Ⅰ What should you pay attention to when choosing a blockchain project?

In the bear market of blockchain, how to find truly valuable blockchain projects? The editor will explain from the following aspects:

1. Use the Blockchain Security Technology Testing Center to see if it is a pyramid scheme coin or an air coin

Any project regardless of concept is boasted How advanced, how exaggerated the propaganda slogans are, but when it comes to the essence, it still depends on technology. Blockchain projects without technology are like the emperor's new clothes. They need a mirror that reflects the emperor's new clothes - blockchain Security Technology Testing Center.

Ulord public chain technology provider Tianhe Guoyun is one of the important sponsors of the Blockchain Security Technology Testing Center. The code audit function it provides is for the Blockchain Security Technology Testing Center to identify blockchain projects. A weapon for both good and bad. Code auditing uses machine learning and artificial intelligence to establish a knowledge base for automatic auditing of blockchain codes. It can improve the efficiency of code auditing and solve the security issues of smart contracts. The blockchain code audit business prevents digital asset security incidents by conducting quality assessments on blockchain projects, exchanges, wallets and smart contract codes, and provides services such as code revision measures and security protection deployment. It is reported that in addition to automatic auditing, Tianhe Guoyun's blockchain code audit can also customize expert team projects to conduct comprehensive audits to help investors identify "fake projects" to a greater extent.

2. Look at the blockchain project team

The blockchain field can be regarded as a comprehensive field, involving cryptography, mathematics, economics and even social management. Subject. We have a reliable team. As I mentioned above, the Ulord project has brought together a large number of high-level R&D and operations personnel.

3. It is not just a hot concept, but also its application.

There are many startups in the blockchain field. If you want to become a few high-quality projects that are widely recognized, just speculating on concepts or theories will not work. Only projects with hematopoiesis capabilities and practical implementation are good projects.

The current application DAPP Ushare based on the Ulord public chain has been officially launched on October 15th. Ushare is the world's first decentralized experience value sharing platform and the first DAPP based on the Ulord public chain. Through a decentralized consensus mechanism, we will build an open, fair and just content evaluation system, encourage high-quality experience producers and experience sharing disseminators, and allow the value of high-quality experience to flow.

There are also nearly a hundred teams and projects that are negotiating and cooperating with the Ulord public chain.

4. Communities all have autonomous attributes

Whether the community has the attributes of a DAO (distributed autonomous organization), this is naturally suitable for blockchain,

About the governance of the community. Whether it is the operation model of the community or the organizational form of the developer community, it is actually in a process of quantitative change to qualitative change. Everyone has realized the important role of community.

Ulord adopts a community autonomy model in which “everyone can participate and everyone can contribute to the ecology”.

We will have some new community governance models, including collaboration among some developers, and large-scale open source community collaboration models will be born and flourish.

The incentive system mainly includes three aspects: first, participation in accounting; second, contribution to network resources; third, participation in community building. As mentioned above, in the accounting part of our entire budget system, the POW + PoS part accounts for 60%, the code contribution level of participating in the open source community accounts for 10%, and the remaining 10% is used as an incentive for community operations. Therefore, we hope that more people can participate in the construction and promotion of Ulord. We hope to build a platform, but the dividends obtained from this platform should be shared with everyone to the greatest extent. This is also fundamentally different from Internet products.

Ⅱ What is Lightning Bitcoin

Lightning Bitcoin is not well-known yet. That is because it is a fork of Bitcoin. Many users in the currency circle are Instinctively aversion to such tokens. Forked coins have now become synonymous with making money and running away. But one thing you may not know is that all Bitcoin forks can be called currencies in the eyes of foreign regulators. The U.S. SEC only recognizes Bitcoin and Ethereum as currencies because they have not conducted ICOs in public channels. Correspondingly, these forked coins are considered currencies. And Lightning Bitcoin is the only fork coin that does not have pre-mining. You can imagine that Bitcoin is a 100 banknote issued by a bank, and various forked coins are equivalent to banknotes of different denominations issued by this bank. You may not understand the valuable value here. When it comes to physical circulation, if you are a fork of Bitcoin, it will easily pass government compliance. To put it simply, the reason why Big Prince BCH can open up the physical circulation link in Japan so quickly is that it is a fork of Bitcoin.
Then why do I say that Lightning Bitcoin is a great monetary experiment? Because of the on-chain governance mechanism implemented by Lightning Bitcoin, practical issues are democratically decided through voting through code. We compare Lightning Bitcoin to a free economy with three major stakeholders: developers, miners, and currency holders.

