『二』Do you know what features IPFS has compared to HTTP?

IPFS has features:

① Fast download speed, no longer Rely on a backbone network or centralized server. The entire IPFS system is a distributed file storage system, so when downloading relevant data, it will be downloaded from multiple nodes at the same time, which is much faster than HTTP downloading from the central server. Everyone has used P2P downloads (such as Thunder, BitTorrent), and the IPFS download process is similar to this.

②Storage space has become very cheap. Since IPFS uses blockchain technology and uses Filecoin to encourage miners to share their hard drives, and IFPS removes redundant storage from the entire network (considering the entire network space, this will greatly save network storage space), future IPFS storage It will become very cheap (compared with our current cloud disks and various centralized CNDs).

③ Safety. It is currently difficult for centralized servers to withstand DDoS attacks. When a large number of access requests come from all directions, centralized servers will be paralyzed almost instantly. Students who have done operation and maintenance should be deeply aware of this. For example, every year on Double 11, I cannot sleep. In addition to technical students from Alibaba and Tencent, there are also children from the entire banking industry. Huge traffic may cause server downtime at any time. IPFS is inherently resistant to this kind of attack, because all access will be dispersed to different nodes, even the attacker himself is one of the nodes. To some extent, IPFS can even withstand quantum computing attacks.

④ Open. As we all know, Bitcoin is a decentralized and anonymous data currency. These characteristics make Bitcoin uncontrollable and transactions cannot be tampered with. IPFS is also built on a decentralized distributed network, soIFPS is difficult to be centrally managed and restricted. The Internet will be more open.

『三』What does it mean that the bat token has expired

Nowadays, the more common understanding of Token is to regard it as "Tradable proof of equity certificate", referred to as "pass". Although this definition is relatively accurate and gradually gaining acceptance, it is not familiar to those outside the field. The existence mechanism of Token itself is still highly controversial.

What does token mean (what does the error token expired mean)

This article will start from the relationship between token and blockchain, and explain the process of token formation and the source of token value. Analyze issues such as the relationship between , Token and equity.

1. The relationship between Token and blockchain and its definition

Blockchain technology can be used to store two types of information that cannot be tampered with: one is to describe and define various types of information. Information about resource (asset) status. For example, a person's credit record, a commodity, a real estate, a literary work, etc.; the other is information describing the asset transaction process*. In general:

1. Token must exist and only exist in blockchain projects with transactions, and serve as the basic unit of transactions.

2. Owning a Token is equivalent to having the right to claim certain types of resources on the blockchain. For example, owning BTC token is equivalent to having the right to transfer BTC. Owning eth tokens is equivalent to having the right to transfer out eth or pay transaction fees or create smart contracts. Owning an eos token is equivalent to having voting rights and the right to use a certain amount of computing, storage, and bandwidth resources.

3. From the perspective of case analysis, there are projects that only save the first type of information, such as the application of traditional Internet, banks, and governments in international trade, commodity traceability, and notarization. Although it is not necessary to use Token in such projects, from the perspective of the blockchain economy as a whole, both types of information are indispensable. Therefore, blockchain and Token have a symbiotic relationship.

*Note: Bitcoin’s UTXO model means that at the specific implementation level there is only transaction history and no account balance. However, from an abstract perspective, Bitcoin still has two types of information: balance and transaction records.

2. The formation of Token

In blockchain projects involving transactions (or value transfer), transaction information cannot be tampered with and is open to the public. It can have the meaning of value transfer without the need for third-party supervision. The case description is as follows:

"Alice gave Bob a flower" is a text message.

In a non-blockchain environment, only face-to-face transactionsOnly in this sentence can it convey valuable meaning, because both parties to the transaction can clarify the implementation of this sentence face to face. However, without the supervision of an intermediary, Alice said this sentence to Bob face-to-face. Because ALICE can deny or tamper with the content of her speech at any time, this sentence does not have the effect of value transfer.

In the blockchain environment, all participants must first reach a consensus on two points before sending information: 1. A consensus on the meaning of the information, such as the type of flowers in the above text information, and the number of flowers to send. time limit, etc. (Because the example involves off-chain entities, for the sake of simplicity, it is assumed that the on-chain and off-chain data are supported by fully credible oracles and are real information that cannot be tampered with). 2. If the first article is violated, punitive measures will be taken, such as credit deductions, monetary penalties, or even the permanent exclusion of dishonest persons.

Based on this consensus, after Alice signs and sends the above text, if there is no actual action. Then, with the confirmation of non-tamperable information, all participants will know that Alice is a dishonest person in the infinite future. And will use punishment mechanism to punish her.

After abstracting the above text, we assume that the purpose of this blockchain project is to record Flower transactions and issue Flower Tokens. Each Token represents the right to claim a flower. Then the above text information becomes structured information:

“A transfer 1 unit Token to B”.

