Ethereum advocate Jim McDonald, general manager of Weald Technology, is trying to predict the cost of future Ethereum 2.0 validators. McDonald mentions three main types of validator costs: setup, infrastructure, and operating expenses. The first type of cost includes the cost of selecting hardware, operating system, and software implementation. The last one seems to be the most difficult because there are currently six Ethereum network implementations available.
Infrastructure costs include depreciation of hardware, power, and network costs. McDonald suggested that it would be best to calculate a 36-month depreciation period. Operating costs include costs for maintaining hardware, software upgrades, and reassessment implementations. But the most interesting statement made by McDonald is that with the development of the Ethereum 2.0 network phase, its costs will increase significantly, including Phase 1 and Phase 2. It should be pointed out that McDonald failed to use specific figures to explain the approximate cost. According to the latest estimates, the minimum collateral required for Ethereum 2.0 is 32 ETH, with an annual expected yield of 4-5%.
