Sorry but this comic is neither simple nor accurate.<p>Firstly, recording the account of sahti is the only function of the ledger, which supposedly is a subset of a record of everyone's deeds' including the elves. Secondly then, fee analysis has shown that blockchains are a poor store of data and should not be used as a database since other mechanisms are far more efficient and cheaper.
For anyone that's curious, the first set of runes is Futhark, and transliterate to:<p>>"That is not dead which can eternal lie. And with strange aeons even death may die"<p>The second and third are Enochian and transliterate to:<p>>"There is no sanity clause" and "Madness is the emergency exit"<p>respectively.
I guess the purpose is satirical, but it's an awfully complicated explanation. I guess it can be understood only by people who already know how a blockchain works.
If you struggled with this explanation then I can try another a bit more IT related.<p>A blockchain is...<p>A distributed fault tolerant public database that no one owns and everyone can update.<p>Has this been done before?<p>Kind of, distributed database are not new. What is new is solving the problem of multiple updates changing the same data at the same time.<p>So for example let's say the following happens to our distributed database.<p>User 1 send the following SQL to the network.<p><pre><code> Update customer set balance = 1000 where name = 'Customer1'
</code></pre>
and User 2 at the exact same time tries<p><pre><code> Update customer set balance = 2000 where name = 'Customer1'
</code></pre>
A blockchain database will have both statements in a block and execute them on every node in the same order. Other distributed databases would run into race conditions.<p>So when you hear the statement<p><i>Blockchain startup X is going to disrupt industry Y.</i><p>You can reorganize the statement into something like.<p><i>Startup X is going to disrupt industry Y with a new type of distributed database.</i>
We build a web application for companies to keep track of their CO2 Emissions and some other key performance indicators and assessments. Yesterday our boss called one of my colleagues and said:<p>"A customer of ours suggested that we use blockchains to improve the security of our application. What do you guys think?"<p>It is probably the equivalent of saying you use scrum and are oh so very agile. "We use blockchains for added security". What this would look like is then left up to the imagination of the person confronted with this phrase.<p>[1]: <a href="http://www.csoonline.com/article/3050557/security/is-the-blockchain-good-for-security.html" rel="nofollow">http://www.csoonline.com/article/3050557/security/is-the-blo...</a>
I could be wrong, but I'm pretty sure this wasn't made in MS Paint. All the edges of the shapes look way too anti-aliasied.<p>Looks more like something made with paint.NET.<p>(I have never used the MS paint version that comes with win10, so maybe they improved it a lot)
I'm not convinced by this format. I think the whole information would have been easier to digest, if it was presented in a clear and concise format, without any unnecessary detours and metaphors.
