I've read a few things about the new RGB project, could it be used for Grin?
Ignotus Peverell
@ignopeverell
I haven't looked enough at specifics to tell
I agree with @BigRomanov that confidential assets may be interesting too, especially if we can figure out some pegging system with other coins
I'd love to have some sort of bitcoin bridge where bitcoin assets can exist on the Grin chain

at some point, I remember it was stated that cuckoo cycles would be more energy efficient, because the bottleneck being GPU memory bandwidth.
Is that still correct? if so does, anyone have an estimate for how much of a reduction in energy usage this means?
Say I look up the specs of my favourite GPU: does that mean i can divide that power consumption by some factor?

Hi @BigRomanov you have some small mistakes in your comparison table, for example for Monero the "Privacy enabled by" should be: "Ring Signatures + Confidential Transactions + Stealth Addresses".. Also for BEAM the "Decentralized" should be "No".. I also suggest you add row "Funding Model" with "20% tax from each block reward" for ZCash/Beam and "voluntary donations by community" for Monero.. oh and you should add Grin to the table.

all this new privacy coin stuff made me feel like sharing this, which i came across today.

it's a link to white paper for ViceCoin. make of it what you will. i found it quite amusing.

@meoat33 with the latest cuckoo cycle miners, GPUs use quite a bit of power.
meoat33
@meoat33
@tromp when talking about power consumption for GPUs: is it correct to say that different processes (fetch from memory, compute hash, etc) require different amounts of energy, thus if one of these is the bottleneck this gives how much it will at most consume?
John Tromp
@tromp
GPU has many components using power. you often get highest performance when exercising all components near capacity. this will also use the most power.
if one or more components is under utilized you will see drop in power but that suggests there are ways to improve performance

Interesting article on the MakerDAO governance model they are developing. They are a very transparent and wholesome project so they are worth following I think https://medium.com/makerdao/foundation-proposal-caeb382465c1
also other than beam what other projects with code are working on implementing mimblewimble?
Ignotus Peverell
@ignopeverell
I don't know if that Ethereum ICO one went forward, mythril I think?
lehnberg
@lehnberg
@0xb100d @ignopeverell there’s also http://mimblewimble.tech:
  • “Mimblewimble on ethereum”, maybe as some kind of side-chain? Not clear exactly what the project is about.
  • Led by the “former co-founder of Zcoin” and the “ZClassic cofounder”.
  • Not clear what the status of the project is, it appears to be inactive.

@mfronczyk
@BigRomanov do you have any addressing layer, or coins are just sent to IP addresses?
jaspervdm
@jaspervdm
Am I the only one who doesnt like all the beam questions in here? They have their own communication channels, the main topic here should be grin :)
(note its just my personal opinion, im not a mod)
Alex Romanov
@BigRomanov
I am only answering here because I am asked here. I had no intention to impose. Everyone is more than welcome to ask questions in our Community Telegram Channel https://t.me/BeamPrivacy
jaspervdm
@jaspervdm
yeah i am not blaming you, just more the people asking the questions :D
Alex Romanov
@BigRomanov
@mfronczyk Yes, we have an addressing layer and support for both online and offline transactions.
Michał Fronczyk
@mfronczyk
@jaspervdm, I thought that we might learn something from Beam. AFAIK, Grin doesn't have a clear plan for these. @BigRomanov can you tell how this works, how the addresses look?
jaspervdm
@jaspervdm
@mfronczyk yeah i guess, it just feels like the main topic atm. but again, just my personal opinion
John Tromp
@tromp
i'm fine with beam discussion here, as long as it doesn't drown out grin discussion (which it's nowhere near to doing)
jaspervdm
@jaspervdm
alright it doesnt seem that anyone is sharing my opinion so i will shut up about it haha
umma08
@umma08

the reason there are so many questions about Beam is perhaps because they have a link to their codebase (i assume that is what the github icon in find us in for) that doesn't actually link anywhere.

The twitter and telegram links do work though, and they also have a contact form. unless of course i am mistaken, and they do have an open codebase.

lehnberg
@lehnberg

@umma08 they say their codebase will be released following the launch of their testnet, which is currently targeted for September.

For what it’s worth, I think that any constructive discussion and knowledge sharing between our projects will be positive, and I agree that there are opportunities for us to learn from each other.

Just like @mfronczyk I too am curious to hear more about the approach @BigRomanov and the Beam team took for their addressing layer, and how they support both online and offline transactions.

umma08
@umma08
@lehnberg yes, but if the codebase was their, i assume people could just look there. the fact that it is not means people have to ask questions
lehnberg
@lehnberg
Indeed. (:
umma08
@umma08
the questions are symptomatic of the opacity level
hokkanen
@hokkanen
what is a grin tx size relative to btc?
Alex Romanov
@BigRomanov
@lehnberg @mfronczyk Yes, we thinkg the addressing layer is important. Even though the address is not part of the transaction and is not recorded in the blockchain there still should be some mechanism to allow wallets to find each other and establish initial connection in a way that allows user to verify the identity of the other wallet . This step is actually a major security issue since it is vulnerable to spoofing and man in the middle attacks. In our opinion, the initial address exchange should occur out of band via a secure channel. This can be done via a centralized secure messaging service, such as Telegram but we are considering implementation of an encrypted decentralized messaging system, for example based on secure distributed hash tables. The system is planned to be built into our walelt. That said, we are still in the process working out the details of the architecture and implementation for this layer.
umma08
@umma08
is there a reason block height on grinscan.net seems to have stalled?
last block 17m ago? is that just variance, or is nobody mining testnet?
Yeastplume
@yeastplume
testnet 3 is imminent so there are probably fewer people using t2 now
Janus Troelsen
@ysangkok
did grin-miner catch up to gold miner?
Yeastplume
@yeastplume
there's a meaner-miner plugin that implements the same algorithm now
Janus Troelsen
@ysangkok
i am considering retrying trying the miner on Google's cloud with P100 GPU's. (didn't work last time)
ok
i'll test again when testnet3 is out
Janus Troelsen
@ysangkok
Yeastplume
@yeastplume
slightly, yes. It's just missing the two cuda plugins that now exist
umma08
@umma08
is there some consensus around what would be an effective/efficient hardware setup for grin. is it worthwhile getting a dedicated GPU chip/miner?
Yeastplume
@yeastplume
I think at the moment it's more a case of waiting to see what's going on with the next generation of GPUs
And then who knows what will happen ASIC wise... so I don't think anyone can really answer whether getting something is worthwhile. We can only say a 1080ti is the fastest as far as we know
