What is Bitcoin

What is Bitcoin?

Bitcoin is the mainstream cryptocurrency around the world, which can be generated by large number of calculations. People call this process mining. Once the miner (mining machine) calculate the qualifying result, it would get Bitcoin as a reward.

What is Bitcoin wallet?

Bitcoin wallet is the software managing bitcoin address, in which user could receive, send and store the Bitcoin.

What is Bitcoin address?

Bitcoin address (for example: 18AN9XojYq5EU5x8p6pgdYk3RKo6zu9xzy) consists of a string of characters and numbers. Just like others send the email to you, he can send Bitcoin to you via your Bitcoin address.

How to get a Bitcoin wallet?

Users can download Mulitbit wallet on its official website(multibit.org).

What is Bitcoin private key?

It’s the string of characters and numbers that unlock the corresponding Bitcoin address, such as 5J76sF8L5jTtzE96r66Sf8cka9y44wdpJjMwCxR3tzLh3ibVPxh.

How to keep Bitcoin address safely?

Use the backup feature of Bitcoin wallet or keep your private key printed in a safe place.

What is Bitcoin transaction? How to make the transaction?

General speaking, Bitcoin transaction is the process sending Bitcoin from one address to another. Open your wallet, fill in the target address(some wallet supports scaning QR code), send the Bitcoin and the transaction will be done.

Why does Bitcoin transaction take time to wait for confirmations?

When a transaction is included in a block, it could be said there is one confirmation. After this block, with each new one is generated, the number of confirmation will plus one. Once the number reaches 6 and more, the transaction is generally considered safe and irreversible.

What’s blockchain?

Blockchain likes an open ledger, which records all transactions since the birth of Bitcoin. Anyone can download and check this blockchain. A block corresponds to a page on this ledger.

What is mining a block?

According to Bitcoin protocol, every block is generated every 10 minutes roughly. During these time, workers, who complete the computing tasks will get about 12.5 Bitcoin as a reward. This process is called mining a block.

Who does Bitcoin transaction fee pay to?

Bitcoin traders need to pay a transaction fee to the workers mining the block. Workers package the transaction, which is equivalent to recording it in the ledger.

Why is the fluctuation of Bitcoin price so significant?

Similar to the traditional gold, silver and other precious metals, the price is influenced by many factors, such as the political situation, market acceptance and so on. But currently the price is usually higher than bitcoin mining costs, so that the mining process is still profitable.

What’s the condition to mine Bitcoin?

Large-scale mining needs special field with good ventilation, moderate temperature and humidity , stable and affordable electricity, administrators understanding Bitcoin, as well as technical man proficient in maintenance of power line and network.

How to purchase bitcoin miners

FAQ

What's Namecoin? How to receive it when BTC pool gives away namecoin every day?

Namecoin is an altcoin, which improves decentralization, security, censorship resistance, privacy, and speed of certain components of the Internet infrastructure such as DNS and identities.
Users can sign up on BTC-e and Poloniex exchange and get the namecoin address.

What's the difference between the subsidy address and the default address?

The default addresss is to reveive the mining eanrings every day. And BTC pool will give away bitcoin subsidy when we have preferential policy, and users should fill in subsidy address to reveive it. If subsidy address is not filled in, the subsidy will be sent to the default address.

Why don’t I receive the activation email?

Maybe the email is blocked into the trash, or maybe it’s shielded by some related keywords, which requires you to confirm your mailbox settings.

How to mine on BTC Pool/ How to connect the miners to BTC Pool/ How to add the sub-account?

Login the background system of miners, fill in the miner name (the password could be blank) and save the profile. The miners will be added to BTC Pool in a few seconds.Miner name settings: sub-account.001, sub-account.002, etc; each name corresponds to a miner.
Miner ID settings: sub-account.001, sub-account.002, etc; each miner ID corresponds to a miner.

How to login the background system of miners?

Type the IP address of miners into the address bar with a web browser under the local area network. The default account is: username ‘root’, password ‘root’.

How to fill in the password of miners?

The password is recommended to be blank because only a few mining pools now require users to fill in the password.

How to fill in the payment address on BTC Pool?

Login the BTC Pool website, click ‘Settings’ to enter the settings page, then click ‘Edit’ button of the corresponding sub-account and fill in the payment address.

What’s lucky figure?

There is a certain probability to mine a block, sometimes faster sometimes slower. The lucky figure fluctuate around the theoretical value (100%). When the lucky figure is higher, earnings will be higher too, which only affects those selecting PPLNS.

Why will the earnings get less every two weeks?

As the network difficulty ascends every two weeks, it’s normal to get less earnings slightly under the same hash rate.

What’s API?

API stands for ‘Application Programming Interface’, which can be used for technical man to access the status of BTC Pool and miners.

What are the rejected shares?

he rejected shares are the number of shares rejected by BTC Pool because those shares don't meet the requirement of servers. The rejection rate is the proportion of the rejected shares number accounted for the total submitted number. The smaller the rate, the higher the efficiency.

Why is total earnings not equal to the account balance?

Because the PPS mode needs to charge 1.5% fee.

How to configure the difficulty of miners?

