Solidity (Ethereum)
-
Rust (Solana, Polkadot)
-
Vyper (Ethereum alternative)
💡 How Cognitive Helps:
-
Hands-On Learning: Online labs and project-based training allow learners to build and deploy their own smart contracts.
2️⃣ Blockchain Architecture and Protocols
Understanding the underlying architecture is essential for designing secure and scalable blockchain solutions.
What to Learn:
-
Consensus mechanisms (PoW, PoS, PBFT)
-
Blockchain types (public, private, hybrid)
-
Layer 1 and Layer 2 scaling solutions
💡 How Cognitive Helps:
-
Programs: Hyperledger Fabric training by the Linux Foundation
-
Simulations: Cognitive Networks provide blockchain network simulators to practice node setup and protocol testing.
3️⃣ Cryptography and Security
Blockchain relies on cryptographic techniques to ensure data integrity and security.
