Blockchain technology brought an entirely new concept of decentralization, transparency and security to various industries. It has the potential to revolutionize how data is stored and shared. Blockchain is one of the safest and most secure ways to transfer information and money, but it also has its pack of threats and flaws.

This article will tell about the 4 hidden and rarely-discussed security threats of blockchain and the blockchain security features. Let’s not wait any longer and discover what makes blockchain technology insecure.

What are Blockchain Security Threats?

The world of blockchain and security is constantly under threat from hackers and malicious actors looking to exploit vulnerabilities in the system. The security blockchain ecosystem faced four high-profile attacks that, for some reason, were kept hidden for a while from the public eye. Here are the details of these blockchain threats:

  1. Dealing with Scale: The first threat of this list that the security blockchain has faced is the way it deals with the scale of data. In fact, it has limited capacity, making it vulnerable to high-scale data transfer, causing crashes or long period waits. The solution found is the integration of new technologies like AI and improved inter-blockchain communication to maintain efficiency.

  2. Not-So-Smart Contracts: Smart contracts are computer programs that are part of blockchain security technology. They execute specific actions automatically, but these smart contracts can encounter problems due to the way they are programmed. One such issue is called "Re-entrancy", which can create a loop leading to the incorrect movement of money.

  3. Secret Chains & Selfish Mining: Another vulnerability in the list of blockchain security threats is selfish mining. Selfish mining is a fraudulent method that directly attacks the blockchain tamper-proof side. It consists of secretly making transactions in a hidden chain. When the hidden chain gets more extended than the real one, the original chain becomes useless.

  4. Secret Tokens: Double spending is one of the most used scams on the blockchain. It consists of sending tokens from one wallet to 2 different other wallets simultaneously. The purpose of this practice is to duplicate your assets. Still, thanks to the evolution of blockchain security analysis and the combination of cryptographic techniques and network consensus mechanisms, it is now almost impossible to duplicate the same token.

Keep in mind that this goes against the transparency and honesty of blockchain, and it is illegal. We suggest you avoid engaging in any fraudulent activities related to blockchain technology.

What Makes Blockchain Technology Secure?

What makes a blockchain secure? Blockchain is secure due to several fundamental features that we are going to see in detail here:

  • Cryptography: The main aspect of the blockchain in security is cryptography. Unlike traditional databases that are controlled by a single entity, blockchain is distributed across a network of computers, making it more resilient against threats to blockchain.

  • Decentralization: Another factor that influences securing blockchain is its decentralization aspect. Every transaction on a blockchain is secured using cryptographic algorithms. Each block contains a unique hash, and this blockchain security system makes the act of altering any information almost impossible.

  • Consensus Mechanisms: Before adding a new block to the chain, it must be validated by multiple nodes through a consensus mechanism, such as Proof of Work (PoW) or Proof of Stake (PoS). These mechanisms ensure that all nodes agree on the state of the blockchain, preventing fraudulent transactions from being added and improving at the same time the blockchain protection.

4 Hidden and Rarely-Discussed Security Threats of Blockchain

Blockchain Security Threats Analysis

Now that we have seen what blockchain security is and what the main factors that make the blockchain tamper-proof, let's talk in detail about the impact of the 4 blockchain threats we saw earlier:

  1. Dealing with Scale: The scalability challenges of blockchain impact its ability to serve as a global ledger. Processing speed and capacity limitations can lead to blockages, degrade performance, and compromise security. These issues threaten the trust in the blockchain's ability to process transactions.

  2. Not-So-Smart Contracts: Smart contract vulnerabilities can cause massive financial losses and erode trust in the blockchain ecosystem. To avoid such incidents, rigorous security audits and practices are critical in smart contract development.

  3. Secret Chains & Selfish Mining: Secret chains and selfish mining violate the foundational principles of blockchain. These practices can centralize control of the network, eroding its decentralized nature and risking fraudulent transactions. This could harm the blockchain's growth and innovation.

  4. Secret Tokens: Double-spending attempts have occasionally been detected and prevented. The assaults usually result in theft rather than double-spending. But the impact that double-spending can cause the destruction of the technological grounding on which a blockchain is founded.

Benefits of Blockchain for Managing Security Threats

Blockchain technology offers benefits in managing security threats in its ecosystem. Here are some of the benefits of a blockchain security system:

  • Enhanced Security through Cryptography: Blockchain secures data using advanced cryptography that makes it difficult to hack or alter. The transactions are encrypted and linked, forming a secure chain of blocks and minimizing the risk of fraud and unauthorized access.

  • Decentralization: Blockchain's distributed network of computers eliminates single points of failure and reduces the risk of centralized data breaches. This enhances the security and resilience of information systems.

  • Transparency and Traceability: Blockchain's transparency and immutability enhance traceability, making it easier to track and verify transactions, thereby preventing fraudulent activities in real time and enhancing overall security.

Tips of Using Blockchain for Dealing with Security Threats

To make your crypto journey safer and smoother, you need to know and learn how to avoid and protect yourself from blockchain security threats. Here are some tips that will help you achieve that:

  • Regular Audits and Security Reviews: Regularly audit blockchain and smart contracts, using automated tools and expert reviews to ensure secure code.

  • Implement Robust Access Controls: Use strong access control with multi-factor authentication and hardware security modules to manage blockchain network change authorization.

  • Stay Updated with Security Patches: It is essential to keep the blockchain platform and all related software up to date with the latest security patches. Regular updates can protect against newly discovered vulnerabilities and improve overall system security.
