Understanding Blockchain Fundamentals
Before diving into specific courses, it’s crucial to grasp the core concepts of blockchain technology. At its heart, a blockchain is a distributed, immutable ledger. “Distributed” means the ledger is replicated across many computers, making it resistant to single points of failure. “Immutable” signifies that once data is recorded, it cannot be altered, ensuring data integrity.
Key terms to comprehend include:
- Blocks
- Hashing
- Cryptography
- Consensus Mechanisms
- Smart Contracts
Containers of data that are chained together. Each block contains a hash of the previous block, linking them chronologically.
A cryptographic function that converts data of any size into a fixed-size string of characters. It’s a one-way function, meaning it’s computationally infeasible to reverse the process and obtain the original data from the hash.
The art of secure communication, often involving encryption (converting data into an unreadable format) and decryption (converting it back). Blockchain uses cryptography for security, authentication. Verification.
Algorithms that allow the distributed nodes to agree on the validity of new blocks added to the blockchain. Common mechanisms include Proof-of-Work (PoW) and Proof-of-Stake (PoS).
Self-executing contracts written in code and stored on the blockchain. They automatically enforce the terms of an agreement when predefined conditions are met.
