Blockchain Technology Business Forum
this is a gathering place for blockchain enthusiasts, with tens of thousands of blockchain practitioners and many top experts in the instry. Blockchain brothers are not only a platform for technical exchanges and answers to difficult and miscellaneous problems, but also innovative incentives and project training to drive the talent cultivation and development of the blockchain instry, and continue to provide rich instry resources to truly serve blockchain talents.
firstly, the development of blockchain is still at an early stage; secondly, the uncertainty in the blockchain instry is manifested in the aspects of supervision and so on. Although many institutions of the national government are committed to the establishment of blockchain instry standards, blockchain as a new thing, to formulate relevant laws and regulations, still need to be discussed and studied by many parties
when it comes to blockchain forums, there are Babbitt, blockchain home, coin world, Zhiqu chain and so on. Blockchain forum which is good, you need to practice more, after all, everyone has different views. I hope the above content can help you.
Babbitt and bitcoin house in China are well-known information websites
European crowdfunding is an attempt of "blockchain + crowdfunding" project in China
NASDAQ is a leader in blockchain applications.
nowadays, many swindlers use the concept of district fast chain to hype, and then pull investment to cheat money. I really don't know what's the use of these people investing in an anti cheating system, which doesn't generate value.
1. Banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking instry. Indeed, UBS, a Swiss company, and baecelays, a British company, are trying to use blockchain technology to improve payment terms. Some other banking companies even said blockchain technology could save $20 billion in intermediate costs
therefore, it is not surprising that banks, as financial service giants, have become the growth force of blockchain venture. Payment and transfer
recently, the world economic forum wrote in Forbes magazine that decentralized payment technology, such as bitcoin, may change the "business structure" of the transfer instry that has not changed for more than 100 years. Blockchain technology can avoid complex systems and create a more direct payment process between the payer and the payee. Whether it is domestic transfer or cross-border transfer, this method has the characteristics of low price, fast speed, and no intermediate fees. Abra (above) is a start-up enterprise that uses blockchain technology for global bitcoin and blockchain based transfer
3. Network security
although the system of blockchain is public, advanced encryption technology is used in the process of data exchange such as verification and transmission. This technology not only ensures the correct source of data, but also ensures that the data will not be intercepted in the intermediate process. If the application of blockchain technology is more extensive, the probability of being attacked by hackers may also decrease. Therefore, people think that blockchain system is more secure than traditional system. One of the reasons why blockchain system can rece the traditional network security risk is that it relieves the demand for middleman
"eliminating middlemen not only reces the potential security risk of hacker attacks, but also reces the possibility of corruption," Goldman Sachs wrote. Guardtime (above) is an Estonian start-up company, which mainly studies instrial network security solutions based on blockchain technology
4. Academic record and academia
holbertson school, a California software skills program, announced that it will use blockchain technology to identify academic credentials. This will ensure the authenticity of holbertson school students in course identification. If more schools adopt such transparent certificates, transcripts and diplomas, academic corruption will be greatly reced, not to mention the labor verification time and paper document cost
5. Elections
at the University of West Virginia, the student union is considering whether to use a voting platform based on blockchain technology to conct school elections. If such a platform is used, students can vote with mobile devices, and the voting results will be included in the public system, so the voting is completely safe. One student who supported this way explained that the vote "can never be modified or deleted by us - programmers, school administrators or students."
Agora voting, a Spanish software project, uses encryption technology to improve the security of online voting. Several of their systems have also been tested in Spain. Recently, the leader of this project proposed several ideas to turn bitcoin and blockchain technology into voting applications, which are far from experimental
6. Car rental and sales
later last year, visa and DocuSign announced a cooperative plan to create specific solutions for car rental by using blockchain technology. In the future, car rental can be completed in three steps of "click, sign and open". The specific operation is: customers choose the car they want to rent, and then the transaction will be uploaded to the public account of the blockchain; Then, the customer signs a lease agreement and an insurance agreement from the driver's seat, and the blockchain will upload the information in real time. It is not hard to imagine that this leasing model may also be applied to the field of car sales and car registration
7. Network communication and Internet of things
IBM and Samsung are working together to realize an idea called adept. Adept uses blockchain technology to build the pillar of decentralized Internet of things. Coindesk said that with adept, the decentralized P2P automatic telemetry system, the blockchain can become a public system for many devices, and there is no need for a central hub to mediate the communication of various devices. After removing the central control system and identifying each other, the devices can automatically communicate with each other, manage software updates, bugs, or energy consumption
other companies are also committed to integrating blockchain technology into the Internet of things platform. For example, filamen, which uses blockchain technology to build a decentralized network for sensor communication, announced that they have obtained US $5 million investment in round a financing, with the participation of Verizon ventures and Samsung ventures
8. Smart contract
