Interesting (unfortunate?) time to launch this with the malleability attacks going on.

  Is this a dank meme based on the fall of mtgox or are there actually malleability attacks going on?

    The Bitcoin network is presently undergoing a malleability attack designed to cause Bitcoin nodes to run out of memory. http://motherboard.vice.com/read/i-broke-bitcoin http://motherboard.vice.com/read/i-broke-bitcoin

      Not quite; there are two separate attacks currently ongoing against Bitcoin: * The malleability attack: a transaction relayer is able to change the hash of the transactions, thus confusing senders or receivers who rely on this hash to check if the transaction has confirmed. This creates a nuisance, but all money arrive where they are supposed to. This attack does not affect memory usage on nodes, and it's an old and well-known issue. * A transaction spam attack (misleadingly called a "stress test") where a shady group called coinwallet.eu creates a large amount of big transactions. These mostly have appopriate fees so that regular users who want their transactions to confirm in a timely manner has to out-bid the spammer. All the unconfirmed transactions are stored in the memory of nodes, so this severely affects memory usage (currently about 1 GB on some nodes).

        Why do you say it's misleadingly called a stress test? Regardless of motives it is effectively stressing the bitcoin network AFAIK.

          "stress testing" and "maliciously stressing" aren't the same, motive is inherent in the word "test"

          It's stressing the network, but it's not a test - it's an attack.

        The distinction between "stress test", "spam attack", and "actual use" is kind of academic as long as the network can't handle either.
