Hello.
Correct me if I wrong.
I want to know exactly how share look and work.
As I understood, share this is closest hash that contain specific zero's relative to current pool difficulty.
For example, if I started mined zcash, and next block must contain 10 zeros at the start of hash in order to be a block solution, so every miner can send share(that look like hash with more than 5 zeros at the start) and this will be share?
So share - is a hash that looks like a closest solution to create block? And each miner send this share to pool, and based on this data, pool can calculate miner hasrate?

Now, I’ll tell you about the best graphic cards for Ethereum mining.
The best graphic cards for Ethereum mining are GeForce GTX1080, GeForce GTX1070, and GeForce GTX1070ti, and Radeon Fury X. The most powerful one among them is considered to be Geforce GTX 1070. Its video memory is 8 Gb. The video memory of Radeon RX 470 and Radeon RX 480 is varied in the range between 4 and 8 Gb. The video memory is varied in the range between 3 and 6 Gb. The graphic card Radeon Fury X has the lowest indicator.
Today, the main bestseller in the ratio the price and efficiency is considered to be the graphic card GTX 1060 with the video memory 6 Gb. On Amazon, you can buy it for $259.00. The hash rate of such card is 22, 5 Mh/s. Also one of the advantages of such video card is a low level of electricity consumption – only 90 W. The efficiency of Ethereum mining on such card is 0, 25 Mh/ W. Such card helps you get a profit $39.04 per month without the electricity cost.
One of the most popular graphic card for Ethereum mining is GTX 1070. Its hash rate is 30 Mh/ s, the level of the electricity consumption is 120 W, and the efficiency of Ethereum mining on such card is 0, 25 Mh/ W. If you decided to mine Ethereum, you should choose the model GTX 1070. This card with the video memory 3 Gb costs $ 323, 74, while the price of the card Geforce GTX1080 reaches $721.89. The hash rate of GTX1080 for Ethereum mining is 23, 3 Mh/ s, but it consumes more than GTX 1070 for 20 W, so it’s not a very good option for Ethereum mining, as you guessed. The card GTX1070 will get you a profit $52.05 per month in spite of the electricity cost. So that, your purchase will pay off in average for a half of year in the same manner as buying GTX 1060 disregarding the electricity cost.
If you mine Ethereum on the card GTX1080, you can earn $40.43 per month. It’s meaning that your purchase will pay off for the one year and a half. So that it’s not a very profitable option for Ethereum mining.
Let’s discuss the card for Ethereum mining GTX 1080 Ti. Its hash rate is 35 Mh/ s, the level of the electricity consumption is 140 W, and the efficiency of the mining is 0, 25 Mh/ w. On Amazon, the cheapest one from this layout costs $867,79. This card is too expensive whereas a high level of the hash rate. This card will get you a profit $60.73 per month and will pay off for 1 year and two months in spite of the electricity cost.
GTX 1060 has a very simple cooling system. It consists of one heat pipe matching Ethereum mining. The video memory is 3072 Mb, the core frequency is 3072 Mhz, the memory frequency is 8008 Mhz.
In order to rectify this card for Ethereum mining, it’s better to put fan rpm for 70 percents, Power Limit for 90 percents, the memory for +900, and the GPU for 175. With such settles, the card will provide the temperature 62 degrees.

Do you believe that in ancient times (like a thousand years ago) people had a better living, or were wiser, braver, or had any special knowledge? Suffered less or more? Had better social order? I am looking forward to hearing your opinion and arguments and strongly appreciate links to relevant academic articles and books you can advise.

