QuillAudits Periodic On-Chain Analysis of your web3 Project
Miscellaneous
Hi there! Welcome onboard with QuillAudits. We are glad you chose us; let's buckle up and begin.
QuillAudits is a leading name in Web3 security, offering top-notch solutions to safeguard projects across DeFi, GameFi, NFT gaming, and all blockchain layers. With Seven years of expertise, we've secured over 1400+ projects globally, averting over $30 billion in losses. Our specialists rigorously audit smart contracts and ensure DApp safety on major platforms like Ethereum, BSC, Arbitrum, Algorand, Tron, Polygon, Polkadot, Fantom, NEAR, Solana, and others, guaranteeing your project's security with cutting-edge practices.
In blockchain technology, layer 1 protocol refers to the underlying infrastructure or foundational layer that provides the basic functionality of the blockchain. It is often described as the base layer of the blockchain architecture, as it includes the core components such as the consensus mechanism, the block structure, and the transaction format.
Overall, layer 1 protocols form the foundation of the blockchain ecosystem and play a crucial role in enabling the secure and decentralized transfer of value and information across the network.
<aside> β οΈ Ethereum Classic has suffered a 4,000-block-long reorganization, its second incident in five days. The first attack, which saw more than 3,000 blocks reported, had an attacker steal over 800,000 ETC, worth about $5.6 million.
The Bitcoin Gold (BTG) network suffered another 51% attacks on January 23-24, as roughly 29 blocks were removed in two deep blockchain reorganizations (reorgs). Reports indicate that over 7,000 BTG was double spent ($70,000) in two days.
According to various reports, Verge's cryptocurrency network suffered a 51% attack, leading to a massive 560,000+ block reorganization. Analysts believe the Verge network attack could be history's deepest blockchain reorganization (reorg), with roughly 200 daysβ worth of verge transactions wiped.

L1 (Layer 1) blockchain protocols, also known as base protocols, are the fundamental layer of a blockchain network. They provide the underlying framework for the blockchain's operation, including its consensus mechanism, data storage, and network communication.
<aside> π§ A security audit is necessary for L1 blockchain protocols for several reasons:
Overall, a security audit is an important step in ensuring the security and reliability of a blockchain protocol, especially at the L1 level. It can help identify and fix vulnerabilities, increase trust and confidence in the network, and protect the reputation of the protocol and its developers.
</aside>
<aside> β 1. 51% attack: A 51% attack could be used to gain control over the network by controlling the majority of the network's computing power.
Double-spending attack: A double-spending attack could be used to spend the same cryptocurrency twice by manipulating the network's consensus mechanism.
Sybil attack: A Sybil attack could be used to create a large number of fake nodes in the network to manipulate the consensus mechanism
Eclipse attack: An Eclipse attack could be used to isolate a node or group of nodes from the rest of the network to manipulate the consensus mechanism.
Forking attack: A forking attack could be used to split the network into two or more chains, causing confusion and potentially allowing for double-spending or other attacks.
6.Denial-of-service attack: A denial-of-service attack could be used to overwhelm the network with traffic, preventing legitimate transactions from being processed.
Timejacking attack: A timejacking attack could be used to manipulate the network's time synchronization mechanism, potentially allowing for double-spending or other attacks.
Consensus algorithm attacks: Attacks could be targeted towards specific consensus algorithms used by the network, such as Proof-of-Work or Proof-of-Stake, in order to manipulate the network's consensus mechanism.

Define the scope of the audit, including the components to be audited, the risks to be assessed, and the objectives of the audit.
Identifying the potential attack surface of the blockchain protocol, including the components that attackers, such as the consensus mechanism, smart contracts, and cryptographic algorithms, could target.
We Review the codebase of the blockchain protocol, looking for potential vulnerabilities or flaws that could be exploited by attackers. We use a combination of manual code review and automated tools to identify potential vulnerabilities, such as buffer overflows, unhandled exceptions, and other common coding errors.
We Assess the security and reliability of the consensus mechanism used by the blockchain protocol, looking for potential attack vectors, such as Sybil attacks, 51% attacks, or double-spending attacks.
Evaluating the cryptographic algorithms used by the blockchain protocol, looking for potential weaknesses or vulnerabilities that could be exploited by attackers
Assess the authentication and authorization mechanisms used by the blockchain protocol, looking for potential vulnerabilities or flaws that could allow unauthorized access to the network.
Reviewing the network security measures used by the blockchain protocol, looking for potential vulnerabilities or weaknesses that could be exploited by attackers, such as DDoS attacks or man-in-the-middle attacks.
Evaluate the performance and scalability of the blockchain protocol, looking for potential bottlenecks or scalability issues that could impact the performance of the network.
Based on the results of the audit, We will Document All Findings in a Report with recommendations for improving the security and efficiency of the blockchain protocol, including best practices for code development, security measures, and risk mitigation strategies. This may include:
<aside> π¦ How can you help? You have to prepare an 'Updation Summary' or 'Comment Report' carrying details of the changes you've made after getting the IAR; this would help us identify the changes and test them rigorously.
</aside>
Follow up with the blockchain protocol team to ensure the recommended changes are implemented and provide ongoing support and guidance as needed.
After Follow Up and Receiving initial audit fixes from Project Team, We Will Review the Fixes and Complete Code again, and the Final Audit Report will be delivered. Even after your fixes, some issues are still unresolved, and/or those changes have led to a few more issues.
So, after receiving the Final Audit report, you have to take a call (based on the severity table containing the unresolved issues) on whether to alter the code again or to move forward as it is.
After getting the green light from the previous step, we send the report to our designers to generate a PDF version of the Audit Report, displaying all the necessary details of the auditing process.
Sample Audit Report
Then, the report is uploaded to our official GitHub Repository., after which we share the link to the Audit Report and Certificate of Compliance from QuillAudits.
After the Final Audit report, we take your project in front of the masses through :
