For example, genesis-hash is the (in pseudo-code): sha256(sha256(version+previousblockheader+hash+merkleroothash+time+nBits+nonce)) than convert hash from little endian to big endian - voila! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) It's very easy to understand. Thank you - you explained. And how about Merkle root hash? SHA256(coinbaseTransaction) voila! It's very easy to understand. No. To calculate a root merkle hash, you would use the double SHA256 here: SHA256(SHA256(coinbaseTransaction)) Take a look at the block #1 of Bitcoin: https://blockchain.info/block/00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048This is its coinbase transaction in HEX format: https://blockchain.info/tx/0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098?format=hexIf you will calculate SHA256 against this HEX string, you will get the intermediate hash: 1e120c45180578688c4aa403b2e1e30320baede01c402078cce5d42ca1446ca6 Then you need to calculate SHA256 against this intermediate hash. You will get the merkle root hash in the big endian format: 982051fd1e4ba744bbbe680e1fee14677ba1a3c3540bf7b1cdb606e857233e0e This is a merkle root hash in the little endian format: 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098

как думаете упадет ли биток еще ниже и каковы ваши прогнозы? все-таки падение в 25% многовато
То ли ещё будет... Сейчас Bitcoin ~8100 (-12%), и почти все криптовалюты продолжают рушиться. Здесь, похоже, вмешивается не только экономика некоторых стран, но и ожидаемая мировая геополитика. Полагаю, Bitcoin может упасть до $5000. На этих уровнях, наверно, будет достаточно покупателей.

Google updates financial services After beginning the day on the back foot the losses for bitcoin intensified after Google GOOG, +0.04% announced it was updating its financial-services policy, saying ads will no longer be allowed to service “cryptocurrencies and related content.” Google said the related content includes those for initial coin offerings, or ICOs, cryptocurrency exchanges and wallets. While the news isn’t ideal for crypto investors. https://www.marketwatch.com/story/bitcoin-tumbles-further-as-google-clamps-down-on-crypto-advertising-2018-03-14I think Google isn't guilty in the current panic sale -15%. The reasons of this global fall are not obvious yet, but the rich investors and venture funds know a lot, and they are going out from the crypto exchange markets in the high priority. I guess that we are expecting bad news concerned to the world geopolitics in the near future.

In case of Hard Cap reached, the tokens distribution will be as following: 550,000,000 AMNs tokens will be circulating when Tokens are released after the end of the token sale (30% ICO contributors and 3% bounty programs). Being a FinTech Amon needs a consistent amount of reserve, therefore 450,000,000 AMNs will be allocated for Reserves and will be locked and used only in special events related to the business operations. The 250,000,000 AMNs tokens for Advisors and Team will be vested respectively for 6 months and 1 year while the remaining 416,666,667 AMNs for Founders will be vested for 3 years with a 6 months release programme starting from the 2nd year. Unsold tokens will be burned and the percentages of tokens distributions will remain the same
It's fair that unsold tokens will be burnt. Do you intend to prolong the ICO if the hard cap won't be reached in time? What about KYC procedure for bounty participants?

Hello community! What do you think about popularity of the bounty campaigns? I see many new participants joining bounty campaigns, especially Twitter and Facebook. With more and more new participants, we will earn less and less rewards, also many of potential buyers would rather join bounty campaign than invest to ICO - again less rewards for bounty participants. I hope that we will see some regulations here and bounty campaigns be more strict in rules and they will choose only the best participants. So, what is your opinion, guys?
In present time the merit system was deployed on the BitcoinTalk forum, so the signature campaigns won't be overfilled by high rank users anyway. Yes, many people join the social network campaigns, but some bounty managers limit the maximal count of participants of Facebook or Twitter campaigns. Now the new field for bounty hunters is created - Telegram, but its channels also might be overfilled too fast.

Now the panic sales are occuring on the crypto exchange markets, therefore it's a good chance to buy some promising coins when their prices are not so high.
I advice to fill the investment portfolio by these crypto currencies: Bitcoin (25%) Ethereum (20%) NEO (10%) Cardano (10%) Monero (10%) Bitcoin Cash (5%) and miscellaneous coins (20%)

I think the current global fall is not just a panic sale. The rich investors and venture funds are going out from the crypto exchange markets in the high priority. Why do they sell their crypto currencies now? Because they know a lot. I am expecting bad news which are concerned to the world geopolitics in the near future.

Look at the automatic arbitrage platforms and applications for trading on two or even more crypto exchange markets simultaneously. These platforms work through APIs and analyze certain coin pairs, so you can see the opportunities to yield arbitrage profits in the real time almost with no risk.

