To run Ethereum effectively, you need a dedicated computer with sufficient capabilities, an always-on power supply, and an internet connection. Additionally, you require a substantial amount of Ethereum at least 32 ETH (currently valued at around $75k), which presents a significant barrier to entry. The future looks even more challenging, with protocol upgrades likely increasing node requirements and Ethereum prices potentially rising further. However, there's optimism due to developments like Distributed Validator Technology (DVT), which promises to revolutionize Ethereum's decentralization by facilitating distributed validation. Brett Li, Chief Growth Officer at Obol Labs, discusses DVT's significance, highlighting its potential to address concerns and advance Ethereum's evolution into a modular blockchain paradigm.
