DAC (Da Vinci Coin) is a public chain issued based on blockchain combined with artificial intelligence, in order to solve the cross-border problems of the entertainment industry, payment field and credit certification. Da Vinci is an economic network with close contacts at the non-governmental level for the purpose of establishing domestic networks and even exchanges between countries. It includes not only cultural parts, but also cooperation in various other directions. Da Vinci will be the center of these cooperation An important hub that connects people and organizations in all countries and regions of the world. Just like which country you can go to by plane, Da Vinci also wants to open up trade and cultural exchanges through digital channels.

1. Project introduction

Since Da Vinci public chain uses distributed accounting and storage, there is no centralized hardware or management organization. The rights and obligations of any node are equal. The data blocks in the system are owned by the entire system. The nodes of the maintenance function are jointly maintained. The data is stored in a chained block structure with a time stamp, which adds a time dimension to the data and has strong traceability and verifiability.

Use a specific mechanism to ensure that all nodes in the distributed system can participate in the verification process of data blocks, and select characteristic nodes through consensus algorithms to add new blocks to the blockchain. The Da Vinci project uses consensus-based norms and protocols to enable all nodes in the entire system to exchange data freely and safely in a trustless environment, so that the trust in "people" is changed to trust in machines, and any human intervention doesn't work. Once information is verified and added to the blockchain, it is permanently stored and modifications to the database on a single node are invalid. The system is open, except that the private information of the parties to the transaction is encrypted, and the data is open to everyone, so the information of the entire system is highly transparent. Since nodes do not need to trust each other, there is no need to disclose identities between nodes, and each participating node in the system is anonymous.

Project Features

High-performance system advantages:
The internal trading system adopts memory matching technology, which can ensure that there will be no delay and lag in order payment, transaction and settlement processing. Separate into different modules for separate layered management, using distributed cache, the application server needs to access a dedicated cache server to obtain data, and use CDN and reverse proxy to do load balancing for the website and optimize the performance of the database. The number of concurrent supports exceeds 20 million. The system adopts advanced technical architecture, parallel layering is carried out according to the layering mode, and asynchronous processing technology improves the efficiency of concurrent processing of the platform and the integrity of data. Improve system responsiveness through cluster deployment, be able to quickly respond to user requests, and have reliable disaster recovery capabilities. Partial system problems do not affect the normal operation of the overall system, and the upgrade and update can be completed without downtime through the automated deployment management platform.

Fund security:
Adopts an advanced multi-layer, multi-cluster system architecture. The design of multi-layer architecture greatly improves the performance, security, stability and scalability of the system. Function deployment. And through mobile phone and email authentication security, Google double authentication, offline wallet, multi-signature mechanism, high-defense hosts to deal with network traffic, shield DDoS attacks, server SLB balance and simultaneous backup, financial reconciliation platform fund monitoring, etc. to ensure the safety of user funds. worry. Using the network security architecture and risk control system that has been repeatedly verified in traditional finance and used for securities and bank transactions, to maximize the security and stability of user funds.

Application scenario

The Da Vinci project will mainly integrate blockchain technology and token systems in many fields including culture, assets, bonds, credit reporting, insurance, finance, Internet of Things, etc., to optimize and change problems in the above fields , At the same time, in the combination with these industries, the design of appropriate smart contracts will be used to store various information, data, and mechanisms generated in the application in the Da Vinci blockchain. The combined token system can serve as a payment center to further promote the development and integration of this ecosystem, which is conducive to social progress and the convenience of people's daily production and life.

Technical Overview

Davinci Platform(Da Vinci Platform)
Da Vinci Project's platform connects all things that can utilize Da Vinci tokens through its own blockchain called "Dchain". It is a dedicated blockchain that can do 8,000 transactions per second and can be used by 10 million users.

Davinci Market (Da Vinci Market)
In Da Vinci Market, performances, sports, content, shopping, travel and other commodities are combined through API, and suppliers are formed through friendly competition in this market , according to this market principle, DAC can be paid to purchase the required property.

Davinci Fund (Da Vinci Fund)
If you use the "Da Vinci Fund", you can directly invest in cultural content such as movies or music that you want anywhere in the world, so as to obtain the corresponding box office quota. Due to the simple fundraising of many people, more cultural content has been formed, which naturally promotes the expansion of Hallyu.

Davinci Wallet(Da Vinci Wallet)
The Da Vinci Wallet, which can transfer and store Da Vinci tokens, is connected to the Da Vinci network platform. The wallet can be divided into a website version and a mobile version. DAC transactions are available in the DaVinci Network ecosystem. The Da Vinci wallet has a unique wallet address. Through this electronic wallet, DAC tokens can be kept and bought and sold in the Da Vinci chain, and the transaction details can be confirmed immediately.

Davinci Wallet can not only store DAC, but also a multi-functional wallet that can store multiple cryptocurrencies. Through the barter function of Dex tokens, it can be exchanged with other tokens at a ratio of 1:1. Therefore, any cryptocurrency can be exchanged through DAC. As a multi-cryptocurrency wallet, the DAC wallet is combined with all services on the Da Vinci platform. The wallet can store, accept, send and exchange various encrypted digital coins for payment, transaction and settlement, bringing people's lives and transactions Come conveniently.

Davinci Pay(Da Vinci Pay)
This APP is designed to easily use Da Vinci tokens and bring convenient tools to the Da Vinci platform. Of course, even if there is no device that connects the service provider and the buyer in the form of a mobile app, settlement and remittance can be performed through the Davinci Pay platform of the Da Vinci project platform. Davinci Pay is authenticated using a very secure blockchain, so it can be said that credit card settlement is more accurate and safer than cash settlement.

DChain (Da Vinci chain)
In order for the blockchain to be used by the public, it must have the characteristics of flexible use, such as the Dapp of the Da Vinci project platform. To this end, there will be a genesis block technology that can accommodate millions or even tens of millions of users. Dchain's protocol mechanism follows the POS (Proof of Stake) share certification method. The content of this POS protocol is that Da Vinci tokens are owned and kept in the wallet, and after a certain period of time in the staking process, compensation is obtained according to the contribution to transaction processing and block generation.

Two. Comment

Davinci Coin strengthens global transactions by building an efficient, fast and secure simplified settlement system, disintegrates currency boundary rules, and reduces the complexity of financial and accounting verification. In addition, credit information can be managed more transparently. For example, insurance companies can reduce disputes and rationalize compensation claims through the transparency of shared information.

Due to the construction of a decentralized encrypted network, the security has also been strengthened, so the cost is saved, and the remaining resources can be shared. For example, the food we eat and the products we use can be tracked, and the details of real estate transactions can also be will become digital and transparent.
