Core points: The sharing economy is a product of the era of the mobile Internet. In particular, with the further development of the Internet of Things, big data, cloud computing and other technologies, the sharing economy is showing rapid growth. At present, the domestic sharing economy has entered a period of rapid development. In 2018, blockchain technology attracted worldwide attention and blossomed in various fields. What kind of spark will the sharing economy encounter when it meets another high-profile revolutionary technology-blockchain?

Sharing economy in the blockchain era

(I) The cornerstone of the integrated development of blockchain technology and the sharing economy

Blockchain technology has gradually landed in the fields of finance, insurance, and food safety. As a revolutionary technology, it has the characteristics of decentralization, openness and transparency, traceability, security and reliability, and can solve the problem of trust. These characteristics are in line with the concept of the sharing economy.

The cornerstone of the "blockchain + sharing economy" fusion

First, the blockchain's distributed accounting function fits into the P2P network.

The sharing economy is similar to the P2P network economy. Individuals and individuals can interact and confirm in real time. The supply and demand sides can communicate in real time, reducing many intermediate links, improving transaction efficiency, reducing transaction costs, and changing traditional transaction and employment models . People can easily obtain more diversified employment opportunities and a wider range of revenue channels through knowledge and skills or asset sharing platforms, so that the value of individuals can be fully exerted, and the value of assets and their own values ​​can be maximized.

One of the core functions of blockchain technology is distributed accounting. It can record every node participating in the data transaction and store all data information, and ensure the completeness of the data through P2P network communication technology, decentralized security protocol, encryption technology, etc. Each information interaction in the blockchain system can be broadcast by a single node to all nodes in the entire network, and can verify the results recorded by other nodes, thereby ensuring the security and correctness of the information.

Utilizing the distributed accounting and decentralization functions of the blockchain technology, the sharing platform does not need to establish a trust relationship between different individuals through traditional centralized institutions, and there is no need to perform trust-related verification between different individuals. Low-cost, efficient transactions. This approach can change the participation rules and operating models of traditional sharing platforms, thereby providing great possibilities for the business model innovation of the sharing economy.

Second, the consensus mechanism of the blockchain can reshape the form of asset and value sharing, and reshape the new form of asset circulation, collaboration and value delivery based on consensus.

Blockchain technology can provide a unique proof mechanism. Through consensus mechanisms such as proof of work POW, proof of equity POS, proof of share authorization DPOS, Byzantine fault-tolerant PBFT, authorized Byzantine fault-tolerant dBFT, and other nodes to reach consensus. In addition, encryption technologies such as digital signatures and asymmetric keys, which are widely used in blockchains, can protect them during data storage and circulation, so that nodes on the chain can exchange data under the premise of ensuring data security, thereby ensuring In addition to the reliability of ownership and transactions of assets (both tangible and intangible assets), it can also provide credit protection for the system.

Third, the effective circulation of shared assets cannot be separated from the token incentive.

The premise of everyone sharing and everyone participating in the sharing model is that the assets are real and reliable, everyone is credible, and everyone can be motivated. The blockchain's consensus mechanism and encryption technology ensure the authenticity and reliability of the assets. The blockchain's distributed ledger and decentralized protocols make peer-to-peer sharing and transactions credible.

Driven by the blockchain-based token (or points) system, members of the shared ecosystem are more willing to participate in the issuance, circulation, and trading of tokens on the platform; the blockchain token system is easy to use, flexible and efficient at the technical level. The advantages of speed, compliance and safety can achieve the effect that everyone can motivate. On the market side, the blockchain token has the ability to solve the financing of a certain asset (such as real estate, intellectual property, high-tech products, etc.), open up the upstream and downstream ecological chains, bind stakeholders, and solve trust between people. Problems, and provide more kinetic energy for the initial operation of the platform. On this basis, the sharing platform can also use the distributed data system of the blockchain to promote ecological integration and data sharing, thereby improving resource utilization and high-speed circulation of funds.