So far, no blockchain project can effectively govern these three. Why? The reason is very simple. Often an ICO project has the largest number of developers and currency holders, and even the miners are the same group of people. This is easy to understand, so why should he give up the greatest benefits to holders who pass the ICO? , this is obviously not in line with human nature. Why Lightning Bitcoin dares to do on-chain governance is because it has to do with the issuance method of Lightning Bitcoin. LBTC's "on-chain governance" this time is another attempt at "decentralization", and it is also very eye-catching. The DPOS mechanism determines that there are 101 nodes in the network. At the same time, unlike POW, the choice lies with the currency holders.In the hands of the node, these nodes will be voted by currency holders. When the nodes do not act, users can also vote to be kicked out of the network. According to the content of last week’s weekly report, LBTC’s block browser has also added this function, which can check the node operation in real time. It also paved the way for LBTC’s “on-chain governance”. In the LBTC system, all currency holders can decide whether to stay or leave project development proposals by voting, and all organizational members can participate in the organization’s decision-making and operations. In addition, the standard of 5,000 locked up after this lightning node election also guarantees The node is both a mining pool and a currency holder. This better balances the relationship between miners, developers and users and forms the basis of an autonomous organization.

Ⅲ What are the financial scams in blockchain and how to spot them

With the continuous development of social economy, in our real life, we will always encounter various scams. Various problems, especially scams about blockchain fund fraud, make every one of us investors hate this very much. Next, the editor will lead you to take a look at what happens when we encounter blockchain When there are financial scams, how should we detect them and how to prevent these scams.

To sum up, we can clearly know that blockchain funding scams often have these types of scams, so when we find that these types of scams exist, Sometimes, we must not believe it, and in the process of investment, we must invest in regular big brands and big projects, and do not casually believe in the high returns that someone brings to us. This is all Fake.

Ⅳ A review of the top ten most profitable blockchain APPs. Making money by mining is so simple!

As network technology becomes increasingly mature, the word blockchain is mentioned by more and more people. In 2018, blockchain became the first choice project of many investors, and the number of mobile blockchain software is also gradually increasing. From dozens in 2013 to hundreds or even thousands of blockchain companies in 2019, we can see how hot the blockchain market is. In the minds of many friends, blockchain is something that allows one to make money. Yes, blockchain does allow many people to make money, but now there are also many unscrupulous fake companies in the blockchain market. In the name of blockchain, it is actually a deceptive business. So friends, when playing with blockchain, you should also keep your eyes open and choose a formal and trustworthy platform!

Today I have collected and sorted out 10 recently popular blockchains for you. Chain software, these platforms are all real and reliable, and each platform has a large number of users. If you are also a friend who likes blockchain, then don’t miss the content I bring!

After understanding the blockchain, let’s start the text. Content, bringing you an inventory of the ten most profitable blockchain software↓↓↓↓↓

