The threat model and legal questions of smart contracts are another huge deterrent for most businesses.&lt;p&gt;Latency, throughput, security threats, and cost are all fairly understood with normal databases, yet with blockchain software all of these are measurably worse.&lt;p&gt;Where are the completed successful smart contracts deployed?&lt;p&gt;Why would any person or business want&amp;#x2F;need to use an existing blockchain when some bug or mining operator might cause a catastrophe of that system, who would they sue for damages?&lt;p&gt;A single user who spent less than $5000 crashed the entire market for Ethereum last summer. Most of the supply of ETH, XMR, BTC and other crypto tokens are owned by a very small population of crypto-oligarchs.&lt;p&gt;It all seems like a marketing scheme to sell cyber beanie babies to people who are unfamiliar with the engineering flaws in distributing computing and the marketing lies from “investors” who need to pump the price on their magic beans.</text><parent_chain><item><author>seibelj</author><text>Cryptocurrencies, and especially Ethereum, are truly novel innovations in computer science that cross many academic disciplines.
