The prizes are distributed to those who are the first to submit the idea. The prize is paid only for non typical ideas, which have an element of uniqueness and novelty.
 
The contest is open for a period of 1 month. The contest will close on April 30th or when the number of received ideas reaches 1000.
 
The contest judges are picked by the Fund and comments and feedback will be published along with references to the transactions which contained the prizes.
 
Prizes:
 
5000 EMC – Total prize pool

500 EMC – Prize for ideas which have been accepted for execution (the prize is paid out the moment the decision to execute the idea is made by the committee. Decisions to execute on ideas may take place during or right after the content closes)

50 EMC – Prize for an idea judged as potentially interesting for future implementation (the prize is paid when the contest closes, please don't forget to include your wallet addresses)

10 EMC – Prize for an idea that shows the contestants "best effort"  (the prize is paid when the contest closes, please don't forget to include your wallet addresses).

10 EMC – Incentive prize, paid for placing a link to this very content thread in your group, blog, forum, facebook, twitter or anywhere else that will be seen in the cryptosphere. Paid once for each linked resource, assuming the referrer proposes at least one relevant idea (as determined by the committee). The more you share and promote the contest itself, the more EMC you earn!

 
The prize pool will be distributed regardless of the number of ideas received. Example: If we receive 10 ideas total then each submitted idea will receive 500 EMC
 
Criteria such as the quality and feasibility of the idea remain at the sole discretion of the committee. Winning ideas are considered as those which require minimal investment, greatest potential, low implementation costs and a high probability of success.

Ideas which are variations of each other, or improvements upon existing ideas shall be treated as a single idea.

The contest does not accept ideas on wallet modifications or new functions for installation of Emercoin systems. Emercoin developers have a great  number of innovations, some of which will be put into practice in the next wallet release. Nevertheless, the fund is not participating directly in Emercoin development. If you have ideas on Emercoin wallet improvements, please, email us at:team@emercoin.com.

[децентрализованное доверенное хранилище]

Предлагается масштабируемая инфраструктура для беспарольной авторизации на неограниченное число независимых серверов сети.

Инфраструктура базируется на блокчейне криптовалюты, используя последний как децентрализованное доверенное хранилище хеш-сумм клиентских SSL-сертификатов. Сами сертификаты могут быть сгенерированы клиентами локально, без участия каких-либо внешних сервисов авторизации, и быстро заменены по мере необходимости, что делает эффективными как плановую замену, так и быстрый отзыв скомпрометированных сертификатов.

Также предложена система InfoCard — децентрализованных распределённых «визитных карточек», с возможностью организации информации в иерархическую структуру, что может быть полезным для быстрого обновления содержимого карточек членов компаний или других организаций.

Совместное использование предложенных сервисов позволяет быстро, буквально в один клик, создавать и обновлять учётные записи, а также иметь беспарольный логин и защищённое соединение с неограниченным множеством серверов.

Новизна предложения заключается в полной децентрализации системы, то есть отсутствия некой группы серверов авторизации под единым управлением, что имеет место в системах Kerberos, OpenID, TeddyID и им подобных. В результате, становится невозможным блокировка пользователя посредством административного ресурса, или же одномоментного отказа в обслуживании всей системы авторизации из-за технических сбоев или злонамеренных атак на серверы авторизации.

Preliminary registration is now open for domain records in the domain zones "*.coin" and "*.emc".

Сlick here for details - http://emercoin.com/.COIN_domains_FOR_FREE

[*.coin]

Currently we have started preliminary registration of domain records in domain zones “*.coin” and “*.emc”.

So, if you wish to pre-register your domain(s), please send the request to domain@emercoin.com for preliminary registration. The request should contain domain names(s), and EMC-address to which we could transfer ownership. The ownership address can be any EMC-address from your wallet program.

We reserve right to deny any request if consider it to be squatting or malicious action. Any email from public e-mail services (gmail.com, homail.com, yahoo.com etc) will not be honored.

Pretty soon, in the mid of October, we are going to release new version of EmerCoin wallet 0.3.0. The new version will contain an important improvement, the fundamentally new infrastructure subsystem - Name-Value Storage. The subsystem will provide bunch of services (watch further updates), including distributed DNS, like it is implemented in NameCoin, but with more advanced features.

