Ⅰ Blockchain Consensus Mechanism

PoW: Proof of Work (PoW for short), the simple explanation is a certificate to confirm that you have done A certain amount of work. Because the entire process of monitoring work is usually extremely inefficient, it is a very efficient way to prove that the corresponding workload has been completed by certifying the results of the work. For example, graduation certificates, driver's licenses, etc. in real life are all certificates obtained through inspection results. This means that how many coins you receive depends on the effective work you contribute to mining. Simply understand, the better your computer performance is, the more benefits you will get. This is to execute the distribution of coins according to your workload. Most digital currencies, such as Bitcoin, Litecoin, etc., are virtual currencies based on the PoW model (the higher the computing power and the longer the mining time, the more coins you get).
PoS: PoS is a consensus algorithm in the public chain and can be used as an alternative to the PoW algorithm. PoW is the mechanism that keeps Bitcoin, currently Ethereum, and many other blockchains secure, but the PoW algorithm has been criticized for damaging the environment and wasting electricity during the mining process. PoS attempts to solve these problems by replacing the concept of mining with a different mechanism.
The PoS mechanism can be described as a kind of virtual mining. PoS mainly relies on the tokens in the blockchain itself. In PoW, a user may buy a computer with $1,000, join the network, mine and generate new blocks, and receive rewards. In PoS, users can purchase tokens of equal value with $1,000, and put these tokens as deposits into the PoS mechanism, so that users have the opportunity to generate new blocks and be rewarded. In PoW, if a user spends $2,000 on hardware equipment, they will of course receive twice the computing power for mining, and thus twice the reward. Likewise, by investing twice as many tokens as a deposit in a PoS mechanism, you have twice as much chance of gaining the right to generate a new block.

Ⅲ What is the IPFS mining machine and how does it make money? Is the income really high?

IPFS is similar to http and is a file transfer protocol. For IPFS to run, it requires many computers (storage devices) as nodes in the network. Broadly speaking, all participating computers can be called IPFS mining machines.

In order to attract more users to join as nodes and contribute to the network, the IPFS network has designed a cryptocurrency called filecoin, which is distributed according to the amount of storage space and bandwidth contributed.Give rewards to participants (nodes). In a narrow sense, a computer designed specifically for obtaining filecoin rewards is called an IPFS mining machine.

Since the IPFS network requires storage space and network bandwidth, in order to obtain the highest revenue ratio, IPFS mining machines usually enhance storage space and reduce the power consumption of the entire machine. For example, equipped with more than 10 large-capacity hard drives, equipped with Gigabit or higher speed network cards, using ultra-low power consumption architecture processors, etc.

Of course, the mining machine provides storage services and can earn profits. The size of the income is related to the configuration of the mining machine and the current number of IPFS mining machines.

(3) What are the further readings on the blockchain token mining mechanism?

The reasons why it is not recommended to invest in IPFS:

1 , IPFS technology is too early and difficult to be commercialized.

IPFS now takes up a lot of bandwidth. IPNS is currently very slow, which is an obvious technical flaw. It will be very difficult to implement dynamic web pages only through IPFS.

2. Lack of a reasonable economic model, even if the token economy is added, it is difficult to achieve long-term natural ecological value.

As an extremely cumbersome decentralized protocol, IPFS is difficult for users to share files autonomously and voluntarily. In addition, even if users share files into the protocol, the files will be completely public. And users cannot effectively delete files, so the security of valid files is threatened.

The solution is to introduce encryption and blockchain incentive mechanisms. At the same time, it solves the problems of file security and storage power. But as mentioned before, nodes with proof-of-work under any blockchain incentive mechanism will face the economic problem of a persistent on-state.

3. It is difficult to establish an ecological network with IPFS as the core due to technical problems.

The ecological application space of IPFS is quite limited, and the project interaction speed achieved through the IPFS protocol is also very slow. Of course, this is directly related to the number of nodes and the distance of the call.

IV Waiting online, the principle of mining with mining machines

Mining with mining machines refers to the process in which users use specific hardware equipment (mining machines) to mine digital currencies. The working principle of a mining machine is: it uses specific software and hardware components to complete the mining process, using the processing power of the computer to solve complex mathematical problems in the digital currency network, thereby obtaining digital currency rewards.

The specific process of miner mining is: first, the miner will obtain new transactions from the blockchain network and combine them into a new block; then, the miner will calculate the new block The hash value, that is, the block header; then, the miner will check whether the hash value of the new block meets the requirements of the blockchain network. If it meets the requirements, the miner can add the new block to the blockchain network; , the miner will receive certain digital currency rewards.

