Make at home mackerel!Ethereum 2.0 Testnet Validator node (Prysm version) -How to manage and management to prevent the decrease in assets?

　I am interested in crypto assets (cryptocurrencies), but I can't go by investing.If you think so, why not start by actually moving your hands and touching the technology of encrypted assets?

　In particular, for those who are interested in server management and network monitoring, it is a very challenging and attractive story that can operate blockchain networks at home.

　For example, Ethereum (Ethereum) launched a large -scale update phase (phase 0) of a large -scale update called Ethereum 2.0 at the end of 2020, and the consensus mechanism of the blockchain from the conventional "POW (Proof of Work)".(Proof of Stake) has started switching to "".

　As a result, if you leave 32Eth for about two years, anyone can participate in the network as "Validator" in Ethereum 2.0, and approve blocks under the computing resources of realistic performance.Can do.

　In the conventional Pow, mining requires high computing power, but in POS, there is no need to compete so -called calculation because randomly selected users from Validator approve blocks.In other words, you can participate in the blockchain network without preparing expensive graphic cards.

　Of course, at the moment, when the price of cryptographic assets continues (April 2021), the threshold has become extremely high at the time of "leaving 32ETH (7 million yen or more)", but what is the production environment?By using another Testnet, you can experience the Ethereum 2.0 world as Validator, without such expenses (of course, the reward is not worthwhile).