In the token system, all objects in the sharing ecosystem, including platform parties, asset providers, users, regulatory authorities, etc. can join. Resource interoperability and data sharing within the ecosystem, especially the participation of regulatory authorities can promote the sharing economy. Compliance and healthy development. In addition, the token incentive can also achieve the value chain interoperability, improve resource utilization, promote ecological integration and other effects, and achieve effective interaction and circulation of resources.

Fourth, blockchain smart contracts provide program support for the sharing economy.

Smart contracts are a set of commitments defined in the form of digital algorithms. Contract participants can automatically perform commitments in specific network environments, that is, under conditions that are met, commitments can be automatically implemented in network information platforms and systems. ,fair and just. Smart contracts decentralize the entire market, and do not require the participation of a specific central coordinator to enable automatic trust between the parties and execute automatically according to a specific workflow. In the design of the blockchain sharing model, it is feasible to use blockchain technology to achieve decentralized transactions and transfer of any form of digital assets.

The smart contract system based on blockchain technology has both the advantages of automatic execution and trustworthiness, which helps in the sharing economy, such as product / service reservation, product delivery, and default payment, and other business scenarios involving online trust. Plastic and business upgrades make shared products / services more secure, reliable, and efficient circulation. This is equivalent to providing technical support for the standardized operation of the platform. With the continuous improvement of the level of blockchain technology, smart contracts are expected to become the infrastructure for a standardized solution of the sharing economy in specific application scenarios in the future.

In the future, blockchain smart contracts will play the role of transaction executors in the sharing economy, greatly reducing the cost of value exchange with low-cost, automated transaction methods. In the process of specific applications, combined with the Internet of Things facilities to further solve the physical problem Pain points and difficulties of sharing. For example, one of the reasons why the current sharing economy fails to land on a large scale is that the cost of value transactions is high. When the value of value transaction costs is greatly reduced, everything can be shared in a reliable and reliable manner anytime, anywhere, supplemented by appropriate terminals. Realize the landing of value sharing.

To sum up, in the blockchain system, the basics of "blockchain + sharing economy" are as follows:

First, trust and consensus among system roles are established based on technologies such as digital encryption and distributed node signatures. Second, business with rules attributes such as transaction use of assets, default compensation, and expiry accounting can be carried out fairly and automatically with the help of smart contracts. The user's non-compliance will be dealt with accordingly, and the user's behavior that is beneficial to ecological construction will be rewarded. It is under the support of smart contracts that users on the chain can directly interact and achieve platform autonomy according to established ecological rules; in addition, on the basis of solving trust issues, relying on the e-commerce system of the shared platform and the token The design of incentives can effectively promote the transaction flow of shared assets between multiple chains, and realize a programmable business ecology of the sharing economy.

Sharing economy foundation based on blockchain system

The combination of the sharing economy and blockchain makes P2P rental sharing platforms the main beneficiaries, such as Airbnb, HomeAway, GSENetwork, FlipKey, and OneFineStay. Such platforms have similar characteristics, such as users temporarily giving away idle socialized resources to others for sharing, a large base of supply and demand, integration of supply and demand, and the main body of supply and demand is an individual or a small economic organization. The main role of this type of platform is to integrate and share idle social resources, so that both supply and demand can directly interface with each other to achieve an optimal match between supply and demand, thereby achieving efficient resource flows.

In the application process of "blockchain + sharing economy", the Internet, the Internet of Things, and big data are the most important carriers. The role of the Internet + Internet of Things is to connect physical or non-physical idle resources, and make the supply and demand of the sharing economy respond quickly with instant interaction.

The sharing economy is a new economic model that conforms to the concepts of "innovation, green, openness, and sharing." With the advent of the Internet era and constant breakthroughs in information technology, the "shared economy" can continue to deepen its business, economic, and social models; and with the blessing of blockchain technology, its potential will be further released.

