If you’re a developer looking to stay ahead of the curve and the competition, investing in new skills is essential. As blockchain technology continues to evolve, so do the skills needed to stay relevant and competitive in the field. And these skills go well beyond understanding Bitcoin.
7 of the Most In-Demand Blockchain Skills in 2023
According to a recent survey, blockchain jobs are expected to grow by more than 50% in the next three years. So, what are the most in-demand blockchain skills for developers in 2023?
1. Coding For Blockchain Platforms
One of the most in-demand skills for developers in 2023 is coding for blockchain platforms. This includes coding on platforms such as Ethereum, Hyperledger, IBM Blockchain, and EOS.
Developers will need to be proficient in coding languages such as Solidity, C++, and Java in order to develop and maintain applications on blockchain platforms. The blockchain bootcamps found at RareSkills can help developers upgrade their blockchain skills.
2. Building DApps
3. Writing Smart Contracts
Smart contracts are a type of computer program that’s stored on the blockchain and is designed to automatically execute when certain conditions are met. These conditions include buying and trading cryptocurrency or creating a legal agreement when someone buys real estate.
Developers will need to be familiar with programming languages like Solidity and Vyper in order to write and deploy smart contracts. It’s estimated that smart contracts will become common.
While the blockchain is considered safe, developers are still needed to protect applications on the blockchain. To become a cybersecurity technician in the blockchain, developers must understand how to audit systems and be knowledgeable about key security measures.
5. Understanding Cryptography
Understanding cryptography is also an essential skill for developers in 2023. Cryptography is the science of creating secure communication and transactions within the blockchain. It’s capable of securing transitions between two nodes in the blockchain network rather quickly.
Developers will need to understand the principles of cryptography, such as confidentiality, authentication, integrity, non-repudiation, and key management to be successful here.
Interoperability is the ability for computers to exchange and make use of information. For blockchain technology, this means understanding cross-chain messaging protocols. Multichain translation systems, like Polkadot, can help developers enable sidechain communication.
7. Database Management
Another important skill for developers in 2023 is database management. Blockchain technology is based on distributed ledger technology, which requires developers to understand database management systems and their software, such as MongoDB, Cassandra, and CouchDB.
To be a standout in this space, developers need to be able to create and maintain databases. It may be helpful to learn non-blockchain databases as a basis, such as SQL and NoSQL.
