Has anyone tried analyzing the actual blockchain for likely malleated (malled?) transactions? Depending on which form of malleability was exploited (see: https://gist.github.com/sipa/8907691 https://gist.github.com/sipa/8907691) it should be fairly easy to separate "normal" transactions generated by "normal" clients and intentionally malleated transactions.
- fsckin 13y agoThe past tense is "malleableized".
- pygy_ 13y ago"Modified"?
- 001sky 13y agoMalleable is a descriptive adjective (not a verb)[1] Malleability is a property-noun (also not a verb)[2] These words do not have "past-tenses" [1] http://www.oxforddictionaries.com/us/definition/american_english/malleable http://www.oxforddictionaries.com/us/definition/american_eng...

- gojomo 13y agoThe verb malleate (shape with a hammer), related to the adjective malleable (able to be shaped as with a hammer), has the past tense malleated (as grandparent comment properly intuits). http://en.wiktionary.org/wiki/malleate#Verb http://en.wiktionary.org/wiki/malleate#Verb
- dredmorbius 13y agoFYI, GCIDE lists "malleate" citing 1913 webster as a transitive verb: Malleate \Mal"le*ate\, v. t. [imp. & p. p. {Malleated}; p. pr. & vb. n. {Malleating}.] [L. malleatus hammered, fr. malleus a hammer. See {Mall}, v. t.] To hammer; to beat into a plate or leaf. [1913 Webster]
- 001sky 13y agoA transaction is not "malleable" in the hammer-hitting sense. It is only "malleable" in the abstract sense (of pliable). It makes more (common usage) sense to "exploit the transactions malleability" (pliability) than to say the transaction was "malleated" (ie, hit by a hammer). That's all I was trying to point out.
- dredmorbius 13y agoGiven that "malleable"'s meaning has evolved from the same root, you're being pedantic.
- wyager 13y agoI've seen a lot of people using "mutated". There is not a good verbification of "malleable".
- PhasmaFelis 13y agoDoesn't "malleable" literally mean something like "shapeable with a hammer," from the Latin malleus, "hammer"? Maybe the verb form should be "hammered."
- scrollaway 13y agoI am a little more inclined to believe MtGox being hammered had something to do with this fiasco.
- dredmorbius 13y agoDrunk on the Kool Aid....
- gjm11 13y agoThere's "malleate", which really truly does go with "malleable". But it has only the original literal meaning of "beat into shape with a hammer" and not the generalized meaning implicit in "malleable".
- StavrosK 13y agoEh, we can change that.
- maaku 13y ago"Mutated." "Malleability" is the property of transactions that aspects of their serialization format can be changed without invalidating them. Actually changing transactions is called "mutation", the past tense of which is "mutated".
- carbocation 13y ago"Mutability" would make sense in that context rather than "malleability", no?
- maaku 13y agoYes, but "malleability" is the established word in the technical literature.
- olalonde 13y agoYes it would be possible to detect "malleated" transactions with high confidence for certain classes of malleability[0]. I'm not aware of anyone having done such analysis yet. [0] The types of transactions that are less likely to catch false positives would probably be those that have "superfluous scriptSig operations". For other classes of malleability, it would be more difficult to tell whether a given transaction was the result of a malleability attack or if it was just a transaction produced by an alternative client.