There are two the best manufacturers producing graphic cards providing miners with a high level of the efficiency. Among them, there are nvidia and amd. You should pay your attention to the hardware produced by nvidia such as GeForce GTX1080, GeForce GTX1070, and GeForce GTX1070ti. Their video memory is 8 GB. And the video memory of GeForce GTX1080ti is 11 GB. The more this indicator is, the higher level of efficiency is.
Today, NVIDIA GTX 1050 Ti isn't a very good option for cryptocurrencies. It offers a low level of the efficiency, so it’s considered to be not very profitable hardware for mining. It’s suitable for mining of cryptocurrencies such as Zcash and Ethereum. Its hash rate for Ethereum is 13, 9 Mh/s and for Zcash 180 h/s. But despite a low level of the hash rate, it’s popular for its low level of energy consumption.
The second place of the top is Nvidia GeForce GTX 1080 Ti. It offers users a high level of the efficiency. This is 35 Mh/s for Ethereum mining, 830 h/s for Monero mining and 685 h/s for Zcash mining.
The third place of the top is Radeon RX 580. Its video memory is 8 GB. The main advantage of this hardware is the price. It costs only $ 279. For those, who want to equip their own home mining farm consisting of 6-8 cards, this is a real catch.
Geforce GTX 1060 is characterized by a low level of the video memory from 3 till 6 GB. It provides hash rate of the graphic card for Ethereum 22, 5 Mh/s, for Zcash 270 h/s, and for Monero 430 h/s. The manufacturer tells us that they are characterized by the stability and longevity. It costs from $ 259 till $ 500. All the miners all over the word tell think this is the best graphic card for mining in 2018, because it will pay off for four months. The best model of the graphic card is RX 470.
A good option for home mining is the layout GeForce GTX 1050 Ti. You can find it easy. It costs from $ 190 till $ 233.
GTX 1070 has high technical characteristics. Its hash rate is really high, because it reaches 30 Mh/s for Ethereum, 630 h/s for Monero, and 430 h/s for Zcash. But because of its high price that is $ 500, it’s not profitable. You must spend 5 months for paying off.
But the most expensive models in the history of NVIDIA’s graphic cards manufacturing are GTX 1080 Ti. It provides the speed more in twice than GTX 1070. GTX 1080 Ti costs from $867.79 on Amazon while GTX 1070 costs only $500.
If you decided to mine coins using hardware produced by amd, it’s more suitable for hashing algorithm Equihash used in Zcash. Also, you can mine CryptoNight used in Monero with it.
You can get the highest profit using graphic cards with Vega GPU architecture. Among them, there are models such as Vega Frontier Edition, RX Vega 64, Radeon RX Vega 56. The graphic cards produced by AMD are more expensive compared to hardware produced by nvidia. The cheapest one costs $ 680 and the most expensive costs $ 800.
Graphic cards such as AMD RX 470 4Gb, AMD R9 390, AMD RX 570 4Gb, and AMD RX 550 4Gb offer their users the least term of the paying off. The term of paying off for such graphic cards in average reaches 7 months.

In brief, this technology uses HLTC, which is the combination of two different technologies, hashlock and timelock. Hashlock contains a cryptographic task (something like a secret password), which guarantees that any part cannot send its funds unless another part has done so. The timelock acts as a protection in case if within a certain time one of the participants canceled the transaction or did not fulfill the contract conditions within a certain period of time.
So, in our situation, the atomic swap acts as the arbitration of the cryptocurrencies exchange transaction. An important condition is a limited time - all participants confirm their participation within certain deadlines. Otherwise, one of the terms of the exchange will be violated and the transaction will be canceled.
Let's say you decided to exchange your BTC for LTC of Anna Smith.
You open a payment channel in the Bitcoin, while Anna Smith opens a similar payment channel in LiteCoin blockchain. After that, you need to create and specify a contract using a swap. The contract contains all the necessary information, the number of coins, wallet addresses, information about payment channels, etc.
You generate data that you sent 1 BTC to the Bitcoin-wallet of Anna Smith. However, this data contains information that as long as the number of Litecoins specified in the contract is not received on the light-coin wallet, your BTC will not be sent to Anna Smith. Similar data are specified by Anna Smith.
Therefore, the arbitrator of the transaction is the blockchain itself, which does not allow the participants of the transaction to deceive each other. If one of the terms of the contract is not fulfilled, the transaction is simply not executed and the coins remain in the owners' hands. This allows you to ignore centralized exchanges and make transactions directly between users, which opens the possibility of creating a decentralized exchange that will not have access to the funds of users - but only to help them find each other.

Do you know that 2017 was a year when the largest number of ICO happened during all the history of ICO? The most popular among them were Mybtgwallet.com, BitCard, Confido, ToTheMoon, Karbon, and others.
Mybtgwallet.com was founded by the member of the community Bitcoin Gold. Users of the website have lost more than $ 3, 3 million. Scammers have got an access to their wallets and diverted money into a different Bitcoin address.
The next scam ICO was BitCard having raised $5 million. Their scam idea was to redesign the structure of the modern business, trading, and government. Anything they were promising wasn’t put into life. After the ICO finish, the team disappeared without the product launch.
One more scam ICO in 2017 was Confido. Scammers raised more than $375,000 million. They announced themselves as a "smart contracts" startup. But after the ICO, the team deleted all their accounts from the social media and website.
Another scam ICO was held by ToTheMoon. They raised more than $27 million. These guys promised “full-service mining solution”, and improving maintenance, hosting, repair, and blockchain servicing. Nothing of these plans was put into life. In fact, they copy pasted word by word another project’s whitepaper including the idea, mission, product implementation, schemes, and graphics.
The last one is named Karbon. This project has to become a decentralized social marketplace but hasn’t. The team proposed a unique ecosystem where users, merchants, and advertisers got an opportunity to communicate with each other in a very convenient way. But nothing of the promises has come true.
This is the list of the most popular scams of 2017. I think 2018 will become a year with not less number of ICO scams, so that let’s be vigilant!

