AISC grade miner

1. At present, the total network computing power of lightcoin is about 400g. It is impossible for any miner to achieve this calculation power. At present, the calculation power of the world's best lightcoin miner is less than 1G. It is estimated that such a high computational power is sky high

when Leyte coin was born, its founder claimed that Leyte coin was not suitable for AISC. Now, Leyte coin has fallen sharply, which has nothing to do with mining machinery manufacturers

I guess it's bitcoin miner. Miner with 400g computing power is very common. The mainstream Avalon 3 single-mode group 290g on the market, the price is only about 1800. The price of ant s3440g is 2550 yuan.

2. Yes
the advantage of the video card miner is that it can dig other coins after one coin is collapsed. AISC mining machine is more efficient, but it can only dig a single currency.

3. This is a brand new era of blockchain

before the birth of bitcoin, global information transmission was realized through the Internet's TCP / IP (Transmission Control Protocol / Internet Interconnection Protocol) protocol to achieve high-speed and low-cost transmission. However, with the development of interconnection technology (Internet, Internet of things, VR / AR), the ways of interaction between people and objects, people and information are more diversified, More entities are digitized or token, just the sharing and transmission of information can not meet the economic and social development, so when the entity is digitized or token, people pay more and more attention to the value transfer and how to transfer these assets and values point to point

on October 31, 2008, Satoshi Nakamoto published bitcoin's white paper "bitcoin: an e-cash in peer-to-peer network" for the first time, and proposed to realize value transfer through decentralized bitcoin network. In the bitcoin system, all participants in the whole network are the supervisors of the transaction, and both parties can complete the transaction without establishing a trust relationship. Blockchain technology has changed the way we obtain and share information, creating a new distributed, point-to-point ecological society

before the emergence of bitcoin network, we have been unable to transfer and transmit the value of point-to-point through the Internet without the help of third-party trusted institutions. Bitcoin network is the first value transfer protocol (VTP) running on the information superhighway. At present, with the maturity of blockchain technology, the application scenarios of blockchain are not limited to bitcoin and Ethereum. Bitcoinpc tries to combine the above and below blockchain to form the ecological environment of the third blockchain, and further uses VTP protocol to realize point-to-point value transmission

since 2009, with the value of bitcoin being accepted by more and more people and the price rising, bitcoin market has graally become a mecca for global investors. The reason lies in the continuous improvement of investment threshold, continuous compression of investment profit margin and excessive policy intervention compared with other instries, The symbolic significance of blockchain technology and the low value of currency market have become the fundamental reasons for the continuous influx of funds

at present, the blockchain technology in the market is mainly divided into three times:

& #10146; The first era is a point-to-point e-cash system represented by BTC< br />
➢ The second era is the open smart contract complete solution represented by eth< br />
➢ The third era is to solve the problem of eth performance shortage and block congestion, and strive to achieve better commercial value of public chain cluster

it can be inferred that after nearly a decade of crazy speculation in the early stage of the currency market, the next decade will usher in the golden age of value investment. At this time, how to choose an undervalued and high-quality project has become the primary task, just as Bill Gates invested in Coca Cola

what is BPC

BPC, full name bitcoinpc, bit capacity, is a new cryptocurrency based on proof of capacity (hereinafter referred to as POC)

BPC is a digital asset and application platform of blockchain. It provides a new proof of capacity, and provides bitcoinpcasset and bitcoinpcid functions at the bottom of the system, which makes it very convenient for people to carry out asset digitization business, not just to create native tokens on the blockchain

by taking the capacity of hard disk as the basis of consensus, BPC makes its proction more decentralized, makes it more secure and credible, and enables everyone to participate in the proction of cryptocurrency, and generates credit and value through mathematics

BPC's choice of computer hard disk mining is a disruptive innovation. There are CPU, GPU and hard disk as mining equipment in computer. CPU and GPU can not avoid becoming AISC mining machine in the end. At the same time, CPU and GPU will cause a lot of energy waste. The hard disk has the characteristics of anti AISC and power saving. The hard disk can keep its operation only by simple disk scanning. BPC chooses hard disk mining to avoid the defects of CPU and GPU perfectly. The maximum mining capacity of a single mining machine is 8t, avoiding some POC currencies, After a certain stage of development, small households can't enter the market, but big ones are playing. They are playing the same way as POW mining. Small capacity PC mining machine makes it easier to lay out the ecology, enter thousands of households, and realize the idea of Zhongben congren mining. The revolution of POC mining has already started, and the next wave of bull market will proce the leading currency of POC. We'll see< Deterministic: the behavior of the program is deterministic, and the consensus is reached, and the non deterministic factors are excluded in the design of the system

2. Time: Based on POC mechanism, BPC provides system call based on block time stamp, which can regard the whole blockchain as a time stamp server and obtain the time stamp when any block is constructed< Randomness: bitcoinpc runs in two ways to obtain random numbers:

(1) when each block is constructed, the consensus node will reach a consensus on a random number and fill it into the field of the block, and the mining program can read the word segments of any block

(2) the mining program can use the hash value of the block as a means of generating random numbers, Because the hash value of a block is random, a weak random number can be obtained by this method< Data source: bitcoinpc provides two kinds of deterministic data sources:

(1) blockchain ledger

the program can access all the data on the whole blockchain through interoperability services, including complete blocks and transactions, as well as each of their fields. The data on the block is deterministic and consistent, so it can be accessed safely

(2) contract storage space

every node deployed on bitcoinpc has a private storage area which can only be accessed by the node itself. The consensus mechanism of bitcoinpc ensures that the storage state of each node is consistent. Bitcoinpc does not provide a direct way to access the data outside the chain. It needs to send the data outside the chain to the inside of the chain through transaction, so as to convert it into the above two types of data sources before it can be accessed

5. Node call: bitcoinpc nodes have the ability to call each other, but cannot call recursively< High performance: bitcoin PC adopts lightweight VM (virtual machine) as its node's execution environment, which has fast startup speed and small resource occupation, so it is suitable for short programs like nodes. JIT (just in time compiler) technology can significantly improve the execution efficiency of virtual machine

7. Extensibility: the calling relationship between nodes of bitcoinpc is static, and the calling target cannot be specified at runtime

8. Low coupling: bitcoinpc system adopts low coupling design, and the block program communicates with the outside through the interoperability service layer when executing< High efficiency and energy saving: the mining economic model of POC makes miners become a community of ecological interests, and uses money as a new means of proction to replace the original power consumption resources, which makes the whole ecology of BPC expand automatically. Everyone in the world who can buy a hard disk can participate in mining<

BPC application scenarios

superconcting transaction: bitcoinpc will incubate blockchain superconcting transaction projects in the future<

smart Fund: bitcoinpc will increase investment in smart fund projects in the future. It is very similar to the Dao project based on Ethereum, but it tries to improve security through some methods to avoid repeating the mistakes of the Dao

cross chain interoperability: bitcoinpc provides support for the implementation of cross chain interoperability, which can not only realize cross chain asset exchange, but also run cross chain distributed transactions, run on different blockchains, and ensure their consistency<

BPC distribution mechanism

total number of BPCs issued: 42 million

4.2 million (10% of the total number): used to motivate bitcoinpc developers and bitcoinpc board members (pre excavation)

2.1 million (5% of the total number): used to encourage bitcoinpc community construction (output of each mining block)

35.7 million (85% of the total number): used for miners to mine
