If we compare this to the UK, the country’s total electricity consumption was 330 TWh in 2020 according to the government’s most recent data. Cryptocurrencies have been widely criticised as computers used for mining consume lots and lots of energy, although it’s unclear exactly how much is used. The concept of cryptocurrencies might sound pretty complicated, but it’s all crypto and blockchain articles quite easy to understand once you break it down. Coli, salmonella, and listeria; in some cases, hazardous materials were accidentally introduced to foods. In the past, it has taken weeks to find the source of these outbreaks or the cause of sickness from what people are eating. Every miner starts with a nonce of zero, which is appended to their randomly-generated hash.

Financial institutions are exploring how they could also use blockchain technology to upend everything from clearing and settlement to insurance. These articles will help you understand these changes—and what you should do about them. Take an introductory course on Coursera to start building your knowledge base and find the right fit for you. As opportunities in blockchain technology continue to grow, you can develop your skills in line with the industry.


There’s no correlation between JPM Coin and Bitcoin, or other cryptocurrencies for that matter. What we can talk about is the double standards of financial institutions —especially most Wall Street banks— when they first criticized cryptocurrencies and their technology. Now they’re ironically building and capitalizing on this technology, offering blockchain-based services and tokenization of assets, something that the DeFi space was already doing years ago. Cryptocurrency is decentralized digital money that’s based on blockchain technology. You may be familiar with the most popular versions, Bitcoin and Ethereum, but there are more than 9,000 different cryptocurrencies in circulation. Theoretically, a decentralized network, like blockchain, makes it nearly impossible for someone to make fraudulent transactions.

Traditional brokers tend to offer low trading costs but fewer crypto-specific options than cryptocurrency exchanges. Cryptocurrency is digital currency that doesn’t require a financial institution like a bank to verify transactions. In recent years it has become a topic of discussion from high profile business people like Elon Musk. Blockchain announcements continue to occur, although they are less frequent and happen with less fanfare than they did a few years ago. Still, blockchain technology has the potential to result in a radically different competitive future for the financial services industry.

Speed and Data Inefficiency

Storing them on blockchains would ensure they are traceable, transparent, unchangeable, auditable, and secure. Earlier this year, BlackRock chief executive Larry Fink described tokenisation — which involves digitising traditional assets and placing them on a blockchain — as the “next generation for markets”. In 2021, the number of crypto-related jobs posted on LinkedIn grew by 395 percent over the previous year [4]. The industry has more than doubled in size in a single year—most of which occurred during a pandemic.

It gives anyone access to financial accounts, but allows criminals to transact more easily. Many have argued that the good uses of crypto, like banking the unbanked world, outweigh the bad uses of cryptocurrency, especially when most illegal activity is still accomplished through untraceable cash. This is expected to increase network participation, reduce congestion, and increase transaction speeds.

Streamlining the supply chain

At its core, blockchain is a distributed digital ledger that stores data of any kind. A blockchain can record information about cryptocurrency transactions, NFT ownership or DeFi smart contracts. How these new blocks are created is key to why blockchain is considered highly secure. A majority of nodes must verify and confirm the legitimacy of the new data before a new block can be added to the ledger. For a cryptocurrency, they might involve ensuring that new transactions in a block were not fraudulent, or that coins had not been spent more than once. This is different from a standalone database or spreadsheet, where one person can make changes without oversight.
