Last month, Ethereum announced the postponement of the merge plan. At the Web3 event held this week, an Ethereum core developer said that the plan would be launched in August The plan is to switch from proof of work (POW) algorithm to proof of entitlement (POS), so that cryptocurrency uses less energy and does not need PC graphics card to mine.
Previously, Ethereum estimated that the merge plan would take place in June, but a developer confirmed last month that it had been postponed. Turning to proof of interest should be to solve some of the most important problems of cryptocurrency, reduce Ethereum's carbon footprint and alleviate miners' demand for uniqueness under proof of workload.
