Summary of report content

The public chain is the most interesting project in the current blockchain field and the most widely used project type at this stage. However, the public chain has certain technical and security risks. Both developers, investors and enterprises need to maintain a calm and cautious attitude towards the public chain. In the past, most of the evaluation of the technical content and R&D of public chain projects came from the interpretation of the content of the white paper and the current project product status. The content of objective data analysis was seriously insufficient, resulting in the lack of serious data support for the analysis results. Therefore, from the digital generation It is particularly important to extract the pure technical value of blockchain projects from the "noisy background" of the currency. Beijing Tiande Technology Co., Ltd., in conjunction with Chain Tower Think Tank Company and related authoritative institutions, used its self-developed Taishan Sandbox-Blockchain Technology Evaluation Database System, combined with a large amount of historical public chain rating experience, to complete this public chain project Technical evaluation and analysis report.

In this issue, the public chain related information corresponding to the digital tokens with high market value (top 200) was collected and sorted. The data collection date is as of October 15, 2018. By calculating and evaluating specific indicators in multiple dimensions such as its white paper, open source community, source code, technical team, and project products, the overall situation of the public chain project is as follows:

There are 157 digital tokens in open source community projects with open main chain or smart contract source code, of which 156 projects are GitHub community projects and 1 project (Ardor) is Bitbucket community project. This evaluation mainly focuses on GitHub community project development technology Evaluation work.

For 156 public chain (smart contract) projects with core main chain technical data and evaluation conditions, it uses a combination of objective data analysis and subjective technical evaluation, and uses the technical evaluation model framework to calculate the evaluation scores of their technologies, for developers Provide its value reference with investors, and the top 20 rankings of the technical evaluation scores of the current project are as follows.

Overall data analysis and technical evaluation results

An overall analysis of the relevant technical data of 156 public chain (smart contract) projects with core main chain technical data and evaluation conditions, and the summary results are as follows.

Statistical analysis of programming languages

The overall distribution of the core programming language of the main chain or smart contract

The core programming language of the main chain or smart contract is mainly concentrated in C++, Go, JavaScript, Solidity, Python and Java occupying 78.571 % of the core programming language of the entire main chain or smart contract . The dedicated smart contract programming language Solidity is not considered. The current main chain project The programming language used basically conforms to the ranking trend of mainstream programming languages, indicating that these programming language features are more in line with the development needs of blockchain projects. Among them, C++ occupies 29.762 %, Go occupies 23.214 %, and the combination of the two programming languages ​​reaches a utilization rate of 52.976 %, becoming the first choice of programming languages ​​for public chain main chain projects.

The distribution of the top 20 main chain core programming languages ​​in technology evaluation

The programming language types selected by the top 20 main chain projects are very scattered, distributed in 9 programming languages, of which C++ and C# occupy an absolute advantage ( 42.105 %), but from the perspective of the widespread application of other programming languages, The diversity of technology choices indicates that other programming languages ​​can also be well suited for the development of public chain main chain projects.

Statistical analysis of open source licenses

Main chain or smart contract open source license distribution

The main chain or smart contract project licenses are mainly concentrated in MIT, indicating that most public chain main chain or smart contract projects choose loose licenses, which are more conducive to the spread and use of source code. In addition, GPL-type licenses ( AGPL- 3.0, LGPL-3.0, GPL-3.0, GPL-2.0 ) accounted for 30.323 %.

Distribution of Top 20 Main Chain Licenses in Technology Evaluation

Many of the top 20 main chain projects in technical evaluations choose open source licenses that are more inclined to GPL type licenses, indicating that some public chain projects with higher technical evaluations pay more attention to their own core in the process of using open source communities to carry out technology research and development. The protection of technical value and the fulfillment of the obligation of its open source code license are more conducive to its copyright protection and value maintenance.

Code submission analysis

The ranking of the top 20 projects in the number of main chain project code submissions in the past year

The development progress of the above public chain main chain projects in the past year is good, and the community continues to be active. The total number of EOS, TRON, Rchain and 0x code submissions has reached more than 6000 times, indicating that these 4 public chains have been over the past year. The project showed strong technological growth.

The ranking of the top 20 projects in the number of main chain project code submissions in the past month

Comparing with the rankings in the past year, it is found that most public chain projects are still active recently, but EOS, TRON, Waves, Ark, Komodo, Bitcoin, and Namecoin have seen their recent activity decline.

Code contributor analysis

Code contributors are the main or even the only source of vitality that supports the technical development of a public chain project. Most of the core developers of the technical team in public chain projects will submit code for the project as code contributors to lead the technical development of the community And the release of public chain products.

The total number of code contributors who tracked the activity trajectory of the main chain and smart contract projects is 3645 , of which the total number of contributors to the main chain project code of the top 20 in the technical evaluation is 988 , accounting for 27.11 % of the total number of tracked contributors . It is found that the main blockchain core contributors are concentrated in a few high-quality public chain projects, and these open source communities have attracted a large number of code contributors through operations.

Top 10 code contributors by code submissions

There are 82 contributors with more than 1,000 code submissions . The top ten contributors are shown in the figure above. Laanwj is the core code contributor of Bitcoin's main chain project because it also contributes code to many other main chain projects. , Its code contribution submission volume reached 38,305 times, and other contributors such as sipa, gavinandresen, and TheBlueMatt are also active in multiple main chain projects as its core code contributors.

Top 10 contributors ranking for submissions in the past month

As the number of public chain projects continues to rise, some early projects are relatively mature, and core contributors often undertake to review the code submitted by other contributors. This has also enabled many new project code contributors to slowly increase the amount of code submissions.

Analysis of the relationship between the project and the contributors

The total number of contributors is 3645. Many of these contributors cross-contribute code to different main chain projects, and this phenomenon is very common in the public chain development community. Quality and technology inheritance.

The statistics of the top 10 contributors with the most cross-projects are as follows
The statistics of the top 20 projects with the most technical relationships in the main chain project are as follows

A total of 494 contributors have submitted code for more than one main chain project. Through the Fork relationship and the intersection of contributors, the technical relationship between public chain projects is formed, which implicitly transfers the personal technical ability of technical contributors between projects. For delivery, there are as many as 70 related main chain projects.
