Many of the industry’s leading currencies use a protocol known as proof-of-work (PoW) in order to carry out transactions securely, without relying on middlemen like banks. Since its inception, PoW has been the model behind Ethereum, but many of the platform’s leading figures want this to change. PoW can be thought of as a governance model that both incentivizes users to partake in maintaining the integrity of the network, and treats all users as equal.Įffectively, this a peer-to-peer system where transactions can occur without requiring verification from any outside source, which is why it’s often called a “trustless” payments platform. When a transaction is sent, a verification process enlists the help of network-connected devices. ETHEREUM CRYPTOCURRENCY JETTISON SPEEDIER PROOFOFSTAKE VERIFICATION These devices are operated by users that volunteer to temporarily donate their computer’s resources for the purpose of verifying transactions. These users are known as ‘miners,’ and their computers race to solve complex mathematical equations. These miners can then earn the transaction fee as a reward for their participation. Why scaling is a major issue for many cryptocurrencies Proponents of proof-of-work site numerous benefits with the protocol, such as its commitment to treating all miners as equal and its heightened level of security. However, currencies that employ PoW like Bitcoin and Ethereum face severe hurdles in achieving adoption.

Economic disincentives have been put in place to dissuade behavior that is bad for the network. 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. 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. 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… It’s thought that switching to proof of stake would cuts Ethereum’s energy use, estimated at 45,000 gigawatt hours by 99.9%. 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.
