⑴ Where does the data exist? Whether each node must have a large enough storage medium

The blockchain adopts a distributed storage method. The data of the blockchain is composed of Blockchain nodes are used and stored, and multiple nodes are linked through the network to ultimately form a complete blockchain network.

Regarding the size of the node, taking Bitcoin network nodes as an example, there are full nodes, pruning nodes, and SPV lightweight nodes. This classification The method is based on two differences: first, whether this node has downloaded the latest and most complete Bitcoin blockchain; second, whether the node can independently verify Bitcoin transfer transactions, that is, whether it can independently realize the basic functions of a node.

Full nodes download the latest complete blockchain data and are the backbone of the Bitcoin network. There are two main types of people using such nodes, one is independent mining miners, and the other is users who run Bitcoin software (Bitcoin core) using default settings.

The pruning node can also independently complete the confirmation of Bitcoin transfers, but it does not download the entire blockchain to the local.

Lightweight nodes are generally used on mobile computing devices. Due to capacity limitations and high requirements for portability, people usually do not download the blockchain locally. Therefore, the wallet operator will check and confirm the transfer in each user's wallet with the complete blockchain on the Internet through the SPV (Simple Payment Verification) protocol.

In the Ethereum network, there are similar classifications of full nodes, light nodes, and archive nodes, so not every node requires huge storage space and must be selected based on the node function.

⑵ A brief discussion on the accumulation of blockchain storage and traffic technology - the era of real WEB3 is coming

What breakthroughs and advances in storage and traffic technology have modern society made? Let’s briefly summarize it for you.

The current Internet is all about centralized traffic and storage. With the development of the world, the bt network was born. The bt network is a distributed storage and traffic system. But it also has its limitations. First, the bt network can only transfer and share single files. Second, the bt network does not have an incentive mechanism. To put it simply, everyone joins the bt network, but there is no willingness to actively save or distribute files, because this is not beneficial to the participants.

With the exposure of bt network flaws, IPFS was born. That is, the IPFS system developed by the Filecoin project party’s protocol laboratory. IPFS is an upgraded version of the bt network. It is on bt networkBasically, a folder system has been added. In the IPFS system, folders can be transferred and shared directly. Others can also browse related data, files, etc. directly from the folder.

But IPFS, like the bt network, has several problems. First: There is no incentive system. Second: In the early stage of file transmission, because there are very few nodes to store files, the efficiency is very low. For example, if A uploads a file and B needs to retrieve it, it can only retrieve it from A. Therefore, the efficiency is very low. If C wants to retrieve, it can only retrieve from the two nodes A and B. If both A and B are shut down, the files will not be retrieved. This is the problem with IPFS and BitTorrent networks. Their initial transmission efficiency is extremely low. Only when files are retrieved countless times and widely distributed among nodes, the transmission speed will become very fast. So the bt network and IPFS system are both a process from slow to fast. If you retrieve a file that is distributed less among nodes, the retrieval capability is very weak and the transmission speed is also very slow. In order to solve this incentive mechanism problem, Protocol Labs developed the Filecoin supply chain.

Filecoin and IPFS are two concepts. Filecoin actually puts the real-life IPFS onto the blockchain. The characteristic of blockchain is decentralization, and nodes do not trust each other. Data transmitted between nodes must be re-checked. This results in very poor performance of the blockchain. After IPFS was put on the chain, Filecoin was formed. Therefore, Filecoin is also subject to the impact of blockchain performance, resulting in the inability to match valid data and the inability to perform efficient retrieval. Filecoin realizes the storage of data on the blockchain, which is a very significant contribution. Subsequently, SWARM and BZZ appeared, but BZZ has no block incentive mechanism and only has a traffic settlement system, which currently seems to be a failure. However, BZZ has also made certain improvements compared to IPFS and Filecoin: a set of active distribution mechanisms. For example: when I upload a video, the video will be actively distributed by the node. The video will be quickly cached to multiple nodes. Therefore, BZZ has made outstanding contributions in traffic settlement and efficient retrieval. Although it left behind technical contributions, it remained a failed project.

