The straw that broke the camel’s back: Google+ shuts down

Google’s relationship with social media has always been troubled. Widely believed to be aimed at attacking Facebook’s dominance in that domain, Google+ never quite lived up to that dream. The social network from the maker of otherwise extremely successful products never took off and instead turned into something of a punching bag for internet enthusiasts. On October, 8th the Wall Street Journal reported that in March Google had found a bug in its code, making user data marked private visible to connection and third parties. This was the final push, the firm needed. Hours after the WSJ-article, Google announced that it was taking down the social network.

The company has no evidence that the bug has been exploited and nobody really shared much on Google+ anyway. Therefore, Google’s response may seem very swift and sweeping. This, self-evidently, has everything to do with the massive trouble Facebook has found itself in with the Cambridge Analytica Scandal. Although the number of affected users – if there even are any – is two orders of magnitude smaller, similarities abound. Both involved accidentally making available private user data to third party apps and Google, too, only took action after the incident was made public. If axing its unpopular social network could limit the damage done to the reputation of an otherwise extremely successful firm, this may have seemed a small price to pay for Google’s executives.

Few tears will be shed about the disappearance of Google+. More worrying from the internet giants’ perspective is the ever larger public outcry that follows their missteps. This combined with the advent of the General Data Protection Regulation the EU enacted in May may demand a significant mindshift from the internet giants. From “move fast and break things” to “restraint and caution” is a big step.

The use of blockchain in layman’s terms

There is a lot of hype around blockchain. Many people believe that it will change the world, fewer people actually know what it for. In these 300 words I hope to give an outline of what it can and cannot do.

The main point of this post? A blockchain is a database. As such, it can no more revolutionize all things legal, promote democracy around the world and solve global warming than a database can. That being said, blockchain is a type of database with some interesting properties for specific purposes. This is because the database is decentralized.

The vast majority of databases are centralized. This means information is only stored in one place. When you start a website, your hosting provider gives you access to THE single database of your site. It stores your user accounts, content of your site etc. If your database was decentralized, there would exist multiple versions of your database on servers owned by people all over the globe you don’t necessarily know or trust (in contrast to, presumably, your hosting provider).

This raises an obvious question: if those versions differ, which one is ‘correct’? This is where blockchain comes in. This technique makes sure the different ‘versions’ of your database can continuously ‘vote’ and form consensus about the correct ‘version’. This ensures conformity of the different ‘versions’ of your database.

This technique may be useful because it leverages the ‘wisdom of the crowd’. One player (or ‘node’) in the system finds it extremely hard to game it, because the information can only be destroyed or altered by destroying or altering a majority of the ‘nodes’. When these are anonymous, run into thousands or millions and distributed all over the world such as with Bitcoin, that is infeasible. This explains why the most important use cases of cryptocurrencies are outside the confines of the law.

Self-evidently, a centralized database is way more convenient for the majority of applications. When I’m buying something (legal) online, I’ll take PayPal over Bitcoin any time of day and I’m sure many of you feel the same.

Finally, a tip in case you’re having trouble seeing beyond the hype. There is this nice Chrome extension that on any website replaces the word “blockchain” with “multiple copies of a giant Excel spreadsheet”. That might serve as a friendly reminder 🙂
