Origins and Fundamentals
Blockchain technology traces its roots back to a white paper published in 2008 by an anonymous entity known as Satoshi Nakamoto. The paper introduced Bitcoin, the world's first cryptocurrency, and the underlying technology - the blockchain. The Blockchain Marvel
The decentralized and distributed nature of a blockchain is what sets it apart from traditional centralized databases. In a blockchain, there is no single point of control or failure, as the ledger is replicated and synchronized across a network of computers, known as nodes. Each node maintains a copy of the entire blockchain, ensuring redundancy and fault tolerance.
When a new transaction occurs, it is broadcasted to the network and grouped with other transactions into a block. Before being added to the blockchain, this block undergoes a consensus mechanism, where network participants nodes validate and agree on the validity of the transactions within the block. This consensus process ensures that only valid transactions are recorded on the blockchain, maintaining the integrity and accuracy of the ledger.
Once a block is validated by the network, it is cryptographically linked to the previous block, forming a chain of blocks—hence the term blockchain. This linkage creates a chronological and immutable record of transactions, where each block contains a reference to the previous block, making it computationally infeasible to alter past transactions without invalidating subsequent blocks. This decentralized architecture ensures transparency, security, and censorship resistance, as no single entity controls the entire network.
