Audit of Ethereum 2.0 client Teku, blockchain insurance, Open DeFi, virtual events, and more media coverage... here’s what happened at Quantstamp in October.

Quantstamp Completes Audit of 2nd ETH 2.0 Implementation

We’re excited to announce the completion of our audit of Teku, the Ethereum 2.0 client developed by ConsenSys. This marks Quantstamp’s 2nd audit of an Ethereum 2.0 implementation: the Prysm client by Prysmatic Labs was audited by Quantstamp in July. 

“Ethereum 2.0 is on track to deliver Phase 0 in the very near future,” says Quantstamp CEO Richard Ma. “Client teams have spent countless hours coordinating, testing, and working with auditing firms to ensure that the foundation of Ethereum 2.0 is ready for delivery.” 

The audit included enforcing network consensus rules, maintaining consensus, and code that controls rewards and penalties for stakers. Overall, it was a very collaborative process. The code base was high quality, and any findings were disclosed as they were discovered, allowing the Teku development team to quickly resolve them. 

Formally Verifying Hedera Hashgraph's Stablecoin Framework

Stablecoins provide a compelling opportunity for enterprises by combining the transparency, security, and privacy of a digital asset with the stability of traditional currency. However, since 2017, over a quarter billion USD worth of digital assets have been lost or stolen due to errors in smart contract development. For enterprises to be comfortable leveraging the benefits of stablecoins, rigorous software verification and extensive auditing is crucial. Quantstamp has developed a formal specification for stablecoins built on Hedera Hashgraph and deployed using the Hedera Consensus Service.

The framework shortens development time, provides formal guarantees about the correctness of functions, removes the need to develop new tests, and creates a shared understanding amongst developers in regards to the stablecoins’ architecture and functionality. Developers seeking to integrate Hedera Hashgraph stablecoins into their platforms have certain security guarantees that reduce complexity and create a more predictable environment.

When stablecoins follow a secure framework, it facilitates their integration into other financial applications and helps support the development of a healthy stablecoin ecosystem. This also makes it easier for enterprises to create safe and compliant stablecoins.

Other Recent Audits

Aavegotchi: Quantstamp has now completed our audit of Aavegotchi's ghst-staking repository. Aavegotchi allows users to collect, compete, and combine Aavegotchis for a gamified experience that brings the concept of DeFi staking to NFT collectibles. GHST is the native utility token used as the medium of exchange between participants in the Aavegotchi ecosystem.

DerivaDEX: DerivaDEX is a decentralized exchange for derivative contracts built on top of Ethereum, powered by a DAO and decentralized insurance fund. As a community-owned exchange, their token allows users to participate in the governance and operations of the exchange. This is also the first major project to implement an upgradeability framework called Diamond. "Diamonds" are contracts that get external functions from other contracts, called "facets". Additional facets can then get added, removed and modified down the road via governance.

Nodle: Nodle is an IoT platform building on Polkadot using Substrate. Substrate is a blockchain framework that gives projects the ability to deploy an autonomous IoT network that directly connects to other blockchains. Nodle is attempting to solve two major challenges that face the IoT space: connectivity and security. With a more scalable payments chain, Nodle can power its global rewards network while remaining decentralized and secure.

Powertrade: Powertrade is a Bitcoin options trading platform with a mobile-first approach. 

Quantstamp Joins Open DeFi

This month, Quantstamp was one of five more members to join the global DeFi initiative Open DeFi, along with Aave, DyDx, Balancer, Outlier Ventures, and BlockScience. This global alliance unites blockchain leaders and DeFi startups to foster cross-border market growth, sustainability, and innovation.

Having secured over $5 billion USD of value for over 140 blockchain projects, Quantstamp has unique insights into risk management and is excited to share our unique knowledge with the Open DeFi community. Participating in the risk management track, we look forward to learning from our peers and working together to address some of the industry's biggest challenges. This recent CoinTelegraph article provides some additional information about the initiative and some of its other members.

The Status of Insurance in the Blockchain Industry

Traditionally, the concept of insurance is very familiar—there is always the chance that an unlikely event takes place that leads to expensive one-time costs. 

In the blockchain space, well over a quarter billion dollars worth of cryptocurrency has been lost or stolen due to bugs in smart contracts since 2017. While audits are still essential, they do not completely eliminate the possibility of a bug being present in code. 

Enter blockchain insurance. Blockchain insurance is still in its early days and has focused more on exchanges such as Coinbase or Crypto.com. More recently, on-chain insurance was popularized by Nexus Mutual. But as the blockchain ecosystem matures, the security needs of the space are evolving. 

Quantstamp’s extensive experience in the blockchain space has made us uniquely qualified to assess risk in this industry. In this recent post, we cover the three types of services Quantstamp offers to help our clients protect themselves against smart contract security risk.


Liquidity2020 Summit took place on October 16 - 18, hosted by Dystopia Labs. Quantstamp CEO Richard Ma presented  “The Future is Still DeFi”. Attendees got to hear about some of the hacks that took place this year, exciting projects we’re working on, and what’s next for the DeFi space. If you missed it, you can watch Richard’s talk on YouTube or find the other sessions online.

