Topic: [ANN] [pre-sale] DapCash: First Post-Quantum Crypto Currency (DAPG) (DAPS)(DAPB) - page 2. (Read 2567 times)

Maybe, I'll disappoint you :-) we can't be in charge of other blockchains, they have their own developers, and only they can decide how to solve the problem of quantum threat.
What can we do? - We can offer the safest and the most anonymous post-quantum DapCash blockchain. As for other blockchains. What can they do? - They can implement quantum-resistant signatures, for example. But it is not always possible because of the architecture and source code of most currently existing blockchains.

You can start to mine after the full launch of the network. It will happen after ICO end (it ends on 7th March 2019) in the first half of 2019.

While Bitcoin and the basic altcoins are going down you have a chance to make a profitable investment in budding DapCash coins!
While foolish are gaining panic and selling out their crypto, patient and wise crypto holders are making profitable investments. 

Do you know anything about Shor's algorithm? If you would like to learn more about it, read our new article "Shor's algorithm against the blockchain": "Cryptographers around the world lived in peace because even a super powerful computer would have to spend millions of years hacking asymmetric algorithms. And in 1994, the American scientist Peter Shor devised an effective polynomial quantum algorithm for the factorization of integers. It sounds mysterious. Well, but why is it threatening?.."

Hi Permanent_Member! Welcome to the thread :-)

An ordinary computer, even a very powerful one, needs millions of years to crack modern encryption algorithms, such as ECDSA or RSA with a sufficiently long key. A quantum computer, as soon as it has the power of at least 1000 qubits, will be able to do the same in a few seconds.

Hello Sonata, nice to meet you here :-)

Bronze coins can't be purchased within pre-sale or ICO, they will be available after ICO end. So, currently, you can by silver or golden coins, or both kind of these coins - which you like. 

Dear community!
We have two news for you: good and very good :-)

1) We see a growing interest in the subject of quantum blockchain security and in our project in particular. Therefore, we decided to postpone the start of the ICO for two weeks: from November 23 to December 7, 2018. During this time, we will make a significant update of the ICO terms, so that the maximum possible number of investors can participate in it. Stay tuned!

2) work on the project and preparation for the ICO is in full swing:
- we are debugging and optimizing new digital signatures in our blockchain
- we are testing the code for vulnerabilities.

Currently, you still have the opportunity to purchase DAP coins at the lowest price!

19th November 2018, “Nature” - the reputable international journal of science - has published the article about the quantum threat:  “Quantum computers put blockchain security at risk. Bitcoin and other cryptocurrencies will founder unless they integrate quantum technologies, warn Aleksey K. Fedorov, Evgeniy O. Kiktenko and Alexander I. Lvovsky.”

We are pleased to see that reputable scientific minds fully confirm our point of view in their independent research. Here are a couple of impressive excerpts from the article:

“By 2025, up to 10% of global gross domestic product is likely to be stored on blockchains1. A blockchain is a digital tool that uses cryptography techniques to protect information from unauthorized changes. It lies at the root of the Bitcoin cryptocurrency2. Blockchain-related products are used everywhere from finance and manufacturing to health care, in a market worth more than US$150 billion.
When information is money, data security, transparency and accountability are crucial.
The blockchain business needs to update its existing software to use one-way cryptographic functions that are equally hard to reverse using conventional or quantum computers9. Until these post-quantum solutions are established or standardized, platforms must be flexible and capable of changing cryptographic algorithms on the fly.”

Hey guys! :-) Here are some interesting tips which would be helpful for you!

How to choose a budding ICO for investment?
Currently, the ICO market is going through difficult times. Too many low-quality projects appeared in late 2017 and early 2018, and now they are only abandoned sites and useless tokens. Against this background, it is increasingly difficult for project founders to earn the trust of investors and raise funds to develop a project.
Difficult times are not only for founders but also for investors. There are too many projects, and crypto-investors just don't have time to assess the advantages and disadvantages of each project. How to understand which project is worthy of attention? Here's what we think about it:
1) First of all, you should pay attention to the role of blockchain in a project.
If blockchain can be easily removed from the project and it doesn't change - well,  this project doesn't need blockchain. Crypto-investor doesn't need such a project either. Pay special attention to those projects that are unthinkable without blockchain, in which blockchain - based innovations are the heart of the project.
2) Look for projects that are unknown to a wide audience.
Have you found a project that is placed on all the top ranking sites? A project has a huge community and advertisement in the top crypto-media? Great! A project has a huge budget for marketing and.... what else? And most often it is the only thing that a project has. And even if the project is really great, too many people already know about it.
Look for projects that don't shout about themselves too loudly and don't throw money for marketing. These projects spend funds primarily for product development.   
3) Take a critical look at the project - what does it have except beautiful promises? Every decent project must have MVP! If the project team has already created at least something, it is hoped that the project will be brought to completion. 
4) Pay close attention to a project team. If a team comprise too many managers, advisors, and marketers it could mean those founders are primarily concerned about the image of a project. Don't get fooled by these decorations. In a decent blockchain project, the main role is played by developers.
5) Attentively consider the size of a hard cap. In fact, the development of almost any IT-project, including blockchain projects, requires not so much money. Well, a few million dollars for 2-3 years. If founders want to raise more than $ 10 million, think about whether to invest in someone's holidays in the Maldives or in someone's new Maibach. 

