8 Best Blockchain Security Projects to Learn From

With its decentralized, transparent, and immutable approach to solving various problems, blockchain technology has become a game changer in many industries. As it has gone upwards, the question of security has also risen and has led to the creation of bull-strong security measures, and specialization in projects to secure blockchain networks. This blog gets into the nitty-gritty of blockchain security detail, 8 notable projects and companies that currently serve the niche, accompanied by best practices, and key takeaways.


Overview of Blockchain Security


Blockchain security is crucial due to the decentralized nature of the technology, which distributes control across a network of nodes rather than a single central authority. This decentralization, while enhancing transparency and reducing the risk of centralized failure, introduces unique security challenges. The main security aspects in blockchain include consensus mechanisms ensuring all nodes agree on the blockchain's state, cryptographic security protecting data integrity and user anonymity, smart contract safety preventing vulnerabilities in automated, self-executing contracts, and network security defending against attacks such as Sybil, DDoS, and 51% attacks.


The need for specialized security measures has given rise to numerous blockchain security projects and companies dedicated to securing this technology.

Notable Blockchain Security Projects and Companies


1. Chainalysis


Chainalysis is the global leader in the blockchain analysis field. It creates data and analysis tools for governmental agencies, exchanges, and financial institutions. The company produces tools for tracking and checking illegal deals on the blockchain.


Chainalysis was right at the core of the Mt. Gox heist, one of the biggest bitcoin heists in history. At just one single point, Mt. Gox held the rank of number one most popular bitcoin exchange in the world before it declared itself bankrupt in 2014, after losing 850,000 bitcoins, roughly $450 million at the time. The blockchain analytics by Chainalysis helped, among other things, in the tracking of some of the stolen bitcoins, where a number of arrests and continual recovery missions arose thereafter.


What to Learn


  • Importance of Transaction Monitoring: Strong monitoring of transactions is necessary to identify and prevent any kind of illegal activities that could be involved, such as money laundering and fraud.
  • Security Data Analytics: Advanced tools of data analytics, coupled with visualization tools, shall be used to trace and analyze the blockchain transactions. This will ease the early detection of any suspicious activities and thus enhance collaboration with law enforcement.
  • Regulatory Standards Compliance: Tools developed to meet the regulatory standards. This reduces the chance of lawsuits and therefore raises security to much higher levels.

3. CertiK


CertiK is a blockchain and smart contract auditing service using formal verification in proving, with the use of mathematics, the correctness and security of smart contracts.


As was the case with CertiK, which conducted an audit of Binance Smart Chain, they discovered critical vulnerabilities and further secured the network from potential exploits. This involved auditing more than 200 smart contracts, and indeed, its findings went a long way in repairing the BSC to enhance security at large.


Besides, CertiK has audited and raised the security of over 1000 blockchain projects locked in more than $10 billion in TVL across a variety of DeFi protocols.


What to Learn


  • Smart Contract Auditing: Smart contract auditing, to be done with formal verification techniques, guarantees the security and correctness of blockchain applications before deployment.
  • Mathematical Proving: Mathematical proofs seem to hold very good potential for the formal modeling, analysis, and verification of any potential vulnerability existing in smart contracts.
  • Real-time Security Monitoring Platforms: Use platforms such as CertiK Skynet to support constant auditing and real-time threat detection for blockchain projects.


4. Quantstamp


Quantstamp provides automated smart contract auditing services, applying both static and dynamic types of analyses.


For instance, Quantstamp had audited Ethereum 2.0's important deposit contract for security before the much-anticipated upgrade for the Ethereum platform had been expected to launch. The audit was treated as a due diligent exercise in the testing and verification processes to confirm the security of the deposit contract and safety of the billions of dollars in the ETH to be minted and dispensed.


In addition, Quantstamp has secured more than $45,000,000,000 in digital assets to date through its audits on over 200 projects, including major DeFi platforms like Maker and Compound.


What to Learn


  • Decentralized security audits: The use of a decentralized network of security professionals for comprehensive review and audits of smart contracts can boost the overall thoroughness and reliability of security assessments.
  • Automated Tools: Automated security tools can themselves identify and remediate vulnerabilities in blockchain applications by integrating them with manual reviews.
  • Community Involvement: This would engage the global community of security experts into the auditing processes, where their different perspectives can bring to light improved security for blockchain projects.


5. OpenZeppelin


OpenZeppelin offers a complete suite of tools and frameworks for building secure smart contracts, including libraries, audit services, and best practices.


For example, the contracts library from OpenZeppelin is one of the most widely used in the DeFi space. Compound, the second largest DeFi platform, with more than $10 billion in assets locked away, relies on OpenZeppelin Contracts in its smart contracts. And, of course, OpenZeppelin's work in security audits has further reassured Compound's very large user base.


Furthermore, OpenZeppelin has conducted over 250 audits, with its libraries being downloaded over 1.5 million times, indicating the wide adoption and trust in the solutions offered.


What to Learn


  • Smart Reusable Contract Templates: Develop secured smart contacts with reusable templates, making the development process easier and mitigating vulnerabilities.

6. Trail of Bits


Trail of Bits provides high-end security services for blockchain-based projects, such as smart contract audits, cryptographic research, and vulnerability assessments.


For example, Trail of Bits conducted a security audit of the Libra blockchain project initiated by Facebook, which is now Diem. The team identified critical security flaws and conducted an audit with consequent key improvements of project design and development of the security architecture before going public.


So far, Trail of Bits has completed over 200 security engagements for blockchain projects and secured billions of dollars in digital assets across many different protocols.


What to Learn:


  • Comprehensive Security Assessment: Perform comprehensive security testing, smart contract audits, and penetration testing to identify and remediate potential vulnerabilities.
  • By combining both the dynamic analysis and static tools, the smart contract code can be thoroughly scrutinized for security issues from a wide perspective.
  • Collaboration: Collaborating and working together with all major blockchain platforms and the larger security community can only help to further solidify the network security posture.


7. SlowMist


SlowMist is a security audit company for blockchains, risk management services, as well as anti-money laundering. It boasts detailed security reports and processes in threat detection.


For instance, the SlowMist security team identified several bugs in diversified blockchain projects, and by way of example, found a serious problem in the EOS blockchain that can be utilized to rob users' funds. The problem was recorded by the system and fixed right away so that the potential loss of funds might not happen.


More than 1,500 smart contracts and blockchain projects have been audited in SlowMist; the amount of digital assets under protection exceeds $50 billion.
