Blockchain Technology: Exploring Diverse Use Cases and Navigating Core Limitations.

Blockchain systems face limits: immutability hinders evolution, lost keys cause permanent inaccessibility, and high energy use is criticised. The network also faces storage growth issues and the 51% attack threat.

Blockchain Network Structure Explained: Full Nodes, Light Nodes, and the Role of Forks

Blockchain Network Structure Explained: Full Nodes, Light Nodes, and the Role of Forks

Explore the roles of full nodes (complete validation and storage) and light nodes (efficiency using block headers) in network structure. Learn how soft forks (backward-compatible) and hard forks (network fragmentation) introduce changes and resolve conflicts in a permissionless system.

Consensus Mechanisms

PoW vs PoS: Understanding the Two Dominant Blockchain Consensus Mechanisms

Consensus mechanisms like Proof of Work and Proof of Stake solve the Byzantine General’s Problem, ensuring decentralized nodes agree on a single truth. PoW uses resource-intensive mining, which is "expensive to produce, cheap to verify". PoS uses staked collateral to select validators.

The Cryptographic Foundation of Blockchain: Private Keys, Digital Signatures, and Transaction Validation

Blockchain is a public database used by strangers, secured by cryptography. A private key digitally signs transactions, proving authorization. The public key verifies this signature, stopping impersonation and unauthorized spending.

Understanding Crypto Exchanges: Centralized (CEX) vs. Decentralized (DEX) Trading Platforms

Explore the two main crypto exchange types: CEXs, where a trusted middleman handles assets and custody, and DEXs (non-custodial, peer-to-peer), which operate trustlessly via smart contracts on the blockchain. Beginners should start with a reputable CEX.

The Complete History of Blockchain Technology: From 1991 Concept to Modern Applications (Bitcoin, Ethereum, and Smart Contracts)

Blockchain technology began in 1991 (Habber & Stoornetta). Hal Finny introduced RP in 2004 to solve double spending. Satoshi Nakamoto launched Bitcoin (2009) using Proof of Work. Vitalik Bhuteran developed Ethereum, adding smart contracts. Applications now span healthcare, governance, and energy.

Understanding Blockchain: An Introduction to Decentralized & Tamper-Proof Digital Ledgers

Understanding Blockchain: An Introduction to Decentralized & Tamper-Proof Digital Ledgers

Blockchain is a tamper-proof database, storing data in linked blocks. New data is added via unique 'hashes' that connect blocks, ensuring immutability. Operating without a central authority, this 'trustless' distributed ledger provides a secure, transparent, single source of truth for network users
