How may the blockchain's environmental impact be reduced?

This issue of Carbon Black is focused on finding strategies to lower the carbon footprint of Bitcoin and other digital currencies. Though the technology that underpins blockchain is energy-intensive, it is getting more environmentally friendly with each passing day.

Using NFT art, you may create a digital work of art that is protected by a tamperproof, blockchain-encrypted certificate. The owner is provided with a non-fungible token (NFT) in order to verify that he or she is the lawful owner of the artwork in question. This is a revolution since it is the first time that original artwork can be accompanied by a legal title of ownership. During our interview with John Karp, co-author of "NFT Revolution," we discuss ways to make NFTs and the blockchain more ecologically friendly.

Why Energy Concerns Around Blockchain May Be a Misconception

Blockchain has made headlines recently for using more energy than airlines or even entire countries. Different types of chains have different impacts on the environment based on how they're designed. The proof-of-stake (POS) model is significantly more energy-friendly than the traditional Proof of Work (POW) model. Blockchains operate differently than traditional IT systems. Different types of chains have different impacts on the environment based on how they're designed. Proof-of-work (POW) is what's behind traditional "mining," where miners compete to solve a mathematical puzzle. The Bitcoin Foundation has switched to a more energy-friendly model of proof-of-stake. Proof-of-stake (POS) requires those working on the chain to have skin in the game. POS also reduces power consumption and accelerates the handling of transactions. The model is being adopted by big names in the industry such as Bitcoin, & Ripple.

Understanding the technology underlying cryptocurrencies

Blockchain technology could prove transformative for industries, including financial services. A primer on technology, sponsored by the Organization for Economic Co-operation and Development, was recently published. It highlights the array of opportunities and challenges that blockchain's popularity could have on the financial industry, among many other fields. A blockchain is a shared ledger of transactions between parties in a network. It can diminish the role of intermediaries in the transfer of data. The Organization for Economic Cooperation and Development (OECD) sees far-reaching potential for blockchain in the global economy. Blockchains can vary in the way they operate. One of the prime strengths of a blockchain is its immutability. Once a transaction is made to the ledger, it can not be undone. The first U.S. bitcoin futures exchange-traded fund became available in October 2021. Forty percent of fund selectors report that clients are increasingly demanding cryptocurrency
