How Did Dogecoin and Zcash Tackle Source Code Vulnerabilities That Exposed $25B in Crypto?

Crypto network vulnerabilities remain at large in 2023 after a disastrous 2022. In the latest example, a security research team revealed massive risks at Dogecoin, Litecoin, and Zcash, with developers warning of additional risks.

Cryptocurrencies use an open-source codebase designed to allow anyone to inspect, modify, and distribute the software’s source code. This openness promotes transparency, accountability, and innovation, enabling the crypto community to continually develop and improve blockchain technology.

However, it also means that the code is vulnerable to exploitation by malicious actors who can identify and exploit its weaknesses.

Different Ways Bad Actors Can Penetrate Network

Here are some ways in which open-source codebase can have vulnerabilities that could affect the security of the blockchain.

Coding errors: Even the most experienced developers can make coding errors that could leave the code open to exploitation. For instance, a developer might create a vulnerability by failing to perform proper input validation, making it possible for an attacker to inject malicious code into the system. Similarly, an error in memory allocation or data handling could cause data corruption or leaks.
Lack of code review: Open-source codebases rely on peer reviews to identify and fix issues in the code. However, if the codebase lacks a rigorous review process, it can lead to security gaps that attackers can exploit. Additionally, inexperienced developers who make changes without fully understanding the implications of their modifications can introduce new vulnerabilities.
Forked code: Forking is a process in which developers change an existing codebase to create a new project. Although forking is expected in the open-source community, it can introduce vulnerabilities if the developers fail to incorporate security updates or make improper changes. If a forked project becomes popular, attackers may target it due to its potential vulnerabilities.
Software dependencies: Many open-source projects function correctly using third-party libraries and frameworks. While these dependencies can save time and effort, they can also introduce vulnerabilities if they contain flaws or
