Under the PoW mechanism, miners compete to solve complex mathematical problems. PoW is the original consensus mechanism for verifying transactions that bitcoin used. Both are essentially different algorithms that allow users to add transactions and record them on a blockchain, an immutable public ledger.īefore the Merge, you had to go through the energy-intensive process known as proof-of-work (PoW) to create Ethereum tokens. This is why many cryptos either use proof-of-stake or proof-of-work to validate crypto transactions. Cryptocurrencies are decentralized, meaning they don’t have the control of a financial institution to verify transactions. The proof-of-stake concept is fairly technical, and we did our best to break it down in a previous post here. However, lower fees haven’t come into effect on the Ethereum network yet. The merger should make it easier to introduce upgrades to the network in the future. This merger is positive news for those who are socially conscientious investors because of the significant decrease in energy consumption. On September 15, 2022, the original Ethereum Mainnet merged with the Beacon Chain to exist as one chain. On December 1, 2020, Ethereum launched a separate proof-of-stake Beacon chain. The Ethereum Foundation has claimed that the transition reduced Ethereum’s energy consumption by 99.95%. Ethereum decided to shift from the energy-intensive proof-of-work to the more environmentally friendly proof-of-stake system. The major issue with mining crypto is the amount of energy required to verify transactions on blockchains that require proof of work. The White House administration has gone as far as to float the idea of exploring possible options to limit energy-intensive mining, like bitcoin, if the process doesn’t become greener. With the government in China cracking down on crypto mining, the U.S. The White House has been calling for crypto mining standards to reduce energy usage. A major criticism of cryptocurrency is that it has a negative impact on the environment.
