how the devs solve the problem with 51% attack?
it is very possible in sustain stage, dont you think?

it is the same probability to 51% attack as bitcoin has?

i also have a problem. Yesterday i try to withdraw some realBTC. today i saw that my withdrawal is stoped and i have 7realBTC more on my acount and -11goxBTC. what is going on ?

im waiting too for realBTC. yesterday they sent me 0,08BTC, but today they didnt. Instead of that the realBTC go back to balances and also i have more realBTC, and -11goxBTC. What is going on there??? Yosh ? my email: atlon11mb@o2.pl

anybody make a deal there? it is still working ?
7  Economy / Currency exchange / Re: MTGOX <-> BTC BID/ASK on: February 14, 2014, 03:09:16 PM
WTS goxBTC @ 75%
you send first -> we can make very small amount for first deals.

up
anybody know which of CPU coin is worth to mine ?

in next 3 days we will cross difficult 10. Isn't it exiting ?  Smiley

this is a rumor or Novacoin will be a Time magazine soon ?
11  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency on: November 24, 2013, 01:07:55 PM
can somebody look at this article:
http://www.wired.com/wiredscience/2013/11/prime/all/

it means that there is no large gap between large prime numbers ? and the prime numbers go to infinity? so this is very good news for primecoin? the PoW could be more safe then SHA256, right?

this case reduces confidence to this cryptocurrency sooooo much.. i just can't understand why baltazar do that. A lot of people sent their design and waiting for this voting
13  Alternate cryptocurrencies / Altcoin Discussion / Re: [PPC] New York Times Interview on: November 22, 2013, 01:29:46 PM
did you say something about PrimeCoin in this article ?
14  Alternate cryptocurrencies / Altcoin Discussion / Re: Primecoin is STILL our best investment advice, recent actions verifies the shift on: November 22, 2013, 12:32:44 PM
i have prime coin, and think it is innovative, and was the only coin I have mined.

Diversification is the biggest draw, and that Sunny King was the DEV


a lot of people talk about diversify now between technology. So:
-> first new innovation: Namecoin
-> first scrypt coin: litecoin
-> first POS coin: PPC
-> first scrypt+pos: novacoin
-> first new POW (the most importatnt if something go wrong with SHA256): Primecoin


so this coin should go up the most i think. primecoin lost the most of all these becouse of bad short-term news. So i think that it could skyrocketing in next days/weeks

I've been away from primecoin for some time. Is it still mined with CPUs?
yes. some guy claims that he has a fast GPU miner but he will public the source code on 1Q 2014. you can read about it here:

today i mined my first block of primecoin (solo mining)
awsome feeling - I've mined it for last 3weeks

Anyone know the answer to this :  does encrypting your wallet (putting a passphrase on it) end all your PoS minting irretrievably?

Like say hypothetically some guy was trying to mint pos blocks, and he waited 20 days with nvc in his wallet, then he put a password on the wallet, is all the minting contributions / pos work lost?  I -- errhhh--- I mean some guy were to remove the password immediately after putting it on his wallet, would it just resume where it left of regarding PoS minting, or would all the work be lost ?

THanks.
when you open wallet without password after 30 days you will mine POS block - dont worry. Now you should focus how to unlock your wallet.

PrimeCoin (XPM) = 12xfaster then Bitcoin, usefull in science, good press, unique!, probably more secure then SHA256, smooth reward dropping, CPU mining (everyone could do it).

people should read more about this coin. I make a lot of research and can't find better project. Maybe NVC (with CAP of 10 NVC per POS) could  rival.

Now the problem with price is becouse people were waiting for difficult 10. after ypool down - many people was disappointed (me too). But this is short term factor - by the end of the year we should reach difficult 10 and the reward will drop 10-15%. Another bad factor was maco and his scam-promote project. He told that he will find good people and promote primecoin, but he did nothing. Another short-term bad factor is talking about GPU miner and big dissapointed in this area.

This is only short-term factors and i belive that we will see XPM/BTC at 0,1 in the future. Maybe one, maybe 2-3 years. We will see. People who invest in cryptocoin couldn't miss XPM becouse if SHA256 will be broke then XPM will survive - everyone need to be diversify.

last block i had 8,7% per month - like 10 days ago. So keep NVC is very profitable Smiley i also fun

but im not sure if we got good devs. they promised to relase logo and banner 3moths ago. A lot of people sent them their desing hope for reward, but they still didnt publicated it.

2 very important questions and anserw by Sunny:

questions:
1. from wikipedia http://en.wikipedia.org/wiki/Primecoin "To meet this requirement, the size of the prime numbers in the system cannot be too large". What could happen when we cross 10 or 100 mln block and the prime numbers start to be large?
2. "If the coin is successful and prime number theorists can use the results to find an equation to predict prime #s, it would essentially break the coin's PoW." -> is it possible?

answers:
1) Prime size would stay same. The prime chains aren't going to be exhausted. There are countless prime numbers, basically as abundant as numbers themselves. Remember there is a prime every couple of hundred numbers at the scale primecoin miners work. So for a 256 bit number there are more than 2^248 primes, so that's not far from 2^256 which is the total numbers at 256 bit.
2) Prime number theory is an extreme hard discipline, with hundreds of years of history. So it's not very likely to happen overnight. I'd say even if you throw trillions dollars at such research it's not going to produce that type of results on demand. Also, even if you find a super efficient mining algorithm doesn't mean you 'break' the proof-of-work system, it just means you have an advantage over the public before you publish the findings. The difficulty can scale enormously in primecoin's design.
--------

its quite optimistic. those 2 questions were my major doubts about prime. now i think that this model of PoW could be more safe then SHA256, which could have some problem when quantum computer appear on the market.