From the current point of view, most of the problems in traffic and storage have been solved in the blockchain field. The second is the issue of blockchain performance. After years of evolution, Layer0, Layer1, and Layer2 have also undergone continuous experiments. In recent years, research in the field of Layer 1 has achieved a lot of results and patents. I believe that breakthroughs in high-performance public chains will appear soon.

Therefore, if you want to build a blockchain network that is truly similar to web3, you should achieve breakthroughs in three aspects: FirstOne: Efficient retrieval. Second: Incentivize storage and traffic separately. The third is that there must be an authorized access system. The authorized access system is similar to when people watch video websites and need to pay to obtain data. In the traditional Internet world, there are many monetization channels. The Internet world of blockchain has just taken shape. Therefore, ecological builders can directly obtain certain benefits. Only in this way can the prosperity of the ecosystem be promoted, and the builders of the ecosystem can continue to contribute more useful applications. Finally, breakthroughs in high-performance public chains are also indispensable. Therefore, with the above four conditions, web3 is getting closer and closer to us.

⑷ Force Insights | Filecoin public chain empowers enterprise-level data storage

Not long ago, under the background of traffic being king, Bilibili, Weibo and other social entertainment media, due to The melon-eaters were so enthusiastic that their computers crashed, causing an uproar on the Internet.

For highly centralized Internet platforms, data is mostly concentrated in the platform's database, and the storage capacity is huge. It is an arduous task to protect the integrity and stability of the data.

Blockchain technology, which is decentralized and continues to develop in the direction of formalization, has further entered the public's field of vision.

However, the discussion on whether to choose a public chain or a private chain for enterprise-level applications seems to have never stopped.

Maybe Filecoin can give the answer.

1. The sudden rise of private chains

As the process of informatization and digitization continues to accelerate, the scale of data information shows a trend of explosive growth.

Global financial and technology giants have successively focused on the development and technology application of the underlying blockchain platform. More efficient, secure and more stable digital development has become an urgent need for enterprises.

Compared with Internet giants such as Google, Amazon, Microsoft, and JD.com that have launched application platforms based on basic blockchain services, institutions such as Ant Financial, JP Morgan, and IBM have successively deployed private chains, using In areas such as internal data management and auditing.

As early as 2018, Amber Baldet, JP Morgan’s blockchain project leader, told the Ethereum Conference in Paris that her self-built platform Quorum plans to connect the public and private blockchain chains. Integrate users' blockchain assets and protect the privacy and security of data and assets.

In May of this year, the former communications giant Nokia also revealed that it would establish a secure, private, and authorized blockchain infrastructure to provide data transactions and analysis functions, using AI and automation mechanisms in real time to cope with rapid growth. amount of data while ensuring safe and reliable access to the data.

The dispute between the public chain and the private chain

As a completely transparent and decentralized infrastructure, the public chain allows everyone to read, send transactions and obtain valid Confirmed public blockchain.

Participants on the public chain can obtain consensus benefits through the digital token incentive mechanism.

The main characteristics of the public chain are open source (OpenSource) and anonymity (Anonymity), which means that the public chain has the characteristics of decentralization, difficulty in tampering, convenience, flexibility and intelligence. It promotes data sharing and reduces complexity. It has natural advantages in business processes, reducing operating costs, and improving data security.

However, the shortcomings of public chains are also prominent during the development process.

Private blockchains, because their writing authority only belongs to a specific organization, have credit subjects, and information can be tampered with.

In theory, it does not meet the core characteristics of decentralized blockchain, but private chains can increase transaction speed, control transaction costs, have scalability to support more transactions, and for institutional data Privacy provides greater protection.

Commodity traceability technology based on private chains has long become a battleground for major companies such as Alibaba, JD.com, and Suning. As early as 2In 2016, Ant Financial applied blockchain technology to support imported food safety traceability and commodity traceability.

In early 2017, Alibaba cooperated with PricewaterhouseCoopers to create a traceable cross-border food supply chain.

However, as increasingly rich Internet services continue to emerge, if all applications are only applicable to a single private chain, then many single institutions will be required to provide different private chain services to meet the needs of data processing and storage.

