Will Peercoin be next to rocket up?

The technology that has quickly gained 1/7th of the Bitcoin market recently, was successfully implemented by Sunny King 3 years prior.

Sentinelrv: I last spoke to Sunny about this in April 2015. Here are two quotes from that conversation...
 
"As to cold minting feature, I am not interested in getting into a feature competition with a commercial project like neucoin. If they want to claim they got there first, then so be it (I thought NXT already had it). We have to get full understanding of all future implications, including long-term support cost with regard to bitcoin merges and so on. There are important difference with a commercial project and a volunteer project, a commercial project can afford to increase complexity and just deal with it by throwing money after it. Whereas a volunteer project, increase of complexity could very much mean the end of it."
 
"As to Mike's work, I am by no means degrading Mike's proposal and implementation, it might very well be accepted as is later. And I very much appreciate what Mike has done to peercoin project. The thing is, I haven't yet given enough thoughts into the implementation details, I guess others are probably in the same boat. So in my opinion we need to be patient. We want to be sure to be able to fully support the feature for many years down the road."

People don't like buying cheap products like PPC and NMC. People will rush to buy PPC and NMC when their prices go up.

Will anybody dump Peercoin? to $0.1 or $0.01 ... ...

"lots of promises from devs", promises are only promises.

Sunny King said: "Idea is only the first small step, execution is 99%".

ETH already took $18M by IPO and it premined 12M ETH for the devs now. ETH is a true blood vampire.

4.No wallet
What is the devs working on? I bet that ETH will go to $0.05 by the end of Aug.

to $.05 within a month

当数字货币（比如，比特币等）等同于法币的时候，数字货币的优势就能体现出来。 届时，在银行，机场，邮局等场所，可以很方便地兑换数字货币和法币，如同现在的外汇兑换一样。

该IPO失败，所有资金早已退还给投资者。

• 基于最近比特币网络的交易量，我想谈一下PPC和XPM的交易费策略。我始终认为比特币的交易费方案过于复杂，因此我简化了PPC和XPM的交易费策略，使得用户很容易理解。比特币更深层的问题是，基于去中心化的技术，网络的费用非常的昂贵。这意味着它更适合于作为骨干货币，而不是跟中心化的支付网络竞争成本和交易量。这在比特币的用户不是很多的时候并不明显，但是在它越来越流行以后，问题会越来越明显。
• 起初，比特币的交易费被设定在0.01BTC，事实上我认为这非常好，它好于一个过于复杂机制。试想一下，即使以比特币现在的价格，0.01BTC的交易费仍然只相当于银行转帐的十分之一。现在，增加比特币网络的交易规模，去跟Paypal和信用卡等竞争，将会使比特币的去中心化优势丧失。而去中心化是比特币最核心的东西。很显然比特币的开发者没有很警惕的守卫比特币的基础原则。
• 在这一精神指导下，PPC和XPM使用0.01币每KB数据的机制是非常简单和有效的，它跟最初比特币的设定一样。比特币的情况将会被紧密的观察着，PPC和XPM的交易费策略将会保留，即使未来基于比特币代码的升版而升级PPC或XPM。

Weekly Update #150

• With the recent transaction volume on bitcoin network, I would like to discuss the transaction fee policy of peercoin/primecoin. I have always felt that the transaction fee design of bitcoin is overly complex, so peercoin/primecoin simplified it quite a bit, so users could have easier understanding of the policy. However, the deeper issue with bitcoin's technology is that, due to the nature of the decentralization technology, it's inherently a rather expensive settlement network. This means it's more suitable to act as a backbone network for financial systems, rather than to compete with centralized payment networks on volume and cost. This isn't obvious when bitcoin userbase is still limited, but the situation will get more and more obvious as its popularity grows.
• Originally bitcoin's transaction fee was defaulted to 0.01BTC. In fact I think this original default value was quite good, it beats having an overly complicated system in my opinion. Think about it, at current valuation it's still only one tenth the cost of bank wire networks. To prematurely increase the scale of the network, to compete against networks such as paypal or credit cards, would cause a significant loss of decentralization which by the way is what bitcoin technology and philosophy is all about. It appears that bitcoin developers are not guarding the fundamental principles with enough vigilance.
• In such spirit both peercoin/primecoin set default transaction fee to a required 0.01 coin per KB of data, in a simplified and effective fee policy from old bitcoin. The situation in bitcoin is closedly watched, the current fee policy in peercoin/primecoin likely would remain in place when upgrading to latest bitcoin codebase in the future.

Have fun!

I purchase PPC as an investment. I also like the PoS principle.

What are the highlights of this book?
What is this book's price and where can I purchase this book ?

I think the most important here is this:

Quote from: Sunny King on April 29, 2015, 07:42:31 am

"2) From bitcoin/peercoin core point of view, these probably can be pruned immediately from unspent set. Note pruning does not remove it from blocks. It's still on the blockchain and can be retrieved from blockchain at any moment albeit with higher access cost."


First pruning doesn't mean we shrink the blockchain. Some nodes will have to keep prunable data forever, whether there's a special flag or not. It is required so that new nodes can validate the blockchain. If there's anything missing in the blockchain you can't validate it.

When we talk about prunable data we mean that a client can delete these data from his own copy of the blockchain after he used them to validate a block. He won't need these data to validate future blocks. But then he's not a complete full node anymore, because he can't provide the full blockchain to others.

Second, anyone who doesn't use these prunable data and doesn't want to store the complete blockchain can delete the prunable data just after he received it. So a flag is not necessary: prunable data already means you can delete it as soon as you want.

This flag could be a hint, suggesting how much time nodes should keep it. But this decision is more a matter of how much they want to be a full node, and has nothing to do with the emitter or the data itself.

注意它仍然在Alpha版，并需要PPCoin核心V0.5版（还未发布二进制文件，所以你必须自己生成）。

开发正在进行中，着重点在于：

 - 把点点信变为有两种消息类型。一种是接收者低级别匿名性，这意味着不需要每一个客户端必须下载它，这种类别超级便宜；第二种类别将比较昂贵，接收者完全匿名，并且要求所有参与的客户端下载它来检查是否他们可以将其解密。

 - 已经开始开发一种轻型客户端。轻型客户端不需要点点币核心伴随运行。它的主要目标是移动设备。这些客户机将不会被连接到点点币网络，但将连接到超级节点。超级节点根据请求发回来自区块链的经过解析的数据。
数据将被签名，因此轻型客户端不必信任超级节点，但需要数据审查。


Emeth还提到 Peerapps框架的另一个应用是市场（Marketplace）。