IV What is LBTC

Analysis of the advantages of LBTC from the code mechanism level
DPOS mechanism
In recent years, due to the waste of POW resources, the instability of block generation, and the existence of computing There are problems such as force attacks. Although POW is recognized as the most widely used and safest consensus mechanism, there is still a great risk of being attacked for blockchains that do not have enough computing power in the entire network. More and more consensus mechanisms are being proposed and applied to blockchain projects for trial and experimentation. DPoS is one of the current mainstream consensus mechanisms, and LBTC adopts this mechanism. DPoS ensures that the voting rights are in the hands of currency holders, so currency holders will be able to vote whether to pass the proposal, thereby deciding the development direction of the project. This also means that the development direction of the project depends on the people who care about the project itself, and the power of public wisdom will promote the better development of the project. At the same time, the advantages of the DPoS mechanism include the absence of computing power attacks, strict compliance with block time, and resource saving.
LBTC’s DPoS advantages
LBTC’s DPoS mechanism also has its own project characteristics: The number of LBTC nodes is 101. Compared with 21 or 51 nodes, currency holders can be in the LBTC wallet at most once. It can vote for 51 nodes, further reducing the risk of centralization; LBTC can stably generate blocks in 3 seconds, coupled with the block size of 2M, ensuring that LBTC is 400 times more efficient than Bitcoin, and the transaction speed per second can reach More than 2,000 transactions; The most important and innovative thing that is different from other projects is that the DPoS mechanism of LBTC has the rule of irreversible blocks. When a block is produced in a round and the number of block-producing agents reaches more than 90%, or two consecutive blocks are produced, and the block-producing agents are greater than 70%, the first block of the previous round can be considered irreversible, thus preventing forks.
LBTC’s defensive measures
In addition to being based on the DPOS consensus mechanism, LBTC has other technical highlights.
First of all, LBTC can prevent [replay attacks]. What is a replay attack? Each Bitcoin account will have a corresponding number of LBTC based on its Bitcoin balance. If the addresses, private keys, algorithms, etc. on each chain are the same, and the transaction formats are exactly the same, transactions initiated on one of the blockchains can be re-broadcast on the other blockchain, and possibly also Get confirmation. This is a "replay attack". Simply put, when a user transfers LBTC, BTC may also be transferred away at the same time. LBTC modifies the hashing algorithm in transaction signatures. In the hash algorithm, LBTC has a new "LBTC" field. The HASH generated by LBTC and BTC will be different. LBTC and Bitcoin do not recognize each other's transactions, thus preventing replay attacks.
Secondly, prevent [fake mining]. There is no concept of voting and balance in Bitcoin transactions. For the maximum stability of LBTC, a new one by O is added to Coinbase transactions.P-return constitutes OUTPUT, and OP-RETURN data consists of three fields: Publickey, Time, and Sign (Time). Time represents the timeliness of the transaction. Publickey verifies Sign (Time), which is the principle of asymmetric encryption algorithm to prevent forgery and mining by others. LBTC has 101 nodes. Assume that the attacker has 30 nodes. If the remaining 71 nodes are forged, other nodes can mistakenly think that the attacker's chain is the longest chain and generate blocks. This is a forgery mining attack.
Third, prevent [Double Spend Attack]. A double-spend attack is when a sum of money is spent twice, which can also be called a double-spend attack. For example, BTG, which has attracted widespread attention before, recently suffered a 51% attack. A malicious miner obtained at least 51% of the computing power of the BTG network, temporarily controlled the BTG blockchain, quickly withdrew the currency after recharging to the exchange, and then reversed the block, successfully implementing a double spend. Due to the irreversible blocks mentioned above in LBTC, when the transaction of the LBTC block is confirmed, it will be impossible to roll back, in order to achieve the purpose of preventing double-spend attacks.
Fourth, [Multi-threaded execution]. In the transaction consistency and legality check of LBTC, the data that can be merged and integrated is merged and executed using multi-threads, which greatly improves the transaction efficiency and enhances the performance of LBTC.
The code logic of LBTC
In addition, in terms of code logic, LBTC is divided into protocol layer, consensus layer and application layer. When it is necessary to transmit value, the transaction is completed through the protocol layer link and the consensus layer. This process can not only be used as an exchange of value, but also act as a value intermediary in the three-party connection. The application layer is mainly implemented based on smart contracts. In the future development route, LBTC will implement the gateway function based on smart contracts. The payment gateway implements asset issuance, asset trading, legal currency exchange, on-chain interaction, etc.
That’s why LBTC can be so confident in saying that it is going to be a global value Internet protocol. Through the payment gateway, it can realize the exchange between any currency, not only between currencies, but also between legal currencies and digital currencies, and between legal currencies. Isn't this very convenient? With one-click conversion, you can buy ETH with Vietnamese dong and transfer it to your British cousin who is far away. She was disgusted by it and immediately changed it to EOS. After a second, it was converted to pounds. There is no need for unnecessary conversion steps. It is done in one step. Isn’t it wonderful? ? With this analysis, it is actually quite reliable to analyze LBTC from the technical code level. However, compared to those experts, the editor will not fool you. Whether LBTC can realize a decentralized value Internet protocol in the future, paying attention to the code will be a more intuitive way. (LBTC’s Github: https://github.com/lbtcio/lbtc-core)
