• Smart contracts: Programmatic execution of agreements
• Cryptocurrency: The native form of exchange on blockchain networks

Understanding Blockchain Technology

Blockchain is an innovative distributed database technology that maintains a shared, immutable ledger of transactions or data. It is a decentralized system, meaning it is not controlled by a single entity. Instead, it operates on a peer-to-peer network, where each node maintains a copy of the ledger.

How Blockchain Works

The blockchain stores transactions in blocks. Each block contains a hash of the previous block, a timestamp, and a list of transactions. When a new transaction occurs, it is broadcast to the network. The nodes on the network verify the transaction and add it to a new block. The new block is then added to the blockchain, maintaining the integrity and immutability of the ledger.

Types of Consensus Mechanisms

To ensure the validity and integrity of transactions in a decentralized system, blockchain networks employ consensus mechanisms. These mechanisms allow nodes to agree on the order and validity of transactions. Common consensus mechanisms include:

• Proof of Work: Miners solve complex mathematical problems to validate transactions. The first miner to solve the problem earns the right to add the new block to the blockchain.
• Proof of Stake: Validators are selected based on the amount of cryptocurrency they hold. Validators verify transactions and participate in the consensus process by creating new blocks.

Smart Contracts

Smart contracts are autonomous programs that run on the blockchain. They execute pre-defined conditions automatically when certain criteria are met. Smart contracts can facilitate complex transactions without the need for intermediaries, ensuring transparency and efficiency in agreements.

Cryptocurrency

Cryptocurrency is the native form of exchange used on blockchain networks. It is a digital currency that leverages the security and transparency of blockchain technology. Each cryptocurrency has its own blockchain and is used for different purposes, such as payments, asset management, and decentralized finance.
