What is Blockchain?

Blockchain is a distributed database that enables the secure sharing of information, with the power to update distributed between nodes of public or private computer networks. In this section, we’ll define what blockchain is, how it works, and explore its benefits and drawbacks.

Definition of Blockchain

As previously mentioned, a blockchain is a digital ledger used to record transactions across many computers, making it decentralized, distributed, and often public. According to Wikipedia, a blockchain is a growing list of records, called blocks, that are linked and secured using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

How Blockchain Works

As explained by IBM, blockchain technology allows data to be stored across a network of computers, rather than on a central server or database. This creates a decentralized, distributed ledger that is secure and transparent.

Nodes and Consensus

Nodes are individual computers or devices connected to a blockchain network. Each node on a blockchain network has a copy of the entire blockchain ledger. When a transaction occurs, it is broadcast to all nodes on the network.

Consensus is the process of agreeing on a single version of the truth. In a blockchain network, consensus is reached by a group of nodes on the network verifying and validating the transaction. There are different methods for reaching consensus, such as private blockchains or a proof-of-work or proof-of-stake system.

Types of Blockchain Networks

As previously mentioned, there are four types of blockchain networks: public, private, consortium, and hybrid.

Public

Public blockchains are open and permissionless, meaning anyone can participate in the network. Bitcoin is an example of a public blockchain.

Private

Private blockchains consist of a permissioned network where known users verify transactions. Private blockchains are often used within an organization to improve efficiency and security.

Consortium

A consortium blockchain is a permissioned network where multiple organizations control the nodes. Consortium blockchains are often used in industries where multiple parties must agree on a transaction, such as supply chain management.

Hybrid

Hybrid blockchains combine elements of both public and private blockchains. Hybrid blockchains allow for both public and private transactions, depending on the use case.

Potential Use Cases Beyond Cryptocurrency

Blockchain technology has many potential use cases beyond cryptocurrency. As explained by Wikipedia, it can be used in supply chain management, domain name services, music distribution, insurance, peer-to-peer energy trading, and more.