Mining machine miningThe principle of the mine is based on blockchain technology, which is a distributed ledger technology that can record all digital currency transactions and ensure that these transactions are safe and reliable. Blockchain technology is a distributed ledger technology that can record all digital currency transactions and ensure that these transactions are safe and reliable. The core principle of blockchain technology is that a network of mining machines can use computer processing power to complete complex mathematical problems and obtain digital currency rewards.

The advantages of mining with mining machines are: it allows users to obtain digital currency rewards without worrying about security; it allows users to participate in digital currency transactions more conveniently; it allows users to participate in digital currency transactions more quickly; Earn digital currency rewards; it allows users to participate in digital currency transactions more safely.

The disadvantages of mining with mining machines also exist: mining with mining machines requires the purchase of professional hardcore equipment, and the prices of these equipment are relatively high; mining with mining machines requires a large amount of Electricity, and the electricity bill is relatively high; the computing power of mining machines is also limited, and the mining speed is relatively slow; the benefits of mining with mining machines are also limited, because the prices of digital currencies such as Bitcoin are also limited.

In short, mining machine mining is a technology that uses computer processing power to solve complex mathematical problems in the digital currency network to obtain digital currency rewards. It has the advantage of obtaining digital currency rewards. But there are also some disadvantages, such as high hardware purchase costs, large power consumption and limited benefits.

IV How to make money by mining in the blockchain

The principle of making money by mining: PoW and mining.

In the beginning, Bitcoin could be mined using graphics cards, but in 2013, it was no longer possible to mine Bitcoin BTC using general-purpose computing programs for graphics cards. Bitcoins are now all mined using ASIC mining machines. ".

Similarly, the launch of Litecoin ASIC mining machines in 2014 also ended the history of Litecoin mining using graphics cards. The current digital currencies that graphics cards can "mine" are Ethereum ETH, Ethereum Classic ETC, and Zcash Zerocoin ZEC.

Graphics card "mining" is not a profitable business. In fact, the earlier you start, the higher the income will be, and the income will decrease as more miners and graphics cards are added.

To put it bluntly, buying a high-priced graphics card to enter "mining" will definitely kill you. Purchasing a professional mining machine is a more cost-effective choice. Nowadays, the essential tool for personal mining is a mining pool. The function of a mining pool is to gather a large number of mining machine computing power to increase your chances of mining coins. At the same time, the coins you can mine in the future are evenly distributed to your account in advance.

Take Bitcoin as an example. If the entire Bitcoin network now generates a block every 10 minutes, this block contains 25Bitcoin. Assuming that there are 10,000 people in the world participating in mining, then within these 10 minutes, only one lucky person will take away the 25 Bitcoins.

Others have nothing to gain. The principle of the mining pool is that everyone forms a team to mine and allocate according to the agreed distribution method, so that the miners' mining returns tend to be stable and the miners' risks are reduced.

In order to enhance the cost performance, you can also purchase some practical mining machines like Wanke Cloud, which can be used as ordinary hardware products and can also be used for mining, killing two birds with one stone.

(5) What are the further readings of the blockchain token mining mechanism?

There are several core operating cores of blockchain transactions and digital currencies:

The transaction network connected by decentralized databases is called the blockchain. All our clients (including mining machines) keep accounts together, confirm transfer transactions, and issue a certain amount of digital currency according to time.

Because the winner takes all, small and medium-sized retail miners have to unite to form a "mining pool" and record the cumulative workload in Shares. The higher the joint computing power, the greater the probability that the mining pool consortium will find the digital currency first. Large, increase the probability of finding newly issued digital currencies, and divide the mined digital currencies. This is called the PoW workload proof mechanism.

VI Blockchain technology: What are the core blockchain technologies?

