The Green Blockchain Revolution: Sustainable Crypto for a Better Planet | by R Brunell | The Capital | Aug, 2025
I still remember the day my wife asked me about cryptocurrency, because I hadn’t deeply explored the details. Although I understood the basics of blockchain, her sister had “dove headfirst into this crypto stuff.” My sister-in-law, Kathy, for short, was what I knew to exist as perfect prey for junk coins and rug pulls. She will often explore strange Internet content. The algorithms push her deeper into questionable investment advice without her understanding of it.
My wife tried to provide user-friendly warnings for me, but my advice fell on deaf ears. I was explaining how sustainable blockchain projects differ compared to speculative schemes. Unfortunately, Kathy’s meager funds decreased to hundreds of dollars in the bank after the sale of her home. This experience strengthened my commitment to ethics, a core value that I have developed through my cybersecurity education. It motivated me to explore how we can embrace DeFi’s vision while prioritizing blockchain solutions that are ethical and environmentally sustainable.
