The Blockchain Has Only Ever Been A Pimper's Paradise...,

thecorrespondent  |  It seems that blockchain sounds best in a PowerPoint slide. Most blockchain projects don’t make it past a press release, an inventory by Bloomberg showed. The Honduran land registry was going to use blockchain. That plan has been shelved. The Nasdaq was also going to do something with blockchain. Not happening. The Dutch Central Bank then? Nope. Out of over 86,000 blockchain projects that had been launched, 92% had been abandoned by the end of 2017, according to consultancy firm Deloitte.  

Why are they deciding to stop? Enlightened – and thus former – blockchain developer Mark van Cuijk explained: “You could also use a forklift to put a six-pack of beer on your kitchen counter. But it’s just not very efficient.”

I’ll list a few of the problems. Firstly: the technology is at loggerheads with European privacy legislation, specifically the right to be forgotten. Once something is in the blockchain, it cannot be removed. For instance, hundreds of links to child abuse material and revenge porn were placed in the bitcoin blockchain by malicious users.

It’s impossible to remove those.

Also, in a blockchain you aren’t anonymous, but “pseudonymous”: your identity is linked to a number, and if someone can link your name to that number, you’re screwed. Everything you got up to on that blockchain is visible to everyone.

The presumed hackers of Hillary Clinton’s email were caught, for instance, because their identity could be linked to bitcoin transactions. A number of researchers from Qatar University were able to ascertain the identities of tens of thousands of bitcoin users fairly easily through social networking sites.
Other researchers showed how you can de-anonymise many more people through trackers on shopping websites.

The fact that no one is in charge and nothing can be modified also means that mistakes cannot be corrected. A bank can reverse a payment request. This is impossible for bitcoin and other cryptocurrencies. So anything that has been stolen will stay stolen. There is a continuous stream of hackers targeting bitcoin exchanges and users, and fraudsters launching investment vehicles that are in fact pyramid schemes. According to estimates, nearly 15% of all bitcoin has been stolen at some point.
And it isn’t even 10 years old yet.
