Proof of stake, which is already used by other blockchains, can drastically reduce the amount of energy used by having miners lock up crypto they already own as collateral for the chance to validate transactions and face the penalty of losing those tokens if their calculations don’t add up. Computers around the world connect to validate the transactions, solving cryptographic puzzles in a competition to mine blocks and earn valuable crypto for the people who operate them. There have been tests and shadow forks to try and identify potential issues already, and a now-completed merge with the final testnet, Goerli, has gone well enough to help narrow down a date for the actual live network.īitcoin and Ethereum currently both rely on proof-of-work systems to execute secure transactions that enable cryptocurrency trading and everything else that lives on the blockchain. This would change the system that underpins the Ether cryptocurrency that is second only to Bitcoin in value as well as a number of other blockchains and distributed apps that connect to the network in various ways. The article also argues that Bitcoin's 'growing dominance by huge, centralized mining farms' is 'antithetical to a system that was designed to be decentralized.58750000000000000000000- Tim Beiko | timbeiko.eth August 11, 2022

On that day, only the test network will get an update, while the main cryptocurrency network will get it sometime in the near future. And now, on June 8th, Ethereum’s test network called Ropsten will host the merge to shift to staking and abandon mining completely. Economic disincentives have been put in place to dissuade behavior that is bad for the network. Years ago, Ethereum developers decided to quit cryptocurrency mining. In a proof of stake system, it would be harder than in a proof of work system for a group to gain control of the process, but it would still be possible: The more Ether a person or group stakes, the better the chance of being chosen as a validator or attestor. With sharding, Vitalik Buterin, the inventor of Ethereum, thinks that could go to 100,000 per second. Currently, Ethereum handles about 30 transactions per second. Ethereum, launched in 2015 by a 21-year-old whiz kid named Vitalik Buterin, is about to swap proof-of-work mining for an alternative system known as proof of stake, which does not require energy. That's important for Ethereum, which has ambitions of becoming a platform for a vast range of financial and commercial transactions. It also is expected to increase the network speed. Like any other venture depending on cloud computing, its carbon footprint would then be only be that of its servers. It's thought that switching to proof of stake would cuts Ethereum's energy use, estimated at 45,000 gigawatt hours by 99.9%.

The idea behind proof of stake is that the blockchain can be secured more simply if you give a group of people carrot-and-stick incentives to collaborate in checking and crosschecking transactions. Along with being greener and faster, proponents say the switch, now planned to be phased in by early 2022, will illustrate another difference between Ethereum and Bitcoin: A willingness to change, and to see the network as a product of community as much as code. It was pioneered by Bitcoin and adopted by Ethereum, and has come under increasing criticism for its environmental impact: Bitcoin miners now use as much electricity as some small nations. Miners are the heart of a system known as proof of work. 'Perhaps the most important is the jettisoning of the 'miners' who track and validate transactions on the the world's most-used blockchain network. 'Ethereum is making big changes,' writes Bloomberg.
