the timestamp doesn't matter, it's who can get their stuff to the most other people first in cases of simultaneous solves.

Yeah but bitundo is basically just an automated variant of the tx malleability attack. You just replace your first "mistake" transaction with one submitted to the special pool that sends it back to you minus a fee, and hope your undo pool wins.

Its not really going to gently caress up bitcoin or cause double spends as long as people keep waiting for a reasonable number of confirmations.

waiting for a reasonable number of confirmations

The most common rebuttal against somebody saying it takes an hour to get the six confirmations specified in the whitepaper is the claim that you don't need any confirmations.

True, the node might see the double spend going around the network, but if it doesn't, the merchant is out of luck.

there's a lot of reasons to tell bitcoin cultists they are stupid for technical reasons, but i think the one that angers me most are the societal reasons that they suck so loving much

these people are so goddamn ignorant to any perspective but their own and their confirmation bias is turned all the way up to 11, they see people who can't use computers or can't conceive of what "Bit coin is" to be unintelligent and not worth their time. they cannot comprehend that 99%of society will have different priorities than them that for the most part don't directly involve technology in a conscious way

I mean yeah its basically going to be used to rip off people that are impatient or don't understand how bitcoin works, plus the small percentage of use cases that actually do gently caress up and send it to the wrong address.

Honestly though if you don't want to sit around with your thumb up your rear end for an hour why are you using bitcoin. Or even if you do.

oh and thanks for the serious talk it was p interesting

only thing i have to add is that the byzantine thing doesn't take into account the relative ease in dunking your adversary's pool, at least compared to onlining enough hardware to get a 51%

it only works if you have the highest number of current miners (otherwise the pool above you gains 51% before you and keeps it) but it also has the side effect of forcing the orphaned miners to revert to a backup pool, and if you're already top tier in the electricity murderer olympics odds are you're somewhere on most failover lists

right now for whatever reason ghash.io is down from it's usual 40 something % share to 28%, so they would need to remove up to 6 pools assuming the miners stay offline, much less if they join up

in most cases it used to take only one pool to knock down (like when the last hard fork happened and basically 3 dudes decided to stay with the small blocks, DEMOCRACY!) and you have majority for a while

not sure what you'd do with it, but heh

Nov 4, 2009
there was also that paper like 6 months back or something that showed how a dishonest pool could do a 51% attack with only 30% of the network if they were the largest single pool due to the fact that they could not report blocks and start working on the next block, only reporting blocks when they saw another pool had reported a block. This would give them a time advantage to work on a second block, and once you are 1 block ahead of the network you can stay ahead through having more time to work on subsequent blocks before the rest of the network is able to. i dont think anyone has started doing it yet though.

I SHOULD KEEP MY DUMB MOUTH SHUT INSTEAD OF SPEWING HORSESHIT ABOUT THE ORBITAL MECHANICS OF THE JAMES WEBB SPACE TELESCOPE.

CAN SOMEONE PLEASE TELL ME WHAT A LAGRANGE POINT IS?
8 months ago, I proposed "the next social network", with user-controlled privacy, built-in tipping, anonymity by default, and more. Today, netvend is completed: a working prototype of the backend for the network. The hard part is done. All it needs is an interface, and Coinflow will be a reality. (self.Bitcoin)

submitted 2 hours ago* by syriven

Some of you may recall my first post about this project, which you can read here. I wasn't calling it Coinflow at the time, but the post proposes a way to build a social network with the following characteristics:

User-controlled privacy (via encryption)
Totally transparent and open-source
Completely neutral
Impossible to corrupt
Open to anyone
Pseudonymous/anonymous by nature
Built-in tipping
Open to all developers
Competing/complementary interfaces will share, rather than fracture, the community
Free of both ads and spam
Tips go straight to content providors

When I wrote that post 8 months ago, none of it was built. Today, the backend is completed and functional. I'm calling it netvend, and you can read more about it here. This was the hard part, guys. We're very, very close to making Coinflow--the social application of netvend--a reality.

Netvend can facilitate Coinflow today. Coinflow is really little more than an interface, given that netvend already exists.

