Blockchain technology and domestic and foreign case sharing directory 01 Blockchain concept introduction 03 Bubi blockchain platform 04 Foreign case introduction 05 Bubi case introduction 02 Blockchain technology introduction 06 Freely explore the essence of blockchain technology and the rise of technology that creates trust. The rise of distributed shared accounting technology. Peer-to-peer value transfer. The rise of blockchain technology. Blockchain: A technology that creates trust and uses a network instead of a centralized organization to achieve accounting. Blockchain, a machine that creates trust, realizes point-to-point transmission of value, and avoids repeated payments. Trust-dependent algorithms Blockchain: the cornerstone of value Internet distributed shared accounting technology Distributed accounting, independent level-by-level accounting in a single center Traditional centralized accounting accounts on the blockchain. The central institution’s ledger enables point-to-point value transmission. Peer-to-peer value transfer requires trust. However, point-to-point value transmission has not yet been realized, and it still relies on central agencies for accounting. Today's Internet almost perfectly solves the problem of transmitting information to anyone, at any time. , positioning, low-cost blockchain basic principles distributed shared accounting key technologies distributed shared ledger owner multi-center data storage multi-center transaction verification multi-center blockchain logical structure key blockchain technologies: dynamic decentralized interconnection zone Blockchain key technology center node: ledger structure cryptography ledger blockchain structure: chain hash structure transaction structure: public and private key system to identify the owner The third key technology of blockchain: consensus mechanism Hash function: irreversible One-way function.

Currently, Dozens of companies have developed core patented technologies and developed a highly scalable, high-performance, and highly controllable blockchain basic service platform. It has the ability to quickly build upper-layer application services to meet the needs of large-scale user scenarios.
Bubi’s vision: Let digital assets flow freely. Bubi's blockchain has been applied in: digital assets, trade finance, equity bonds, supply chain traceability, joint credit reporting, public notarization, data security and other fields, and is developing application cooperation with mainstream financial institutions such as exchanges and banks. With multi-party trust as the core, we are committed to building a new generation of value circulation network to allow digital assets to flow freely. Massive users of the Bubi blockchain support efficient transaction verification and synchronization, support privacy permission policies and rich permission policy configurations for tens of millions or even billions of users, and provide visual privacy protection operations based on application needs from network, system, business, etc. management level. Quickly apply operation management to build multi-mode ledger structures and business models, and quickly build applications. Built-in smart contracts support programmable contract development and provide standardized contract templates. Blockchain-as-a-Service targets various industries and offers configurable enterprise-grade zones.

In new business scenarios, Bubi can quickly customize connections for users based on existing frameworks to meet business functional requirements. It also provides an encapsulated SDK software development kit that supports multiple mainstream development languages (JAVA, C++, node-js, PHP). Bubi Blockchain Adapter Asset Traceability Certificate - jsPHP Platform Advantages - Scalability The blockchain structure of Bubi Blockchain can meet the needs of different business fields and improve the scalability and maintenance efficiency of the system. It can be used to tag assets and asset transfers, and can also provide an immutable, multi-dimensional record of events. It can also be used for traceability and tracking the circulation process of items. Bubi Blockchain Adapter Asset Traceability and Certificate Deposit User A User B Time Action Related Personnel Solution Advantages - The high-parallel publishing platform implements distributed cluster solutions through module decoupling, which can support the implementation of large-volume users and high-concurrency applications. The current distributed architecture of two servers can stably support high concurrency. The online business environment already has 5 million users and 300,000 transactions per week. Advantages of the Bubi Node Platform - Advantages of the Concurrency Platform - All code for the Bubi blockchain deployed on the entire platform can be compiled and run across platforms. All platform-related codes are encapsulated into the basic library, and the business logic is independent of the Bubi platform.
In addition to compilation for PCs and servers, it also supports cross-compilation for ARM and MIPS platforms, which can be deployed on mobile portable systems to prepare for the blockchain Internet of Things. At the same time, Bubi has reached strategic cooperation with well-known domestic cloud platforms to achieve rapid deployment on cloud platforms. Advantages of the Linux VM ARM Mips platform: manageability and operation and maintenance. Foreign success stories: Bitcoin cross-border exchange. Bitcoin is the first blockchain-based application product and has been running stably for more than a year. Of course, the blockchain still needs further improvement and transformation before it can be applied to other scenarios. International settlement, payment, and settlement. International trade.

Bubi blockchain supply chain integration. Multi-party participation, information dispersion, circulation link supply chain integration and repeated review - supply chain integration platform, blockchain supply chain finance platform, corporate financial institutions, insurance channels, warehousing and logistics unified vouchers, corporate credit full records, electronic contract service platform, need to understand blockchain technology End-to-end trust can be achieved and data sharing can be authorized; each piece of registration data forms a unified voucher to ensure unique authenticity and reduce verification costs; multi-center data sharing with different permissions, process visualization, and enhanced contract performance transparency; full data recording to promote collection Building a credit system to reduce risk control costs. Bank contract management system integrated with Bubi blockchain. When users of both parties to a contract register as users of the contract management system, blockchain account blockchain records will be generated: electronic contract information, and records of contract operation changes in commercial transactions, while providing contract content and dynamic change queries.

The blockchain platform also supports the batch import function for existing users to facilitate the rapid connection of historical data. The upper-layer application can call the corresponding interface as needed. Blockchain account creation, power contract account mapping, contract information registration, and the contract information submitted by the contract management system are recorded in the blockchain through the certificate deposit "contract registration" interface to realize blockchainization of contract data and multi-signature mode Confirm the rights to the contract, ensure the uniqueness of the contract, and complete the creation process of contract information. The process is safe and transparent, cannot be tampered with, and is easy to trace. After the third party is authorized, the information of the corresponding contract can be viewed.Contract Information Registration Electricity Contract