When blockchain construction and operation and maintenance have matured, the cost is very huge and the operation is very inefficient. The technical requirements for cross-chain collaborative processing of data are very high, and it can no longer meet the social development needs of the digital era.

According to IDC research data, the total amount of global data will reach 175ZB in 2025.

According to the capacity of the data storage infrastructure we currently have established around the world, it is far from enough to store such a huge amount of data. It is conceivable that a solution that can effectively store these huge amounts of data is urgent. .

Three Filecoin empowers enterprise-level data storage

Filecion is currently a blockchain benchmark project with practical application scenarios. Since its launch in October 2020, it has completed up to 8.8 EiB storage accumulation.

As the incentive layer of IPFS, it not only provides rewards for users to share network bandwidth to maintain the smooth operation of IPFS, but also includes the continuous launch of ecological support projects by Protocol Labs and the Filecoin Foundation to promote the sustainable development of the ecosystem. .

Currently, the Filecoin network maintains a daily growth rate of about 50PiB and stores multiple enterprise-level important data files in the circle.

The German Aerospace Center uses IPFS for telemetry data storage. All private files taken from the moon during the US Apollo moon landing program were uploaded and saved using IPFS. The world's second largest Firefox browser has used IPFS for retrieval. Data, the World Wide Web and JD Cloud have applied IPFS to store data, and Google Chrome has supported IPFS plug-ins...

IPFS is designed to connect all computer devices to the same file system, through point-to-point transmission, data block content The establishment of a hash deduplication method greatly improves the efficiency of data transmission, saves 60% of network bandwidth, and greatly reduces storage costs.

Its distributed characteristics and encryption algorithm ensure data security. At the same time, IPFS provides the backtracking function of the historical version of Internet data Git. Zero-knowledge proof also enables IPFS to confirm data without revealing details, allowing Data storage is faster, more secure and more open.

With the development of ecological networkContinuous expansion, with the rapid development of Web3.0 storage, more valuable and real data that needs to be stored can be stored in the IPFS and Filecoin networks.

Conclusion

Almost all license management systems, from the lack of suppliers to the diversity of partners, are affected to varying degrees.

It does not mean that a few companies can agree on rules that are applicable to the public.

Only more competition, more choices and more services can be accepted by people.

Open and public Internet has become our main network technology. With the improvement of certification mechanism and technology, public chain, as the infrastructure of the next generation Internet, will continue to promote the development of the web3.0 era.

The public blockchain storage system built by IPFS and Filecoin also has the characteristics of reducing data storage costs, improving data security, efficient data access, and scalable development.

Not only does it subvert the traditional data storage model, it also solves the problems of enterprise private chains with high costs, low economic benefits, single and closed application scenarios, and centralized data that can be tampered with.

In the future, it is also expected that Filecoin can further improve network scale utilization, and it will become feasible to store enterprise-level data on the public chain.

⑸ What is blockchain expansion

Expansion means that when a certain container or carrier is not enough to support or carry the needs of existing things, we expand the capacity or load of the container. It is a means of increasing the volume of objects to meet the growing demand, thereby alleviating the pressure on current containers or objects.
At the beginning of the birth of Bitcoin, Bitcoin founder Satoshi Nakamoto did not specifically limit the size of blocks. The maximum block size could reach 32MB. At that time, the average block size was 1~2KB.
At that time, there were few Bitcoin users and the transaction volume was not that large, which did not cause block congestion. However, with the linear rise in the price of Bitcoin from 2013 to the present, more and more users have caused congestion on the Bitcoin network. The problem of rising user transaction fees gradually emerged.
Up to now, there is a backlog of hundreds of thousands of transactions on the Bitcoin blockchain at its peak. The average transaction fee of Bitcoin has increased 376 times since September 2010. The processing speed of 7 transactions per second is obviously too high. To meet user needs, the Bitcoin community began to explore how to “expand” Bitcoin.
By modifying the underlying code of Bitcoin, the purpose of improving transaction processing capabilities is achieved.
There are two development and design solutions for Bitcoin expansion itself, namely first-layer and second-layer expansion technologies.
· The first layer of expansion technology is to improve the blockchain itself, making the blockchain itself faster and larger in capacity. OverallIn other words, it means changing the content of the consensus part of the blockchain.
· The purpose of the second-layer expansion technology is to move calculations off-chain, that is, to solve problems through side-chain technology.
Expansion protocol and outcome
Expansion protocol generally requires the support of miners, and can be roughly divided into methods such as modifying the block size, soft fork, hard fork, and segregated witness.
Take Bitcoin as an example:
Bitcoin is now split into the large block Bitcoin Cash (BCH) and Segregated Witness. Segregated Witness is now recognized as Bitcoin in the market, and the big block coin is named Bitcoin Cash. It is foreseeable that in the future development direction, Bitcoin will be dominated by off-chain transactions. Including Lightning Network and side chains. These two new things are currently immature, but many people have high hopes.
Bitcoin will develop a large number of Segregated Witness transactions and make more derivative technologies based on Segregated Witness. It is most likely that technology will drive Bitcoin forward.
Bitcoin Cash will focus on on-chain transactions, focus on developing currency functions, reduce transaction friction as the main method, and profit from a wider range of on-chain users as the main development direction.