How to use the gateway?
Next, let’s talk about the specific implementation of the gateway’s “conversion and circulation”, which can be roughly divided into three types:
First, when the LBTC system sets up a good networkAfter closing the technology, using the gateway as a bridge, user A can exchange any currency into LBTC, and then send it to any user B who wants to send it, and user B can exchange LBTC into any currency he needs. This sounds like Doesn’t it look like everyone’s usual operations on the exchange? I think this is one of the reasons why LBTC proposed to be a "decentralized exchange".
Second, user A can store funds in a gateway trusted by user B and transfer them to user B through the gateway.
Third, since LBTC will provide the function of “any user can issue Token” in the early stage of gateway construction. Therefore, in the LBTC system, if user A has a good reputation, is recognized by everyone, and issues his own A Token (of course, this should include the assets realized by asset mortgage on the chain), A can put his A Token For user B’s currency exchange. User A can also redeem the A Token exchanged to B later. A is the gateway role in the transaction process.
In the process mentioned above, the functions of asset issuance, asset trading, legal currency exchange, and on-chain interaction are respectively realized.
The use of the gateway is similar to the function of a bank, and it can mainly solve the problem of cross-border transfers. Coupled with LBTC's high TPS and low handling fees, cross-border transfers will become very convenient. For example, if you need to remit money from China to the United States, you need to remit RMB to the LBTC gateway in China. Then the gateway in the United States will receive the LBTC from the Chinese gateway, convert it into US dollars, and forward it to the account in the United States. In the above gateway system, it can be concluded that both parties to the payment do not need to join the network, they only need to trust the gateway.
Although gateways solve the problems of slow speed and high handling fees of traditional transfer payments, they also face new problems.
Then here comes the problem
In addition to the standard-compliant institutions or project parties invited by LBTC to become gateways, ordinary users, in addition to mutual transactions between acquaintances (in fact, this behavior is more likely to For lending, if it is just a transaction between acquaintances, it will form a small independent network). How to prove that the gateway is a trustworthy institution or individual?
How to promote LBTC’s gateway to cooperate with large institutions is obviously a problem before the team. Ripple has developed relatively maturely and has currently cooperated with Japan's MUFG, Australia's Westpac, and the UK's Standard Chartered Bank. With Ripple, Stellar Lumens and other payment digital currencies in the forefront, LBTC wants to take its own path. , more features are needed, which can be expected in the later smart contract road planning.
However, Ripple has also been accused of being too centralized because of its distribution method. LBTC has 101 nodes because of the DPOS mechanism it adopts, and because it is a forked currency, it is distributed to Bitcoin holders on a 1:1 basis when it is issued. , this can be said to be the inherent advantage of LBTC - it has broad dispersion, ifIn the future, if we can gain support and recognition from the public and reach a consensus, we will have the inherent advantage of wide distribution.
In addition, during the process of putting assets on the chain, how to prove that the assets actually exist in reality and can be used as collateral? In addition to large institutions such as banks, small networks will also have their existence. The asset certification of assets on the chain is an extremely important part. If there are no rules and certifications, it is very likely that the gateway will run away or a false gateway will occur. Although the gateway is exemplified as the "Taobao" platform, in theory the platform cannot control the merchants' buying and selling content, but the platform has supervision over the quality of the goods, otherwise it will inevitably cause chaos.
Decentralized Exchange
Going back to the first point, let me talk a little bit about my thoughts on decentralized exchanges. At present, mining farms and centralized exchanges are the protagonists of the early development of blockchain. With the rise of more and more exchanges, centralized exchanges have fallen into manipulation scandals, etc., which have brought growth to the gains of decentralized exchanges. Comes space. Decentralized transactions are very likely to truly bring value to the blockchain field and become the real protagonist of the blockchain era. LBTC relies on gateway technology to realize a decentralized exchange. In LBTC's decentralized exchange, users' own coins will be kept by themselves, preventing the possibility of coins being lost in centralized exchanges. It can also prevent system transaction opacity, operational and technical risks. According to the previous Gateway interview introduction article, LBTC will also join forces with reliable project parties to list it on the exchange to benefit all community members. Generally speaking, the development route of LBTC is relatively clear, and its goals in the payment field are also very clear. Take it, friends, and the future is promising!

