Complete Understanding of Cryptography
Cryptography is a vital part of blockchain technology as it enhances the security of the distributed ledger system. Cryptography uses various coded algorithms to obscure and protect sensitive information transmitted across the network. It only allows the primary owner to read and decrypt the information, limiting interaction of unauthorized parties.
In simpler words, cryptography ensures that all the data across the blockchain network cannot be altered by any third parties. Even the most trivial changes are noted in the system, giving the recipient and receiver full transparency.
Therefore, a blockchain professional must showcase a comprehensive understanding of cryptography. Since it is a blend of multiple traditional and modern techniques, some Blockchain professionals may not understand it too well. However, since it is the basic element of the blockchain system’s security, a solid grasp of its fundamentals is imperative.
Expertise in Blockchain Architecture
One of the chief pillars of blockchain is its architecture. In order to be a successful blockchain professional, having a firm grasp of concepts like peer-to-peer networks helps you build a strong foundation.
To start off, understand the basic definition of blockchain. It is a distributed database that paves the way for secure, transparent, and tamper-free transactions. It involves a node-to-node (peer-to-peer) network that approves these transactions, entirely eliminating the need for a third party. This is the main reason why blockchain is becoming increasingly popular for businesses, as it minimizes costs and improves efficiency.
The candidate must also know about different types of blockchains. For instance, building an application based on Ethereum requires skills different from those of Cosmos. Moreover, blockchain professionals should also know about the latest relevant technologies, such as consensus mechanisms, distributed ledgers, etc.
Command Over Smart Contracts
Blockchain professionals must also be proficient at handling smart contracts; these are digital self-executing contracts that automatically go through when the predetermined conditions are met.
These terms and conditions are agreed upon between parties and written into codes. Whenever a transaction meets these conditions, the smart contract is enabled. Once the contract is deployed, it also does not need any external (third) party approval.
One of the most useful and powerful features of blockchain is smart contracts, as they separate it from other standard databases. Blockchain developers who know how to write smart contracts have an advantage over others and are most likely in higher demand.
Here are the main advantages of smart contracts in blockchain:
- Full transparency
- Higher efficiency
- Increased trust
- Reduced costs
- Improved security
- Immutability
- Immediate execution
- Greater accuracy
- Large storage and backup

Proficiency in Blockchain-Specific Programming Languages
The most common programming languages used in the blockchain industry include C++, Golang, JavaScript, C#, Solidity, Python, and Java. Only Solidity is specified to Ethereum. The rest of the programming languages are for general use and may be used for building numerous multi-purpose applications and other software. However, Solidity still has a lot of uses since it is user-friendly and flexible.
Solidity also has high accuracy, providing a reliable and secure medium for the transaction of smart contracts between two parties. It also supports Application Binary Interface (ABI), offering multiple type-safe functions.
Knowledge of Peer-to-Peer and Distributed Systems
Two other important components of blockchain are peer-to-peer and distributed systems. Blockchain is made of a decentralized system that is transparent and secure. It does not give control to a single entity but allows all involved members to make authorized changes.
The peer-to-peer system basically keeps a record of each transaction. The nodes (computers) keep a copy of the ledger and verify transactions with other nodes to ensure that the data input is authentic and accurate.
Blockchain’s distributed system allows all the computers connected through the network to coordinate and communicate with one another. The blockchain system is decentralized, so there is no central point of failure or control.
In a typical blockchain network, all the involved nodes are considered peers. The central system minimizes the need for third parties, frauds, failures, and hacking. A good blockchain developer must be familiar with all these concepts to excel in their career.
The peer-to-peer network in the blockchain system also acts as a decentralized ledger for digital assets, which means it is a safe platform for the owners.

Experience with Algorithm and Data Structures
The entire blockchain system is based on algorithms and data structures. The most popular blockchain database systems are UTXOs (Bitcoin) and account/balance (Ethereum). Blockchain professionals must be aware of these concepts and their applications on various platforms.
Algorithms in the blockchain system are necessary as they tell the computers integrated into the network what to do. Algorithms are involved in performing tasks and resolving relevant issues. The most commonly used algorithms on the blockchain network are Proof of stake, Proof of Work, and Delegated proof of stake.
A blockchain professional should be proficient at writing algorithms for the following purposes:
- Ensures balance
- Validates and allows new transactions that can be written on a blockchain
- Helps with implementing consensus protocols
- Allows for verification of digital signatures
- Writes applications using data stored on the blockchain network
A computer scientist considers the blockchain system as a data structure. It stores information securely, reliably, and efficiently. The concept of data structure allows users on the blockchain network to store large amounts of data without the fear of loss or hacking. It allows only the primary users to edit, delete, or add to the data, which is why it is an essential part of Blockchain.
