Bitcoin Forum

Hello everybody, I'm happy to announce the new crypto currency DapCash - quantum apocalypse resistant crypto currency with post-quantum zero knowledge transactions. More details on our site, https://dapcash.org
Its not a fork, DapCash is based on original high performance codebase, written on pure C ( https://github.com/demlabsinc )
We're planning to release 3 different token's types, processed by the one DapCash networks - gold (PoW), silver (sharded PoW)  and copper (DPoS).
Mining hash functions is CPU optimized.

Would be happy to see any suggestions, advices and etc

UPD. !! Golden tokens Pre-sale started  !!
UPD. !! Silver tokens Pre-sale started  !!

Site: https://dapcash.org
White papers: https://dapcash.org/files/White-Paper-EN.pdf

looks like the site is empty, please provide any more details.

I've never understand this quantum resistant coins. Still, things that we know about quantum computers are limited but we have already OQS algorithms. Could you please explain to me what is this OQS algorithms? How do they work?

Thanks

how to mine this coin? what is pre-sale minimal size of investments? I did not find information what is a soft cap? where is your whitepater? thanks

Omg... can't say its empty. May be not all things are finished, but some information is present. Some additional information is in git but thats just sources, huh, https://github.com/demlabsinc

In anyway, you could ask and I'll try to answer. My apologizes, we just started the project and I'm newbie in this.

Yes. Let me try... OQS is Open Quantum Safe - https://openquantumsafe.org/  if you want more details its better to read on their site.

In few words, they work like usual assymetric alghorythms but based on different math operations. For example, RSA is based on factorization thats already has quantum alghorythm that could crack it in polynomal time (so-called Shor's alghorythm). Elliptic curves is based on... elliptic curves :) they are also vulberable for quantum calculations but only in theory.
Post-quantum is mostly based on so-called lattice based encryption thats are not vulnerable for quantum computers, mostly because it requires to store lot of intermediate results and memory in quantum calculations is bottleneck. Thats why hash trees are also quantum resistant. So, replace block in the blockchain its impossible. But with quantum computer with thousands of qubits you could steal the Bitcoin wallet, for example. Or ever mine all the rest blocks.

There are also another post quantum signatures, based on supersingular elliptic curves, ring with errors and etc. They all are also mostly based on exponential grow of memory usage for calculation, btw that does some problem with their optimization - usual PQ signatures load CPU a lot and have big size of sign and public key.

Mining is CPU optimized, as Monero has, best for that would be x86_64 CPU with at least 3Mb L3 cache per CPU. Or another variant - old smartphones with ARM NEON CPU. Nearest time we'll do the measurements to understand which variant would be better.

Minimal size we still not defined... what you could advice? I think about 1 ETH, thats for one gold token. Or 1000 silver. On pre-sale we're thinking to sale only gold.

About whitepapers, they are almost ready, left only to describe consensus and translate them in English. When we start pre-sale everything will be ready.
At least drafts I could show you I think, here is it https://docs.google.com/document/d/12DA-mHAER6JDDtJeufYLHtfFbECyeFXXJ8OgtzeoleA/edit?usp=sharing

Looking for a new project, so following these one to.

I think the main thing about crypto coin is usage. Mining is a technical detail. Most of the new coins doing same mistake and showing the advantage of coins  technical details, not  the usage of coin

Good notice, thank you. Thats because we're developers, not sales agents. But I'll try to say smth about usage.

1)  it will be safe. Really safe. You could purchase coins and not worry that smbd steal your wallet with quantum computer.

2) Holy Grail of crypto currencies - fast transactions. Becasue of multiple blockchain, we'll have lot of blocks where the transaction could be placed. So they expected to be fast and cheap.

3) Its planned to be just nice and comfortable. Nice and fast wallet, easy to setup mine, nice looking blockchain explorer.

4) Guarantee that 1-2-3 always will have a sence. Ever if we'll find vulnerablity in sign alghorythm we could always declare that as depricated and issue the new one with fixes. If we'll have so many transactions that we can't process ever with 3 blockchains - we could add 4,5.. 65535 blockchain and keep transactions fast.