(II) Ecological Model of "Blockchain + Sharing Economy"

The Internet has established a connection foundation for the sharing economy, and realized asset-based supply and demand connections through social networks and payment tools. However, in information sharing platforms in the current Internet environment, data centralization is more serious, which easily leads to information / data distortion and data loss. , Data tampering, etc., resulting in unreliable platform assets and low transaction efficiency.

The future decentralized business model should take ecological construction as the core, and collaboratively create and share value with the participation of multiple roles, flexibly respond to market responses, and continue to evolve. Blockchain technology is a new type of architecture technology. Its birth, development, and application fit well with the development of distributed business models, including the sharing economy and collaborative economy.

The decentralized peer-to-peer sharing economy is an important model for improving economic operation efficiency and economic and social benefits, achieving a balance between supply and demand, and reducing excess capacity. Based on the perfect combination of its own technical characteristics and sharing mode, the blockchain will reshape the face of the sharing economy. In the "blockchain + sharing economy" economic paradigm, individuals are both suppliers of resources / values ​​and consumers of resources / values. Each organization or individual participating is the core of the shared ecological construction, and each participating Everyone can realize their own value from the blockchain sharing system, and obtain benefits at the same time.

Aiming at the characteristics of the sharing economy business, based on the platform-based sharing model and the use of blockchain technology characteristics, a decentralized ecological service system is created. Its core includes six major systems: the intelligent IoT data service system, and the asset on-chain confirmation system , Credit system, smart contract system, incentive system, business collaboration system, etc.

"Blockchain + Sharing Economy" Ecological Model

Among them, the intelligent IoT data service system and asset on-chain right confirmation system are ecological resource supply systems that inject energy into the ecology; business collaboration systems are ecological resource consumption systems that support the effective matching of resource supply and demand through business collaboration to achieve collaborative consumption . In the sharing economy, collaborative consumption is considered to be the basis for the development of the sharing economy. It enables users' personalized consumption needs to form an agglomeration effect through a sharing platform and promote the effective transfer and circulation of resources. The credit system and incentive system are ecologically "Inorganic" resources, a potential prerequisite for the stable operation of the sharing economy is the establishment of credit and incentive mechanisms. Trust and incentives make the cost-benefit of multiple actors in the ecosystem sustainable, which is the key to improving the efficiency of supply and demand matching.

The credit system is the internal drive system of the shared platform. First of all, in a blockchain P2P network, nodes can establish a trusted connection without the need for a third party to act as an information transmitter. The self-confidence framework established with blockchain technology can provide brand-new technical support for the sharing economy, effectively Solve the trust problem based on the centralized platform in the industry; Secondly, blockchain technology can establish a smart contract for both parties in the sharing economy transaction, thereby avoiding unnecessary economic losses caused by the breach of the contract by any of the two parties in the transaction, forming various roles The new pattern of business ecology co-constructed and shared between them is conducive to ensuring the normal operation of the sharing economy, bringing new opportunities for development and potential for economic development.

In real transactions, consumer doubts about product quality may affect transaction efficiency. However, there is no such problem in the "blockchain + sharing economy" ecosystem, because the intelligent IoT data service system and asset on-chain confirmation system ensure the quality of the assets in the system and the uniqueness of the assets. The joint verification of the nodes guarantees the quality of the shared platform resources, avoids the problem of repeated transactions to a certain extent, realizes the digitization of assets, and ensures the real-time collaboration between real assets and digital assets.

In the "blockchain + sharing economy" ecological model, resources and people are more accurately matched. Organizational collaboration based on shared resources and the blockchain, as well as data collaboration and intelligent matching of the information platform, have achieved material The full circulation of resources has also achieved the full cooperation between individuals; coupled with the role of economic incentives, organizational cooperation and resource intercommunication have been more effectively linked.

