Krótka, bardzo ładna animacja, miejsce na małą dyskusję?
--- Przypominam że Peercoin w DISTbIT sprzedawany jest BEZ PROWIZJI ---

http://m.washingtonpost.com/blogs/the-s ... ernatives/In addition to the energy savings, advocates of proof-of-stake currencies like Nextcoin and Peercoin argue that it makes the network more secure against takeover attempts. Recall that you could take control of the Bitcoin network if you obtained a majority of the network's computing power. With a proof-of-stake currency, on the other hand, taking control requires gaining a large share of the outstanding coins. For a successful virtual currency like Bitcoin, that could cost billions of dollars. And a successful takeover would destroy confidence in the currency, devaluing those same shares. This, advocates argue, provides stronger security than Bitcoin's proof-of-work scheme.
Jordan Lee pisze:The Peershares implementation and extension my team has been working on will be known as the NuBits project. It provides something which the cryptocommunity has desperately wanted and needed for years. There are presently no implementations or competitors with a production system up and running to meet the need. It will be a ground breaking release. Some might even call this the most important development in the cryptoasset space since Bitcoin was released. Others will disagree, but there will be a consensus that it is an historic development in decentralized finance...
Janowicz nie może się z tym nadal pogodzić.kactech pisze:...Bańka na DRK raczej już się kończy, przynajmniej należy spodziewać się konkretniejszej korekty, także kolejny raz(Doge, NXT, Aurora, pewnie coś jeszcze) odzyska 3 miejsce pod względem market cap...
Sunny King pisze:I have never claimed that you need both 51% PoW and 51% all coins to attack peercoin. That's a misunderstanding of peercoin's security. Peercoin's security is 100% proof-of-stake, so in terms of security it's not really a hybrid system. So you don't need 51% PoW. You need and only need to attack proof-of-stake.
Also, you don't need 50% of all coins, you only need a significant portion of active minting coins for a '51% attack' (in bitcoin's terms), which includes the ability to DoS the blockchain. However this does not mean peercoin's security is then weaker than bitcoin's. After 6~7 years, bitcoin's inflation rate would be close to 1% annual. Let's assume that the mining capital has a lifecycle of 3 years, then you would only need 3% of bitcoin total coin stock value to permanently 51% bitcoin blockchain. Of course, bitcoin's inflation would drop further after another 4 years, and so on. So we are kinda of looking at bitcoin's security at most a couple percent of total coin stock value.
Currently my rough estimate of peercoin's 51% security is at about 1M~2M peercoins. That already puts us ahead of bitcoin's future. Unlike bitcoin, peercoin's security is not a function of inflation rate. Over time it would only strengthen as coins are more distributed. With the features that reduces minters' risk while improving incentive are introduced, we are looking at a good leap of security level further.
Trwają również prace nad portem btcd dla Peercoin, serwer już działa, weryfikuje i rozsyła bloki, wymaga jeszcze implementacji reguł przeciwko atakom DoS.NuBits pisze: NuBits will be released September 23, 2014 at 14:00 UTC. “Our solution completely solves the volatility problem cryptocurrencies have experienced. It does so with zero counterparty risk using a decentralized network.” (self.peercoin)
