1.⁠ ⁠Blockchain Infrastructure:
Blockchain infrastructure refers to the distributed ledger technology (DLT) that serves as the foundation of a crypto project. This infrastructure ensures data is stored transparently and securely without a central authority. Key components of blockchain infrastructure include:

Blocks: Units where data is stored.

Nodes: Computers that form the blockchain network.

Consensus Mechanisms: (e.g., PoW, PoS) Protocols that ensure the accuracy and security of the data.

2.⁠ ⁠Smart Contract Coding:
Smart contracts are self-executing programs on the blockchain that run when predefined conditions are met. They are usually written in programming languages such as Solidity, Vyper, or Rust.

Features: Secure, immutable, and transparent.

Use Cases: Payment systems, NFT trading, DeFi applications.

A whitepaper should provide a clear and detailed explanation of the blockchain infrastructure and smart contract coding. Lack of detail or ambiguities could indicate a lack of credibility.
