41  Bitcoin / Development & Technical Discussion / Re: Proof of Work: Limit node hashrate to improve decentralisation? on: June 05, 2018, 06:31:46 AM
You need to look up sybil attack. What constitutes a node? A port? So all the mining farms do is to split their existing hash rate over whatever you're defining as the limit so they're achieving the same goal.

Proof of Stake solves the sybil by just making it irrelevant on how many nodes your coins are sitting on...

Likewise PoW solves sybil attacks by making it irrelevant from how many nodes your hashrate is coming from.

Also keep in mind that PoS based schemes are arguably more prone to centralization than PoW. Their initial monetary base needs to be centrally issued as otherwise there'd be nothing to stake with, the rich get richer by definition and unlike PoW coins where you usually have a "division of power" into devs, miners and holders with PoS coins all three usually fall into the same, exclusive circle.

That's not inherently true. The coins can be issued with another algorithm, including PoW, where as PoW-problems will not be such an issue, since in an early stage of a coin's existence there won't be ASICs (if it's using a new algorithm) or alone farms for the coin.

It is only true for premine coins, but it should be clear, that premining a PoS coin is a totally retarded thing to do, unless you provide a plan for a proper distribution before you activate PoS.

Blackcoin for instance started with a PoW/PoS hybride that ran for a week and then was designed to switch to 100% PoS. A few thousand nodes participated in the initial mining and before the first bigger pools adapted the coin, the PoW was closed. The developers of Blackcoin never owned a significant amount of coins.

Similar for coins that already exist like Ethereum, these are decentralized enough to run a PoS.

Also with PoS the richer don't get more rich than other. Everyone gets the same interest rate for their balance, no matter if they own 1 coin or 100k, so the distribution of coins remains roughly the same and doesn't cluster up on a few addresses that been rich from the beginning. In PoW the rich, these that can run mining farms, get everything and everyone else gets nothing.

Bitcoin currently has 3 pools that provide almost 55% of the hashrate and Bitmain miners frequently get over 51%. That means the manufactor of the miners could attempt an 51% attack on Bitcoin with a good chance of success.

As said, getblocktemplate-protocol, if implemented thoroughly, lowers the direct danger of pool centralisation but only to some extend. The big pools and mining farms still have a political power in the coin discussion and need to follow coin updates in order to prevent a fork and manufactors of miners could hide a remote control in their firmware to attack the network.

Actually Satoshi did foresee mining farms:
https://bitcointalk.org/index.php?topic=532.msg6306#msg6306

Every wallet has build in a solo mine function. That's unused for years now since pools and ASICs took over and no one bothers to mine on their CPU let alone solo-mine. The initial idea was to run a decentralized peer to peer currency where every participant can at anytime participate to provide support for the infrastructure. That idea is completely broken by now as Bitcoin, Ethereum and other significant PoW coins are almost entirely operated by big mining farms and manufactors in China, who don't have any other interest in the coin but their mere profit. With that motivation, they run the network and influence the coin politics. And that is a bad thing and everything else but a dencentralized peer to peer solution for assets.

monsterer2 is correct. It is worth noting that exactly this inability to ensure that every node / user / market participant has only "one vote" (ie. the max hashrate permitted) is why PoW is applied to cryptocurrencies in the first place.

But that brings the known issues like that the BTC network is much less decentralized than intended by Satoshi. Originally it was meant to be mined on *every single user of the network*, with their mere CPU or lets say GPU. But the ASICs and mining farms totally wrecked this concept. Getblocktemplate lowers the dangers of (pool) centralisation a little but not the issue of huge farms like Bitmain providing alot of hashrate alone already.

ASIC-resistant algorithms are not a solution too to save PoW, as every ASIC "resistantce" has been broken sooner or later.

Maybe for Bitcoin and all other Proof of Work coins: Would it be possible to somehow limit the hashrate the network accepts from a node? Like what if you limit the hashrate per node down to what a normal desktop CPU can do. This would cause all ASICs become irrelevant and/or increase the effort to set up huge mining farms as these, that generate thousand and million times the hashrate of a CPU, would need to run as many nodes as their hashrate is above the abilities of a standard desktop CPU. It would also stop the need to create new algorithms that are ASIC-resistant just to be cracked a few years later.

You need to look up sybil attack. What constitutes a node? A port? So all the mining farms do is to split their existing hash rate over whatever you're defining as the limit so they're achieving the same goal.

Why then unite in pools? If the probability of getting a reward in solo-mining is equal to the probability of getting a reward in the pool (in proportion to its Stake in the pool).

For example, 50k blk is a pool. My Stake is 10k blk. The pool will pay me a reward in proportion to my Stake (10 blk). In a pool and in a solo, I get the same reward?