5) Additional services, like fully anonymous decentrelized VPN, audio video streaming, buisness collaboration tools and etc. Thats not related directly to crypto currency itself but thats would be first services that will work with DapCash. So at least you'll have cause to purchase some DapCash at least to use DapVPN, DapConfCall and other service.

Omg, it was really bug with site - was empty on Linux Chromium and MacOS Chrome browser.
Fixed, check it pls.

Yepp, thanks, forgot to mention that I'm on Mac :)

seems like you guys know that you re doing, just checked your website :) http://en.demlabs.net/ourportfolio/
will follow up the project
is it premining happening now?

Website is not available anymore?

Thank you :)
About premining - right now only the test blocks. During the pre-sale we'll share the test blockchain and will start the premining process. Because we've extra hard mining for gold, the curve of complexity will have big rise after beginning to help us with it. Or may be not, if pre-sale will start good we'll rent the cloud service and start to premine immediatly.

Right now is going consensus coding, we have not only PoW tokens but DPoS as well (they'll be anounced later and may be only will be availble on the ICO ).
Also lot of work takes node development, we're planning not only blockchain but another decentralized services. First is smart contracts of cause. Second - DiveVPN, decentralized post-quantum anonymous VPN. And keep ability to add another services later - messanger, audio/video calls, desktop share and etc. Everything as safe as it possible :)

Sorry, we're moving it on another hoster, hold on, soon we'll get it back online. Also tomorrow/aftertomorrow should be masive update and started the open registration.

The idea of a quantum resistant coin is very interesting. Can you hold a bounty company? Better yet, airdrop ;)

Yep, its more than interesting - its nessesary idea. Before the Apocalypse start, we could have another big problem - lot of hardforks in process of replacement classic cryptography to the post-quantum. That spreads capitalization, like Bitcoin Cash, Gold, Diamond and whatever else was forked did with BTC. Only right now is announced about 40 hardforks of Bitcoin. Thats the new trend. Imagine, what happens when the first quantum hijack happens - head currencies became broken on lot of forks, it will be really like apocalypse.

So we must be ready for this. Thats why we've started this project.

Not understand a little about bounty... bugs bounty? Promotion bounty? And what is 'airdrop', new form of drone delievery? :)

Such projects are gaining popularity recently. The problem of quantum computers is of concern to everyone now. I hope that this project will be able to offer its solution.
I would like to see more information, a website and so on.
Good luck to the developers!

Thank you very much. We're planning to open the registration on pre-sale today and upload the new version of white papers before the pre-ICO.

Interesting having 3 types of tokens. I shall follow this project.

Site returned back, soon will be open the registration.
Also is working Telegram group chat for discussions, everybody welcomed! https://t.me/joinchat/AnP30RMItGJciaD92p4fFw

I'm quite curious how this ICO develops in the coming weeks  :)

DapCash DAPG tokens pre-sale started!

Site:  https://dapcash.org
More details on our site https://dapcash.org and Telegram chat  https://t.me/joinchat/AnP30RMItGJciaD92p4fFw

For marketing research we've added 10'000 silver tokens for sale, site is updated. If will be more interest we could presale more silver than gold.
Both tokens are counted in cap.

White papers are published, both English and Russian versions.

Quantum Apocalypse approaching

When ICO started?

ICO we've shelduled at 21 Feb but I'm afraid we'll move that date on 1-10 March.
In anyway pre-sale is already started. You could go to our site and pre-order some coins with discount 30% :)

Pre-sale update:

- DapCash Gold: Reduced price to 0.001 ETH ( 0.0007 ETH wth discounts on pre-sale). All who preordered golden coins got 100x increase of amount in their accounts on our site.

- DapCash Silver:  Reduced price to 0.000001 ETH ( 0.0000007 ETH wth discounts on pre-sale). All who preordered silver coins got 1000x increase of amount in their accounts on our site.

Keep tracking and feel free to contribute us and ask questions, everything is going well. Soon we'll do another massive update on the site, team, code and etc, keep tracking and thank everybody for support and advices.

