USC is an encrypted digital currency that is stable, readily convertible and secured by the United States dollar. It has been created and is being used as one of the most advanced and sophisticated payment instruments available. Blockchain is an application for distributed data storage, through point-to-point transmission, a consensus mechanism and an encryption algorithm, that achieves consensus among participants without any third parties involved, enabling reliable transmission of trust and value at extremely low costs.

While cryptocurrency is a media that transmits value in the blockchain, payment serves as the area where blockchain is most likely to produce real value. The price fluctuation of encrypting digital currency is a problem for applying blockchain payment to reality. By referring to the linked exchange rate system in Hong Kong, and legal tender as a reserve, the cryptocurrency is issued on the blockchain in accordance with fixed proportions, while a payment gateway of exchange between legal tender and cryptocurrency is provided for all users, thus ensuring price stability of the cryptocurrency, and reducing price volatility caused by speculation.

Lambda is a fast, safe, and scalable blockchain infrastructure project, which provides decentralized applications (DAPPs) data storage capabilities with unlimited scalability and fulfills services such as multi-chain data co-storage, cross-chain data management, data privacy protection, PDP, and distributed intelligent computing through logic decoupling and independent implementation of Lambda Chain and Lambda DB

We believe that all storage projects follow the core requirement of Provable Data Integrity.Also, it is crucial for data projects to store data in an infeasible storage node and make them trusted and secure, in the academic world, there are mainly two approaches which are Provable Data Possession (PDP) and Proofs of Retrievability (POR) depending on the usage scenarios. Lambda has applied these two approaches in blockchain through academic research and engineering verification, which has eliminated the core obstacles of decentralized storage.

APPLICATION SCENARIOS

Trusted and secure data storage
Data development and sharing is the driving force for the development of the data industry and the oil and power source of the future world. Nowadays, the data is stored in a unilateral private data center, where the model obtained and analyzed by the demand side has been proved to have big drawbacks, lack of transactional transparency and without guaranteed data ownership and control right.Our ultimate idea is to promote data sharing and achieve common benefit by the distinct QoS storage of all types of data that can be validated publicly and validated anonymously through the Lambda that can be notarized and trusted.

Public data access and transaction
At present, many data are owned by all human beings, thereby needing a data infrastructure to enable such shared data access and transaction as medical, education, transportation, energy, agriculture, weather, hydrology, infrastructure, scientific research, public safety data etc.These public data, which are common to all humans, can be distributed, verifiable, stored, analyzed, traded, and used on the Lambda platform.

Access control and protection of personal privacy data
The advent of the era of big data brings about tremendous challenges to the ownership of personal privacy data. Usually, data collectors have unlimited right to interpret and use data. With the implementation of GDPR and other bills, the contradiction between data privacy among individuals, enterprises and governments is becoming more acute. Lambda provides reliable, secure and privacy-protected data storage and access capability by means of differential privacy, data encryption and signing, identity authentication and access control, and encrypted transmission.

DApp and Blockchain
So far, many decentralized application projects face the risk of failing to implement, one of the main causes being the shortage of data storage infrastructures.In fact, the essence of an application, centralized or decentralized, is the implementation of business logic, interface display, and user interaction around data access. Therefore, data infrastructure is the core issue of blockchain and decentralized applications. Currently, blockchain ledgers are not suitable for business data storage, IPFS cannot store formatted program access data.While Lambda project provides infinitely scalable decentralized data collection, storage, and access capabilities through elegant chain library decoupling, isomorphic function subchain design, and publicly verifiable data ownership proofs.

IoT data storage
The IoT data are massive, time-series, and simple structured, whose generation process can ensure the authenticity of the data. The IoT data occupy a large amount of storage space, and the value of individual data is small.It needs a lasting work and substantial storage and computing resources to extract value from the data.Lambda’s digital currency can measure the value of small data, motivating people to share and contribute computing storage resources to obtain token incentives.Lambda provides a system of data collection, data transmission, data storage, data computing and data transaction in the field of IoT.With this system, data collected by sensors such as satellite remote sensing data, hydrological data and atmospheric data can be calculated in different dimensions and sold to anyone and institutions that need it through smart contracts.

Artificial intelligence data
In the field of artificial intelligence, the current consensus is that the role of data is many times larger than that of the model.However, the acquisition of metadata is a difficult and expensive issue.The shortage of data hinders the development of the artificial intelligence industry. At present, because of lack of trust, data abuse and other reasons, individuals are unwilling to contribute data, and business organizations that have need obtain data through unconventional means.Lambda will eventually form an integrated network of huge data storage space, and data owners can sell their data through smart contracts on Lambda’s trading platform.In particular, the value of time-series data lies in the insights after the analysis.Data owners do not need to sell the original data, but only sell the analysis results of the data, and even the insights on the results of the data analysis.

Quinads is an advertisement platform with blockchain based where we can create many contents in a form of video, picture, text, and also allows us to socially interact and rewarded by cryptocurrency. Quinads combines social interaction and cryptocurrency.

Every user can create an interesting content and everyone who reacts to what they read or seen will get a reward. So that it is expected to gain attention and transform into a big community.

INTRODUCTION

What is Quinads? Quinads is an advertisement platform with blockchain based consists with contents of video, picture, and text. Quinads has ERC20 token named Quinads token (QUIN). Quinads wants to be the pioneer of Indonesia’s advertising by utilizing blockchain technology and the development of cryptocurrency which is getting so much better in the world and Indonesia for specific. The advance of this technology has encouraged people to compete in creating the most brilliant idea that beneficial to the whole involvedcommunity within.

How Quinads can benefit the whole involved-community? Every member who join in the Quinads will be given a QUIN as a reward if they are performing the sign of interaction such sharing, commenting, or giving like to the content within Quinads.

Mission and vision
Fountain is a block-chained content ecosystem based on Proof of Contribution. Through a set of clear proof of contribution rules, blockchain technology is used to record the contributions of all participants. After accurate calculation, tokens are awarded to all participants. This will effectively motivate people to participate deeply in a content community application and the entire ecosystem, contributing to their strength.

With the constant growth and development of the ecology, Fountain has a rich content community application, and the author, readers, curators, IP investors, block nodes, application developers and many other roles will be taken from the token. Their income. The ultimate realization of our vision: a win-win, sustainable content ecosystem.

Preface
The core concept of Fountain stems from the problems of traditional Internet content community applications: users of content community applications have made great contributions to the community, but they have not been able to obtain effective contribution credits and rewards.
For example, content community applications such as Twitter (Weibo) and Quora (Zhihu), a large number of users have made the following contributions to the application:

User-contributed original content
Users contribute their own time for reading and vote to the high-quality content.
Users contributed their own comments and commit to community activities
The application has been developed in the process of user contribution. The app has gained billions of dollars or even billions of dollars in market value, but it has nothing to do with most users, which is manifestly unreasonable. I believe we all have the same example of empathy:

You are an author on Quora. During the year, you have created many quality posts, and your post has received a lot of approval. Obviously, you contributed to Quora. One year later, you left Quora for some reason, but you didn’t get any proof of contribution and reward.
Imagine that there is a Quora built on Fountain. In the same situation as above, when you leave Quora, you can get 1 million tokens based on the proof of contribution. In the circulation market, the value of 1 million tokens can be 10,000 dollars.

Which is more reasonable? Which Quora would you choose?

Therefore, we came up with Fountain’s design principles: a relatively fair contribution should support any participant who contributes to the development of the community.
It can be seen that the core of Fountain is how to design an open and transparent proof of contribution rule, which we call it PoC (Proof of Contribution). We will explain in detail in the PoC mechanism section.
