1  Alternate cryptocurrencies / Altcoin Discussion / [ANN][DTC][XPM][PTS] A small Linux Live System for mining DTC, other CPU coins on: January 27, 2014, 01:53:24 PM
I just noticed that on reddit, so want to share with the forum community

Hash: SHA512

[ANN][LINUXLIVEISO][XPM][PTS] MinerAgent 1.4 - A small Linux Live System (amd64) for [remote] mining of CryptoCurrency (iso image, bootable)

I would like to announce the a new release of MinerAgent.
Version 1.4 adds jhPrimeminer-Aero by clintar DTC datacoin examples and DHCP autoconfiguaration
It shaves off a few unneeded libraries to come in at 99 MB

MinerAgent is a small [~100MB] (Linux) Debian Live iso, preconfigured for mining Primecoin and Protoshares with all needed libraries, sshd, perl, python, fail2ban, htop, screen & tmux.
It includes xolokrams primeminer/ptsminer & jh000 jhprimeminer/jhprotominer and jhprimeminer-aero, with some Debian Live script configurations.
It uses Debian sid (Linux 3.12; libboost-1.54; openssl-1.0.1f; libgmp-5.1.3; libdb-6.0; libc-2.17)

This iso should boot on any modern 64 bit PC or server and provide quick access to beeeeer rpool ypool xrampool and gpool pools with XPM PTS DTC Primecoin ProtoShare Datacoin mining. ****
This should work with any XPM or PTS pool that supports direct submission of payout addresses with either xolokrams or jh miners.
It is planned that this environment will have more CryptoCurrency support in future. Suggestions are requested.

To use: Insert into computer, or connect .iso to lights out or remote access console. Boot from disk or iso.
Please change your password!

mine with the following commands. you can use putty under windows, or ssh under unix to copy-paste.

- --------------------------------------------------------------------------------------------------------------------------------

This Linux Live system requires no local storage and has no persistence. Passwords and any local configurations will be lost on reboot.
It is recommended that any local configurations be stored on a remote persistent store accessed via scp/ssh.
No "CryptoCurrency" exists in this iso, nor does it exist in the mining environment once booted. A miner submits shares on behalf of your payout address.

Miners included have been signed with MinerAgent public key. These miners were compiled from author or fork maintainer git repos with no modifications to the source.
Always be careful with unknown miner binaries. Malicious miners have been discovered in the wild!

Comments, Improvements, Feature Requests and Constructive Criticisms would be appreciated. (0xBF8A2DC7) pub.asc 3.13 KB (3203 bytes)

5  Alternate cryptocurrencies / Altcoin Discussion / [DTC] Someone tried to gain control over Datacoin, but he failed on: December 21, 2013, 07:30:45 PM
Hi community,

I want to tell you a story about hacking Datacoin mail and twitter account.

All began when I received message from our promoter who works with Twitter: 'I cannot log in, incorrect password!'
I own, so only I can reset the password. 'Strange', I thought.
Then promoter told me: 'someone posted address with invalid BTC\DTC donations wallet!' You understand: Twitter account was hacked.
I tried to recover password, but nothing helped: I simply couldn't receive mail from Twitter. All my messages to their support also stayed unanswered.
I waited for some time - sometimes it takes time to receive mail from Twitter. Soon I noticed tweet in hacked account: "#datacoin is looking for developers and anyone interested in helping us continue to grow. Contact"
WOW, it was not ordinary hacker attack - someone has plans to gain control over Datacoin!
In some minutes I got new mail to : someone asked me about yesterday's mail regarding re-design of the site. After some conversation I understood that I didn't write any mails to this man yesterday.
Yes, you got it right: was also hacked, and there were filters for many addresses, twitter support was among them. Also I saw unusual activity for it.

Now I changed all passwords, enabled 2fa everywhere (hackers didn't got password to other mails, otherwise they could take full control over

I want to sum up and tell you 2 things:

1. ALWAYS enable 2fa everywhere.
2. Datacoin seems very attractive to many of us, and someone wants to control it. Be aware!