We have twitter now!

https://twitter.com/DapCash/ (https://twitter.com/DapCash/)

Everything is going well, we met early investors. Possible, pre-sale will be closed ealier than we've planned because all the investments that we need expected to be collected on the next week or so.
Development is moved forward in the node development and UI. Soon we announce Wallet prototype, node prototype, payment RPC and other stuff.

Also updated a little the silver concensus. Its planned now to be based on so-called hierarchical PoW like Zillliqa or another name - blockchain sharding, when no needs to store all the blockchain on all nodes.

Because we have multiple blockchain without consensus limitation, we've decided to keep Golden blockchain as conservative as its present. And use it to make consensus between silver blockchain's shards.

More news in the approaching white papers update, keep tracking us there, in Twitter and Telegram.

Project news in one block:

First, we've renamed DapCash Copper (DAPC) to DapCash Bronze (DAPB). Thats more relevant to its role and assignment. Consensus still Distributed PoS with delagate voting via DapCash Gold blockchain

Second, DapCash golden blockchain became now the basement for all underlaying hierarchical blockchains - Silver, Bronze and may be more.
What it gives? Sharding and delegate voting between shard  to have smaller hot wallets and more decentralization in PoS subcoins.

Third, the silver block time generation rised to 100 second. Exchange between DAPG and DAPS now 1/100 as it was more than week ago. DAPG's price now changed to 0.00007 ETH. All DAPG preorders on our site now are multiplied on the same rate plus 10% bonus #dapcash #cryptocurrency

Fourth, DapCash Bronze would take biggest part of throughput, at least for the first time, until we'll have not so much subcoins.
DPoS gives little more troughput gowth than usual PoS. Thats we'll describe later, stay tuned, we keep pushing that.

With best regards,the DapCash Team.

My apologizes, unintentionally locked the thread :)

News updates:

 - We have updated the design of the site, removed all unnecessary visual effects and made the page light, so you can easily read and perceive information.
In the coming days we will add a section on news about the quantum world, a blog about the features of post-quantum crypto currency technology, as well as a section with the most popular questions that you ask and our answers to them

 - Extended the team. New memebers - Yaroslav Lunev, ICO consultatnt. Maxim Krasylnikov - frontend developer.

 - Updated the github - new code for graphical wallet, some fixes in libdap, new API for configs, basement for node itself.

 - Did interview on Satoshi.fm https://anchor.fm/satoshifm/episodes/1674ed0 (https://anchor.fm/satoshifm/episodes/1674ed0)  about DapCash, Quantum Apocalypse and etc. On Russian.


Stay tuned and look forward for next updates.

Public pre-sale continues, till the end of the March.

Hurry up, 30% discount is still actual till the end of the February only.

DapCash Gold and DapCash Silver are available on our site https://dapcash.org (https://dapcash.org)

Prices:

1 DAPG =        0.0001 0.00007 ETH
1 DAPS = 0.000001 0.0000007 ETH

How can I see the number of coins i`ve purchased in my account on the website?

And why is the "my account" page from your website half in english and half in russian?

You can see the purchased coins in the section "My coins" in your account on the site.
What exactly is in the "My account" in Russian? Let us know and we will fix it. Please make a screenshot of the page with the Russian language and send it to me in pm

so, is it fake call?
Or any reliable source?

There is nothing fake here.
What you mean by a reliable source is unknown to me.

I'm trying to send you a private message, but I can not. Please check the message settings on your profile

This people are amazing. They answer straight away.

@ascatelluma:

Thanks alot for answers. It helped find my coins.

Regarding the part with the russian language I was refering to the wordpress section of the site: https://dapcash.org/wp-admin/
I dont know why i taught i will find my coins there :)

@fraidycat19 Bug fixed, now you can not get to this page.

If our user dissatisfied with something, this allows us to increase the usability of the product. We constantly change and do not stand still  :)

It will be nice if you post the progress of the raised amount so far.

Will definitely buy some more when the ICO begins.

ATTENTION!!!
If you recieve a personal message from person out of our member's list and this person says smth as DapCash team's member, offers bonuses, asks about your personal data - please blacklist them and report us about them, these are scammers and possible fraud.