What is the hottest Internet topic at the moment? You don’t need to explain it to the editor to know that it is the blockchain. Blockchain technology, but many friends have only heard of this technology and do not have much in-depth understanding of it. So what are the blockchain technologies? Below we will bring you an introduction to the core technology of blockchain for your reference.
What are the core elements of blockchain technology?
Blockchain technology can be a public ledger (visible by anyone) or a permissioned network (visible only by those authorized), which solves supply chain challenges , because it is an immutable record that is shared among network participants and updated in real time.
Blockchain technology----data layer: designing the data structure of the ledger
Core technology 1. Block + chain:
Technically speaking, block is a data structure that records transactions. Reflects the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain.
Each block consists of a block header and a block body. The block body is only responsible for recording all transaction information in the previous period, mainly including the number of transactions and transaction details; the block header encapsulates the current version number, previous A block address, timestamp (recording the time when the block was generated, accurate to seconds), random number (recording the value of decrypting the answer to the math question related to the block), target hash value of the current block, and Merkle number Root value and other information. From a structural point of view, most functions of the blockchain are implemented by the block header.
Core technology 2. Hash function:
The hash function can convert data of any length into a set of fixed-length codes through the Hash algorithm. The principle is based on a cryptographic one-way hash function. This function is easy to verify, but difficult to verify. Crack. Usually, the industry uses y=hash(x) to represent it. This hash function implements operations on x to calculate a hash value y.
Commonly used hash algorithms include MD5, SHA-1, SHA-256, SHA-384 and SHA-512, etc. Taking the SHA256 algorithm as an example, inputting any string of data into SHA256 will result in a 256-bit Hash value (hash value). Its characteristics: the same data input will get the same result. As long as the input data changes slightly (for example, a 1 becomes a 0), a completely different result will be obtained, and the result cannot be predicted in advance. Forward calculation (calculating the corresponding Hash value from the data) is very easy. Reverse calculation (cracking) is extremely difficult and is considered impossible under current technological conditions.
Core technology 3. Merkle tree:
Merkle tree is a hash binary tree, which can be used to quickly verify the integrity of large-scale data. In the blockchain network, the Merkle tree is used to summarize all transaction information in a block, and ultimately generates a unified hash value of all transaction information in the block. Any change in transaction information in the block will cause Merkle tree changes.
Core technology 4. Asymmetric encryption algorithm:
Asymmetric encryption algorithm is a key secret method that requires two keys: public key and private key. The public key and the private key are a pair. If the public key is used to encrypt the data, only the corresponding private key can be used to decrypt it, thereby obtaining the corresponding data value; if the private key is used to sign the data, then only the corresponding public key can be used to sign the data. In order to verify the signature, the sender of the verification information is the holder of the private key.
Because encryption and decryption use two different keys, this algorithm is called an asymmetric encryption algorithm, while symmetric encryption uses the same key in the encryption and decryption processes.
Blockchain technology----network layer: realize the decentralization of accounting nodes
Core technology 5. P2P network:
P2P network (peer-to-peer network), also known as point-to-point technology, is no Central server, Internet system that relies on user groups to exchange information. Unlike a centralized network system with a central server, each client in a peer-to-peer network acts as both a node and a server. Domestic Xunlei software uses P2P technology. The P2P network has the characteristics of decentralization and robustness.
Blockchain technology----Consensus layer: allocate the task load of accounting nodes
Core technology 6. Consensus mechanism:
Consensus mechanism is how to reach consensus among all accounting nodes to identify The validity of a record is both a means of identification and a means of preventing tampering. There are currently four main types of consensus mechanisms: PoW, PoS, DPoS and distributed consensus algorithms.
PoW (Proof of Work, proof of work): PoW mechanism, which is like Bitcoin’s mining mechanism, miners package existing transactions that have not been recorded by the network into a block, and then continue to traverse and try to find a random number , so that the hash value of the new block plus the random number meets certain difficulty conditions. Finding a random number that meets the conditions is equivalent to determining the latest block of the blockchain, and is also equivalent to obtaining the current round of accounting rights of the blockchain. Miners broadcast blocks that meet the mining difficulty conditions in the Yuanfu network. After verifying that the block meets the mining difficulty conditions and that the transaction data in the block meets the protocol specifications, other nodes in the entire network will each Blocks are linked to their own version of the blockchain, thereby forming a network-wide consensus on the current network state.
PoS (ProofofStake, Proof of Stake): PoS mechanism requires nodes to provide proof of a certain number of tokens to obtain a distributed consensus mechanism for competing for blockchain accounting rights. If you rely solely on the token balance to determine the bookkeeper, you will inevitably make the rich win, which will lead to the centralization of bookkeeping rights and reduce the fairness of the consensus. Therefore, different PoS mechanisms use different methods to increase the amount of money based on the proof of equity. The randomness of accounting rights avoids centralization. For example, in the PeerCoin PoS mechanism, the Bitcoin with the longest chain age has a greater chance of obtaining accounting rights. NXT and Blackcoin use a formula to predict the next accounting node. The more tokens you own, the greater the probability of being selected as an accounting node. In the future, Ethereum will also switch from the current PoW mechanism to a PoS mechanism. Judging from the information currently available, Ethereum's PoS mechanism will use nodes to place bets on the next block. The winner of the bet will receive an additional Ethereum currency award. Those who do not win will be deducted Ether coins to reach consensus on the next block.
DPoS (DelegatedProof-Of-Stake, share authorization certificate): DPoS is easy to understand and is similar to the modern corporate board of directors system. The DPoS mechanism adopted by BitShares is that shareholders vote to select a certain number of witnesses. Each witness has two seconds of authority to generate blocks in order. If the witness cannot generate a block within the given time slice, The block generation authority is given to the witness corresponding to the next time slice. Shareholders can replace these witnesses at any time by voting. This design of DPoS makes the generation of blocks faster and more energy-saving.
Distributed Consistency Algorithm: Distributed Consistency Algorithm is based on traditional distributed consistency technology. Among them are Byzantine fault-tolerant algorithms that solve the Byzantine Generals problem, such as PBFT (Byzantine fault-tolerant algorithm). In addition, distributed consensus algorithms (Pasox, Raft) that solve non-Byzantine problems are not explained in this article. This type of algorithm is currently a commonly used consensus mechanism in alliance chain and private chain scenarios.
Taken together, POW is suitable for use in public chains. If you build a private chain, since there is no trust issue with verification nodes, POW can be usedOS is more suitable; and due to the existence of untrustworthy local nodes in the alliance chain, DPOS is more suitable.
Blockchain technology----Incentive layer: Develop a "salary system" for accounting nodes
Core technology 7. Issuance mechanism and incentive mechanism:
Take Bitcoin as an example. Bitcoins are initially rewarded by the system to miners who create new blocks, and this reward is halved approximately every four years. At the beginning, miners were rewarded with 50 Bitcoins for each new block recorded, and this reward is halved approximately every four years. By analogy, by around AD 2140, newly created blocks will no longer receive rewards from the system. By then, the total number of Bitcoins will be approximately 21 million. This is the total number of Bitcoins, so it will not increase indefinitely.
Another source of incentives is transaction fees. When there are no system rewards for newly created blocks, the miners' income will change from system rewards to transaction fees. For example, when you transfer, you can specify 1% of it as a handling fee to be paid to the miner who records the block. If the output value of a transaction is less than the input value, the difference is the transaction fee, which will be added to the incentive for that block. As long as a given amount of electronic currency has entered circulation, the incentive mechanism can gradually be converted to rely entirely on transaction fees, so there is no need to issue new currency.
Blockchain technology----Contract layer: giving the ledger programmable features
Core technology 8. Smart contract:
Smart contract is a set of programmed rules and logic that respond to scenarios. Implemented by decentralized, trusted shared script code deployed on the blockchain. Normally, after the smart contract is signed by all parties, it is attached to the blockchain data in the form of program code, and is recorded in a specific block of the blockchain after being propagated through the P2P network and verified by nodes. Smart contracts encapsulate a number of predefined states and transition rules, scenarios that trigger contract execution, response actions under specific scenarios, etc. The blockchain can monitor the status of smart contracts in real time, and activate and execute the contract by checking external data sources and confirming that specific trigger conditions are met.
The above is what blockchain technologies the editor has brought to you? All content of the introduction to the core technology of blockchain.

