Grin – A private and lightweight mimblewimble blockchain
Does Grin do something concrete and useful?<p>I ask this question because someone on HN reminded me of this great 2001 article from Joel &quot;Nostramdamus&quot; Spolsky on Blockchain Astronauts:<p>&gt; Don&#x27;t let Architecture Astronauts Scare You <a href="https:&#x2F;&#x2F;www.joelonsoftware.com&#x2F;2001&#x2F;04&#x2F;21&#x2F;dont-let-architecture-astronauts-scare-you&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.joelonsoftware.com&#x2F;2001&#x2F;04&#x2F;21&#x2F;dont-let-architect...</a><p>&gt; When you go too far up, abstraction-wise, you run out of oxygen. Sometimes smart thinkers just don’t know when to stop, and they create these absurd, all-encompassing, high-level pictures of the universe that are all good and fine, but don’t actually mean anything at all.<p>&gt; These are the people I call Architecture Astronauts<p>&gt; The Architecture Astronauts will say things like: “Can you imagine a program like Napster where you can download anything, not just songs?” Then they’ll build applications like Groove that they think are more general than Napster, but which seem to have neglected that wee little feature that lets you type the name of a song and then listen to it — the feature we wanted in the first place. Talk about missing the point. If Napster wasn’t peer-to-peer but it did let you type the name of a song and then listen to it, it would have been just as popular.<p>What&#x27;s the equivalent for Grin of &quot;that wee little feature that lets you type the name of a song and then listen to it&quot; ?
