1. What is the mirror network MW and what is its connection with IPFS?
A: As the underlying transport protocol, IPFS has the characteristics of high efficiency (obtaining file data nearby), low cost (saving bandwidth), and security (decentralized storage, which helps to prevent hacker attacks). It is essentially a distributed storage, which can turn a file into a hash value. With IPFS technology, the files you upload, whether they are videos or photos, will be broken and encrypted. In the IPFS network, the hash value of the same file is unique. The blockchain only needs to store this hash value to store the entire file.
Mirror network MW is a mature project that has applied IPFS technology to actual storage. It has been working on for three years with nearly 1 million lines of core code. It has learned from the technical experience of IPFS, Alibaba cloud OSS, Stoij, etc. at home and abroad, and uses peer-to-peer P2P network, DHT distributed hash table, data encryption fragmentation and IPFS Network protocol, multi-chain incentive mechanism block exchange and other technologies to build an easy-to-use and available distributed storage network.
At the same time, blockchain combined with distributed storage is also the only industry that can combine mining with practice. While consuming a lot of computing resources, it can also be a commercial storage network beneficial to the society.
2. Mirror network includes future Internet framework, high-performance innovation system and high-security and reliable data. What is its design principle?
A: What mirror network MW can do are as following:
1. Building an open distributed blockchain storage network to form a multi-chain ecology with various existing networks and public chains to complete data and value transmission.
2. The spare storage resources of the enterprise and individuals are organized into distributed storage network. All kinds of public chain, storage network and personal node can be deployed and operated.
3. Building a global distributed cloud storage compatible with IPFS, public cloud storage and private cloud storage.
Secondly, we also need to talk about chain framework. In the public chain, the mirror network MW is an open blockchain with distributed storage system. We will also build an alliance chain in China and build a distributed data center DDC to provide users with cheap, secure and highly private storage services. We can also supervise or audit enterprises and governments to a certain extent in some specific fields.
Last but not least, we can also provide data backup, verification and query services for other public chain (open source chain) .
3. MW aims to build an easy-to-use and available distributed storage network. What advantages does the mirror network MW have compared with mechanisms such as PoW and PoS mechanisms?
A: We all know that bitcoin is a PoW consensus mechanism, and PoW (workload proof) is an essential attribute of blockchain. It is used to increase the cost of generating effective blocks and make the operation of attacks on the network more expensive. Just like bitcoin, it needs 51% computing power to attack, which is a high cost, but this consensus mechanism consumes a lot of power resources: for example, bitcoin mining consumes nearly 1% of electric power of human beings every year, while it does not produce any value to the real economy.
Next, let’s talk about PoC (space capacity proof). It forms a consensus by storing the amount of data, and because it stores actual data and files, it is helpful to the real economy. But in the past, we need to insert data (P disk) in advance to obtain rewards. What is the real PoC? I don’t think that can be proved by occupying space, and hardware information can be read completely. The cloud machines just need to be prevented from doing evil by cloud computing and all devices can be authenticated by technical means, which is what the mirror network MW is doing.
The mirror network MW adopts a new solution of PoC + DPoS, which combines all the single disk space into a large information space. We only need to store in one space, and we don’t have to worry about who worked and who didn’t work. The only way to reward is to provide the size of the space capacity. In this way, the problem of allocation is solved. In addition, with the unlimited growth of this information space, there is no limit to do storage business. It is obvious which has more advantages in the market with unlimited capacity or limited capacity.
4. At present, MW test network has been on-line for more than 3 months. What achievements have been made?
A: MW released a data report 90 days after its launch. The report shows that until 12:00 on July 16 (UTC + 8), the block height of the mirror network MW is 12650, the number of global nodes is more than 7606, the storage space is 75303TB, the number of network addresses is 11950, the number of transfer transactions is 30927, the average number of transactions in blocks is 281, the version is updated 6 times, and the official website UV25584, with nodes all over China, the United States, France, Germany, Austria, Switzerland, Poland, Japan, Korea and so on.
Now our data on the chain has a new breakthrough, I believe that with the further expansion of the network, it will be better.
5. With the launch of the main network of Filecoin getting closer and closer, when will the miners make the best layout, or how can they make the most of the profits?
A: First of all, bitcoin has been finished with reducing by half. The cryptocurrency industry needs new forces to promote it. IPFS has been on the market for five years. With the iterative updating of technology, it has been used in some business scenarios. Now, Fil’s main network is about to go online, which is an excellent booster.
Moreover, the concept of distributed storage is good and easy to be implemented. It can be well combined with the development direction of future society, whether it is 5g or the Internet of things. MW believes that this is only the beginning, and there will be a bigger market scale explosion in the future.
6. Recently, there is a saying “Fil gold, MW silver”. MW has recently been regarded as a new wave of investment. How is its income and How can users get MW?
A: Part of the reason why MW went online this year is because Fil. They both use IPFS transmission protocol for storage with different technical directions, but the miner group is the same, that is to say, the logic of investment is the same. At present, the income of MW will be 45 times of MW per day if the equipment is 12 disks and 96T of space capacity. In addition, there is a single explosion Block probability, if it is a second-hand device, the payback cycle is about 6 months, which is relatively benign, just like bitcoin.
At present, you can participate in mining, or OTC trading directly.
7. At present, the image network MW is vigorously promoting DDC (Distributed Data Centers). What are the advantages of DDC compared with traditional data centers?
A: At present, the concept of DDC is really popular indeed. We proposed the concept of DDC at the beginning of this year, and we are sparing no effort to promote and implement it. In order to make you understand DDC better, we also have a very clear definition of DDC.
DDC (Distributed Data Centers), according to the definition of distributed storage, is to use the network to connect thousands of storage servers to form a virtual super storage server, and complete the problem solving of super large scale that single storage server cannot complete. DDC not only makes a single storage server form a virtual super storage server, but also organizes multiple data centers to form a multi-center service network.
At the same time, the blockchain provides a guarantee for the operation of the distributed data center. The operation data of each data center and node storage server are recorded in the chain through the blockchain account book, realizing the functions of workload proof, data distribution adjustment, data archiving, multi-role management, etc..
Take 96,000T data storage scale as an example:
Traditional IDC room: single data center, storage equipment costs over 30 million, single user service, more spare resources.
DDC: multi data center, node clustering, almost zero cost of storage equipment, flexible business deployment, strong scalability, light assets operation and investment in data center with scale of 100 million.
DDC uses personal storage resources, public chain storage resources and operators’ storage resources to build distributed city node commercial storage applications and create large-scale cold data storage.
8. At present, the mirror network MW has been able to apply IPFS technology to actual storage maturely. What is the next development plan?
A: the mirror network MW aims to achieve an “easy-to-use, available” storage system. At present, IPFS technology can be used for file storage in MW system, which is extremely secure, private and permanent. Now everyone can pay MW to use storage service.
The distributed data center (DDC) built on MW has established a strong foundation for data application. In the future, MW will deploy multi-country nodes to build a multi regional distributed data center.
At the same time, we also hope that the global storage class, open source public chain and enterprises and individuals with storage resources can join the mirror network MW, providing a solid foundation for the future storage mode.
