[Cryptography] Schneier in Wired: There's No Good Reason to Trust Blockchain Technology Crypto
Nothing particularly new here, just reminding us why whatever problems public blockchains solve, they are not problems you have. https://www.wired.com/story/theres-no-good-reason-to-trust-blockchain-technology/ Regards, John Levine, johnl@iecc.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly h/t to Dave Farber's IP list _______________________________________________ The cryptography mailing list cryptography@metzdowd.com http://www.metzdowd.com/mailman/listinfo/cryptography

Yup, and it points out an important feature about trust in conventional financial mechanisms: If something goes wrong with a conventional mechanism, I trust that the bank or credit card company, or ultimately the courts and/or government regulators, will sort it out. That's worked for centuries. The blockchain on the other hand is the car without seatbelts and brakes of the financial system. If something goes wrong with a blockchain-based mechanism, I trust that I'm screwed. Enthusiasm for blockchain seems to follow a pattern of being inversely proportional to the enthusiasts knowledge of how large-scale financial systems work (with the occasional exception of people who are aware of how they work but have thrown in the blockchain because it'll get then funding).

We've seen that in ETH network e.g. with DAO Hack [1] and in fact discussions about altering part of the chain still happens from time to time. So yeah, no court or formal institution can decide here but vote of majority of the hosts (users). I believe for some minds especially those with a bit anarchistic inclination such model can be appealing. For general public though? Well, let's face it - cryptocurrencies never got to the point where they're used by general public anyway.

At this point, the main concern I have related to these schemes is that they mustn't be allowed to pull the whole field down with them when they go down the plughole. It is impossible to have a serious discussion with a group of people who are convinced that they are exceedingly clever and are part of a small select group that has found a way to make a fortune by virtue of their being so very very very very clever. It was the same with the 'High Income Yield' scams (or whatever they were called). It isn't an accident that Bitcoin started its rise six months before Liberty Reserve was raided. The whole Bitcoin system is a lab experiment that escaped. It takes the 'credit' for every success while disowning every failure and problem identified as being a result of the immaturity of the system. The biggest conceit is that they have eliminated fraud. Which they have done by defining all fraud to be the fault of the user and therefore not a problem of the system. Another conceit is that their system is sound unless someone can prove that it isn't. That is the wrong standard. Banks have compliance departments that are based on the assumption that nothing is legitimate unless it can pass an audit. Bitfinex have been promising an audit of Tether for years now, it has never happened and anyone looking at how the BitCoin price miraculously recovers after a dip knows it never will. I don't believe BitCoin is worth $3,500. It is only worth 3,500 tethers and nobody really knows how many of those can be redeemed at par before the founders do a Quadriga. They may be running an honest operation but they don't feel the need to demonstrate this. If someone tells me that I can become exceedingly rich if I just let them hold my money for me for a little while, I start with the assumption they are going to cheat me. And of course, absolutely none of these issues have anything to do with the cryptography. Which is important to keep pointing out because when these Ponzi prats all start dropping off window ledges, mainstream media is going to be asking why we never warned them. And of course most of us did and we were ignored. All in all BitCoin is just a more sophisticated Nigerian prince scheme. Only instead of making the money moving the gold out of Nigeria or removing diepack off dollar bills, the marks are supposed to double their money in a month 'investing' in BitCoins and instead of the scammers making their money by asking for advance fees, they persuade the 'investors' to let them hold their stake for them. _______________________________________________ The cryptography mailing list cryptography@metzdowd.com http://www.metzdowd.com/mailman/listinfo/cryptography

Three of these four purchases were the use of bitcoin to get around political censorship and political repression. _______________________________________________ The cryptography mailing list cryptography@metzdowd.com http://www.metzdowd.com/mailman/listinfo/cryptography
