@apoelstra wasn't expecting something as technical for an ibtimes article, but it's good!
@merope07 one thing money can't buy :-)

@apoelstra
heh, gmaxwell lent me a book "beggars in spain" about a girl who is genetically engineered to not need sleep, maybe one day money will be able to buy us that..
Ignotus Peverell
@ignopeverell
sleep feels pretty good tho :P

btw i'm working on secp schnorr code right now, so there is progress on that front finally. a few hours i did a MW-related talk in paris (nothing new, i was just presenting to get a flight to europe :)) and i think i'll stop doing that for a few months so i can do some real work
heh, yeah, and i do enjoy sleep. if only there wasn't always so much cool cypherpunk stuff to build :)
Ignotus Peverell
@ignopeverell
I was going to ask, that's great to hear (regarding Schnorr)
Europe is nice but not super cypherpunk for the most part...
Andrew Poelstra
@apoelstra
very true, i don't know that i'd enjoy living here. visiting is nice, they don't look twice at my canadian passport and i've never been hassled for my politics (tho i am much more conscious about what i post on public wifi networks than i am in the US..)

urza You should come to Prague to Parallel Polis when you are around :)
urza For example for the next hacker congress in October :) https://liberate.hcpp.cz/

urza If you would want to speak about MW/Grin I could arrange that

just lurking here, will hopefully be able to step in and help at some point
my focus in crypto coding these days is user experience so i would love to help on block explorer / wallet stuff
Ignotus Peverell
@ignopeverell
feel free to chime in anytime
and yes, help there would be great, for the explorer we're getting pretty close from an API standpoint I think
for the wallet I have some janky command line for developers for now
on the wallet side, as wallets need to be connected somehow, I was thinking of having a docker container that people can run on a couple cheap hosting services
that would run a pruning node with a little web wallet
and would have some sort of AWS-style machine DNS
people could just exchange the DNS for their servers and the wallets can connect and transact
from there, we could layer fun social interactions, with communication from one wallet to another, given that they'd be always running server
from a UX standpoint, new user could go to some site, say "I want a new wallet", pay some nominal monthly amount to have it run
Ignotus Peverell
@ignopeverell
then they only need other people's wallet addresses to start exchanging transactions
the private key can be stored encrypted on their servers and backed-up encrypted someplace with strong encryption
thought that'd be a nice mix of easy UX, running your own node while still having a simple web wallet, and decent security

@ignopeverell so mimblewimble is compatible with schnor sig?
Andrew Poelstra
@apoelstra
lukap3rcic: absolutely, it barely works without it
lukap3rcic: btw schnorr sigs on the kernels aren't really needed for multisig outputs, you can make multisig rangeproofs on the outputs and then they'll be unspendable except by multiple parties (this needs some dev work but no consensus changes)
lukap3rcic
@lukap3rcic
i taught MW it is ecdsa only, good to know
Andrew Poelstra
@apoelstra
heh, nooo
nothing is ECDSA only
lukap3rcic
@lukap3rcic
legacy standards are 🙈
Andrew Poelstra
@apoelstra
yuppers
lukap3rcic
@lukap3rcic
sorry to waste your time, but have to ask...
so schnorr would need a the consensus change right? Would/could ecdsa treshold signatures "of-chain" help here?
Andrew Poelstra
@apoelstra
there will never be a production ecdsa grin chain, so there's not really a consensus "change" needed..
but to answer your question, barely
they would be required to make mimblewimble usable at all without having as many kernels as participants in every transaction, and for valueshuffle to be possible
but requiring pallier encryption and associated security assumptions just to make transactions would be DOA
lukap3rcic
@lukap3rcic
oh, so the grin chain would support shnorr natively, gotch ya
(before it would be deployed for public)
Andrew Poelstra
@apoelstra
yes
lukap3rcic
@lukap3rcic
would bip32 (with schnorr) style wallets make sense for NW? Or is the reuse now far less important?
Andrew Poelstra
@apoelstra
yes, you can use derived keys (incl BIP32/44)
reusing keys is much more dangerous with MW than in bitcoin
lukap3rcic
@lukap3rcic
there is no bip32 "standard" with schnorr yet right? (it's my last question i promise :smile: )
Andrew Poelstra
@apoelstra
bip32 has nothing to do with the signature algorithm, you can use it with any EC keys
ed25519 has some specific bs that breaks BIP32, you may be thinking of that