Its true bitcoin price is getting lower again. Even if we told everybody to be calm we cant stop that feeling. It is ok to be worry but all we have to do is hold and not do panic selling.
Not only the price of Bitcoin. Almost all crypto currencies are crashing right now -15%. It seems that we are expecting some significant news about the traditional stock markets. Probably, it will be concerned mostly to the world geopolitics. Don't be calm.

Вижу, обновились коды для подписной кампании BitcoinTalk. Почему теперь в подписи не упоминается о проведении PRE-ICO? Может, всех участников подписной кампании (включая Junior Member) обязать сменить их Personal Text на "[PRE-ICO] TOKEN SALE 22 Feb 2018"? Не лучше ли в подписи вместо слова SITE использовать слово PLATFORM?

Если говорить о дереве Меркля, то обычно в генезис-блоке только одна транзакция (coinbase). От этой транзакции нужно просто посчитать двойной SHA256, это будет корневой hashMerkleRoot. Затем нужно собрать заголовок блока, структура которого заранее известна и составляет 80 байт. Потом нужно некоторое время майнить на минимальной сложности и найти требуемое значение nonce. Говоря утрированно, генезис-блок готов.

Has anyone here experienced this market? Is this really profitable as the youtube videos show?
The advantage of some binary options is that no need to deposit your coins on the account of the crypto exchange market for financial derivatives trading. This technology can be used with sport betting.

i really don't understand how the price increase or decrease?i saw that price coin changes randomly.If anyone help to know trading,I will be very grateful.
The price of Bitcoin depends on the balance of a demand and a offer on the crypto exchange markets. To predict the price of Bitcoin you need to know the intends of rich investors who want to buy or sell a huge amount of coins. Also I heard that now crypto currencies confiscated by the law enforcement officers are constantly being sold on the crypto exchange markets. It is bringing negative impact to the price of coins.

Previous few month we see all altcoin price is decrease.So at this time how I recover my loss.I decided one think,I want to sell my all altcoin now.And try to start trade and recovery again.It's possible? Can I do this.Tell me your opinion, can do or not?
Of course, you can do it. I think the current correction won't be eternal, and crypto currencies will grow again in the future. For example, a day ago I heard good news from the South Korea. The government of this country wants to allow some token sales and ICOs which are met the certain conditions. Obviously, it is a positive factor for crypto exchange markets.

CoinDesk reported in September that the country's Financial Services Commission had moved to prohibit the blockchain funding model. Yet a new report from the Korea Times suggests that the ban may be lifted in part, specifically for token sales that meet as-yet-to-be specified conditions.
The audit of token sales is a right direction. I think that some of the promising and honour ICOs should be whitelisted in the South Korea. I wonder what are the "as-yet-to-be specified conditions" in fact.

im sure there are big country trying to destroy bitcoin my be usa or china what can we do to make bitcoin real eco system
Some investors play the game. They want to shake the crypto exchange markets in order to the holders bought Bitcoin on the high levels (about $13K) will sell those coins now. They are not connected to the certain country. They just want to buy or re-buy Bitcoin on the low levels (about $5-6K).

Pre-ICO будет проходить на нашей платформе и на краудфандинговой платформе. Период проведения: с 22 февраля по 8 марта 2018 года. Soft cap: 2 500 000$. Курс продажи Mallcoin 1 ETH = 3000 MLC. Hard cap: 5 000 000$
Я в этой баунти буквально недавно. Смотрю на официальном сайте, капитализация проекта застряла примерно на 1.3 млн долларов. Учитывая общее текущее падение криптовалютных рынков, похоже, даже soft cap не будет собран в ближайшее время. Как долго будет продлеваться PRE-ICO? Может, нужно изменить маркетинговую политику, или обновить дизайны подписей, или упростить потенциальным инвесторам процедуру покупки токенов?

"Google решил запретить всю рекламу связанную с ICO и криптовалютой в своей поисковой системе, два источника знакомые с этим вопросом, рассказали порталу Cryptonews.com.
В любом случае, очередной запрет - это плохая новость для криптовалютных рынков. Честным и перспективным проектам без дополнительных рекламных площадок будет сложнее собрать soft cap и hard cap. С другой стороны, это может негативно повлиять на финансовые показатели самой компании, хотя, разумеется, незначительно.

Он мог ордера поставить, а биржи их тупо проигнорили и цена проскользнула.
Такое навряд ли возможно. На биржах один алгоритм для всех ордеров. Даже если один клиент захочет купить по оверпрайсу, биржа продаст ему ордер по рыночной цене, а разницу заберёт себе. Не может цена "проскользнуть" мимо ордера ниже прайса. Насчёт "потерял на холде" - это ещё не точно. Цены на эти токены могут вернуться к высоким уровням.

Говорят, в некоторые баунти-кампании по социальным сетям набивается по несколько тысяч участников, причём в процентном отношении на соцсети админы выделяют относительно мало токенов. Рекомендации, конечно, разумные, особенно касательно процедуры KYC.
