Top Blockchain Programming Languages and Why You Should Use Them for Projects With the Highest Security Demands

In code we trust! This motto characterizes the most consistent supporters of distributed registry and cryptocurrency technologies. The main goal of the idea is to remove the army of security intermediaries and replace them with program code. Successful Bitcoin blockchain examples prove this is possible. The blockchain algorithm makes it virtually invulnerable to hacking. In this article, we have compiled a list of blockchain programming languages and explained why they are used to obtain the highest levels of security and safety.



Object-Oriented Languages


Experts say that P2P networks can be written in different programming languages, but as a rule, the following languages are used the most.  




This is a low-level programming blockchain language. This technology is almost never used for mobile and web apps but it is one of the most reasonable solutions for blockchain project creation.




The syntax of this language is similar to the syntax of C++, but otherwise they ​​have little in common. Java is an interpreted language: an internal representation (bytecode) and an interpreter of this representation are defined for it, which is already available on most platforms.


The interpreter simplifies debugging for programs written in Java, and ensures their portability to new platforms and adaptability to new environments. It eliminates the influence of Java programs on other programs and files available on the new platform, and thereby ensures security when executing.


These properties of Java make it possible to use as the main programming language for programs distributed over networks (in particular, over the Internet). This is the reason why Java can be used as a blockchain coding language.




Python is one of the most easy-to-use programming languages, but its potential still continues to unfold. It can be successfully used as a blockchain programming language. In particular, Python perfectly processes numbers. It can accept large data sets, clean, process, analyze, and visualize them. These benefits are very well suited for industries that deal with big data processing, such as finance (take a look at a project already we created here) and IoT. This is also the reason why Python is one of the programming languages used for aerospace project creation.




Solidity is a JavaScript-like object-oriented language for developing smart contracts. Contracts are used in Ethereum blockchain coding and they have a very important feature: each line of code, each team and even simply storing data has its own specific value (ETH).




Simplicity is a new programming language designed to be an alternative to the existing languages used to create smart contracts. It is assumed that Simplicity can be implemented over time in the Bitcoin protocol through the soft fork mechanism. One of the main advantages of Simplicity, according to the creators, is the ability to create a safe, efficient and functional code of "smart contracts".


Simplicity is significantly superior in functionality to the Bitcoin scripting language and, due to its capabilities, is more like Java or Python. Simplicity also provides the ability to change the smart contract code after it is activated. This is a major breakthrough, since the main problem of existing smart contracts from Solidity is their immutability, even in the event of an error. With the new architecture, developers will be able to change contracts if consensus has been reached, making the technology possibly the best programming language for blockchain.



Functional Languages


As the blockchain industry develops, more and more infrastructure projects are turning to the so-called declarative paradigm, in particular, to functional programming languages. Among such projects are Ercoin, Arwave, Helium, and others. Popular functional languages with elements of other paradigms are OCaml, Erlang, Elixir, Scala, F#, Clojure, and Scheme. Among the purely functional programming languages, the most used are Haskell and Elm.




In Haskell, values start to be calculated only when really needed. It is possible to declare a list of 9000 elements, but if you need only one of them (and it will not depend on other elements of the list), then the value of only that one element will be calculated. This principle is in many ways similar to the work of the blockchain network itself, which makes this language almost ideal for blockchain projects.




Increasingly, applications are built in such a way where they do not have a global state that is arbitrarily changed by different parts of the code. The programming language Elm implements this approach while being pure, functional and reactive.



When Safety Is Paramount


Aviation is currently one of the safest and most sophisticated systems in the world. Most of the emergencies that occur in aviation and lead to death and destruction of property are associated with human errors. Blockchain adoption in aviation is one of the possible ways to minimize the influence of the human factor in aviation, and the following case studies confirm this theory.


Blockchain as an Instrument Against Falsification of Data in Aviation


Aeron is a technological blockchain-based startup whose goal is to preserve the lives of passengers during flights. Its creators claim that the main problem in the modern aviation industry is the deliberate distortion of information on flight hours, in order to save significant costs for the maintenance of the airline. A decentralized, unchangeable registry will help prevent falsification of flight data, aircraft maintenance records, and tracking of spare parts.


Blockchain storage will simplify the detection of any inappropriate or falsified data for aviation supervisors. As soon as the journal entries of the aircraft or pilot are stored in a separate registry unit, they cannot be changed or forged, and are available for public audit.


The system will allow supervisors to track pilot experience and verify aircraft maintenance (service life, technical specifications, scheduled replacement of spare parts) in accordance with the required standards. Therefore, pilots will receive an electronic, transparent and secure reporting system (flight logs), and passengers and other interested users will have access to a proven global database.


Blockchain as a Way to Manage Cargo in Aviation


Swissport International AG has set a goal to use blockchain technology to track the movement of commercial and passenger cargo. For this, a contract with the companies Winding Tree and Olam was signed.


When moving goods, transparency and openness of documentation are key requirements. The platform will allow all parties to interact in a decentralized, secure and trust-based environment. They have also planned for this approach to help prevent the movement of prohibited and dangerous goods, and make air transportation even safer and more reliable.


Blockchain-Based Autopilot


The largest air corporation, Boeing, intends to create a joint project with the company SparkCognition, which specializes in artificial intelligence technology. The parties intend to work together on control technology for unmanned aerial vehicles based on artificial intelligence and blockchain. They plan to develop technologies that can control the flight of aircraft, develop and track their route, as well as calculate the trajectories of motion and choose safe corridors. The project participants also intend to develop a standardized software interface to support technology, conduct inspections, and for other commercial applications.





Despite the fact that P2P networks can be created with almost any technology, there are some languages that fit the needs of blockchain projects more than others. The usefulness of these languages relies on the fact that they enable programmers to realize the demands for the highest security and safety. This is why various blockchain projects are increasingly created for aviation and other industries where the lives of people are the top priority.