We've raised about 10 ETH for now,~2% of total sum. Not big but more important that we found investors, - so R&D and promo we found who will fund. So, pre-sale is now going just for currency population... and just for people thats want to invest some.
More information about investors, advicers and roadmap updates we'll publish when all the papers will be signed, I hope it happens on this week but you know it could take some time. Important moment - its became more clean with marketplace, we met specialists that helps us.

DapCash is going to became really serious buisness, we have to prepare really exciting ICO.

what is all the information presented by the project? for example, can you verify that the person listed as a team member actually supports this project?

After some extensive research I finally settled to buy tokens. I plan to let them sit for a year or two. Of course I am aware it could end all in a total loss, but a loss of a hundred bucks will not - thank God - let me go hungry and if the prices rises maybe I make some serious money. Isn't that the reason we come to a place like this in the first place?

You can see in the github that the team members are support in DapCash.
In addition to programmers, there are two people. I'm a manager and Yaroslav is a consultant. All these people are listed as team members. You can ask each of them, if you wish.
The people we hire, but who did not make a labor contribution to the project - are not listed as team members on the site.

We have big changes:
 - We move release to December and pre-sales till August.
 - With current pre-sale speed we should rise about 10-50% of hard cap
 - Till the August we'll work with another project Kelvin that will be based on current DapCash code. After August DapCash will be restarted based on the Kelvin code
 - On the Kelvin project Demlabs should rise all the funds that we need.
 - DapCash ICO also will be on the Kelvin platform. That makes all the things easier because we don't fit ERC20
 - DapCash and Kelvin will have little different set of technologies, mostly related with services - tor-like VPN looks goes in DapCash, smart contracts exactly in Kelvin.
 - Exchange between DapCash pre-orders and Kelvin tokens would be able at August-September, after Kelvin release.
 - Refund requests are guaranteed to be executed.

That's all should give us guarantee that we collect investments, and run DapCash, current estimate for DapCash is 21 December 2018. Also it keeps the project independent - we'll earn funds for DapCash with the Kelvin project.

About pre-sale, it will be longed till the August. Only discounts will be lesser from 1st March, we don't need to collect monies quickly to start now - we have some funds for beginning, all the rest we could rise slowly. so at March pre-sale discount will be lowered to 20% at May became 10%.

All DapCash holders just recieved +10% loyality bonus. Its actual only for holders who waits till release that is planned at Oct-Dec 2018. Bonus burns out if you request the refund.

Nice going. But what is Kelvin?

Hi dev. how to mine this coin?

In progress. Kelvin its not independet project, thats supported by advicers and investors.

Today was first public presentation of Kelvin/DapCash technologies on Quantum Technologies Conference at Moscow.

Soon should be the site, whitepares are in progress

Best way we expect to do that in cloud. Or collect old smartphones, ming is CPU optimized.

There is idea to make "rat miner" - collect dead smartphones, sold out CPU's and place them on special board for only mining, nothing else. That should be cheapest way to mine the DapCash coins.

There are not much information about this project. Can you please give u
More detailed information about this project please?

It looks like there is still much less understand this project and we also want more information on the projects so that we can follow this project with more gusto.

looking for a new project and it find me interested that i wanted to follow it,in hoping that will run it through,update us more better great news,thanks team

Yes. This week we're planning lot of information and announces, keep tracking

New project has Telegram group: https://t.me/kelvinblockchain (https://t.me/kelvinblockchain) and simple landing site htts://kelvin.foundation (http://htts://kelvin.foundation)

More news about DapCash would be soon, same for Kelvin.

EN We are happy to announce our website https://dapcash.org/ in Russian language. Currently you can choose the language in the top right corner of home page.

Science TV has talked to Dmitry Gerasimov, a blockchain and information security specialist, the author and co-founder of Kelvin and DapCash projects, Demlabs, about what post-quantum cryptography is and how secure it is to use blockchain in general. https://dapcash.org/interview-en

It can be a big project. With the hope for investment... :D :D

Why with hope? There are investments, everything works perfectly

Why are quantum computers dangerous?
Read about this in our new article https://dapcash.org/quantum-apocalypse-en

a good idea a very interesting project, I hope many buy tokens. hi dev how much tokens price in pre sale and public sale? Are there any bonuses in each period?

