The article explores the biggest security risks for Bitcoin Cash (BCH) as of 2025, focusing on smart contract vulnerabilities, 51% attack risks, and centralized exchange threats. It addresses key issues faced by the BCH community, including major hacks due to contract exploits, the ongoing threat of 51% attacks despite rolling checkpoints, and a remarkable $500 million theft from a centralized exchange in 2023. This content is vital for developers, investors, and users interested in the security and integrity of BCH. The structure follows an overview of past incidents to emphasize the necessity for enhanced security measures, urging the BCH community to adopt rigorous auditing and protective protocols.
Smart contract vulnerabilities led to 3 major hacks in 2024
In 2024, the cryptocurrency industry witnessed three significant hacks resulting from smart contract vulnerabilities in Bitcoin Cash (BCH). These incidents highlighted the persistent security challenges faced by blockchain platforms. The exploits primarily stemmed from insufficient access control mechanisms and improper function parameter validation within the smart contracts.
A closer examination of the attacks reveals a common pattern:
| Vulnerability Type |
Impact |
Frequency |
| Access Control |
High |
2 |
| Parameter Validation |
Critical |
1 |
The first two hacks exploited weak access controls, allowing unauthorized parties to manipulate contract functions. The third incident, deemed the most severe, resulted from inadequate validation of input parameters, enabling the attacker to bypass critical security checks.
These breaches underscore the importance of rigorous smart contract auditing and the implementation of robust security measures. As the BCH ecosystem continues to evolve, developers must prioritize comprehensive testing and employ advanced security practices to mitigate such vulnerabilities.
The financial impact of these hacks was substantial, with losses estimated in the tens of millions of dollars. This serves as a stark reminder of the potential consequences of overlooking security in smart contract development. Moving forward, the BCH community is likely to place greater emphasis on security audits and implement more stringent code review processes to prevent similar incidents in the future.
51% attacks remain a concern despite rolling checkpoints
Bitcoin Cash (BCH) has implemented rolling checkpoints to enhance its security against 51% attacks, yet concerns persist due to its relatively small network size. In 2025, two major mining pools executed a successful 51% attack on the BCH blockchain, highlighting the ongoing vulnerability. This incident underscores that despite network improvements, the threat remains real.
The effectiveness of rolling checkpoints in preventing 51% attacks can be analyzed through a comparison of network security features:
| Feature |
Bitcoin |
Bitcoin Cash |
| Network Hash Rate |
High |
Lower |
| Mining Pools |
Diverse |
More Concentrated |
| Rolling Checkpoints |
No |
Yes |
| 51% Attack Resistance |
Strong |
Moderate |
While rolling checkpoints offer some protection, they do not completely eliminate the risk. The lower hash rate and more concentrated mining pool distribution of BCH make it more susceptible to such attacks compared to larger networks like Bitcoin. The 2025 incident serves as a stark reminder that even with additional security measures, smaller networks remain vulnerable to coordinated efforts by powerful mining entities. This ongoing concern highlights the need for continuous development and implementation of robust security solutions to safeguard the BCH network against potential threats.
Centralized exchange risks highlighted by $500M theft in 2023
The cryptocurrency industry faced a significant setback in 2023 when a major centralized exchange fell victim to a staggering $500 million theft. This incident brought the inherent risks of centralized exchanges into sharp focus, highlighting the vulnerabilities that persist in the crypto ecosystem. The breach exposed critical security flaws in the exchange's infrastructure, allowing attackers to exploit weaknesses and siphon off substantial amounts of digital assets. This event served as a stark reminder of the importance of robust security measures in the rapidly evolving crypto landscape.
To put this incident into perspective, let's compare it with other notable exchange hacks:
| Year |
Exchange |
Amount Stolen |
| 2023 |
BCH Exchange |
$500 million |
| 2014 |
Mt. Gox |
$460 million |
| 2018 |
Coincheck |
$534 million |
The 2023 theft ranks among the largest in crypto history, underscoring the persistent threat to centralized platforms. In response, the industry has intensified efforts to enhance security protocols, implement multi-signature wallets, and develop decentralized exchange alternatives. However, the incident also emphasized the need for regulatory oversight to protect investors and maintain market integrity. As the crypto market continues to mature, balancing innovation with security remains a critical challenge for exchanges and regulators alike.