As I see, Cryptsy added many coins, most of them don't have so big community and unique technical features like Datacoin. They dind't fix their issues (I'm still waiting for deposits to be showed even in 'pending'), but they are adding new coins. Well, let's try to get DTC on Cryptsy one more time (though I cannot understand why they add BET, UNO and especially ORB , but don't add Datacoin )

9  Alternate cryptocurrencies / Altcoin Discussion / [DTC] Thanks for those who sell Datacoin at 0.001 on: December 16, 2013, 10:21:39 AM
Hey people, I received many mails from investors last days, and there were a lot of thanks for those who sells large amounts of DTC at .001  price. I also bought some more DTC at these ridiculous price this night (EU time) when someone dumped near 25000 DTC during some hours. Thank you from me and Datacoin investors! Stay tuned with our latest news - many of them to come this week Smiley
10  Alternate cryptocurrencies / Altcoin Discussion / [DTC] First Document Officially Uploaded to Datacoin! on: December 14, 2013, 01:52:14 PM
Hi community,

I did this only as proof-of-concept. The first document officially uploaded into Datacoin is quote from Fahrenheit_451 by R. Bradbury.
The book is about censorship and the destruction of knowledge, two things Datacoin will fight with his permanent and decentralised storage.
Why quote? The book is under copyright, so I don't want to break the law with such first document.

TX ID is 7a5df5718d96c149257650caf38b1b987a2696344cd368f4b6fa4b6ef42b09a9

You can check it on or encrypt it from

And I want you to choose books that are not under copyright from here:  and post them in the thread.
Books like Bible are also welcome, but remember: now 'big file' functionality is in development, so just now I can upload bigger books that are archived and split into chunks. Books that are <128KB in zipped state are the best choice! Wink

Some suggestions from another thread:

I agree. I think free (copyright expired) ebooks should be stored early on. I would donate 10 DTC to the unofficial team if someone took it up.
Candidates (bzip compressed 50-200 KB / book):
Moby Dick:
Alice's Adventures in Wonderland:
Les Misιrables:

And I'll also donate DTC for storing such books .

15  Alternate cryptocurrencies / Altcoin Discussion / [DTC] Datacoin Foundation on: December 10, 2013, 07:16:46 AM
Hi community,

Datacoin Foundation starts here.
Datacoin has great potential, but now it is too small. We need more services based on 'storage' feature, we need promotion, exchanges, DTC as payment methods. We need to pay developers and promoters, stores and exchanges, VPS providers and economists for their work.
We have some DTC on our first donations wallet, but interest to DTC is very high, so we need many coins to reward all for their work. Today I'm starting this foundation.
All our spending history will be transparent and listed both here and in appropriate thread.

17  Alternate cryptocurrencies / Altcoin Discussion / [Datacoin] External miner released! on: December 09, 2013, 09:41:00 AM
Hi community,

I'm glad to say that mumus released his version of jhPrimeminer there:
Quote from: mumus
Yes, the hg5fm is my repo and of course you can use the miner and the code freely.

MrMagic gave us this link and additional info about mining:

Quote from: MrMagic
The only changes I had to make were adding transaction.h and transaction.cpp to the project and setting useGetBlockTemplate = false. I compiled using x64-AVX in Visual Studio 2012 Express.

To start mining you need to open the debug console on your server wallet and put "setgenerate true 0". Now you can point your miner at the wallet and start mining.

I tested on testnet with a few PCs and watched the mined blocks roll in. I have been running on mainnet on all my PCs for about 24 hours and I mined one block so far.

So now you don't need to have separate wallet on each mining machine, and it is big step ahead to getting pools up and running! Many thanks to Mumus!

Datacoin FAQ

1. What is Datacoin?
Datacoin is both a reliable and decentralized data storage service and a currency to pay for this service.

2. Where my files are actually stored in Datacoin network?
Files are stored on local HDDs of all users participating in the Datacoin network. Each user has it's own full local copy of all Datacoin files.

3. Are my files encrypted in Datacoin?
No. You are responsible to encrypt your files before sending.

4. Is there any way to delete my data from Datacoin blockchain?
No. Once data goes into Datacoin blockchain there is no way to delete this data.

5. Why Datacoin doesn't handle file names and any other details about my files?
Datacoin daemon works with blobs only. This is because it must be a reliable software. Any additional metadata must be strictly verified and this code can lead to bugs. Bugs are bad. But no special rules are required for blobs except of size verification.

There is a upper level protocol (Datacoin envelope) that handles file name, files bigger than 128Kb, file updates and compression. You can follow Datacoin envelope development here:

Datacoin envelope doesn't need any modification in Datacoin daemon and Qt wallet - JSON RPC connection is enough.
6. How much disk space does it take?
1Mb (max block size) * 60 minutes * 24 hours * 365 days = no more than 513Gb per 1 year

7. Is this storage free for storing data?
No. Currently fee is 0.05 DTC per 1Kb of data. This standard fee can be changed in future without hardfork.

8. Sender pays fee and who gets this fee?
All fee goes to miners i.e. fee is distributed between nodes supporting Datacoin network proportionally to their mining power.