VI Which blockchain projects are worth investing in now?

Nowadays, blockchain has been criticized by many players. When it comes to blockchain, the first reaction of many people is that they are scammers. In fact, blockchain has now begun to study practical applications in many industries, such as logistics, medical care, etc. If you invest, you can start with application implementation, but the cost is too high and the technical requirements are relatively high. The other is mining. Although the income will be slower, it is still relatively stable. Don't believe in all kinds of stocks with high profits and high returns. The greater the temptation, the deeper the pit.

Ⅶ What kind of blockchain projects are suitable for ordinary people to invest and can also make money

A formal financial solution that applies blockchain can double your investment A blockchain project must have the following points at the same time: (Take out a small book and write it down)

1. There will definitely be coins, but they are not virtual currencies for speculation.

Why do blockchain projects have to have coins? What role does this coin play? Coins play the role of vouchers in the project and also play a role in circulation. In fact, paper notes can also play the role of vouchers and circulation. For example, IOUs, or even stamped IOUs, can be used as vouchers and circulation, right? able! However, notes can be forged, but things on the blockchain cannot be forged and are unique. thisThis is why blockchain projects need coins. However, it should be noted that this coin is not for speculation, but is complementary to the business. It not only has transaction attributes, but also has cash dividend attributes. Generally speaking, even if it is left untouched, it will not affect project operation and investment income. .

2. There must be an investment protection mechanism.

In other words, your income must be stable and sustainable, rather than based on speculation. I have never heard that you have to get the return on investment yourself. The so-called return on investment must be obtained without paying much cost. In other words, someone has to manage the business and actually do the work. Do you understand? Only in this way can your investment increase in value. This investment return mechanism is best protected by legal form.

3. Have a real business system and hematopoietic ability.

Complete business entities and hematopoietic capabilities are the basis for whether all investments can gain value! Without a complete business system and hematopoietic capabilities, any investment will not achieve stable, reliable and sustainable value-added.

If you want your investment to be insured and safe, these three points are essential. If you have these three points at the same time, it will be a matter of time before you make money. Without these three points, your investment will basically be in vain.

Is the blockchain investment platform a scam?

Blockchain investment itself is not a scam, but its price formation mechanism is opaque, which can easily cause huge losses to investors and lacks supervision. , and therefore may become a scam. If investors are defrauded due to blockchain investment, they can defend their rights against the exchange and the project party. Any behavior that constitutes fraud or other crimes should be reported promptly, and the judicial authorities will investigate the corresponding criminal liability.
[Legal Basis]
Article 3 of the "Criminal Law of the People's Republic of China" If the law expressly stipulates that the act is a crime, it shall be convicted and punished in accordance with the law; if the law does not expressly stipulate that the act is a crime, it shall not be convicted and punished. Article 13 All activities that endanger national sovereignty, territorial integrity and security, split the country, subvert the power of the people's democratic dictatorship and overthrow the socialist system, undermine social and economic order, infringe upon state-owned property or property collectively owned by the working people, and infringe upon the private rights of citizens All property, infringement of citizens' personal rights, democratic rights and other rights, as well as other behaviors that are harmful to society and should be punished according to the law are crimes, but if the circumstances are obvious and minor and the harm is not great, they are not considered crimes.