Nice to meet you here :-)

Ok, let's deep into a point by point :-)

DapCash and Kelvin

The common features of DapCash and Kelvin:

– Kelvin blockchain is developed on the same unique C-code as the original DapCash blockchain
– DapCash and Kelvin are both post-quantum cryptocurrencies and can resist a quantum supercomputer
– Both projects are based on multiple blockchain, which provides high speed of transactions in the network.

The difference between DapCash and Kelvin:

– Kelvin is designed for those of crypto-users who appreciate the comfort (smart contracts+, open API, convenient ID for the wallet)
– DapCash is more focused on network services that will be implemented only within the framework of this project: onion routing, DarkNet, VPN, etc.
– Also, DapCash places special emphasis on the anonymity of transactions and connections
– You can buy DapCash coins at a crowdsale (ICO), and Kelvin is not planning a public sale.


Three types of coins

It wasn’t just for fun.
DapCash is a multiple blockchain, in which various chains are created and exist. This blockchain architecture provides hassle-free network scalability and high transaction speed.  Also, it is necessary because of mining specifics, security and other purposes of subchains.
A Golden coin (DAPG) is a rare token with one block per 10 000 secs generation, classic PoW. Golden blocks are also planning to be used for establishing consensus between shards inside other blockchains that have shards. The Golden coin is rarer and little more protected from so-called 51% attack. Also, the Golden coin is topmost blockchain for the rest subchains, like Silver or Bronze.

A Silver coin (DAPS) is a general token with unlimited block size, one block per 100 secs generation, hierarchical PoW with sharded blockchain. Silver appears when you mine golden tokens, these processes are merged in so-called Electrum mining. This means that for each 1 golden coin 100 silver coins present.

A Bronze coin (DAPB) is a payment token. You can buy a cup of coffee or make payments for DapVPNand and other DAP services.
It is noteworthy DAPG and DAPS are more suitable for investment purposes. But you can use any type of coin to pay for services.

Have you ever thought about how to measure the power of a quantum computer?

Here (https://www.research.ibm.com/ibm-q/learn/what-is-quantum-computing/ )  we’ve found an interesting note about it:
 
“In order to increase the computational power of quantum computing systems, improvements are needed along two dimensions. One is qubit count; the more qubits you have, the more states can in principle be manipulated and stored. The second is to achieve lower error rates. We need to be able to manipulate the qubit states accurately and perform sequential operations that provide answers, not noise.
Combining these two concepts, we can create a single measure of a quantum computer’s power called quantum volume. Quantum volume measures the relationship between number and quality of qubits, circuit connectivity, and error rates of operations. Building larger systems with lower error rates will lead to discovering the first instances of quantum advantage, or applications where quantum computers can offer a computational advantage for solving real problems”.
 
A little complicated, yes? : -) In a nutshell -  the more qubits and fewer errors, the quantum computer is cooler! :-)))

Thank you for this note, we appreciate any opinion.
Currently, we are working hard on DapCash marketing :-) And it will be one of our priorities in the future.

An addition from our founder:
1) We don't use TOR and it's protocols but we are building our network on similar principles as TOR uses
2) You can mine DapCash using GPU (video cards), there are no restrictions. But GPU will not give any advantage over CPU

We are implementing these features in our services based on DAP platform:
1) The use of quantum-resistant encryption algorithms in protocols at the first level of data exchange. Even a super-powerful quantum computer will not be able to access encryption of this level.
2) Application of onion routing with garlic data packaging. Data packets will be put in a united stream and protected with at least two layers of encryption (three layers of protection in total).
3) Additional features for "obfuscation" of traffic: throwing back and forth someone else's traffic, mixing with fictitious traffic, the use of ring signatures. And all these in order to ensure the highest level of data transmission security.

For all transactions, we'll use the post-quantum annotation Picnic – an algorithm based on a zero-knowledge confirmation, as well as ring signatures and multiple signatures.

As for mining, we are against mining farms, Asics and mining centralization. At first, DapCash mining is designed for CPU. But I will ask our developers if CPU is exclusive.

Our team has focused on development for the last year and now we have something to enjoy the community 

We have an MVP, namely: a working testnet, a wallet, a working VPN service and we have our own SDK. Our team is also developing a Warehouse Management System for B2B clients.

This month, December, will be started the 3rd round of DapCash tokens presale. This round DapCash Bronze (DAPB) premine will be released in our testnet.

Stay tuned, more details coming soon.

Is this project still runing?

This article gives answers to many questions. we all believe, that the cryptomarket for crying will be able to rise in the near future. I think? this may happen after the Chinese new year

I bought some DAPG in February 2018. Now I cant access my account on dapcash.org . I tried resetting my password twice in 3 weeks and did not receive any email.

what will happen after live-coin period?

What does it mean? what is the difference between ICO and coin distribution period? never heard about the second one