⑹ Where is the data in the blockchain stored?

The data in the blockchain all exists in the terminal or in the server. Because we are talking about blockchain, its user terminal can also be a server, and the server can also be a user terminal, so it is all stored on these devices.

⑺ The capacity bottleneck of the blockchain has been questioned, and the ecology has made the technology burst with "wonderful ideas"

Under the current trend of blockchain technology becoming a mainstream application technology, the district The most important capacity bottleneck of the blockchain system is essentially limited by the memory capacity of a single full node, which directly restricts throughput. As for the throughput issue, the Ecological Order uses new technologies to solve the problem of doubtful blockchain capacity.

As long as it is a blockchain technology system, no matter what consensus algorithm mechanism is used, whether it is POW, POS, or delegated proof of equity, it will face the same problem. Assuming that the delay and bandwidth of the physical network are negligible, like EOS based on high-speed links in the information center, the second bottleneck of the system is the limited ledger storage capacity, which is essentially limited by the memory capacity of a single full node. It directly limits how many participant addresses and how many DApp applications the blockchain network can carry.

Most of the current mainstream blockchain technology systems, including Ethereum, Bitcoin blockchain, EOS, etc., have current problems, and they are even more serious.Unfortunately, this problem also has no solution. Multi-level caching information base technology can slightly improve the limitations faced, so that only active users will be limited by storage capacity, and the total user base is limited to the capacity of the hard disk. However, this indicator does not cure the root cause, and it is difficult to fundamentally solve this problem.

As a result, ECOL ecological technology focuses its attention on throughput, and on the basis of solving the shortcoming of throughput, it exposes the capacity problem of the block.

The ECOL Ecosystem understands that consensus algorithms cannot actually help solve performance and capacity bottlenecks, so it attempts to improve the performance of the blockchain system starting from an unconventional consensus algorithm. Based on the foundation of the ECOL ecological order credit system, the credit access principle is adopted, and the system of determining and verifying the single-point broadcast rights of each node is perfectly coordinated by leveraging the certainty and uniqueness of the existing blockchain ledger. The POCM consensus mechanism of the ECOL ecological order circumvents the problems of POW workload proof, which is not environmentally friendly and energy-saving, has computing power monopoly, and centralizes the trend, solves the problem of uneven rights and interests of POS, and solves the operational efficiency shortcomings of DPOS.

In the general "block + chain" architecture, all transactions must be packaged into blocks to take effect. If the capacity storage of the block is small, when the transaction volume is large, the packaging speed of many transactions will slow down, and there is even a risk of failure. If the block capacity storage is large, the blockchain information will expand rapidly, ordinary computers will not be able to run the full node, and the running rights of the full node will be in the hands of a few people, which will be contrary to the results of decentralization. This is also the fundamental contradiction in the Bitcoin expansion debate. The ECOL ecological order does not have the concept of a block, so it solves the inherent paradox dilemma of the traditional block + chain structure.

In short, in the face of capacity bottlenecks, the concept of ingenuity in the design of distributed technology systems is extremely important. This is related to consensus algorithms and cryptography. The ECOL ecological order has done a very good job in this regard.