Pool staking only makes sense for those that don't want a Computer/Raspi running 24/7 to stake their coins. But it has two huge drawbacks:
1st you'd need to have to give all your BLK to someone else, which means you have to trust someone 100% that they don't run off with your coins.
2nd you'd harm the network's decentralisation, when the pool would have a significant amount of the network weight.

So, pool staking doesn't make much sense but brings huge risks, especially for your own coins.

(You can't mine BLK at all, it's pure stake)

Well, you can. If you mine other coins and sell them for Blackcoin. Much as the old Blackcoinpool did.
46  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [PRE-ANN] Blacknet (formerly BlackCoin) | Original research | PoS | No ICO on: June 04, 2018, 08:40:36 PM
Is there still no news about blacknet? Saw this topic changed from blk to blacknet a while ago, expected more information about blacknet.

As did everyone, seems to be another fad by rat4 Sad It just does not make sense to communicate this information and disappear afterwards again.

Blackcoin is now developed by other members of the blackoin community, contributors that are in the coin since the beginning. Rat4 did start a good thing but also later on was a blocker for further development as communication with him has been difficult. Blackcoin devs wanted to improve the project but didn't get past Rat4 so actually Rat4 announcing his own fork/restart as Blacknet could be good for Blackcoin since now it can be developed more independently.

what does it mean when it says on your panda wallet when it says interest generated but not accepted

thanks

That happens when you issue a valid block via staking but someone was quicker. The same can basically also happen with PoW mining but there usually only the pool sees it and not the minier.

PoW and PoS work basically similar: There is a process that by random determines someone who can create a block. In PoW this chance is lifted by your hashrate while in PoS the chances are tied to your balance. Both have the same purpose of limiting the amount of blocks someone can create to some value be it computing power or coin balance.

Now it can happen in the process, that two nodes get the same chances and create blocks at the same time. Then the one who issued the valid block first gets the reward. That's when you see a valid interest generated but not accepted by the network.

So tl;dr it's just bad luck.

Wouldn't it be possible that a computer AI is made specifically to calculate the addresses of bitcoin? And that when an address gets used it gives that AI a clue(the signature of the tx that is made by the address's private key). And when Someone stakes in a proof of stake coin, that address is constantly trying to make new transactions(staking) and alot of addresses that stake have over 7000 transactions from staking. Wouldn't it be possible that all these signatures are giving that AI magnitudes of clues that allow it to calculate the private key much easier?
In my mind it is possible. Can a cryptographer shed some light?

I am no cryptographer but... If you would be able to calculate the priv key from a signature, the whole internet security would collapse. A signature is a hash of an imput encrypted with a private key of the issuer. If you take the public key (the "bitcoin address") of the issuer, you can decrypt the signature and compare it's hash to the hash you calculate yourself from the input. This way you can make sure, that the input data you got was not altered after it was send the first time because that would make it a different hash. Every connection to a HTTPS-Server works on the same principle: A certificate for a secure connection to a website is basically a singed public key (+ metadata).

What you demand here is, that the cipher reveals parts of the private key. This would break the whole cryptography infrastructure.

Fuck the panda, fuck the project, the owner of the coin wants to scam the Asian's. The CEO/owner/primary dev of this coin is a scammer.. he is trying to sell more with this dead coin..  This coin is dead. Its a scam, you all have lost the money.
He is fooling everyone by selling lies about ressurecting the coin, rebranding and creating fake childish, gay logos. The coin went from 6 to 5 sat,
 then 5 to 4, now its between 3 and 2.. soon it will go into oblivion to 1 satoshi's. he owner wil then run away with all your money.. probably is a terrorist. I will soon expose this coin and the illegal things happening behind this


I would like to address this post because it is complete nonsense. First of all there is no "owner" or CEO of Pandacoin. There is however a development team of 10+ individuals (and growing) who dedicate a lot of their time to this project for little to no compensation.

Pandacoin had/has no Pre-mine or ICO so any coins that anyone on the development team may hold were obtained in the same manner as any other member of the Pandacoin community or anyone else who holds Pandacoin. That means they were either bought on an exchange, mined when PND was a POW coin, staked etc.  

The coin is far from dead and is in the process of a complete rebrand, if you want to get an idea of what we are working on, please check our 2018 roadmap found on the first page of this thread or on our new domain where our new website will reside:

https://pandacoin.tech/

In addition to the new website coming next quarter we also are currently running a logo contest which will pay a reward (Pandacoin) to the top 3 winners. More details about this can be found here, first place is 250,000 PND.

https://medium.com/@pandacoin/new-logo-contest-b91108cbde28

I find it odd that someone can make ridiculous claims but yet have no clue what they are talking about, Owner? CEO? This isn't a company, it's a community project being developed by volunteers. So I don't see how there is "illegal things" happening etc. 2018 Roadmap has been released and now we're working hard to get everything completed. Oh, and no we are not terrorists either and have no way to "run off with your money" because we don't have any of your money. So good luck with your FUD campaign, meanwhile, we'll be working hard to make Panda great again!

