Welcome to our collection of blockchain tutorials! Here, you will find a variety of resources to help you understand the basics and advanced concepts of blockchain technology.

Basics of Blockchain

  • What is Blockchain? A blockchain is a decentralized ledger that records transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.

  • How Does Blockchain Work? Blockchain works by creating a chain of blocks, where each block contains a list of transactions. These blocks are linked together using cryptographic hashes, creating a secure and transparent system.

Advanced Topics

  • Smart Contracts Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They run on blockchain platforms like Ethereum.

  • Consensus Mechanisms Consensus mechanisms are protocols that enable consensus in a distributed system. Common mechanisms include Proof of Work (PoW) and Proof of Stake (PoS).