Hi. When are tokens going to be issued?

Hello. Before, I was not interested in agriculture, but now I want to try. Can your specialists consult me?

Price of tokens:
1 DAPG = 0.0001 ETH
1 DAPS = 0.000001 ETH
Now 20% discount on tokens
In May, the discount will be 10%
Tokens will be issued in the Q4 2018

Of course, we can talk about agriculture and any other fields of activity that are not related to programming, but I advise you to find the person who understands this field.

Fantastic idea on this project, success in your full implementation.

This sector is a rather promising business area.
it is popular in many countries around the world.
and to accept such activity before crying - is a very good idea.

looking for a new project and it find me interested that i wanted to follow it,in hoping that will run it through,update us more better great news,thanks team

The first test launch of the post-quantum VPN took place today

We have split repositories of DapCash and Kelvin

🔥 We are pleased to inform you about some changes that have occurred in our project.
👭 Now, the repositories of DapCash and Kelvin are stored separately.
⭐️ Links to repositories of both projects you can find on our website on the “docs” page: https://gitlab.com/demlabs and https://github.com/kelvinblockchain.
We have done this because of difficulties in the use of Microsoft software. We hope that these changes will make acquaintance with the projects easier and more convenient.

I think a lot of people will be interested in this project.

We promised to tell you what new and interesting things would appear in our project. Here they are.

https://dapcash.org/dapcash-updates/

Thank you for the update.

Let's head into the algorithms of symmetric encryption. Simple and easy to understand.

https://dapcash.org/symmetric-encryption-algorithms/

We have done the load testing of DAP platform!
Want to know what we did and what results we got? Read our brief report on the test results.

https://dapcash.org/dap-load-testing/

Dear community!

We are pleased to announce the exact dates of DapCash ICO:
Start - November 23, 2018.
End - December 24, 2018.
Before the start of the ICO, you still have the opportunity to buy DapCash coins with 10% discount!
ICO will take place on the Kelvin Blockchain platform inside the private shard of DapCash. This way to carry out the ICO will allow you to activate the main functions of the tokens immediately after their purchase.
The withdrawal of tokens during the ICO will be restricted. Also, some restrictions will be applied to tokens within six months after the ICO. We will notify you about all the restrictions in advance.
After the test period, the DapCash blockchain will operate in the full-scale regime.

Hello,

Can you give us some details about the prices of the coins in the ICO?
Also I get timeout when i try to login to dapcash website...

Cheers.

I have flip through the website of this project and so far i think i like what i read about Dapcash, although i get a bit confused with the 3 different type of coin available and their various functionalities, i think i will invest a little.

Here we are talking about Asymmetric algorithm RSA.

A series of articles understandable even to non-specialists.

https://dapcash.org/the-asymmetric-algorithm-rsa/

Bought some during pre-sale but cant login. I get ERR_CONNECTION_TIMED_OUT from this page: https://dapcash.org/login/

In the anonymity requirement, will DapCash use the protocol or network Tor in the transactions? Is the mining exclusive to the CPU?

Temporary network error. Check again please

I learned about DapCash. This is a project that focuses specifically on anonymity and transaction speed. But I think you need to pay attention to marketing. 13% for marketing is a significant figure, but the efficiency and implementation need to review!

Completely bamboozled here.
So you've got two projects on your site; DapCash and Kelvin and they both address quantum computing problems on the blockchain. However, one is casual and the other hardcore? How do they communicate? Is there any interoperability?
And then, you have all these coins - Gold, Silver, Bronze.
This is not something one can just casually glance at to get into  :'(

Can I buy only a bronze coin or do I need to buy each of them: gold, silver and bronze?

Could you explain what is the difference between common strong computer and quantum one in numbers?

When can I start mining?

Please, tell me, how are you going to protect other blockchains? Coz you create your own one, nothing about protecting Bitcoin and other ones

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

what will happen after live-coin period?

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.

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

Is this project still runing?

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.