What does “a threshold scheme” mean? It’s an improved version of the escrow service, when an agreement of all the parties, who have secret information, isn’t required. To get an access to the information, it`s necessary only to have an agreement of three of five parties. You can even divide all the parties into several groups: trusted and not trusted. For example, there are three parties whom you trust and three whom you don’t trust hardly. So to get an access to the secret key, you must get the agreement of two people from the trusted group and one from the not trusted or three from the trusted group and two from the not trusted group. If one of the parties lose the key, it’s not necessary to change the key. How do you think this scheme is a convenient way to secure your coins?

As you know, one of the most popular kinds of manipulations on the cryptocurrency market. Big players on the cryptocurrency market are known as whales. They can manipulate the cryptocurrency price using the tactic “Pump and dump”. Whales buy a lot of cryptocurrency in several days causing price increases. This attracts new investors to the cryptocurrency because hamsters want to buy more cryptocurrency in hopes that the price will be raising and they will be able to sell assets for the higher price. But this isn’t happening, because whales, after gaining a specified mark, begin to dump coins. In such way, whales get a profit, and the price of the cryptocurrency falls. How do you think how not to become the prey of such kind of whales` manipulations?

Obviously, all cryptocurrencies and related products are based not only on the trust but also on specific mathematical algorithms and business models. In other words, cryptographic is not a deception, but the decision to ban such advertising by companies such as Google and Facebook actually equates the cryptocurrency to gambling or pornography.
In the end, paradoxically, it is possible that such a ban will actually have positive effects. It encourages all participants to avoid any automated types of advertising. Probably, the trust between the participants will increase due to interpersonal communication and stable partnership relationships within the community. In the long run, perhaps the leaders in the online market will change their decision, but so far it makes sense to use those marketing tools that attract the target audience of your product and provide convenient and trustful communication.
What do you think?

In this article, I am going to explain what is escrow service and why it is useful.
The main disadvantage of the Bitcoin network is the inability to cancel the transaction. Such innovative tool as multisig allows eliminating all problems arising during the transactions confirmation.
If the user of the network decides to purchase the product or pay for the service, but he does not trust the seller, it is best to use escrow services, which keeps the funds until both parties reach a consensus. In this case, each party provides a public key to create a new address. To confirm the transaction, it is necessary that both parties put their electronic signatures.
After making an order, the user must transfer the required sum to the seller's account. But to ensure the maximum safety of money transfers, money from the buyer does not go directly to the seller's account but passes through a special transit account. After notification of receipt of funds, the seller sends the goods ordered by the buyer and generates the transfer of the sent sum from the transit address to his account. The sum of the transfer is frozen for a while until the buyer or escrow puts its electronic signature. If the parties can not come to an agreement, escrow enters into the game. For example, if the goods were not provided or delivered to the wrong address, the buyer generates a transfer of funds from the transit account back to his wallet.
As you can see, escrow is a very convenient tool for protecting transactions by involving a third party, which acts as a guarantor of the return of funds to your wallet, in case you are not satisfied with the goods or service.

As I was a student, I wondered that only state could issue money. What if this state is corrupted? Or stop existing? I realized that it seems like all people only imagined that their money has real value because in fact, it was not so.
Today any person may create a currency and that is rather a challange than a problem. However, it seems like people trust each other more than it was 10 or 20 years ago. And it seems like all the limits are gradually disappearing. We already have smart contracts, the possibility to buy and sells goods using cryptocurrencies, and what is more important - we have a freedom and opportunity to choose what we like or not. Basically, the sum of those choices designs the future. I think that decentralized communities would win and the states in classical meaning would finally collapse.

As for me, masternodes is a much better solution because you do not have to buy that equipment that requires a place, a lot of energy, and endless improvement. Also, it looks like nowadays only very rich people may mine and in fact, they control the bitcoin. That is why I would rather choose some other cryptocurrency where I can become a member that has controlling power (that what happens when you buy masternodes). Another point is pollution and ecology. It is quite sad that in 21 century we still do not care about the environment when it goes about big money. Finally, I do not believe that bitcoin would lead for long. Because whoever controls it (or not), they do not care about future.

We all get used to the idea that sharing with people who have less is good. Particularly, I think so as well and often donate money when I have a possibility. For example, I have once donated to support building a school in a mountain village in Nepal. However, I have never tried to find out if the school was built in reality. I don`t know if it is irresponsible or not. But I have a feeling that many people act in a similar way. In result, charity turns into a kind of apologize. However, this apologize is like empty - because people continue to live their everyday lives and do not care about wars, ecology, or any other global problems, which do not affect them personally. Sometimes, it seems that charity makes people even more careless because it creates an illusion of compassion. Like - I have made a donation, so now I can sleep well.
So, is charity good or not? Or probably we should make an independent decision in each case of donating money, without going deep inside into the idea of charity itself?
