mempool is memory limited now, so no one cares about mempool spam anymore.

ok, I'm just hearing a bunch of stuff from people using bitfinex that they can't make transactions happen based on the blockchain itself
17:13
<

if you're not seeing anything anomalous then it's just people not putting enough fees...
17:13
<
gmaxwell >
cjd: or they're rate limiting withdrawls?

*basically they have transactions hitting the mempool but not getting mined

"Can bits of an RSA public key leak information about design and implementation choices such as the prime generation algorithm? We analysed over 60 million freshly generated key pairs from 22 open- and closedsource libraries and from 16 different smartcards, revealing significant leakage. The bias introduced by different choices is sufficiently large to classify a probable library or smartcard with high accuracy based only on the ...

... values of public keys. Such a classification can be used to decrease the anonymity set of users of anonymous mailers or operators of linked Tor hidden services, to quickly detect keys from the same vulnerable library or to verify a claim of use of secure hardware by a remote party.

as a black box construction it shouldn't matter the relationship between the two generators in an EC pederson commitment scheme, so long as DLP of one is not known with respect to the other, but i'm sure that there must exist mutually weak points

(as there are weak curves for various types of attack)

what are weak points?

unsure, i just have a feeling that any point cannot be equally secure as a second generator

all generators are equal in curves like secp256k1.

Imagine if you have alternative generator Q where discrete log wrt Q is somehow easy. Now you find the DL of G with respect to Q... then you can transfer problem of finding P wrt G by multiplying P by the ratio of the two generators to make it problem of finding the DL of some other point with respect to Q.

gmaxwell: you mean "all points are generators" - any generator is by definition as good as any other generator, but there are curves which have points that are not generators

hardness uniform throughout the group because it's multiplicatively constant

can we not use Schnorr authentication and godel numbering to do arbitrary expressions in zero knowledge?
22:45
<
nsh >
really you want to prove that you know something that matches an arbitrary expression, which is another thing to proving you can formulate an arbitrary expression
22:45

godel numbering doesn't preserve the semantics of the language
22:46
<

doesn't necessarily. you can apply certain prescriptive numberings that preserve some properties

feel free to try

well mapping numbers to points by x → xG preserves addition. but not multiplication. you'd need to do both at once somehow
22:47
<
andytoshi >
and given that your group only has one operation..
22:47
<

and any other operations the expression language has

i think polynomial circuits are fully general, if you can add and multiply you can do small programs at least

speak of that, anyone knows in general how difficult is the subgroup membership problem? like comparing to DLP?
22:50
<
proslogion >
say i have a random number, i want to find out if it has a discrete log with generator g

proslogion: testing whether it belongs to a subgroup of a given size (or divisor thereof) is easy

sipa: with a particular generator?

if you know there is only one generator of a certain order it is easy :)