The ownership will be transferred in 1 week since new version of wallet will be released. After official release anyone will be able to register domain(s).

Initial domain registration will be free, and issued for 120 days.

For the first time in the history of cryptocurrencies, is used STUN protocol to obtaining an external IP address, instead of WEB-service.

  This problem is already discussed in the cryptocurrency community, for example, here:
http://www.reddit.com/r/Bitcoin/comments/29zx7z/bitcoin_core_uses_showmyip_as_a_centralized_hard/

But, without any positive outcome.

Problem description:

  Bitcoin and it’s descendants (PPC, QRK, etc) – all of them uses same public WEB-server for obtain external IP.
There is two public servers, hardcoded into a wallet program:
- http://checkip.dyndns.org
- http://www.showmyip.com

For source code, see https://github.com/bitcoin/bitcoin/blob/master/src/net.cpp, function GetMyExternalIP()

  What is interesting: 2nd server http://www.showmyip.com is out of service nowadays. So, all Bitcoin and altcoin networks currently
dependent  on single WEB-server: checkip.dyndns.org. If this server will gone, then coin network will not died, but dramatically lost stability.
This will happening, because of peers wouldn't able to advertise  (represent) another peers into network, and peer network
connectivity will be decreased.

  Moreover, current WEB-mechanism for obtain external IP is based on non-standardized human-oriented text protocol.
Therefore, if site owners will modify output format, (for instance, for better reading), then all coin wallets will be unable
to parse and understand answers, and results will be as same as server down.

  In addition, dyndnd.org’s owners able to analyze WEB-server logs, and collect list of IP addresses, where is running coin wallets
and request timestamps, if is not doing this right now (request signature is hardcoded and well known, and easy to distinct).
If we remember, users usually runs wallet just before start some transactions, then we aware:
analyst can correlate wallet start and transaction time, and link it to IP address.
This is serious compromise of coin users anonymity.

Our solution:

  We substituted current non-standard, hard-weight (based on TCP/HTTP) protocol to protocol, based on mature standard RFC3489 (STUN),
designed especially for this purpose. See: http://en.wikipedia.org/wiki/STUN . This is lightweight, UDP-based protocol, used in SIP-based
applications (VOIP, IP-video) for 10+ years. And since it is standardized, we can use unlimited list of  servers for request, and always be
sure: EmerCoin wallet can parse/understand answer from anyone.

  Currently, new EMC-wallet for obtain IP address uses 47 STUN-servers, distributed worldwide, and request sequence is random. Therefore,
nobody can collect significant list if our wallets. Moreover, we performed some steps for randomize signature request, and for server is difficulty
to distinct EMC-wallet request from request, sent by IP phone or softswitch.

Therefore, we reached our goals: removed dependency from centralized server, increased network stability and provide real  anonymity.

EmerCoin team.

Если вы желаете введение PPCoina на MtGox - голосуйте!

[каждом]

Пул раздаёт участникам текущий блок и ожидает получения шар. Как только один из участников присылает шару, которая оказывается меньше текущей цели, пул объявляет о генерации подписи блока. Приз за генерацию блока распределяется между участниками, владелец пула берёт себе некоторую долю.

Но для конкретной сети, например Битконин, в данный момент времени этот "текущий блок" одинаков для всех участников?
Если да, то вырисовывается интересный вариант.

Допустим мы изменили программу майнера таким образом, что она получает текущий блок от одного пула, а рассылает решения нескольким. Решение корректное, даром что бесполезное, все пулы зачитывают шару. А когда блок будет найден, вознаграждают такого хитреца на каждом пуле за участие в раунде!

Или даже так, пропускать транзитом все шары через Соло режим, а дальше - пулам. Если повезет найти решение блока, вознаграждение останется в своем кошельке, а пулам никогда ничего не достанется, только оплата за участие в раундах.

Что скажете?

[Warning!]

Warning! ppc.fixx.ru domain pool temporarily changed to ppc.emercoin.com
Accordingly, change the settings miners!


Greetings!

Pool for PeerCoin: ppc.fixx.ru

0% - fee

0% fee, vardiff.

Extended statistics for each block, for example: http://ppc.fixx.ru/report?blockNum=92334

Now everyone can see who is where and how much. No shares, no one of PPC is not lost - crystal clarity.

