How can Blockchain be Used to Support Sustainable Business Practices?

In the contemporary business landscape, sustainability has emerged as a critical priority. Companies are increasingly seeking innovative solutions to enhance their environmental, social, and economic impact. Blockchain technology, often associated with cryptocurrencies, offers promising opportunities to support sustainable business practices. This article explores how it can be leveraged to foster sustainability, addressing its potential applications, benefits, and challenges.

What is Blockchain?

Blockchain is a decentralized digital ledger that records transactions across multiple computers. Its key features include transparency, immutability, and security, making it a reliable system for recording and verifying transactions without the need for a central authority.

How Blockchain Works

It operates through a network of nodes (computers) that validate and record transactions in blocks. Each block is linked to the previous one, forming a chain. This structure ensures that once data is recorded, it cannot be altered retroactively without altering all subsequent blocks, which is practically impossible.