The spirit of the blockchain is "co-construction, co-creation, sharing, and win-win". Resource interconnection and organizational collaboration are the basis for co-construction and co-creation. Goods and assets are only valuable if they have liquidity. The stronger the liquidity, the more valuable it is. high. Tokens are the value vouchers for transactions and collaborations, and are the incentive media for large-scale group collaborations. Digitizing physical assets, confirming digital assets, and tokenizing confirmatory assets can improve the liquidity of assets to a certain extent. Tokens are related to the creation, transformation, use, and processing of value, and are related to human economic activities such as production, saving, exchange, and distribution. The integration of the token incentive system in each activity will make each activity more dynamic. . This is essentially a digital value-driven economy.

In the specific process of token incentive implementation, the issue of incentives can be resolved fairly and reasonably based on smart contracts. Regardless of the provider of resources, data, the demander, or the servicer, if they can provide added value to the ecology, they can get corresponding rewards. The token reward conditions are written into the smart contract system in advance according to the plan, and can be automatically executed if the preset requirements are met, which will be conducive to the continuous improvement of ecological value. For example, bicycle sharing. After the provider uploads bicycle asset information and then deposits the corresponding pledge token, the bicycle can become a smart shared asset. Consumers need to pay for using the asset. After the consumer confirms that the asset is real, valid and safe to use, the pledged token will be returned to the provider's account.

After the two major issues of trust and economic incentives are resolved, the collaboration efficiency and business collaboration efficiency will be greatly improved, which will further promote the circulation and trading of idle assets.

The business model of the sharing economy under the blockchain revolution will present a unique look.

First of all, in the distributed business model of the blockchain, in terms of asset circulation, the possession, use, income, and disposal of assets can be separated from each other, and ownership, management rights, and decision-making rights can also be in the hands of multiple stakeholders. Each stakeholder can be a "node", and the operation of the distributed business model is jointly maintained by a large number of "nodes". Any "node" is independent. Tens of millions of "nodes" are directly docked, and there is sufficient connection and interaction between "nodes", which helps to improve the efficiency of asset transactions.

The specific equity attributes of assets can be defined by one or more tokens in the ecology. The token includes the attributes of asset rights, the scope and boundaries of asset circulation, the anchoring of the value of the asset, and the conditions and methods of asset use, income, and disposal.

Second, the sharing economy is easier to integrate with the financial industry. Blockchain technology provides a trusted business environment for shared platforms, and the development of financial services generally requires multiple parties to participate in the value exchange, but it is difficult to find a common and trusted third party, the information flow and funds provided by the blockchain The closed loop of the flow effectively solves this problem.

For example, Airbnb docks with landlords and renters who have idle houses or beds, and allows suppliers and suppliers to directly trade. The platform mainly plays a role in matching transactions. These business models are decentralized, and the platform faces direct interactions between individuals and individuals, information and information. Blockchain guarantees the credibility of platform information. Based on the credible information and its own trust mechanism, the platform can provide users with financial services, such as prepayment of housing loans.

In summary, the asset on-chain confirmation mechanism, credit constraint mechanism, economic incentives, and business collaboration based on the blockchain system provided by blockchain technology can create an open, innovative, secure, and orderly environment for the development of the sharing economy. Better release the great value of the credit economy.

The main points of building a sharing economy in the blockchain era

(1) Confirmation of assets on-chain

The core of the "blockchain + sharing economy" is to use the distributed ledger, consensus mechanism, token system, and smart contracts of the original market to clear the original idle, unused, non-standard idle resources Centralization, using blockchain technology to trade any form of digital assets, thereby achieving efficient circulation of assets. Therefore, the confirmation of the asset's on-chain right is the basis.

The core of asset on-chain is: asset definition, right confirmation, and circulation transfer.

