Crypto Fundamentals

Blockchain is a distributed database where data is stored in blocks chained together. Each block contains the cryptographic hash of the previous block, making data tampering practically impossible.

Key Features:

• Distributed: Data is stored across thousands of nodes, not a single server.
• Immutable: Once written, data cannot be reversed or changed.
• Transparent: All transactions can be viewed by anyone.
• Consensus: Nodes agree on the validity of transactions.

Mining is the process of verifying transactions and creating new blocks on the blockchain. Miners solve complex mathematical problems to secure the network and are rewarded with newly created cryptocurrency.

Proof of Work: The consensus mechanism used by Bitcoin. Requires high processing power.

Proof of Stake: A more energy-efficient alternative used by Ethereum 2.0. Validators lock their assets to secure the network.

Staking is the process of locking your cryptocurrency to support a blockchain network's security. In return, you earn regular rewards — think of it as interest income in the digital world.

Staking Benefits:
• Earn regular staking rewards
• Contribute to network security
• Much less energy consumption than mining
• Easily stake on the DRC-X platform

Smart contracts are digital agreements that automatically execute when pre-programmed conditions are met. They run on the Ethereum blockchain and form the foundation of the DeFi ecosystem.

Use Cases:
• DeFi protocols
• NFTs (Unique digital assets)
• DAOs (Decentralized Autonomous Organizations)
• Insurance, real estate, and supply chain
