This article is bad. 1. The cost the mine a resource trends towards the value of the resource. As Bitcoin value goes up and down, hash rate tracks it going up and down. Increases in efficiency allow you to hash more at lower cost. However this is a red herring, as waste is required for POW, because: https://en.wikipedia.org/wiki/Signalling_theory https://en.wikipedia.org/wiki/Signalling_theory Thus, money wasted on hardware and electricity tracks Bitcoin price, and hash rate itself is a function of efficiency times energy waste while staying under BTC price profitability cap. 2. Most blockchains are empty, and they all work "decently." As decently as the worlds most expensive and slowest databases can be. What blockchains need is not higher TPS or lower fees, but more users. They say the demand for unlimited free storage is infinite, so a fee market must always exist, bounded by storage costs (and duplication across many nodes.) By the way, when I say most blockchains are empty, the amount of fee revenue generated per chain per day is PITIFUL and falls of amazingly fast. https://coinmetrics.io/charts/#assets=btc,bch_roll=7_left=FeeTotUSD_zoom=1279411200000,1584662400000 https://coinmetrics.io/charts/#assets=btc,bch_roll=7_left=Fe... says: BTC $342,000 in fees per day. ETH $95,000 in fees per day. BCH $130 in fees a day 3. 1000tps is already in production by zkrollups and optimistic rollups on ETH. See it in production at loopring.io. There's more BTC wrapped on ETH than in lightning on BTC. Disclaimer: I founded the #76 highest marketcap cryptocurrency, and one of its features is not paying miners block rewards, only fees. P.S. Scaling is cured enough for now using zkrollups. The market for slow, expensive databases should always be restricted to things that REQUIRE censorship resistance, and most things do not.