Asset on-chain confirmation

Asset definition: In order to measure and determine sharable resources and complete asset registration based on blockchain technology, all assets with use value or storage value can be defined and registered. In the specific definition process, the tangible physical resource or intangible virtual resource can be coded through a certain standard format, and the code can be accurately matched, one code and one thing, and uploaded to the chain to ensure the uniqueness of the asset. Of course, the definition of assets can also be implemented using the distributed storage project IPFS, that is, storing the hash value of the file content, addressing based on the file content, and using the Filecoin protocol as an incentive.

Confirmation of rights: The blockchain itself has the characteristics that cannot be tampered with. After the asset is recorded in the blockchain system and signed and authenticated, it is unique, and then the forgery can be prevented by storing the hash value on the chain. If necessary, in the signature system, the ownership of the asset can be clarified by the signature of the regulatory agency and the issuer of the asset, or a special digital certificate can be authorized to the issuer to prove the authority of the asset. Then transfer of ownership and permissions is defined through asset licensing agreements. The confirmation of the asset's blockchain is the basis for on-chain asset equity and securitization. Of course, at the specific operational level, it is also necessary to ensure the corresponding relationship between on-chain assets and off-chain assets.

Circulation transfer: The use value of an asset determines its liquidity performance. Common bearer assets, such as coupons, digital currencies, stocks, financial securities, etc., can be issued based on blockchain networks such as Ethereum. As long as the user has the key, he / she has the ownership of the asset, and can also implement asset communication and traffic sharing between different blockchains based on cross-chain technology. Assets with clear ownership and good liquidity, such as real estate, automobiles, bicycles, households or corporate fixed assets, can be used to transfer and flow supply and demand based on the value exchange agreement of the sharing platform.

The blockchain platform can use smart contracts to manage assets. Once the required conditions are met, the smart contract will be automatically executed. The platform's asset transfer agreement is only valid for the assets being verified, that is, the assets on the platform can be traded only after being verified. The life of the shared asset, the payment of the deposit, the amount of use, and the deductible are recorded in the smart contract. When the smart contract obtains external data and detects that it meets the preset conditions, it will automatically respond on behalf of the enterprise and the user, such as Automatically perform receipt, automatic refund, and automatic collection of assets on the chain. This will greatly improve the liquidity of assets, improve the efficiency of the shared platform, and bring greater social benefits.

(2) Establishing a complete trust system for the blockchain platform

The sharing economy basically takes place in a complex environment involving multiple parties. Because the supply and demand sides do not know each other, they rely heavily on a trust system and a consensus mechanism. That is to say, the sharing platform must have a strong credit mechanism, so the participants' credit construction and behavior data recording and certification have become very important factors.

For example, the use of shared bicycles needs to refer to personal credit to ensure that vehicles are not lost and damaged; shared economic models such as shared houses or shared apartments rely significantly on participants' credit status. The "blockchain + sharing economy" development model can eliminate the disadvantages of traditional credit collection and improve the credibility of credit information.

Data credit under the blockchain system

The blockchain itself is a distributed database. All data and information recorded on the chain are certifiable and open. This provides credit protection for the sharing economy. The blockchain's distributed data structure and multi-node synchronous verification and other technical features enable trusted data to be synchronized to various data demanders, enabling effective data circulation under authorization. Any behavior based on the platform will be recorded on the blockchain, and any node can query information on the blockchain platform, and no third party can modify or revoke the information recorded on the blockchain. .

The data on-chain will make all users of the platform become the supervisors of the platform resources. Multi-node joint verification and openness and transparency ensure the qualification of shared platform resources, which will also solve the problem of trust between the two parties in the transaction and fully increase the platform's information credibility. And the credibility of the platform itself to facilitate public monitoring and auditing. This technical advantage makes blockchain technology widely and deeply applicable in the fields of finance, elections, insurance, intellectual property, charity, and other fields. Specific to the sharing economy, it can provide guarantee for the credit system with user experience as the core.