At this point, we can see that in the blockchain projects with transactions, whether there is a special Token variable designed; whether there is a wallet that can transfer Token; whether there is a wallet that can be traded in the secondary market Token; Token exists naturally and objectively.

3. The value connotation of Token

From the above analysis, we can see that the entire value of Token comes from consensus. The value that participants assign to Token represents the right to claim resources. *For Token market value analysis, different projects should adopt different analysis models and frameworks based on their economic models.

Note: Consensus in a narrow sense is an agreement written in the system that all honest nodes must abide by, such as EOS’s right to claim computing resources; consensus in a broad sense also includes some people’s opinions on the use of Tokens Agreed, for example, 1Btc does not represent any resources at the ecological governance level, but gradually more people are willing to exchange Btc for more types of economic output or legal currency.

1. The value source of Token:

(1) The data structure of Ethereum ERC20 tokens is unified, but the market value of Tokens in different projects is completely different. Excluding those blocks ERC20 issued by chain technology companies, just look at traditional companiesToken applications can more clearly see the source of Token value. Taking Cindicator as an example, the project now provides robo-advisory research signals of different levels and richness, and uses the number of Tokens (CND) held as the threshold for Token holders to use corresponding services. The value of Token is entirely determined by the value of the project party itself in the field of robo-advisory.

(2) The value given to Token is not just the founding project party, but should be attributed to all ecological participants. In other words, what Token represents is determined by changing groups and their changing consensus. For example, the officially assigned value of EOS ERC20 Token has the right to be mapped to the holder distribution table in the EOS.IO system at a 1:1 ratio. After mapping, ERC20 Token no longer has the officially assigned value. But this token will not disappear. If the holder gives it a new token, such as the EOS Creation Holder Commemorative Token, then it will have a new circulating meaning.

2. The relationship between Token and stocks:

(1) There is no necessary connection between Token and equity. Whether Token can represent the holder’s rights and interests in the company depends on the currency project The company decides. But so far, Token can still be transferred freely (at any time and in any quantity) around the world. There is no project that completely limits the conditions, circulation scope, disclosure content, etc. of Token between different transferors. Therefore, it is actually still related to securities. Big difference.

(2) Under the blockchain economy, more and more economic activities will be released from large enterprises and governments, and will be completed by small businesses and individuals coordinated by smart contracts in the market and business environment. . In such a future economic situation, this article believes that for enterprises, being oriented by ecological rights and interests will be more in line with the interests of the company than being oriented by corporate rights and interests. In other words, Tokens representing ecological value will greatly squeeze the survival space of stocks. But as long as the company's organizational form remains, stocks and tokens will still be in a symbiotic state. It is worth noting that at the technical level, the recording and transfer of stocks may also be completed using blockchain technology.

Attachment, analysis of several translations of Token

According to Wikipedia’s explanation, from the perspective of economic value, the first meaning of Token is a small metal plastic that can be used instead of money. Discs are “tokens”, such as chips in a casino. The second type of meaning is quasi-money, that is, tokens, medals, temporary currencies, etc. other than coins or banknotes; the third type is vouchers and gift cards that can be exchanged for goods or services. On the other hand, from the perspective of information technology, Token refers to an object (Object, computer terminology) that can operate certain types of computing resources.

Token is now mainly translated into currency, token, certificate, etc. First of all, we should be cautious about using Tokenthe tendency to treat it as currency. One reason is that currency, as a general equivalent, has legal validity, can be used unconditionally within a country, and has the complete functions of currency (measure of value, medium of exchange, and store of value). Token does not have the function of unconditional use and value scale function, and logically does not have all the functions of currency. Another reason is that "coin" makes people preconceptions that Token represents money, which greatly limits the scope of Token's meaning. It is easy for people to ignore that Token can be the unit of all on-chain asset transactions and can represent all on-chain assets. Right of claim.

The full meaning of token is a negotiable proof of equity certificate. It is the most accurate and gradually recognized translation, but people outside the field are not familiar with it. As for tokens, literally speaking, "generation" refers to the certificate of claim to a certain type of assets or resources; "coin" refers to circulation. For example, the game currency in our daily life means that one can enjoy the voucher for using game facilities; the other means that the game currency can be exchanged with others. Therefore, the translation of token is actually synonymous with pass and can be used interchangeably.

『四』Why has the storage space of Interstellar Space IPFS become cheaper

Since Interstellar Space IPFS uses blockchain technology, Filecoin is used to encourage miners to share their hard drives. , and IPFS removes redundant storage from the entire network, so compared to our current cloud disks and various centralized CNDs, IPFS storage in the future will become very cheap.
