The only super broken thing (as far as I can tell) is that the designers for some reason decided to use txid for the spending of unconfirmed outputs. For exchanges this isn't really a problem, a possible solution is posted in the other thread (per block settlement tx) and look for immutable things in txs that are included in subsequent blocks. The ECDSA signatures generated will always be random because of the specifications, but pubkeys and their hashes (addresses) and the values of inputs/outputs are always immutable for any given tx.
As far as I can tell, generating immutable txid actually isn't that hard -- there are a bunch of immutable things in any transaction you can choose to hash instead of mutable things like ECDSA signatures.
This isn't a problem for most of the large exchangers anyway, as they're not using bitcoind in the first place as it's poorly scalable and recognized the problem that malleability posed long before.
Topic: A quick fix for the current issue vrs the right fix (Read 702 times)
Guys, honestly, we need to all stop fixating on little b here... This isn't a little b problem. The problem is a big B problem and it makes all the sense in the world for the devs to take the time they need to patch this problem. They have know they would have to for a long time, but since there is no existential threat to the big B here. The attacks are not going to cause a fork in the blockchain, and they don't make it possible for someone to steal you coins. That is the main reason it hasn't been addressed until now. They/We have know this could happen but there isn't too much economic incentive for someone to try this attack unless they are trying to kill competitors, weaken little b to get in lower, or are just bored and malicious.
There isn't a need for an immediate bandaid. All of you that are afraid of people "losing faith" are talking about the price of your current little b investments. Bitcoin, big B bitcoin, isn't about the value of little b bitcoins. It's the ledger and the network that matter, ultimately. At some point the price of bitcoins could conceivably be almost zero or many geometric iterations higher then it is now... none of that will effect the real value here which is clearly, "Big B".
They will get this problem fixed, but for now, realize, its more of an annoyance then anything. For those stuck with money at gox, or who have lost money somehow in this mess, obviously the problem is much bigger for you, and I offer my sincere apologizes if my little rant here is insensitive to your personal plight. I am talking more holistically and about the framework. I guess I just wanted to say something because I am hearing people that the end is nigh, really, imo, because they are worried as they see value of their bitcoins falling.