The system of payments PPLNS. Importantly, no PPS! (So ​​far)

We did a quick payouts!
Only 6 confirmations (instead of 520!) And a pool adds your balance!


Current speed ~ 20 000 Gh / s

Cloud hosting, DDOS Steady
Working on introducing a Stratum.

How to connect?

For CGminer:

cgminer-o ppc.fixx.ru: 8437 -O UserName.1:x
cgminer-o ppc.fixx.ru: 3333 -O UserName.1:x



For GUIminer:

host: ppc.fixx.ru
port: 3333 or 8437
user: UserName.1
pass: Password (default - x )

If you have questions or suggestions, post them here or on the support@fixx.ru, will try to solve quickly.

Attention beginners! The system PPNLS, does not pay the fee for every ball, as in PPS (Pay Per Share). While the pool of young and there was little power rounds durable and profit can take a few days. In fact, in the beginning, it Mining in Solo mode. But as new participants, rounds will be shorter, and the regular and predictable income.

[Мы установили Statum протокол. Сложность шар = 8. Настройки майнеров прежние.]

Приветствую!

Мы установили Statum протокол. Сложность шар = 8. Настройки майнеров прежние.

Заметил, что работающих пулов для PPC практически нет, Coinotron фактически стал монополистом. Ситуация на мой взгляд неправильная.
Поэтому мы решили создать новый пул для PPCoin:  ppc.fixx.ru
Комиссия 0% - продлевается еще на два месяца! Возможно и останется нулевая, если будет достаточно сознательных участников, которые настроят добровольные взносы для пула (Donation % в My Account)

Система выплат PPLNS. Важно! не путайте с PPS (где оплата за каждую шару производится моментально)


PPLNS - платит когда пулом найден блок и он подтвержден сетью (520 для PPCoin). В отличие от пропорциональной системы выплат, PPLNS делает невыгодным пулхопперство, но поощряет постоянных, расчетливых майнеров.
Параметр N = 125 000 шар

Пока перевел туда все свои мощности, чтоб пул не был одиноким ~7.5 Gh/s
Хостинг облачный, DDOS Устойчивый
Пул работает через протокол Stratum.
Быстрые выплаты - после 6 подтверждений найденного блока (вместо 520)

Как подключиться?

1. Зарегистрироваться на пуле
2. Скачать клиент-кошелек для получения PPCoin
3. Скачать программу майнер для добычи монет

Для CGminera (последняя версия https://bitcointalk.org/index.php?topic=28402.0): командная строка

cgminer  -o ppc.fixx.ru:8437 -O UserName.1:Password
cgminer -о 170531-4.vm.clodoserver.ru:8437 -O UserName.1:Password - запасной вариант

создать start.txt, вбить строку, переименовать в start.bat


Для GUIminera (последняя версия https://bitcointalk.org/?topic=3878.0):

host: ppc.fixx.ru
port: 8437
user: UserName.1
pass: Password


Если есть вопросы и предложения, задавайте их тут, или на support@fixx.ru, постараемся решать оперативно.

Внимание новичкам! Система PPNLS, не выплачивает вознаграждение за каждую шару, как в PPS (Pay Per Share). Пока пул молод и на нем мало мощности, раунды длительны и прибыль может появиться через несколько суток. Фактически, в самом начале, это майнинг в режиме Соло. Но по мере появления новых участников, раунды будут короче, а прибыль регулярной и предсказуемой.

Что будет если у меня украли копию валета?
Валет под паролем  , за него  не беспокоюсь, зубы обломает.

Но злоумышленник запускает мой валет на своем компе, в чистом клиенте Биткоина.
Тот скачивает базу, и выходит в сеть.
Злоумышленник теперь видит мой баланс, историю транзакций, но не может вывести средства.
Что при этом происходит у меня? Возможна ли корректная работа моего клиента, не смотря на наличие в сети его близнеца-копии?

Понятно, что эффективность разных способов добычи различается, но так-как основной метод добычи GPU карты 5 и 6 поколения AMD - энергозатраты не малые. Учитывая, что сложность будет только расти, затраты на энергию только увеличиваться.
А насколько эффективна ваша ферма? Чтоб добыть 1 биткоин, сколько вы расходуете электроэнергии в киловаттах?