If your miners are extremely high or low, configuring a suitable difficulty will improve the efficiency.
Difficulty parameters: d=4096 or d=4096,md=1024, Type these parameters into your password bar in the miner background system.
d=4096 means that the initial difficulty will be 4096 after its connection. md=1024 means that the miner's minimum difficulty is 1024. No matter how low the hashrate is, the pool will never assign a difficulty less than 1024.
In command line, it's:
  • cgminer -o stratum+tcp://cn.ss.btc.com:3333 -u USER_NAME -p d=4096 ...
  • cgminer -o stratum+tcp://cn.ss.btc.com:3333 -u USER_NAME -p d=4096,md=1024 ...
Recommended difficulty is calculated as: D=H*2.3, H is the hashrate, G is unit.
E.g:
  • S9 is 14T, then D = 14000 * 2.3 = 32200, set to d=32200
  • S7 is 5T, then D = 5000 * 2.3 = 11500, set to d=11500
  • U3 is 50G, then D = 50 * 2.3 = 115, set to d=115

Why does the hash rate of miners fluctuate?

It’s normal. The calculating process of miners is not a stable output and it’s expected to get the average hash rate and earnings. Besides, the status of miners, working environment and unstable of network and other factors would affect the hash rate, too. To keep stable earnings, the administrators working in a mining field have to chenk out all the related factors.

What is PPS ?

There is a certain probability factor to mine and sometimes earnings will be lower than the average. Under the PPS mode, you can get 100% of the expected earnings with the subsidies provided by BTC pool. That is, when your miner is connected to BTC pool, your earnings will be directly based on the contribution regardless of luck figure.

About mining fee and Tx fee

When users mine on BTC pool, they should pay mining fee to BTC pool. When users send a transaction to others via bitcoin, they should pay transaction fee to workers.

About BTC.com
BTC.com is the world's leading provider of Bitcoin data, pool and wallet.

In 2015, BTC.com team developed block explorer, and is commit to set new standards for wallet, pool, price, and news under BTC.com brand in the future.

BTC.com team members are from the domestic famous Internet companies. In recent years, members have been dedicated to Bitcoin industry, with experience in system design, development and operation. Team leader, Kevin Pan worked in Baidu and Dangdang and access to Bitcoin in 2011. In 2013, he joined Bitcoin industry, designed miners, and run Tang pool. Now Kevin is working in Bitmain and built BTC.com team.

The team and brand of BTC.com is growing, and we will bring users much better experience.
Technical Features
After several months of development and testing, BTC pool (pool.btc.com) officially launched. In order to further reduce the threshold of the Bitcoin mining industry and to promote the decentralization, BTC Pool is committed to creating new technical standards for the mining pool industry and working with other pools to improve the performance, safety and service.

Open source code

BTC pool code is open source and anyone can access Github to view the back-end code. BTC pool has been through the simulated stress test, which can withstand 180,000 miners connected at the same time. Take the 4.73T Antminer S7 and 14T S9 for calculation, the equivalent of 180,000 S7 equals more than 50% of total network hash rate, and the equivalent of 180,000 S9 equals more than the current full-network hashrate. Now the simulator is available on GitHub.

Multi-node deployment

Given the global network interoperability problems and Chinese special circumstances, BTC pool server deployed in the world's major Bitcoin "producing areas". Miners can choose the nearest regional node to ensure the stability of network connectivity. User's sub-account is tied to a node, which reduces the complexity of BTC pool data and improve the efficiency and stability.

High-speed broadcast network

To reduce the orphaned block rate, BTC pool deployed nearly 20 FIBER node (high-speed broadcast network). With the help of FIBER, BTC pool can monitor other pools and reduce block delay. In order to reduce the overall industry orphaned block rate, the FIBRE Docker developed by BTC pool is available on GitHub.

Transparent agent

In addition to the simulator, the current release includes the transparent BTCAgent, a stratum agent for large-scale mining farm. BTCAgent optimizes the stratum protocol, greatly simplifies the data volume. It will greatly improve the communication efficiency between the farm and the pool, saving bandwidth, stabilizing connection and monitoring data. BTC.com team has been dedicated to mining industry for a long time, well aware that the large-scale network environment is poor, so put BTCAgent as a service standard. According to actual estimates, after deploying BTCAgent, running 10,000 miners only needs 1Mbps bandwidth which is only 10% of the consumption of direct traffic. The download only takes 1/2000 of direct traffic. Also, with the general mining agent, users can't monitor single miner data. But with BTCAgent, users can manage the grouping and moving for all miners.

Security

BTC pool considers that security is a top priority, so BTC pool separates the data reading and writing. BTC pool also implements Cloudfare, protecting users from Ddos and ensuring that benefits and hash power will not be lost.
Service
As an emerging industry, the mainstream pools generally have 2-3 years of operating history, whose service is still in its infancy. BTC.com team knows that this situation should be improved, and is making the following improvements:
BTC Pool is the first to make data real-time.Users will not spend time waiting for data refreshment after connecting miners to the pool.
BTC pool is the first to make App and Web available once it's launched. With BTC Pool App, users can sign up, sign in, create sub-account, manage miners directly. And this app will support event alert function soon.
BTC pool’s customer service is available.Team members can answer user's questions in a professional way. Join telegram(https://telegram.me/btccom) and contact us.
BTC pool team is international.The ticket system can service for English users. After Blocktrail team acquired by BTC.com, members can handle user's tickets from China and abroad timely.
BTC pool VIP server is available.,Users with large hash rate can apply for exclusive server and private IP, which protect them from Ddos attack.
Under the brand of BTC.com, members develop many ancillary products, including BTC block explorer and BTC wallet. And some features like block data counting, mining calculator, recommended fees are welcome by users.
For developers, BTC pool API is almost ready. It will be released soon and developers can access the data later.
