- Engineers must understand data structures (trees, hash maps, Merkle trees), encryption algorithms, and networking protocols.
2. Familiarity with Decentralized Concepts
- Developers must grasp consensus mechanisms (PoW, PoS, dPoS, BFT).
- Knowledge of peer-to-peer architecture, gas fees, governance models, and tokenomics is critical.
3. Experience in Smart Contract Development
- Most blockchain jobs involve writing or auditing smart contracts.
- Proficiency in Solidity, Vyper (for Ethereum), Rust (for Solana), or Move (for Aptos) is highly valuable.
4. Ability to Work in Agile, Global Environments
- Blockchain engineering often requires asynchronous communication across countries.
- Open-source contribution and GitHub collaboration are essential assets for international hiring.
