Introduction to Blockchain Technology

Blockchain is the foundation of modern cryptocurrency and one of the most transformative technologies of the digital age. Initially created to support Bitcoin, blockchain has expanded into countless use cases, from decentralized finance (DeFi) to supply chain tracking, real-world asset tokenization, and artificial intelligence (AI) integration.

In 2025, understanding how blockchain works is essential—not just for crypto investors but for anyone navigating the evolving digital economy. This article explains the structure, components, and applications of blockchain in simple terms and explores how platforms like Token Metrics use blockchain data to help investors make smarter decisions.

What Is Blockchain?

At its core, blockchain is a distributed digital ledger that records transactions across a network of computers. Unlike traditional databases controlled by a single entity, blockchain operates on a decentralized network, making it secure, transparent, and tamper-resistant.

Each entry in this ledger is grouped into a “block,” and these blocks are linked (or chained) together in chronological order—hence the name blockchain.

Key Features of Blockchain

  1. Decentralization:
    No single entity controls the network. Instead, multiple participants (called nodes) maintain the ledger.

  2. Transparency:
    Transactions are visible to all participants, increasing accountability and reducing fraud.

  3. Immutability:
    Once data is recorded on a blockchain, it cannot be altered or deleted.

  4. Security:
    Blockchain uses cryptography to secure transactions and protect user identities.

How Blockchain Works: Step-by-Step

  1. Transaction Creation:
    A blockchain process begins when someone initiates a transaction, such as transferring cryptocurrency or executing a smart contract.

  2. Verification by Nodes:
    The transaction is broadcast to a network of computers (nodes). These nodes verify its validity using consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS).

  3. Block Creation:
    Once verified, the transaction is bundled with others into a block.

  4. Adding the Block to the Chain:
    The block is cryptographically linked to the previous one, creating an unbroken chain of data.

  5. Consensus & Finalization:
    The network reaches consensus, confirming the block as part of the permanent ledger.

Consensus Mechanisms: How the Network Agrees

Consensus mechanisms are protocols that ensure all nodes agree on the state of the blockchain.

  • Proof of Work (PoW):
    Used by Bitcoin, this method involves miners solving complex puzzles to validate transactions.

  • Proof of Stake (PoS):
    Used by Ethereum and many other blockchains in 2025, this energy-efficient model requires validators to stake tokens as collateral for transaction verification.

  • Other Models:
    Variants like Delegated Proof of Stake (DPoS) and Proof of Authority (PoA) aim to balance efficiency with security.

Components of a Blockchain

  1. Blocks:
    Contain transaction data, a timestamp, and a cryptographic hash.

  2. Nodes:
    Computers that maintain and validate the blockchain.

  3. Smart Contracts:
    Self-executing agreements coded directly onto the blockchain.

  4. Cryptographic Keys:
    Digital signatures that authenticate participants and secure transactions.

Public vs. Private Blockchains

  • Public Blockchains:
    Open networks like Bitcoin and Ethereum allow anyone to participate.

  • Private Blockchains:
    Restricted networks used by enterprises for applications like supply chain management.

In 2025, hybrid models combining public and private features are increasingly popular for balancing transparency with privacy.
