With increasing focus on blockchain and growing number of projects, there is bound to be analysis and comparison of popular projects—EOS vs. ETH, Justin Sun vs. Vitalik Buterin, the discussions are never ending. The fierce competition in the industry is indicative of the rapid and consistent development of the blockchain industry, but only high-quality projects can ensure robust development. Chainlink is a blockchain oracle platform that has become increasingly popular in recent years. Looking at blockchain projects around the world, one can see that Singapore-based SCRY.INFO is also a rising blockchain star focused on data transmission. This report conducts a comparative analysis of SCRY.INFO and Chainlink, to see which of the two is going to grab hold of the opportunity and leap ahead of the other in the blockchain industry.
The term “smart contract” dates back to 1995. It refers to a set of commitments defined in digital form. It is safer than traditional contracts and reduces other transaction costs related to contracts. People in the blockchain industry know that Ethereum (ETH) smart contracts cannot automatically access real-world external data, however, such data is a prerequisite for smart contracts. It is this problem that Chainlink’s team targeted to solve and made an essential breakthrough.
Chainlink is a distributed oracle network, and its team has been working in the field of smart contracts for many years. Chainlink provides external data links for smart contracts, and consists of an on-chain smart contract data integration system and collaboration mechanism. Individual developers or enterprises can provide APIs or data sources, and can directly purchase on-chain smart contracts.
What Chainlink does, is it helps on-chain smart contracts to write selected external data and enables smart contracts to be applied in industries such as financial payment, insurance, etc. However, external data can be quite vast and complicated, and a mechanism is required to provide a clear context for users. Chainlink proposes a decentralized oracle network and verification mechanism, including a reputation system, which claims to be able to verify the accuracy and authenticity of external data connected to smart contracts, to a certain extent. However, this claim is as yet to be completely verified as the solution depends entirely on a certain mechanism. Chainlink is built on Ethereum (ETH), however it is said that Chainlink has commenced official development of its own protocol layer, which may have an adverse effect on developers using the current protocol. One of the biggest hindrance for blockchain application development is cost and security issues, and many vulnerabilities have already been exposed in Ethereum Smart Contracts. Hence, Chainlink has to put in a lot of effort to ensure it resolves security and vulnerability issues.
Most people define the protocol layer as a seven-layer network protocol. As the name implies, there are seven hierarchical structure models. The main function is to help different types of hosts implement data transmission. So, what is the relationship between SCRY.INFO that focuses on the blockchain ecosystem and the blockchain protocol layer? The SCRY.INFO protocol layer is an important product of SCRY.INFO and is a blockchain-based database protocol. It is worth mentioning that the SCRY team has been dedicated on blockchain technology research for many years, and both the team and the technology can stand the test of time.
SCRY.INFO’s protocol layer is a combination of a data verification/exchange platform and an oracle. This means that all Chainlink functions form only a small component of SCRY.INFO. From SCRY’s perspective, I believe that the team should focus on the bottom layer of the blockchain, and constantly support different developers to meet the needs of enterprises. It should develop vertically to create a more professional and stable blockchain ecosystem environment. One of the main functions of its protocol layer is to provide a user-friendly SDK toolkit for non-professional developers to build fast and simple Dapps.
There is a data transaction loops throughout the protocol layer. Developers and enterprises can be both data consumers and data providers. The users’ data demand costs can also be reversed by providing data. For example, a team of developers was building a soccer blockchain application, but it lacked relevant real-time soccer and weather data. After comparing many data platforms, the team finally chose SCRY’s protocol layer. However, due to initial distrust, the team applied for intelligent cluster verification within the protocol layer, and chose to rely on 80% of voters for verification to obtain supplementary knowledge, thus ensuring data authenticity a certain extent. Intelligent cluster verification refers to conducting data verification by relying on the strength of the group, which is somewhat similar to the decentralized feature of blockchain.
Comparison of SCRY.INFO vs. Chainlink
It is often said that nothing is permanent in the world, and so is the case with data. Although SCRY’s protocol layer design is ahead of other existing data verification designs in the market, and is more trustable than direct machine verification, it cannot be completely trusted either. Going forward, better solutions are bound to be developed and proposed. Developers and users can split the SCRY protocol layer into separate APIs such as to retrieve data, send requests, verify data, etc. Even the formation of a single function can be completed quickly, which means that it is able to complete different tasks according to different requirements.
Chainlink is engaged in the same business of blockchain + data, however, it solely relies on external data providers. While SCRY leverages external data sources and has also developed its own data sources, i.e., it combines both external and official data. Data Depot is SCRY’s key data warehouse, and currently contains seven categories of real data sources that are cleaned and updated in real time. It is a backup layer for the protocol layer and delivers vital data required by developers. SCRY.INFO’s business partners have been using the protocol layer code, and at the hackathon held in March this year, they already provided the protocol layer code to the contestants. All the contestants’ works are based on the protocol layer.
In the current stage of market development, early adopters, enthusiasts and industry followers prefer multi-dimensional projects that have different uses. If a project is only used as a middleware for data and smart contracts, it will soon be unable to meet the ever-changing market demand in the current environment, where the blockchain business landscape is constantly changing and growing. In order to truly occupy a position in the market, we must rely on the bottom layer that meets the technical requirements. At the same time, in order to meet the growing need of more and more developers, we must provide simple and easy-to-use protocol layers as tools for developers with different technical backgrounds. It is only in this way that we can promote the development of blockchain applications and realize the project’s goal of benefiting society.
