blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chipuses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fastthe reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank youhis Chinese name is bitcoin, which is only one word different from bitcoin. Many cheated people think that they bought bitcoin, and then they understand that they didn't buy bitcoin. Its sinister intentions can be imagined
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

project introction
hcash is a new kind of decentralized, open source The cross system digital cryptocurrency has al side chains and is compatible with blockchain and DAG distributed systems. Hshare (HSR) is a token issued by hcash, which is developed based on the stable blockchain system of utxo model
it will become the connection point of all blockchain systems, allowing the free exchange of value and information between different blockchain systems. This kind of free flow of information and value between decentralized distributed ledgers is defined as "super cash", and hcash acts as the carrier of value flow between different systems. The biggest charm of hcash is to define the beauty of the circulation of digital assets, which greatly releases the value of digital assets in each block. This technology will once again bring the blockchain world back to its original nature, and also bring the new currency world and trust world closer to reality
team members
the super cash team all have rich experience in the blockchain instry, and the CEO is an expert in financial investment. He has been exploring the practical application of digital cryptocurrency. In addition, he is also the host of Australia's well-known financial TV programs. Khal has a bachelor's degree in Computer Engineering and a master's degree in management. He is a successful entrepreneur with 19 years of experience in many fields. He has successfully promoted several complex projects with millions of dollars and achieved excellent results.

If you get a basket of food or a bowl of soup, you will live, if you don't get it, you will starve to death
this sentence comes from "fish I want" and from "Mencius · Gaozi", written by Mencius
The original text is as follows:fish is what I want; Bear's paw is what I want. We can't have both of them. Life is what I want; Righteousness is what I want. They can not be both, and those who give up their lives to take righteousness are also. Life is what I want. I want more than the living, so I don't want to get it; Death is also what I hate, and what I hate is more than that of the dead
if you want nothing more than life, why don't you use it if you can get life? So that people do not hate more than the dead, why not avoid the patients? If it is, it will be born without use, and if it is, it will be able to avoid danger without action. Therefore, the desire is more than the living, and the evil is more than the dead. Not only the sage has a heart, but also everyone has it. The sage should not lose his ear
if you eat a bushel and a bean soup, you will live if you get it and die if you get it. The people who walk the way will not accept it; But with it, beggars disdain it. Wanzhong does not argue for propriety and righteousness, but accepts it. How can Wanzhong add to me! For the beauty of the palace and the honor of the wives and concubines, who know the poor, can I share with you
it is the beauty of the palace to die and not suffer in the countryside; Xiang died for his own body but did not accept it. Now he is honored by his wife and concubine; Is it right or wrong for the poor to die for their own sake? This is called losing one's original intention
Fish is what I want, and bear paw is what I want. If these two things can't be obtained at the same time, I would rather give up fish and choose bear paw. Life is what I want, justice is also what I want, if these two things can not be obtained at the same time, then I would rather sacrifice my life and choose righteousness. Life is what I want, but what I want is better than life, so I don't do anything to muddle alongdeath is what I hate, but there are more things that I hate than death, so I don't avoid some disasters. If there is nothing more important than life that people want, then what means are not available for all the methods that can save life? If people don't dislike more than death, which of the bad things that can be used to avoid disaster can't be done
However, some people refuse to use it; Some methods can avoid disaster, but some people refuse to use them. It can be seen that what they love is more precious than life (that is, righteousness); What they dislike is something more serious than death (that is, injustice). It's not only the sages who have this idea, but everyone has it. It's just that the sages can not lose ita bowl of rice, a bowl of soup, eat can live, do not eat will starve to death. But when they scold others for food, the hungry people who pass by refuse to accept it; Kicking others to eat, beggars are not willing to accept However, some people accept the generous salary without distinguishing whether it is in line with propriety. In this way, what's good for me with a good salary? Is it for the magnificence of the house, the service of the wives and concubines, and the familiar poor people who appreciate me
in the past (some people) would rather die than accept (other people's charity) for (morality), but now (some people) accept it for the beauty of the house; Once upon a time (some people) would rather die than accept (other people's charity) for the sake of (morality), but now (some people) accept it for the sake of being served by their wives and concubines
in the past (some people) would rather die than accept (charity) for (morality), but now (some people) accept it in order to make the poor people they know appreciate their kindness. Can't this stop? This is called the loss of human nature
{rrrrrrr}
extended materials:
Literature Appreciation:
fish I want is selected from Mencius · Gaozi, which discusses an important proposition of Mencius: righteousness is more important than life, when righteousness and life cannot be both perfect, we should sacrifice life for righteousness. Mencius said, "the heart of shame and evil is righteousness." Mencius said: "righteousness is the way." Only a gentleman can make his way
Mencius first made an analogy with the specific things that people are familiar with in life: fish is what I want, and bear's paw is also what I want. If I can't get both at the same time, I would rather give up fish and have bear's paw; Life is what I cherish, and righteousness is also what I cherish. In the case that I can't get both at the same time, I would rather give up life for righteousness
Shan Yu summoned Su Wu's subordinates. Except for those who had surrendered and died before, there were nine people who came back with Su Wu. Su Wu returned to Chang'an in the spring of the sixth year of emperor Zhao of Han Dynasty (81 BC). Emperor Zhao ordered Su Wu to take a sacrifice to visit Emperor Wu's Mausoleum and ancestral temple. Su Wu was appointed as a vassal state of Dian, and his salary was 2000 yuan
Two million yuan, two hectares of government land and one residence. Chang Hui, Xu Sheng, and Zhao Zhonggen were all appointed as the emperor's bodyguards and gave each 200 pieces of silk. The other six, when they were old, went home and gave each of them 100000 yuan to be exempted from corvee for life. Chang Hui later became a right general and became a marquis. He also had a biography. Su Wu was detained in Xiongnu for 19 years. When he was a prime minister, his beard and hair turned white when he came back25919;-31574;- 313508;- http://newcongress.yam.org.tw/