And that's where you guys come in. I'm looking for any Python developers that want to help build Coinflow, as well as developers in other languages who understand crypto (to further expose netvend, and therefore coinflow, to other languages). It took me 8 months to get where I am today, but with even a small group of developers, I believe we can have a usable first version of Coinflow within a month, which supports all of the features listed above.

I know how to build Coinflow, and if I have to, I'll do it myself. Alone, it will take me a while, because I've got to spend a lot of time paying the bills in the meantime. But if I can get a group of interested developers, I can justify burning through some savings to get this completed as soon as possible. I know how to get us there--I just need some man-hours.

Thanks for reading! Let me know what you think!

[–]syriven[S] 3 points 2 hours ago*

First of all, since the whole thing is open-source, you can call it whatever you like ;)

The reason I like coinflow is because of the way content is aggregated and filtered, as discussed in the post from 8 months ago. Basically, when I see a post I like, I can tip it. This makes all of my friends more likely to see the post. They can tip it, and the cycle continues. So, content rises based on how the coins flow, and while a given piece of content rises in popularity, the poster of the content is receiving those tips directly.

That's not to say that some dude with a lot of money can shoot his post up to the front page, because that dude's expenditures will only affect the feeds of people who've tipped him.

[–]syriven[S] 2 points 2 hours ago*

Actually, this is not technically decentralized. Netvend is a centralized server, that attains the perks of a decentralized system through other means.

Netvend (and therefore coinflow) stores its data transparently, in such a way that any interested party can confirm for themselves that no funny business is going on.

Whereas the blockchain is difficult to corrupt in the first place, netvend is not quite the same. Rather, if netvend/coinflow were compromised, it would become immediately obvious to the clients, which would simply refuse to trust the server until it was restored. This is because the entire database is supported by cryptographic signatures from users, which support whatever action the database claims they performed. These signatures are unfakeable, and can be checked by any party at any point, as the database is open to anyone.

[–]syriven[S] 1 point 16 minutes ago

I haven't heard of that. It could be something to look into when the time comes to move to a different server.

At the moment, netvend is just hosted on an amazon AWS instance, mostly because it's nearly free at no use, and scales with increased usage. This aligns nicely with the netvend fee structure.

As soon as coinflow and netvend gain some momentum, netvend will probably be tried on several different kinds of platforms.

[–]syriven[S] 1 point 1 hour ago

I see coinflow and netvend as the first of many--more of a type of tool than a brand of one.

Chances are good that specific coinflow clients will have different (and likely, catchier) names, and "coinflow" will refer to the network that those clients interact with.

Similarly, I think we'll see several different "netvend servers" in the future, and again, these will each probably have their own name.

[–]syriven[S] 2 points 2 hours ago*

I will agree that this has been a challenge for typical networks. However, I would argue that Coinflow has a very unique advantage:

Let's say that, at some point, Coinflow is working and has a small pool of users. If any one of these users has a cool idea for a feature, and has the skill to implement it, they can do so. Their own version of the Coinflow client will still have access to the same community--even though they're using a modified client. This applies even if they write their own client from scratch, with a completely different idea of how the interface should be designed.

Facebook evolves as fast as a small, closed group of developers can build it, but Coinflow (as with all netvend applications) can develop as fast as its whole userbase can build it.

[–]syriven[S] 4 points 2 hours ago

I'm talking like a programmer, because right now, programmers are what I need.

Users don't have to care about this advantage directly. Coinflow will begin with unique advantages, far beyond what other social networks offer. And when someone has an idea for an improvement, that idea won't have to be heard about and approved by some centralized group: it will be in the hands of the open-source community, to use or not, as they see fit.

[–]syriven[S] 1 point 2 hours ago

In addition, while Myspace, Facebook, and Google+, are effectively different implementations of the same design, coinflow will offer advantages that other social networks simply don't even come close to having. See the bulleted list in OP. Many of these are unheard of on any existing social network or platform.

What did google+ really have that was new? Personally, I was rooting for it mostly because it wasn't Facebook--that might as well have been their slogan: "Google+: it's not Facebook!"
