Blockchain technology has been named one of the most innovative and has a huge potential for development. Many experts are convinced that the technology will only begin to be fully implemented in the next decade, meaning it makes sense to learn new skills or retrain as a blockchain programmer. Large companies are already interested in using the technology, and the industry is only gaining momentum and needs specialists.
Blockchain technology did not appear yesterday, but the process of its development today is very intensive. The first widespread use of distributed ledger technology is associated with the release of the Bitcoin cryptocurrency.
However, the technology had to be modernized for the wider use of the blockchain and the conduct of complex financial transactions.
In the blockchain, the term “smart contract” is a computer code that automatically executes all or parts of an agreement. Such code specifies the conditions under which the program allows or initiates certain actions. Therefore, the input parameters and stages of execution of the smart contract must be specific and objective; that is, the program needs conditions like: “if X happens, then do Y.”
Today, smart contracts are used in the simplest and most understandable operations, for example, in issuing and subsequent automatic loan repayment. All this is done with the help of deploying smart contracts and the work of a team of programmers. The technology reduces the risk of fraud, eliminates transaction costs, and significantly reduces time costs.
How to Become a Smart Contract Developer?
There are many considerations here and no universal answer. Most dApps currently exist on Ethereum and tend to have the most liquidity. In addition, Ethereum’s significant history provides it with a reputation as a trustworthy platform. Therefore, Ethereum is a good choice if speed and low transaction costs are not your primary concerns and you have ecosystem needs (for example, the dApp you want to interact with only runs on Ethereum).
You can also deploy the system at a scalable layer (L2) such as Arbitrum, which has full EVM compatibility, but “rolls” transactions into compressed packages, so transaction throughput is higher, which means lower costs and faster speed. As for the other EVM networks, each offers some form of scalability improvement over Ethereum. Similar attributes are owned by Binance smart chain, so this can also be a review example.
Creating smart contracts is not the easiest task, but we cannot calculate the demand in the blockchain world – this is a must-have skill for working in this area.
Technical Skills of Blockchain Developer
However, a full-blown blockchain programmer must have both skills, as it is through the web3.js and ethers libraries that handle most interactions with Solidity smart contracts. A good developer can work with the Solidity contract backend developer and the JS/Python front end, but a great developer can work with the entire stack. The OpenZeppelin contract library is also a great source to use as it saves developers from having to write smart contracts, such as the tokenization contract. Building smart contracts in Solidity are not just for money transfers. They can be used for many different things. Smart contracts can be used for other transactions, from secure voting in elections to lease agreements.
As smart contracts become more complex, they become more difficult to secure. Therefore, you must know all possible ways to execute a smart contract and ensure it does what it is expected to do.
Features of Smart Contract Development
The difference between a smart contract and traditional contracts lies in an increased degree of certainty since the programming languages in which the terms of smart contracts are stated do not involve two-reading. On the one hand, this is good because everything is clear and understandable. But, on the other hand, there are complex contracts in which there is a variability of conditions, these conditions can be grouped in a different order, and each order will entail other actions.
In addition, the input parameters may not be quantitative or conditional but qualitative, and such parameters must be obtained from outside – from a resource that all parties to the contract would trust. So the development of such complex contracts is the main barrier to their large-scale distribution in the market.
Therefore, the task of the analyst, auditor, and smart contract developers is to eliminate errors in it. Otherwise, the execution of the contract threatens its parties with major losses.
Learn on Your Own From Scratch
This is possible and feasible, although it will require much time and effort.
The Internet is a huge storehouse of information about everything you can think of. However, you cannot choose any random learning resource to become a developer and start developing smart contracts. Instead, look for training courses with a detailed explanation of all topics and concepts and a practical understanding of its use.
You need courses that will teach you how to work and prepare you to use it in real applications. In addition, you need to look for platforms that offer validating credentials for your experience through certification as a sign of proficiency in at least a high-level programming language. Once you have mastered using smart contracts for development, certification can improve your chances of becoming a programmer.
Difficulties may be scattered along the way to your goal. However, dedication and a career in blockchain development can help you get ahead on even the most difficult paths.
Demand and Сareer Prospects
Blockchain is a revolutionary technology that fundamentally solves security and trust problems. All data and operations are transparent and cannot be changed or stolen. Furthermore, transactions can be carried out without intermediaries. This significantly reduces business costs, so large companies increasingly invest in this area.
Companies value their security, which is direct evidence of the high salaries of engineers and programmers who work with smart contracts. On average, salaries are $150,000 annually, but the amount may vary depending on the region and the demand for these services. For example, the highest paid region is North America, while Africa and Asia are the least. These two regions can be a good option for young professionals to start a career since the work is mostly remote.
As a rule, first of all, seniors in the field of blockchain development are invited to work, but there is always a place for middle specialists. The main conditions for obtaining the desired position are knowledge of the main programming languages, such as Solidity, and experience with blockchain and smart contracts.

Smart Contract Developer Perspectives
Undoubtedly, blockchain is the future, which is increasingly moving into the present. Companies, Internet services, and many enterprises are looking at this technology. Every entrepreneur wants to provide maximum security to businesses and customers and minimize resource waste to ensure it. Critical to gain smart contract developer skills and be a competitive programmer.
These are blockchain-based digital contracts with features superior to standard smart contracts. These smart contracts can solve the problems that standard smart contracts face. Hybrid smart contracts interact with the non-blockchain world, thus collecting data off-chain. Build smart contracts are not very different from hybrid ones but still require practice.
Developers use primary programming languages such as C++ and Java to create their programs on the blockchain. In addition, cryptocurrencies have made languages such as Simplicity and Solidity specifically designed to improve smart contract frameworks.
In simple words, a blockchain developer is a programmer who makes various products using blockchain technology or smart contract language – protocols and decentralized platforms, as well as cryptographic tools.
Smart contracts are created and deployed at the top of the blockchain. In other words, these are automated digital versions of traditional real smart contracts.
