    Now if the majority, but not all have the backdoor, then the longest branch will not make sense to the minority. So even though the backdoor branch is the longest, the non-backdoor implementations will not add to it. That means there will be a very noticeable fork in the blockchain.

    A very noticeable backdoor is easily fixed.

    If there is a backdoor that the majority wants to keep, then the minority can simply fork the blockchain and continue on without the backdoor.

    Blockchains are a way of establishing consensus without any form of centralized control.
    nobody cares about your short branch.

    the fact remains.... different implementations can have different backdoors.

    you're still saying dumb shit.

    so... the everyday non programmer joe user must decide which blockchain gang they're in?

    ridiculous bullshit.

    How secure is blockchain really?
    It turns out “secure” is a funny word to pin down.
    By Mike Orcuttarchive page
    April 25, 2018

    .....

    Creative ways to cheat
    So much for the theory. Implementing it in practice is harder. The mere fact that a system works like Bitcoin—as many cryptocurrencies do—doesn’t mean it’s just as secure. Even when developers use tried-and-true cryptographic tools, it is easy to accidentally put them together in ways that are not secure, says Neha Narula, director of MIT’s Digital Currency Initiative. Bitcoin has been around the longest, so it’s the most thoroughly battle-tested.

    People have also found creative ways to cheat. Emin GŁn Sirer and his colleagues at Cornell University have shown that there is a way to subvert a blockchain even if you have less than half the mining power of the other miners. The details are somewhat technical, but essentially a “selfish miner” can gain an unfair advantage by fooling other nodes into wasting time on already-solved crypto-puzzles.

    Another possibility is an “eclipse attack.” Nodes on the blockchain must remain in constant communication in order to compare data. An attacker who manages to take control of one node’s communications and fool it into accepting false data that appears to come from the rest of the network can trick it into wasting resources or confirming fake transactions.

    Finally, no matter how tamperproof a blockchain protocol is, it “does not exist in a vacuum,” says Sirer. The cryptocurrency hacks driving recent headlines are usually failures at places where blockchain systems connect with the real world—for example, in software clients and third-party applications.

    Hackers can, for instance, break into “hot wallets,” internet-connected applications for storing the private cryptographic keys that anyone who owns cryptocurrency requires in order to spend it. Wallets owned by online cryptocurrency exchanges have become prime targets. Many exchanges claim they keep most of their users’ money in “cold” hardware wallets—storage devices disconnected from the internet. But as the January heist of more than $500 million worth of cryptocurrency from the Japan-based exchange Coincheck showed, that’s not always the case.

    Perhaps the most complicated touchpoints between blockchains and the real world are “smart contracts,” which are computer programs stored in certain kinds of blockchain that can automate transactions. In 2016, hackers exploited an unforeseen quirk in a smart contract written on Ethereum’s blockchain to steal 3.6 million ether, worth around $80 million at the time, from the Decentralized Autonomous Organization (DAO), a new kind of blockchain-based investment fund.

    Since the DAO code lived on the blockchain, the Ethereum community had to push a controversial software upgrade called a “hard fork” to get the money back—essentially creating a new version of history in which the money was never stolen. Researchers are still developing methods for ensuring that smart contracts won’t malfunction.

    The centralization question

    One supposed security guarantee of a blockchain system is “decentralization.” If copies of the blockchain are kept on a large and widely distributed network of nodes, there’s no one weak point to attack, and it’s hard for anyone to build up enough computing power to subvert the network. But recent work by Sirer and colleagues shows that neither Bitcoin nor Ethereum is as decentralized as you might think. They found that the top four bitcoin-mining operations had more than 53 percent of the system’s average mining capacity per week. By the same measure, three Ethereum miners accounted for 61 percent.

    Some say alternative consensus protocols, perhaps ones that don’t rely on mining, could be more secure. But this hypothesis hasn’t been tested at a large scale, and new protocols would likely have their own security problems.

    Others see potential in blockchains that require permission to join, unlike in Bitcoin’s case, where anyone who downloads the software can join the network. Such systems are anathema to the anti-hierarchical ethos of cryptocurrencies, but the approach appeals to financial and other institutions looking to exploit the advantages of a shared cryptographic database.

    Permissioned systems, however, raise their own questions. Who has the authority to grant permission? How will the system ensure that the validators are who they say they are? A permissioned system may make its owners feel more secure, but it really just gives them more control, which means they can make changes whether or not other network participants agree—something true believers would see as violating the very idea of blockchain.

    So in the end, “secure” ends up being very hard to define in the context of blockchains. Secure from whom? Secure for what? “It depends on your perspective,” says Narula.

    Look, the Military Industrial Complex - which I worked in for 35 years - is problematic. The L1's bribe elected officials and procurement personnel in the military as a matter of standard procedure.

    Oh, it's not usually cash or anything so blatant - but notice how those who purchase systems within the military "retire" after 20 years into cushy jobs at the primes.

    I'm fully aware of the graft and sleaziness. But set policy? You're nuts. The L1's are all about getting funding for programs. It's business - often shady - but Raytheon doesn't set agendas, they sell weapon systems. They might do favors for Senators to ensure PAC-3 is chosen over what Lockheed is offering, offering cushy jobs to relatives and associates.

    It's not a fantasy, fucktoid. citizens united made unlimitd corporate giving a reality.

    it's not even crony capitalism because it's TOTALLY LEGAL.

    that's why it's textbook fascism.


    quit insulting us with your idiotic word games.

    stop being a deep state traitor please.

    do better.

    That is a leftist urban legend with zero truth.

    Citizens United protected the right of free speech for all Americans. democrats had outlawed media critical of the party. Notice that "Fahrenheit 9-11" was just fine - only "Hillary the Movie" was outlawed.

    THAT is fascism.

    There are stringent limits on both direct donations by PAC's and in kind contributions.

    Conspiracy theory idiocy. You refuse to learn even as I've explained what the collectivist totalitarian system known as "Fascism" is.

    You are obviously a leftist trying to defame the right with this moronic shit.

    no.

    it's unlimited corporate giving in actuality.

    your whole 'corporations are people' shtick is wearing thin, libertarian fascist anti-human.


    With its decision, the Supreme Court overturned election spending restrictions that date back more than 100 years. Previously, the court had upheld certain spending restrictions, arguing that the government had a role in preventing corruption. But in Citizens United, a bare majority of the justices held that “independent political spending” did not present a substantive threat of corruption, provided it was not coordinated with a candidate’s campaign.

    As a result, corporations can now spend unlimited funds on campaign advertising if they are not formally “coordinating” with a candidate or political party.

    How has Citizens United changed elections in the United States?
    The ruling has ushered in massive increases in political spending from outside groups, dramatically expanding the already outsized political influence of wealthy donors, corporations, and special interest groups.

    ROFL

    So you claim CU established that "corporations are people", right?

    Complete bullshit.

    CU discarded provisions of the McCain-Feingold act that limited media production by Political Action Committees.

    Ohh, the Brennan Center.

    I guess you've shed your pretense of being a conservative.

    I assume you'll post from DailyKOS and Alternet next.

    it allowed unlimited corporate ad spend.

    the fascism is also the revolving door between elected office and large corporations and banks. the cheney and the haliburton and the bushes and the carlyle and the bin ladens.

    the insider trading is also the fascism.

    i love watching fascists squirm in their lies.