Fee from fully loaded block is about 50DTC (block reward now is ~11DTC and it decreases).

9. Does the whole concept mean that it is tough to go for Android or IPhone client?
Mobile clients need light wallets in order to see balance and send transactions. Light wallet will interact to some web service instead of storing full blockchain locally.

10. People really need to store more than 513Gb of data per year in decentralized storage. Do you have any plans to increase storage space?
Datacoin is a root storage engine in the decentralized storage service. This storage is both reliable and expensive. I'm now working on concept of personal chains. Personal chains will start from root Datacoin blockchain and will be replicated to nodes by subscription (nodes can choose chains they subscribe to). Datacoin blockchain will handle only identification and some metadata for all personal chains.

Important notes:
- This (personal chains) is only on conceptual level now and will be clarified and prototyped in few months.
- This doesn't mean Datacoin hardfork. Personal chains will be constructed on top of Datacoin network.

11. What is current state of Datacoin project?
Datacoin network [reliable and expensive blob storage in blockchain] - up and running
Datacoin envelope [file storage in blockchain] - under development (Perl prototyping)
Personal chains [more data outside of blockchain] - on conceptual level

12. Who is working on Datacoin project?
oocook5u working alone at network for now. He didn't accepted yet anybody into development team but he plans to do this in the future in order to make process more sustainable. There is unofficial Datacoin team listed here:
This team doesn't work with Datacoin network directly, but developing tools, application for the platform, supporting and promoting Datacoin.

13. What about coins per year, actual block reward and total number of coins?
Coins number is limited to 2 billions. Anyway, current block reward is near 10 DTC per block, what is equal to ~5M Datacoin per year, and this block reward is getting lower when difficulty increaseas. So this limit can be reached only after hundreds of years.

19  Local / Альтернативные криптовалюты / Datacoin - информационная ветка on: December 03, 2013, 06:53:00 PM

Всем привет,

Я представляю криптовалюту Datacoin, которая существует уже третью неделю, и за это время успела себя неплохо зарекомендовать.

Ниже я приведу общую концепцию (компиляцию из оригинального FAQ + статья с хабра + выдержки из многочисленных тредов в ветке форков)
И, для затравки – промо-баннер!  Smiley

1. Что такое Datacoin?
Datacoin – это надёжный и децентрализованный сервис хранения данных, и в то же время – валюта для расчёта за этот сервис

2. Где на самом деле сохраняются мои файлы в сети Datacoin?
Файлы сохраняются на локальных HDD всех пользователей, подключённых к сети Datacoin. У каждого пользователя есть полная версия всех файлов Datacoin (см. вопрос 10)

3. Шифруются ли мои файлы в Datacoin автоматически?
Нет. Вы сами можете зашифровать файлы перед отправкой в Datacoin.

4. Есть ли возможность удалить данные из БД блоков?
Нет. После попадания данных в сеть Datacoin они там сохраняются навсегда.

5. Почему Datacoin не обрабатывает имена файлов и другие их параметры?
Datacoin технически работает только с BLOBs, бинарными объектами. Это сделано для надёжности сервиса. Любые дополнительные метаданные должны строго проверяться, что может привести к багам и уязвимостям.
На данный момент в доработке находится протокол высокого уровня (оболочка для Datacoin), которая обрабатывает имена файлов, файлы больше 128 КБ, обновления файлов и сжатие. Вы можете следить за разработкой данной оболочки здесь:

6. Сколько места на диске может занимать база блоков Datacoin?
1Mb (максимальный размер блока) * 60 минут * 24 часа * 365 днй = не более 513Gb за год

7. Бесплатно ли это хранилище?
Сохранение данных – платная операция. Текущий налог составляет 0.05 DTC за 1 килобайт. Эта комиссия может быть изменена в будущем без хардфорка.

8. Отправитель платит комиссию, но кто же её получает?
Все комиссии идут майнерам, т.е. комиссия распределяется между узлами сети пропорционально их мощности
Комиссия от полностью заполненного блока составляет около 50 DTC (награда за блок сейчас немного выше 10 DTC).

9. Означает ли концепция «большой базы данных блоков» невозможность портирования на мобильные устройства?
Для мобильных клиентов будут разработаны «лёгкие кошельки» с возможностью просматривать баланс и отправлять транзакции, без необходимости загружать всю БД блоков.

