Security Breach Forces Bitcoin Bank Inputs.io To Halt Operations

New submitter BitVulture writes "The hardcore Bitcoin community is abuzz with news of the closure of Inputs.io, a supposedly secure online Bitcoin wallet, after an attack resulted in the loss of 4100 Bitcoins. A PGP-signed message at the home page of the now mostly non-operational site briefly explains the situation: 'Two hacks totalling about 4100 BTC have left Inputs.io unable to pay all user balances. The attacker compromised the hosting account through compromising email accounts (some very old, and without phone numbers attached, so it was easy to reset). The attacker was able to bypass 2FA due to a flaw on the server host side.' There's no word yet whether Inputs.io will eventually resume operations or whether the security breach will force the Bitcoin bank out of business."

That's why it's recommended to use wallet like blockchain.info where you hold the private key so they can't spent bitcoin for you. In some case where they must hold the key for you (exchange service for instance) most of their coin should be in cold storage / not allocate to direct individual. In another news, Bitcoin value is at all time high over $300.

      This is the thing about BitCoin I never understood. The proponents of BitCoin claim that it was untraceable, but all transactions are traceable by looking at who spent the coin and who owns it now, at least by their public key. This information is included in the data blob that IS the coin and lots of people have to observe the transaction before it becomes valid. You may not know who's key is who's, but you certainly can trace ownership of the BitCoin.

      So, you may not know who owns a single coin, but though simple observation of transactions and a bit of foot work you can easily piece together who's who and who's spending their coins on what. It becomes a data mining operation with a bit of detective work to trace where folks are converting traditional currency into and out of BitCoin. Which is totally different than trading say dollars in currency. You *might* be able to trace currency transactions though things like DNA traces left on the bills or serial numbers (if you know them), but if somebody passes a briefcase of money around, there will be no way to trace each transaction that might have taken place.

A dollar bill doesn't actually represent value; it represents debt, an IOU. A bank doesn't need to keep one physical dollar bill on hand for every dollar in its bank accounts; it only needs a fraction, because you don't expect 100% of your customers to come in on the same day to cash out. And thanks to the Federal Reserve system, there aren't even physical assets (like gold bars) of equal value to all the Federal Reserve notes in circulation. It's a bizarre system that only works as long as debt keeps circulating (buying and selling) and accumulating (loans with interest).

The private banking system evolved the system that the Fed later put in place on a more equitable basis (loaning to all banks instead of only to those that Morgan had a personal affinity for, for example). Elasticity was necessary for the banking system to function.

The Athenians didn't have a Federal Reserve or central bank, just a mint for the physical coins and some private bankers for the credit. That's all you need to get the "bizarre system" that keeps cropping up in history.

  17. Why this strange fixation on physical currency? by sirwired · · Score: 2

    Well, I agree with you on one point: Robbing a bank by walking into the lobby of your local branch is very romantic, but it's a horrible and dangerous way to steal money, and has lousy returns. I'd say we've long past the point where that was the best way to rob a bank. (I'd say owning or running a bank is probably the best way to rob it...)

    A bank doesn't need to keep ANY dollar bills on hand for dollars in their bank accounts; only branch banks need physical currency at all. There are plenty of non-branch banks out there that don't have any physical currency; what would they need it for? The Fed does not require any bank, even Federal Reserve members, to hold any particular portion of their assets in currency (although I do think Federal Reserve members do need to let their account holders withdraw their deposits as cash at any point; it's how the Fed actually distributes cash out into the economy.)

    A dollar bill doesn't represent "debt"; it represents one dollar's worth of the world's total supply of dollars/dollar-denominated assets. In that sense, it's little different from a share of stock. Some of those dollar-denominated assets are debts, some are coins in my pocket, some are bits on my bank's hard disks, some consist of stacks of $100's in a cave in some benighted 3rd-world kleptocracy. If the supply of dollars increases faster than dollar-denominated assets, we have inflation, if the reverse happens, we have deflation.

    You may of course choose to blame the Federal Reserve for whatever you like, but the Fed did not create fractional reserve banking or fiat currency, nor did they originate the idea of moving money around through a method other sacks of cash.

    And even if we still had the gold standard, why would we tie the amount of gold on-hand to physical currency? Virtual currency is easier and safer to store, manage, and move. An electronic dollar is no different from a $1 bill in my pocket.

    BTW, yes, credit is the backbone of every modern economy in the world; this is hardly new... it's been the case for centuries. Modern capitalism would be utterly impossible without it.
