Natural Language Processing in Blockchain Smart Contract Auditing
Blockchain technology has transformed the manner in which we perceive finance, contracts and online transactions. The smart contract is one of its greatest innovations. A smart contract refers to a computer program on a blockchain that automatically executes the contracts between parties in case of meeting some requirements. Smart contracts may save time, minimize human error, and are not flawless.
When there is a bug or vulnerability in a smart contract, one may end up losing a lot of money. That is why it is highly essential to audit smart contracts. During the last few years, I have come to know that Natural Language Processing (NLP) is emerging as a potent tool in auditing smart contracts.
Natural language processing is a subfield of artificially intelligent systems and enables computers to interpret and process human language. Conventionally, auditors go through smart contracts line by line. The process is tedious, time consuming and liable to human error. NLP can be useful in the analysis of smart contracts code and documentation, which will be performed automatically.
As one example, NLP tools can scan comments written in a code or on the whitepaper of a blockchain project and identify discrepancies between the terms of the contract and the promises of the documentation. This assists auditors to determine potential risks at a quicker pace.
Identification of vulnerabilities in the code is one of the ways NLP is applied in the auditing profession. Smart contracts are also developed in programming languages such as Solidity. The algorithms are also able to run NLP on the code in the form of a text, which identifies patterns or phrases previously known to cause issues.
As an example, one can indicate the repetitive or ambiguous structures of code that can be raised to be reconsidered. I heard that even in NLP, it is possible to determine the probability that a contract is going to fail depending on the same patterns observed in previous adventures. This proves to be very helpful as there is always a possibility of missing out on harmful bugs.
The other notable use of NLP is in checking compliance. Technologies based on blockchain may be required to comply with legal and regulatory provisions. The text of regulations can be read and compared with the code used in the contract using NLP to check whether it accomplishes the requirements.
This can save many hours to the auditors and developers. It also assists in shielding the investors and users against committing to risky and even illegal contracts. I am quite interested in this application as it is a combination of law, technology, and finance.
Reporting can also be enhanced by use of NLP. Following an audit of a smart contract auditors are required to develop reports to clarify their investigation. NLP is also able to condense high volumes of technical data into easy language comprehensible by non-technical consumers.
Such transparency also plays a crucial role in the development of blockchain technology as users can have more confidence in the projects they know how their money is secured. In my opinion, tools that simplify and improve the results of audits will be highly appreciated as more individuals get to know about blockchain.
However, NLP does not have only positive sides. Smart contracts are quite complicated and NLP tools may also be mistaken in case the information is inaccurate or the language in which the code is written is not common.
Human auditors should therefore not be fully relieved by NLP. Rather, it must be viewed as an aid to help auditors, and it would be more expeditious and accurate. A system of intelligent contract auditing can be developed by combining NLP with human expertise.
To sum up, Natural Language Processing is emerging as an important tool in smart contract auditing of blockchains. It assists in identifying weaknesses, adherence to regulations, and enhances user and investor reporting. I have found that NLP may save time, minimize mistakes, and enhance trust in blockchain projects.
It may not fully substitute human auditors but it can collaborate with them to build safer and more trustworthy smart contracts. With the rise of the blockchain technology, I think that NLP will remain a significant factor towards ensuring that smart contracts are secure and trustworthy.