Credit construction in the blockchain system

In addition to the technical characteristics of the blockchain itself, which can provide credit protection for the sharing economy, in the specific practical significance process, we can also strengthen the construction of the sharing economy credit system through a series of mechanism measures, such as the blacklist mechanism (for participation The untrustworthy behavior of a person can be disclosed on the entire chain), the credit mechanism (for credit-reduction measures, different credit values ​​have different permissions), the arbitration mechanism (for objectionable data or rewards and punishments, users can contact the platform Initiate arbitration, open democratic rulings), third-party credit (the platform can obtain the user's credit report from the third-party credit system), etc.

The credit system based on the blockchain platform can promote the rapid development of the sharing economy and promote the sharing model to serve the real economy more effectively.

(3) "Blockchain + Internet of Things" promotes the development of the sharing economy

The Internet of Things and blockchain seem to be a perfect match, and the combination of the two will open another door to the sharing economy. The blockchain is a distributed database. The Internet of Things can obtain node data by providing a data infrastructure for the blockchain. The blockchain can determine the rights of these data, which solves the serious problem of data centerization of the Internet of Things and the difficulty of privacy protection. , The difficulty of data coordination of the Internet of Things.

"Blockchain + Internet of Things" makes the data generated by the Internet of Things more authentic and reliable, and also makes the decentralization of the blockchain more thorough. In the distributed blockchain IoT, IoT nodes will not be attacked by traditional DDOS (Distributed Denial of Service), data is safe and reliable, devices are connected to each other, node trust issues are resolved, and between intelligent IoT terminals Collaboration is also easier due to the empowerment of blockchain technology. For example, SMARTHOME uses blockchain technology, combining blockchain technology with the Internet of Things technology, not only to achieve the convenience and speed of the Internet of Things, but also to use the blockchain technology to ensure the security of the property of landlords and tenants.

The sharing economy allows users to obtain products and services by integrating idle goods or service resources. Intelligent IoT terminal equipment enables idle assets to open channels for (physical) asset sharing, such as bicycle sharing, car sharing, and real estate as we know it. Or the sharing of work areas and energy sharing through charging stations are inseparable from smart IoT terminals.

With the Internet and blockchain technology, IoT terminal devices will no longer be isolated, and resources can be exchanged between terminals. Relying on decentralized blockchain technology, idle resources and data will be shared. To the extent that the value of the resource itself is realized, decentralized sharing and collaboration of the value of the asset is achieved. Each participant can conduct efficient transactions point-to-point according to their needs, and everyone becomes a producer and consumer at the same time. At the same time, blockchain technology will also enable IoT devices to process payments independently, and embed smart contracts in the transaction process to ensure the credibility of transactions. For example, Smartshare and OpenBazaar are exploring the construction of a universal blockchain sharing platform that fully integrates the blockchain and the Internet of Things to achieve true point-to-point sharing with the advantages of low cost, fast transactions, and strong credibility.

When the blockchain and IoT technologies mature gradually, the degree of integration between the two will be higher. If all smart IoT electronic devices are connected to the blockchain security chip, the connection between the Internet of Things and the blockchain and assets will be more fully realized, thereby promoting the integration of physical assets and the blockchain and the effective matching of supply resources. Boost the rapid development of the sharing economy.

 

Development Summary and Suggestions of "Blockchain + Sharing Economy"

to sum up:

The sharing economy is an important product of the era of the Internet economy. With the in-depth development of the sharing economy, a series of problems such as asset quality, lack of trust, privacy protection, and security supervision have also emerged. The emergence of blockchain technology has made the process of asset confirmation, transfer and transaction open and traceable, which has guaranteed the qualification and credibility of shared assets to a certain extent. At the same time, the construction of smart contracts and trust systems based on blockchain has significantly improved the efficiency of asset transactions, and further stimulated the circulation and utilization of assets.