a smart contract is actually a computer program that functions on the action of another object. Like ordinary computer programs, intelligent contracts are also an "If then" function, but blockchain technology realizes the automatic filling of these "contracts" without human intervention. This kind of contract may eventually replace the core business of the legal instry, that is, the business of drafting and managing contracts in the commercial and civil fields
for example, mortgage loans can be completed through blockchain technology and automatically executed every year according to the terms of the contract. Ethereum, a crowdfunding platform based on blockchain technology, not only provides decentralized applications, but also provides smart contracts. Some users have married with their smart contracts. Another company, hedgy, received $1.2 million in seed round investment from Tim Draper, Marc Benioff, boost.vc and sand hill angels earlier this year. The company uses smart contracts to build a platform for users to discuss the value of bitcoin
9. Prediction
blockchain technology may shake the whole research, analysis, consulting and prediction instry. Aug, an online crowdfunding platform, hopes to make a profit in a decentralized forecasting platform. The company said it would offer a service that looked like a gaming swap. The whole process will be decentralized, and the AUG platform will not only provide users with sports and stock gambling services, but also provide election and natural disaster gambling services. This idea actually goes beyond sports gambling and creates a "forecasting market"
10. Online music
many musicians are choosing blockchain technology to improve the fairness of online music sharing. Billboard reports that two companies are automatically solving licensing problems by paying artists directly and using smart contracts. Peertracks, which is still in its infancy, wants to create a new music streaming platform where users can pay artists directly without middleman's intervention. Peertracks also hopes to create more direct interaction between artists and users
ujo music, led by entrepreneur Phil Barry, claims that they are rebuilding the music instry on the blockchain. Ujo also hopes to solve the problem of streaming music and artist payment. In addition to streaming music, it is also expected that ujo will be able to better classify the artists and creators behind the songs by using intelligent contracts as the autonomous brain of the song list
11. Travel sharing
Uber and other travel applications seem to be on the opposite side of decentralization. This company is like a deployment center, using its algorithm to control its drivers and their charges. According to the report of blog, Israeli venture LA & # 39; Zooz wants to "go against Uber.". The company invented its own patented digital currency, which, like bitcoin, can be digitally recorded using blockchain technology. Different from the centralized network, users can call in LA & # 39; Find people with similar itinerary on zooz, and then use LA & # 39; Zooz's currency pays the taxi fare. These coins can be used for car hailing in the future. Users can get LA & # 39 as long as they allow the app to track their location; Zooz's digital currency
12. Stock trading
for many years, companies have been trying to simplify the process of stock purchase, sales and trading. Emerging blockchain technology makers believe that they can go beyond the past, realize the automation of the whole process, and improve security and efficiency. Overstock's subsidiary T & # Com wants to use blockchain technology to realize online trading of stocks. Overstock is already using blockchain technology to issue public shares, wired reported. At the same time, chain, a blockchain technology maker (mentioned above), is working with NASDAQ to realize the share trading of private companies through blockchain technology.
We have successfully developed a new yield farming proct, but before launching, I would like to explain a few concepts
when we developed Iearn, we had very simple choices: AAVE, compound, dydx, and fulcrum. Each proct provides a lending market for different assets. You can lend your assets and earn a passive income
then each project starts the war of stimulating liquidity. Compound fired the first shot with their comp token, and then everyone rushed in. Balancer soon launched BAL, mstable launched MTA, fulcrum launched BZX, and curve is ready to launch CRV Translator's note: the core mode of these projects to stimulate liquidity is similar: according to the amount of assets provided by users, get the original token of the additional issuance agreement in proportion; On August 16, 2020, curve launched CRV.)
however, this makes yield farming more complicated, and it is not enough to switch options only according to the deposit interest rate
now, the strategy will be complicated as follows:
- store Dai in compound and CDAI in balancer. Earn comp through Dai and BAL through CDAI, plus the deposit interest rate that Dai can obtain, and the handling charge of CDAI in the balancer trading pool Li >
- deposit Dai into curve, and then deposit the curve token into synthetix mintr exchange. Earn CRV through Dai and SNx through curve token; Plus the transaction fees available in the curve transaction pool Li >
- store Dai in mstable and mstable in balancer. Dai can get an interest rate and mstable token can get BAL in balancer protocol; Plus, you can earn fees from balancer's trading pool Li >
- save usdc into maker, cast Dai, and then repeat options 1, 2, 3 Li > < / OL >
and the above strategies are just some examples. A few weeks ago, the best strategy was to borrow bat from the compound market; Now we use compound as the lever of Dai. But next week, it may be the SNx pool that participates in curve
the common problem faced by all the above strategies is that the significance of these strategies is based on the value of comp, BAL, MTA, SNx, CRV, etc. And the price of all these tokens will fluctuate. This also means that all these strategies depend on the price information transmission mechanism. At the time of writing, there is no price information transmission mechanism for comp, BAL, MTA, SNx and CRV, unless you use the price in uniswap trading pool or balancer trading pool as an index; But once you've used it, be ready to drain your liquidity
the purpose of this article is to tell you that yield farming has become very complicated, and we expect it to become more and more complicated in the future. Therefore, we need to provide a new proct, not simply choose among these options, but cultivate new options (instead of trying to choose between these options, seeds these options)
