging suite of applications for decentralized asset management over blockchain technology. DeFi is becoming a major economic vehicle in modern society. The Ethereum blockchain alone already manages more than 235 billion USD worth of assets. One of the basic principles behind DeFis is that the code is law and computer programs called smart contracts that run on the blockchain dictate the conditions and the effects for asset transactions. This groundbreaking idea has many desirable benefits that originate from trust-minimizing and immutable aspects of decentralized public blockchains. However, vulnerabilities in smart contracts and in their applications may be exploited to steal or deny access to assets managed by them. Mitigation and prevention of such damages are challenging and require new software development and security design methodologies. Hundreds of millions in USD value have already been lost due 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 to vulnerabilities in smart contracts. Therefore, smart contract security is a significant concern for DeFi applications.

Criminals have made off with 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 over $10 billion in 'DeFi' scams and thefts this year


LONDON — Investors have lost billions of dollars to criminals targeting so-called "decentralized finance" platforms this year.

According to a report from London-based firm Elliptic, more than $10 billion worth of user funds has been stolen in cases of fraud and theft on DeFi products, which aim to replicate traditional financial services using blockchain technology.

DeFi has often been referred to as the "Wild West" of cryptocurrencies. Such services often promise users huge returns but lack any involvement from middlemen like banks. High-interest rate savings and lending products are a common sight in the space.

But, as is to be expected with a young industry like crypto, DeFi platforms aren't regulated. It's something regulators have tried to come to grips with recently amid a spate of major hacks and scams.

Overall losses caused by DeFi exploits has totaled $12 billion so far in 2021, according to Elliptic, a firm which tracks movements of funds on the digital ledgers that underpin cryptocurrencies.

Fraud and theft accounted for $10.5 billion of that sum — a sevenfold increase from 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 last year.

"The DeFi ecosystem is an incredibly exciting and fast-moving space, with financial services innovation happening at light speed," said Tom Robinson, chief scientist at Elliptic.

"This is attracting large amounts of capital to projects that are not always robust or well-tested. Criminal actors have seen the opportunity to exploit this."

Over the last two years, the total amount of money deposited at DeFi services has spiked from just $500 million to $247 billion.

It comes as the price of

But as the market has grown in size, so has the level of illicit activity. Earlier this year, DeFi platform Poly Network lost more than $600 million in what was, at the time, the biggest cryptocurrency theft of all time.

In a bizarre turn of events, the entirety of the funds was later restored by the hackers, which claimed they exploited Poly Network to highlight flaws in its system.

There have also been a number of so-called "rug pulls," where scammers convince investors to buy their token and then take off with the funds after raising a certain amount.


Regulators are growing concerned about the rapid rise of DeFi.

The Securities and Exchange Commission is seeking information from Uniswap Labs, the start-up behind a decentralized crypto exchange of the same name, on how investors use the platform and the way in which it is marketed.

A Uniswap Labs spokesperson said the firm was committed to complying with the law and assisting regulators with their inquiries.避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法

The problem, experts say, is that DeFi services often market themselves as decentralized, when that isn't always the case.

The Financial Action Task Force, a global anti-money laundering watchdog, recently released revised guidance on cryptocurrencies calling on countries to identify individuals with "control or sufficient influencer" over DeFi programs.

DappRadar数据还显示,2020年以太坊新增 DeFi DApp 达106个,占当年总新增的44.54%;以太坊以外 DeFi DApp 新增132个,占总新增的55.46%。

不过,DeFi爆发之下,似乎很像一个纷乱的战国时代。这些 DeFi 项目里锁着数百亿美元的虚拟货币资产,对于黑客而言,无疑是令其趋之若鹜的一块肥肉。

据《派盾2020年年度数字货币反洗钱报告》显示,DeFi攻击事件达到60起,损失逾2.5亿美元。其中,有⾄少10起为闪电贷攻击,包括bZx、Balancer、Harvest、Akropolis、CheeseBank、ValueDeFi和OriginProtocol等多个DeFi项目遭到攻击,至少5起为重入攻击,包括Uniswap、Lendf.Me、Sushiswap、Akropolis、OriginProtocol。其中,2020年10月 DeFi 攻击损失达到 3380 万美元,为全年 DeFi 攻击造成损失最多的一个月;11月, DeFi 攻击达到 10起,为全年攻击频率最高的一个月。

2020年 DeFi 安全事件及损失统计

由此可见,当下DeFi项目如履薄冰。鉴于目前DeFi安全形势,派盾建议,一方面,在上线之前要进行全面而专业的智能合约安全审计,排查已知的各类漏洞;另一方面,要注意排查与其他 DeFi 产品进行组合时的业务逻辑漏洞,避免出现跨合约的逻辑兼容性漏洞。


币安方面,2020年9月币安智能链(BSC)正式上线,随后宣布提供 1 亿美元的资金支持开发者,截至2021年1月12日,当前有100多个项目使用币安智能链,包括流动性挖矿 Swap、钱包、NFT、预言机、去中心化身份、支付等。

火币方面,2020 年 12 月 21 日火币生态链Heco正式上线,还成立了Heco生态专项基金,重点扶持火币生态平台上的DEX、借贷、预言机、跨链解决方案、保险等优质项目。

分析人士认为,以太坊作为智能合约平台的领先地位当前很难撼动,而由于以太坊 Gas 费不断上涨,DeFi 避免因去中心化金融(DeFi)诈骗而损失资金的六种不同方法 向外延伸已成必然。同时,以太坊2.0为其带来了新的突破点与无限的想象空间。

“DeFi已经形成了丰富的行业生态,并将在未来对旧有的金融格局产生影响。”OKEx CEO Jay Hao发微博称,DeFi作为新生事物仍存在许多问题,如底层公链性能瓶颈导致的清算风险,项目同质化出现的逆向选择,合约漏洞造成的资产损失等。
