Security Challenges In Blockchain For dApp Development

The competition to establish Web3 has commenced – including advanced dApp development. An array of stakeholders, including venture capitalists, cryptocurrency startups, engineers, and visionaries, are actively involved in developing WEB3 powered by blockchain. This emerging frontier offers a more democratic, decentralized, and independent platform, making it ideal for data recovery.

However, despite the promise of decentralization and enhanced security, there are several instances of man-in-the-middle attacks that highlight the imperfections in current infrastructures.

To tackle these security issues, let’s revisit the concept of WEB3. The primary goal of WEB3 is to address the security challenges caused by centralization and provide individuals with control over their data and identification. To determine the extent of security breaches in your blockchain infrastructure when it comes to dApp development, it is crucial to assess the current state of technology.

Security Challenges In dApp Development

When examining the internal aspects of WEB3, technologies such as EVM, Solidity, and JavaScript continue to play a significant role. However, the discussion about backend features involves the use of Node providers and WEB3 API providers.

Node providers are companies that offer their services as an alternative to setting up and running your own nodes. This approach proves convenient as it eliminates the stress and expense associated with node setup. By transmitting your dApp transaction requests via the internet to the node provider, you can leverage their services. For smart contract development, utilizing one or two node providers for redundancy is common practice.

WEB3 API providers, on the other hand, collaborate with nodes behind the scenes. These providers offer tools that allow users to access pre-compiled and pre-computed data on the blockchain. Moreover, these WEB3 APIs facilitate seamless communication and interaction between different applications. Employing reliable APIs ensures consistent and stable coding, making them indispensable for application development.

💡 Difference between Node providers and WEB3 API providers: 
A WEB3 provider enables your application to communicate with a blockchain node by submitting JSON-RPC requests to a server. Node service providers operate distributed node clients in the background, facilitating blockchain read and write operations using an API key.

Understanding the Security Threats Faced by dApp Developers

While nodes are relatively primitive technologies, they remain valuable. For instance, a WEB3 node cannot provide information about users’ account deposits. Nodes also have limitations in processing multiple smart contracts and can only handle a single chain. Fortunately, APIs offer a solution to overcome these limitations.

APIs define and standardize application interactions, enabling access to raw blockchain data. This is why WEB3 APIs play a crucial role in dApp development. By providing a straightforward interface, WEB3 APIs facilitate software integration with other applications. Since reliable APIs promote consistent coding within a stable environment, dApp developers can avoid reinventing the wheel.

Furthermore, using these WEB3 provider APIs allows easy connectivity to nodes without the hassle of establishing direct connections. These APIs also grant access to valuable precalculated and precompiled on-chain data. However, these services do not fully address the security concerns of developers, and in many cases, require upfront payment.

Unfortunately, the number of dApps being compromised through man-in-the-middle attacks is on the rise. Attackers exploit vulnerabilities in DNS servers to redirect jsonrpc-endpoints traffic, resulting in unauthorized access. Several instances of such attacks have been reported, leading to significant losses for victims, including approximately 16.5 WBTC (equivalent to ~$350,840). Approximately 23 cryptocurrency projects have fallen victim to similar DNS attacks.

Mitigating Security Risks for dApps

Fortunately, a straightforward solution exists to protect against man-in-the-middle attacks in dApp development. However, to implement this solution, a highly skilled and cohesive development team is required.

Building your own solution may seem appealing, but it’s crucial to recognize the challenges involved. The seemingly simple task can quickly become complex, requiring years of experience to navigate successfully. Therefore, if you have ample time and resources at your disposal, pursuing this path can be considered.

Identifying Violations of Blockchain Principles in WEB3 Infrastructure

Let’s take a moment to examine the current security challenges in the WEB3 landscape from an infrastructure perspective, considering the three fundamental principles of blockchain: decentralization, transparency, and trustlessness.

On the front end, users send requests to JSON-RPC providers like Infura, Alchemy, or Quicknode. However, these requests are routed through a shared environment where developers lack control over data transformation at the API gateway, caching engine, blockchain nodes, and other components.

This shared environment poses the first problem as it centralizes access to the blockchain, contradicting the principles of decentralization. Additionally, the lack of transparency makes it impossible to verify responses from such APIs, further compromising the principles of transparency and trustlessness. Consequently, the security of such infrastructure relies heavily on trust, deviating from the true essence of trustlessness.

The second issue stems from the susceptibility to man-in-the-middle attacks, which malicious actors often exploit. Services such as domain or DNS registrars, JSON-RPC providers, and third-party aggregated services become vulnerable targets.

The Solution: An Autonomous Cluster of Geo-Distributed Blockchain Nodes

Is there a solution to address these challenges? Yes, the answer lies in configuring an on-premises environment that leverages a self-hosted cluster of blockchain nodes.

Firstly, establish a self-hosted cluster of blockchain nodes, ensuring all nodes are initialized from the official genesis and synchronized through peer-to-peer (p2p) communication. This guarantees data consistency across the network.

To optimize performance, periodically update the nodes with reduced snapshots. The ideal approach involves automatically creating new nodes from reduced snapshots when necessary. By following this method, setting up a new node can be accomplished within 30 minutes instead of the several days required for a full initialization.

It’s crucial to automate the update process for blockchain software following new releases. This entails creating a snapshot with the latest version, which may involve data operations taking some time. Subsequently, new nodes should automatically launch with the updated snapshot and software.

Monitoring the synchronization state and eliminating nodes lagging behind the upstream flow is equally important. Implementing health checks can aid in identifying and excluding lagging nodes.

Additionally, restricting access by IP address and implementing JWT (JSON Web Token) authentication can offer protection against domain registrar or DNS attacks. JWT tokens seamlessly integrate with web3js and other libraries, and their implementation on the API gateway side within the blockchain cluster enhances security.
