How Filecoin supports BSN's "cloud storage"

This article was originally written by Tony from IPFS Force Zone

With the continuous development of the digital age, multi-party data interaction has become a universal demand, and the emergence of blockchain technology provides technical support for trusted multi-party data interaction.
On March 4, the Standing Committee of the Political Bureau of the CPC Central Committee proposed at its meeting to "accelerate the construction of major projects and infrastructure that have been clearly defined in the national plan, and speed up the construction of new infrastructure such as 5G networks and data centers." The concept of "new infrastructure" was proposed, and subsequently "blockchain" was clearly included in the scope of new infrastructure.
Prior to this, Wu Hao, deputy secretary-general of the National Development and Reform Commission and director of the Regional Economy Department, also proposed to define the scope of new infrastructure as information infrastructure, integrated infrastructure and innovative infrastructure. Information infrastructure mainly refers to new technology infrastructure represented by artificial intelligence, cloud computing, blockchain, etc.

BSN plays a key role in information infrastructure. Through existing equipment conditions, blockchain underlying framework, artificial intelligence and cloud computing, it builds a new open infrastructure platform to provide developers with a one-stop blockchain application development and deployment environment.

The reason for the birth of BSN

• Opportunities of the times: The era of rapid development of the digital economy, the outbreak of the COVID-19 pandemic, and the opportunity of the transformation of new infrastructure to digitalization, informatization and intelligence. Pain points of end users:

• Enterprise endorsement service endorsement, continuous iteration of service technology, case implementation guidance

• Pain point for product and service vendors: low development and deployment costs

BSN Global Expansion

Since its establishment in August 2018, the cross-cloud, cross-portal, and cross-underlying framework blockchain service network BSN has also begun to show its edge, aiming to solve the high cost and technical difficulties of establishing a global platform. In the past two years, BSN has completed the various stages of R&D deployment, testing, and commercial launch. Starting from August 10, 2020, BSN will start its global expansion through integration with mainstream public chains. This is not only a major breakthrough in the construction of domestic blockchain infrastructure, but also a solid foundation for China's blockchain technology services to go global.
What can BSN bring?

• High-quality mass service

• Leading the digital transformation of the global economy

• Save blockchain application deployment and operation and maintenance costs

• Lower the threshold for blockchain application development and increase the convenience for users to participate in blockchain applications

• Provide flexible access methods

• With fast networking mechanism

Let us first understand the core architecture of the BSN service network, which mainly focuses on two points: [data effectiveness and security] and [data storage].
Data validity and security

We can see that the BSN architecture has two cores: Is the data valid? And can the data be guaranteed to be safe? The main method of BSN is to manage the validity of data through data control and allocation management; the security of data is to ensure the security of data through data control, encryption management, data encryption and other forms of smart contracts.

Storage security

As can be seen from the above figure, BSN is currently mainly based on the alliance chain and public chain framework. At present, whether it is the core system of BSN or the Internet, application services, etc., the market is mainly based on centralized storage, and some encryption measures are combined to ensure the security of data storage and transactions, which may not be so perfect to a certain extent. Regarding data validity and security, data storage, then Filecoin itself can achieve it very well.
Encourage effective data

The verification database mechanism encourages miners to store and access valid data. The main purpose is to prevent miners from gaining benefits through invalid data attacks and consuming the storage capacity of the entire network. The data stored by the customer becomes valid data after being verified by the Filecoin network. Both miners and customers are motivated to verify the data. Miners can obtain higher block rewards by storing verified valid data, and customers will also increase the priority of miners in processing their own transactions by providing verified data.
Secure storage of data

The Filecoin network is not easy to attack, mainly because file encryption is dispersed across multiple nodes, making data difficult to match, thus preventing DDoS attacks; asymmetric elliptic encryption ensures that data can be unlocked in one direction.
In addition, Filecoin's download speed is faster than centralized storage and the cost is relatively cheap.

• Using the traditional method, you need to download the completed content from a centralized server each time; Filecoin downloads related content from multiple nodes at the same time, which is similar to P2P downloads (Thunder, BitTorrent).

• Traditional equipment is expensive, which results in high user consumption costs. Google's data storage service costs $5/T per month, and Apple's costs $22/T per month. The Filecoin network utilizes idle storage space around the world, so there is no single IDC cost to cover all storage. Sia data storage costs $2/T per month.

Therefore, once Filecoin is launched on the mainnet and commercial applications are available, it will undoubtedly be a great benefit to BSN, because BSN itself is a centralized decentralized architecture, and at the same time advocates more cost-effective and low-threshold services. According to BSN officials, it only takes 20 minutes for users to deploy applications on BSN, and the lowest cost is 2,000 yuan per year.
At the same time, the BSN white paper mentioned storage many times, but did not mention how the storage would be implemented. I believe that after Filecoin is implemented soon, it will become an important "cloud storage" architecture for BSN.
