That may be a superb query. I used to be truly a proof-of-work maximalist earlier than designing the spiderchain, however I noticed {that a} proof-of-work on a second layer truly does not make a whole lot of sense. So, I regarded into proof-of-stake and browse all of the completely different white papers. In 2022, when Ethereum merged to proof-of-stake, there have been a whole lot of Bitcoiners, together with Jack Dorsey, who have been retweeting this article about why proof of stake is insecure. So, I learn the article. Every of the arguments in it have been truly solved in the event you construct with proof-of-stake on a second layer. Let me go rapidly over the arguments. Primary is the financial argument. Proof-of-work is a leaking system and proof-of-stake is a closed system. That implies that proof-of-work has a decentralizing pattern. You have to pay for the electrical energy, so worth leaks out of the system. Bitcoin, over time, turns into increasingly more decentralized, as a result of that worth leaks out into the actual world. Proof-of-stake is the other. It truly has a centralizing pattern. The stakers get an even bigger and larger portion of the overall 100% share of the belongings over time. As a layer one, as a forex, that does not make a whole lot of sense.