The integration of blockchain technology and the sharing economy provides new methods and ideas for the development of the sharing economy, promotes the upgrading of the sharing model, and promotes the rapid development of the sharing economy. Against the background of the stagnation in the development of the sharing economy supported by the Internet of Things, big data and other technologies, an inevitable choice is to integrate blockchain technology into the sharing economy including finance, medical care, energy, etc., to optimize the sharing model and transform Sharing and upgrading the platform brings new potential to the development of the sharing economy.

Suggest:

1. Focus on subdivided fields and use new technologies to create new growth

At this stage, the sharing economy is mainly concentrated in the fields of tourism, hotels, transportation, retail, video, and audio communication. With its own development, the sharing economy has spawned more subdivided fields, such as parking space sharing, office sharing, charging treasure sharing, charging pile sharing, fitness sharing, WiFi sharing, and book sharing.

Each segmented sharing area has the opportunity to use the Internet of Things, big data, blockchain and other technologies to reshape existing sharing models and forms, solve problems such as trust, asset security, and business collaboration, and shape a shared A new sharing model with participation and incentives for everyone, thereby maximizing the benefits of the sharing economy.

For example, the media field can use blockchain to shape the value forms of national participation, co-creation of content, common communication, and in-depth interaction. Through the multi-channel interactive experience, each member can share and forward comments, and promote deeper communication and interaction between members through the reward mechanism.

2.Strengthen the platform's deep operation and platform autonomous system construction

Many shared platforms are places where multiple parties are connected to supply and demand, and provide virtual or real transactions; the more participants on the platform, the greater their value. However, in the early stages of the operation of the platform, there are basically difficulties in starting, accurate user acquisition, and supply and demand matching. And other issues. When the token incentive system is added to the platform, the platform's initial deep operation will gain more opportunities.

As the number of participants gradually increases, a small number of participants will do evil in the open platform from time to time. This requires strengthening the platform's autonomous system construction. On the one hand, strict rules and regulations are set to restrict potential evil acts; on the other hand, the transparency, standardization, and authenticity of the platform can be improved through technical means such as blockchain to reduce Platform autonomy risk.

3. Focus on the integration of blockchain technology with other technologies

First of all, the current issues of consensus efficiency, distributed high storage, data security, and transaction capacity per block of governance on the blockchain constitute a certain obstacle to the large-scale application of blockchain technology in the sharing economy. In order for blockchain technology to fully integrate into the sharing economy, we still need to increase technical research and development and resolve technical bottlenecks.

Secondly, the technological integration of "Internet of Things + Big Data + Blockchain" is the key to building a new model of the sharing economy. In terms of "Blockchain + Internet of Things", we can focus on the instant integration of IoT data systems and blockchain systems, and develop program interfaces for Internet of Things and blockchain technologies; In terms of "data", we can use the open and transparent characteristics of blockchain technology data to reasonably test the authenticity of data on the shared platform, improve the credibility of information, and eliminate hidden dangers to information security.

4.Intensify policy support and industry supervision

Promoting the development of "blockchain + sharing economy" can not be separated from policy support and industry supervision. First of all, the regulatory agencies and arbitration methods in the blockchain industry have not yet been defined. In the specific implementation process, unified reference and standard basis need to be further completed to promote the integration of the sharing industry and blockchain technology. Second, the sustained, rapid, and healthy development of the sharing economy also requires policy assistance. Government departments should provide funding and technical support to pioneering enterprises in the sharing economy, and provide sufficient financial support for related technological innovation research.

5. Promote the model practice of "blockchain + sharing economy"

At the enterprise level, enterprises are the main body in implementing new technologies and new model practices, and they need to work hard to promote the "blockchain + sharing economy" model practice. On the one hand, with the support of the government and related policies, strengthen the introduction and cultivation of relevant talents, and introduce high-skilled talents required for industry development; on the other hand, enterprises should continue to improve their own information construction level and actively introduce blockchain Technology, continuously accumulate practical operation experience, and provide a multi-directional reference for the development of the industry.