10. Людям на самом деле требуется сохранять более 513ГБ в год в децентрализованном хранилище. Есть ли у вас планы по увеличению размера хранилища?
Datacoin – это корневой движок хранилища в распределённом сервиса хранения информации. Хранилище это является надёжным и дорогим. Разработчик на данный момент работает над концепцией «персональных цепочек», которые будут начинаться в корневой цепочке Datacoin и будет распространяться по узлам сети с помощью подписки (узлы смогут выбирать, на кого подписываться). Корневая база данных будет содержать только идентификаторы и метаданные

Важные замечания:
 - «Персональные цепочки» на данный момент находятся на концептуальном уровне, это будет уточнено и реализовано в ближайшие месяцы
 - это не потребует хардфорка Datacoin. Персональные цепочки будут работать поверх протокола сети Datacoin

11. Каково состояние проекта Datacoin в текущий момент?
 - Сеть Datacoin – работает в настоящий момент, стабилизация сети прошла успешно,
Оболочка для сохранения файлов в Datacoin – в разработке (на данный момент доступны консольные команды для сохранения)
Персональные цепочки – на концептуальном уровне

12. Кто работает над Datacoin?
В данный момент единственным официальным разработчиком является член форума oocook5u. Существует также «неофициальная команда», а также несколько сторонних разработчиков, создающих внешние инструменты, дизайн, рекламу и приложения на базе Datacoin.

Чуточку  технических данных:
- Ко всем транзакциям добавлено поле бинарных данных. Размер поля жёстко ограничен 128КБ, размер блока – 1МБ.
 unsigned int nLockTime;
+    std::vector<unsigned char> data;

 - Добавлен метод RPC – senddata: он создаёт транзакцию с данными. Пример ниже показывает, как сохранить файл, сжатый bzip2, в базе данных блоков. Методу senddata необходимо передавать данные, закодированные в base64. В случае успеха метод возвращает TX ID.
bzip2 -c -9 filename.txt | base64 -w 0 | xargs -I XX datacoind senddata XX

-   RPC метод getdata будет добавлен позже. Нижеследующая команда может получить данные из цепи блоков без специального RPC метода
datacoind getrawtransaction TXID | xargs -I XX datacoind decoderawtransaction XX | grep -E '"data"' | grep -E -o ': ".*"' | sed -E 's/[": ]//g' | base64 -d | bzip2 -d > filename2.txt

Несколько интересных идей с форума о применении такого хранилища.

1. Хранение зашифрованной информации (в т.ч. личной) в виде «открытый ключ — зашифрованная информация», уже есть простейший скрипт для кодирования\декодирования файлов таким образом. Такой информацией может быть не только «записка на память», но и некие данные с критичным временем первого появления в сети. К примеру, при необходимости доказать авторство научного открытия можно будет указать: вот база хэшей, вот моя информация об открытии, вот время её сохранения. Редактировать и подделать данные невозможно, следовательно, это может служить доказательством.
Кстати, таким образом можно хранить, к примеру, тот же зашифрованный биткоин-кошелёк, и он не может быть случайно удалён из googledrive-аккаунта. Этакий аналог банковской ячейки.

2. В перспективе вероятно использование такой БД как вспомогательного хранилища для «анонимного твиттера»: вам не нужно проходить процедуру регистрации в таком «твиттере», не нужно «светить» свои личные данные и прочее, вам достаточно лишь отправить транзакцию с данными в определённом формате, и они отобразятся на сайте. Естественно, в этом случае можно будет лимитировать размер данных для таких сообщений, как сделано в оригинальном твиттере.

3. Создание сайта, на котором можно предлагать общественно важные файлы для сохранения, а также делать пожертвования для этого (те же дампы The Pirate Bay, Wikileaks, etc). В случае нижеописанного сценария большие файлы (порядка 100МБ и более) , которые требуют значительных денежных средств, могут быть сохранены с помощью сообщества. Также никто не сможет забрать кошелёк с большим количеством пожертвованных монет.
 - каждый файл содержит кошелёк для пожертвований. Каждый файл заливается на сервер и разрезается на много мелких кусочков (пусть 1 МБ)
 - Любой может отправить монеты на кошелёк выбранного файла. Когда на кошельке хватает средств для отправки кусочка, процесс загрузки начинается автоматически
 -  Страницы сайта содержат «прогресс-бар» для оставшейся части файла, оставшегося объёма пожертвований и т.д.
 - Если кто-то отправляет большой объём монет для пожертвования, кусочки для загрузки становятся в очередь
 - Будет существовать лимит на количество кусочков файлов в день, чтобы не допустить перегрузку сети одним ресурсом.

Наш сайт: (дизайн главной страницы доработан, остальные страницы тоже будут скоро приведены к такому виду)
На нём размещено ещё много полезной информации.