LA Blockchain Summit

LA Blockchain Summit kicked off October 6-7th, hosting 200+ international industry leaders discussing the future of blockchain technology, decentralized finance, digital securities, and more. 

Quantstamp CEO Richard Ma presented on a panel entitled Strong Privacy and Regulatory Compliance: Reasons We Can’t Pitch DeFi to Enterprises Yet. If you missed the live event, watch the session on YouTube.

Media: Quantstamp’s Recent Teku Audit

Quantstamp was featured in both Decrypt and CryptoBriefing in regards to the recent completion of our Teku audit. 

The migration of Ether and the DeFi ecosystem to Ethereum 2.0 is a high stakes process, with over 28 billion USD worth of Ether and other digital assets depending on the successful transition to proof-of-stake. Quantstamp is thrilled to have worked with the Teku team and look forward to the future of Ethereum.

Quantstamp 公告

对Ethereum 2.0客户端Teku的审计、区块链保险、Open DeFi、虚拟活动等媒体报道......以下是10月份发生在Quantstamp 。

Quantstamp 完成对第二次ETH 2.0实施情况的审计。

我们很高兴地宣布,我们对ConsenSys开发的Ethereum 2.0客户端Teku的审计已经完成。这标志着Quantstamp对Ethereum 2.0实现的第2次审核:Prysmatic Labs的Prysm客户端已于7月由Quantstamp 审核。 

"Ethereum 2.0正按计划在不久的将来交付0阶段,"Quantstamp CEO Richard Ma说。"客户团队已经花费了无数时间进行协调、测试,并与审计公司合作,以确保Ethereum 2.0的基础已经准备好交付。" 


正式验证Hedera Hashgraph的稳定币框架。

稳定币将数字资产的透明度、安全性和隐私性与传统货币的稳定性相结合,为企业提供了一个引人注目的机会。然而,自2017年以来,由于智能合约开发的错误,已经有价值超过25亿美元的数字资产丢失或被盗。要想让企业放心地利用稳定币的优势,严格的软件验证和广泛的审计是至关重要的。Quantstamp ,开发了一个建立在Hedera Hashgraph上的稳定币正式规范,并使用Hedera共识服务进行部署。

该框架缩短了开发时间,提供了关于函数正确性的形式化保证,消除了开发新测试的需要,并在开发者之间建立了关于稳定币架构和功能的共同理解。寻求将Hedera Hashgraph稳定币整合到其平台中的开发人员有一定的安全保证,降低了复杂性,创造了一个更可预测的环境。




Aavegotchi: Quantstamp ,目前我们已经完成了对Aavegotchi的ghstake存储库的审核。Aavegotchi允许用户收集、竞争和组合Aavegotchis,以获得游戏化体验,将DeFi押注的概念引入NFT收藏品。GHST是原生的实用代币,用作Aavegotchi生态系统中参与者之间的交换媒介。


NodleN odle是一个使用Substrate在Polkadot上构建的物联网平台。Substrate是一个区块链框架,它使项目能够部署一个自主的物联网网络,直接连接到其他区块链。Nodle试图解决物联网领域面临的两大挑战:连接和安全。通过更可扩展的支付链,Nodle可以为其全球奖励网络提供动力,同时保持去中心化和安全。

Quantstamp 加入Open DeFi

本月,Quantstamp 与Aave、DyDx、Balancer、Outlier Ventures和BlockScience一起,成为又五个加入全球DeFi倡议Open DeFi的成员之一。这个全球联盟联合了区块链领导者和DeFi初创公司,以促进跨境市场的增长、可持续性和创新。

,为140多个区块链项目担保了超过50亿美元的价值,Quantstamp ,对风险管理有独特的见解,很高兴能与Open DeFi社区分享我们独特的知识。参与风险管理轨道,我们期待着向同行学习,并共同解决行业的一些最大挑战。最近的这篇CoinTelegraph文章提供了一些关于该倡议及其其他一些成员的额外信息。




进入区块链保险。区块链保险仍处于早期阶段,更多的是集中在Coinbase或Crypto.com等交易所。最近,链上保险由Nexus Mutual普及。但随着区块链生态系统的成熟,该领域的安全需求也在不断发展。 

Quantstamp'在区块链领域的丰富经验使我们在评估这个行业的风险方面具有独特的资格。在最近的这篇文章中,我们介绍了Quantstamp 提供的三类服务,以帮助客户防范智能合约安全风险。


Liquidity2020峰会于10月16日-18日举行,由Dystopia Labs主办。Quantstamp CEO Richard Ma发表了"未来还是DeFi"的演讲。与会者听到了今年发生的一些黑客事件,我们正在进行的令人兴奋的项目,以及DeFi领域的下一步计划。如果你错过了,你可以在YouTube上观看Richard的演讲,或者在网上找到其他会议