 

You are lying, you bloody terrorist supporter. There is a mafia man *terrorist* behind this coin. Soon this will be exposed you are scamming people in the name of this coin, taking their money and indulging in money laundering for unlawful purposes. You want to use the panda name to loot the innocent chinese and asian people. We will not fall in your trap. We all are working to unveil the truth.

Every project needs one or more imbeciles that troll the forums about it Cheesy

When I read something like this I know it's scam. it's a shit coin and the dev is a dreamer. good luck with these crap

This coin is 3 years older than your BT-account, mate. And it has a bunch of other PoS offspring that use it's technology. It's now reorganizing it's core team around the members that been active in the project and working on it constantly over the last 3 years.

Hello i was also scammed by Pandacoin few years ago ,
does someone can send me the identity of Wolong (scammer) please?
someone sent me it in PM but it was on my old account that i dont  have access anymore (due to forum hack)
what i remember the guy is from Malaysia , we all lost lot of money with Pandacoin .....soo much
i dream to visit him to get my money back
thank you very much

Pandacoin (this one) was actually once an anti-wolong coin. This project helped getting his scam pandacoin becoming a failure dead on arrival.
I heard he's active again on Twitter under his old account "GameOfDeception", but I have no proof, that it's the same guy.

So panda roadmap just dropped how long until the price starts going back up

The market is still bearish, Bitcoin just broke through 9k line and is at 2 months low. Literally every currency is in the red right now the whole cryptomarket lost 400 billion USD market capitalisation in the last month. I would be suprised, if PND gained any much upward movement at this time so far.

"2
I'm new to crypto and to PandaCoin but for some reason I had a good feeling about this coin so I bought some.
But..... I installed the Pandabank on my computer and the installation came with a virus and this makes me unhappy and a little worried.
Don't know what to think of this. The virus was Heur.AdvML.B.
Below is the information from Norton.


"Heur.AdvML.B is a heuristic detection designed to generically detect malicious files using advanced machine learning technology."
https://www.symantec.com/security_response/writeup.jsp?docid=2016-051811-2400-99

Heuristic detections try to predict what a software might do according to it's code.

Some Anti Virus will report coin software because there is malware that mines coins in the background hidden from the user. Pandabank doesn't do that. It however uses Proof of Stake to generate blocks and send the rewards to your wallet. That might rise an alarm in your Anti Virus.

Pandabank is open source and anyone can look inside the source to see that there's no malware or unwanted behaviour.

Looks like the ship's sinking.

You might be true.. they are hyping the coin here but there is lack of movement of the coin on the exchanges. Its ridiculious to sit and wait for things to happen.. while every other coin is making money and moving up.
I think panda made money before cryptopia went down and vanished. Now few people here are making up stories to minimize outcry.

Uh? Global marketcap lost like 300 billion USD during the last week. Literally every top 100 Coin including BTC, ETH and XRP are in the red.

Pandacoin maintains a rather horizontal movement while the whole cryptomarket lost billions of USD.

Roadmap and website redesign was announced not before end of January, yet people cry since mid January that "nothing is happening".

Honestly, I don't understand cryptomarkets. People sell under value, people panic at the slightest movement of BTC... when the market moves up, people flood the channel and want to buy "moon tickets" but dare a single day horizontal movement, everyone predicts doomsday.

Will panda ever raise again? or gone extinct? Dont see the major activity that was seen weeks back. whats going on?

I stumbled across this roadmap, don't know if this was supposed to be released already, but hope this will help you all.

This post and the image linked in it are made up and do not resemble what is in store for pandacoin in 2018.

Not sure what this user is trying to accomplish here.

I meant many sleeping coins have now started to trade on cryptopia, and are moving.. but the panda investment is stuck. Every coin that was trading on the day panda was on the top when cryptopia went down, have resumed business and are moving amongst the ranks, but panda has gone down into oblivion, have a simple question, is it wise to keep pnd coins on cryptopia or move it to some other exchange where its moving?

Best place to have your PND is your wallet at home where they are staking.

Hey everyone,

We need a plan for the next steps. I would love if everyone could help suggest jurisdictions as well as plans. For those that are interested, I would love if you could write what you would expect out of the non-profit and we can add all the ideas together to ensure that it is to the communities expectations.

Does it make sense to mine this coin, and what is its current course, can anyone know about the case? Huh

You can not PoW mine Blackcoin. It's Proof of Stake, that means blocks are mined using the coins in a wallet, which allowes to create blocks decentral with very low power consumption.

Altough you could use a multipool to mine other coins and sell out in Blackcoin.
