The Bitcoin white paper, revealing the blockchain technology, came into life in the year of worldwide financial crisis, 2008.

This nascent technology model featuring peer-to-peer, traceability, trustlessness, decentralization and data transparency, has penetrated into every walk of life instancing government, finance, and public welfare over the past ten years.

Revolutionary changes can only be brought to us by combining blockchain with traditional industry and real economy. In short, blockchainlessness yet penetrating. As a new system, blockchain does not have the ability to interact with external data itself, yet fortunately enough, such weakness should be perfectly complemented by oracle, thus realizing the full function of smart contracts.

What is oracle in the realm of blockchain？

In a most comprehensible way, oracle connects blockchain to the real world.

If smart contract should be seen as a protocol established beforehand, where codes automatically take effect when the external information reaches the conditions triggered. The function of the oracle, differentiating itself from its peer, uploads the data&information from off the chain in the real world onto the blockchain, and completes data synchronization allowing the determined smart contract to respond to the uncertainties. Boom, everything can be connected! What makes oracle in the blockchain more desired is its traits - non-tampering, service stable and auditable, all to ensure the continuous operation of systems together with unique incentivization scheme.

Kendall's Coefficient Chain: a new decentralized oracle system

Kendall's Coefficient Chain is supported by Kendall Foundation in the North America, where there is a dozen of specialists from blockchain institutes in Stanford and MIT. Research and development experience in NEST and LINK, along with over 7 seven’s devotion to traditional sector blockchainizing, enables KCCK to become the very forth generation blockchain with the feature of DeFi and blockchainization.

If the first generation oracle is represented by Provable and Town Crier, the second alliance oracle by the MakerDao, the third indirect oracle by ChainLink, then the fourth should be Kendall's Coefficient chain.

By combining the advantages of the first three generations, Kendall's Coefficient chain (KCCK) aims to provide continuous, efficient and credible data information for blockchain systems, not only in the field of DeFi, but also in the fields of financial derivatives trading platform, borrowing&lending platform, express tracking/IoT, stable currency, games, insurance, forecasting market and so on.

Kendall's Coefficient Chain: Provide efficient, correct and credible data

The Kendall's Coefficient Chain applies Kendall’s coefficient of concordance as core of its contract. Kendall’s coefficient of concordance is a measure of agreement among raters defined as follows:

Kendall’s W statistic (sometimes called the Coefficient of Concordance) is a non parametric statistic to calculate the correlation degree of multiple grade variables in mathematics. It’s used to assess agreement between different raters, and ranges from 0 to 1. Zero is no agreement at all between raters, while 1 is perfect agreement. The statistic is calculated either on an interval scale or on an ordinal scale.

（Kendall’s W Formula）

The Kendall's Coefficient Chain is naturally applicable to the field of oracles. By comprehensively weighting the data of multiple rating objects and incorporating them into the oracle system, the credibility and objectiveness of the data are ensured. At the same time, the Kendall's Coefficient Chain token KCCK will be used for incentives to form a comprehensive and healthy ecology.

In addition to multi-parties weighted consensus, the Kendall's Coefficient Chain focuses on the combination of on-chain contracts and off-chain information. The design model makes the handling fee cheaper and faster. By applying cross-chain technology and Layer-2 technology, Kendall's Coefficient Chain public chain provides credible data to improve the efficiency of Dapps and public chain systems.

Based on the "price facts", the Kendall's Coefficient Chain generates the price facts of the off-chain market simultaneously on the chain through miners' bilateral asset quotation. By combining with the Kendall quotation mechanism for mining, and rewarding the "price-feeding" miners, Kendall generates a logical closed-loop, credible and efficient distributed quotation system.

Kendall's Coefficient Chain（KCCK）：Born to Win in the Trillion Market

Until September 2020, the global DeFi lock-up amount has reached a maximum of 9.5 billion US dollars, in which the oracle system plays a very important role, and the oracle market cap has also risen.

As a former leader in the oracle market, LINK has increased its price by 12904% since its issuance, and its market cap has also ranked fifth among mainstream digital currencies.

LINK has finished its historic mission and the fourth-generation brand new oracle, Kendall's Coefficient Chain comes to the stage of oracle. Kendall's Coefficient Chain adopts a brand-new technical model and absorbs successful experience such as LINK. The Kendall team has much experience in blockchain and the scope of application is more diverse and broad, so the market prospects are sure unlimited.

Kendall's Coefficient Chain（KCCK），enables information to circulate freely, efficiently and credibly on and off-chain.