Ⅶ Is blockchain mining still profitable? Which mining machine is better?

Whether you can make money mainly depends on your electricity cost, such as Bitcoin mining, which mines are now The price of electricity in China is between 2 cents and 4 cents. If you can get such a price, you can do it. Nowadays, most people who mine Bitcoin use Antminers and Shenma Miners.
It’s not easy to code, I hope you will adopt it, thank you!

Ⅷ What conditions are required for mining in blockchain technology

Miners need to configure mining machines. There are two ways to configure mining machines:
The first method It is a cutting-edge mining machine equipped to gain performance advantages in guessing games. The advantages of new mining machines are high computing power, low power consumption, high gross profit, and low shutdown price; the disadvantage of new mining machines is high fixed costs and the need to fill in the pits of this cycle first. Novice mining machines are suitable for new mining machines. The second way is to match it at a low priceBuy second-hand old-model mining machines. The advantage of old-model mining machines is that they are low-priced and can easily return to the original line. The disadvantages of old-model mining machines are that their performance is relatively poor and their life cycles are short. Veteran mining machines often use old-model mining machines. .

Ⅸ Blockchain Technology

Blockchain technology is called distributed ledger technology. It is an Internet database technology. It is characterized by decentralization, openness and transparency, allowing everyone to Individuals can participate in database recording.

Blockchain technology will be applied to credit reporting, transaction security and information security in the financial industry. Financial data security, information privacy and network security are suitable for distributed block technology. Blockchain can form point-to-point digital value transfer in finance, thus improving the security of transmission and transactions.

Domestic blockchain technology companies started late, but there are many ICO projects and they are developing very rapidly. Currently, the well-known blockchain technology companies include Yingtang Zhongchuang, Feifang Sentian Integrity, and Luyi Tong et al.

In these well-known companies, token prices vary, but those that use blockchain technology for commercial applications, such as Yingtang Zhongchuang in Shenzhen, develop commercial application technology and use blockchain The chain commodity Internet of Things comprehensive service platform is the core, providing enterprises and consumers with more competitive production management, warehousing management, anti-counterfeiting traceability, precision marketing and other services.

With the increase of ICO projects, supervision will inevitably follow the trend. Therefore, whether it is well-known or unknown, only by truly applying technology and applying blockchain technology to commercial applications can we truly succeed. More long-term.
