At a time when the world is desperately trying to reduce energy consumption, Bitcoin uses more energy each year than medium-sized nations such as Argentina. If the Ethereum switch succeeds, Bitcoin and other cryptocurrencies will be under immense pressure to deal with this problem.
Why are cryptocurrencies so polluting? Cryptocurrencies are digital currency systems in which people make direct online payments to each other. Unlike traditional currencies, cryptocurrencies are not managed from a single location such as a central bank. Instead, they're managed by a ' blockchain ': a decentralized global network of high-powered computers. These computers are known as 'miners'. The Reserve Bank of Australia provides this simple explanation of how it all works edited for brevity : Suppose Alice wants to transfer one unit of cryptocurrency to Bob.
Alice starts the transaction by sending an electronic message with her instructions to the network, where all users can see the message. The transaction sits with a group of other recent transactions waiting to be compiled into a block or group of the most recent transactions. The information from the block is turned into a cryptographic code and miners compete to solve the code to add the new block of transactions to the blockchain.
Once a miner successfully solves the code, other users of the network check the solution and reach an agreement that it's valid. The new block of transactions is added to the end of the blockchain, and Alice's transaction is confirmed.
This process, used by most cryptocurrencies, is termed 'proof-of-work mining'. The central design feature is the use of calculations which require a lot of computer time — and huge amounts of electricity — to perform. Bitcoin alone consumes around terawatt-hours of electricity each year. Producing that energy emits some 65 million tonnes of carbon dioxide into the atmosphere annually — about the same emissions as Greece. Research suggests Bitcoin last year produced emissions responsible for around 19, future deaths.
How Bitcoin's electricity usage compares with selected countries. The data in a blockchain has no inherent meaning. Its sole purpose is to record difficult, but pointless, calculations which provide a basis for allocating new crypto coins. Cryptocurrency advocates have given a variety of excuses for the monstrous energy consumption, but none stand up to scrutiny.
Some, for example, seek to justify cryptocurrency's carbon footprint by saying some miners use renewable energy. That may be true, but in doing so they can displace other potential energy users — some of whom will have to use coal- or gas-fired power. But now, the most successful of Bitcoin's rivals, Ethereum, is changing tack. This month it promises to switch its computing technology to something far less polluting.
