Summary of the Report

The public blockchain is the most interesting area in the current blockchain field, and it is also the most widely used project type nowadays. However, there are some certain technical and security risks in the public blockchains. Developers, investors or enterprises, all of them, need to keep a calm and cautious attitude towards the public blockchains. In the past, the evaluation of technical aspect and development content associated with public blockchain projects was mainly according to the white paper and the present situation of the project while with a lack of objective data analysis, which resulted in the deficiency of serious data support for the analysis results. Therefore, it is becoming more and more important to extract the pure technical value in blockchain projects from the noisy background of digital tokens. And now, Beijing Tiande Technologies, cooperated with BlockData Company and other related authorities, using their self-developed Taishan Sandbox—the blockchain technology evaluation database system, and combining with a large number of historical public blockchain rating experience, complete this public blockchain project technical evaluation and analysis report.

This evaluation collects and collates the relevant information of the public blockchain corresponding to the high market value (top 247) digital tokens. Data collection date ended up November 15, 2019. By calculating and evaluating the specific indicators of the white paper, open source community, source code, technical team, project products, and other dimensions, the overall situation of the public blockchain projects is as follows:

There are 163 open source community projects with main blockchain or smart contract source code in digital tokens, 162 of which are GitHub community projects and one project (Ardor) is bitbucket community project. This evaluation mainly focuses on GitHub community projects.

For 162 public blockchain (smart contract) projects with core main-chain technology data and evaluation conditions, the evaluation scores of technology are calculated by combining objective data analysis with subjective technology evaluation, using technology evaluation model framework, providing value reference for developers and investors. The top 20 technical evaluation scores of this project are listed as follows.

Overall data analysis and technical assessment results

The related technical data of 156 public blockchain (smart contract) projects with core main chain technical data and evaluation conditions are analyzed as a whole, and the results are summarized as follows.

Statistical Analysis of Programming Languages

Overall distribution of core programming languages for main chains or smart contracts

The core programming languages of main chain or smart contract mainly concentrate on C++, Go, JavaScript, Solidity, Python and Java, which occupy 80.000% of the core programming languages of the whole main chain or smart contract. Without considering the special smart contract programming language Solidity, the programming languages used in the current main chain project basically conform to the ranking trend of the mainstream programming languages, indicating that these programming language features are more in line with the development needs of blockchain projects. Among them, C++ accounts for 30.000% and Go accounts for 23.125%. The combination of the two programming languages achieves 53.125% usage, and becomes the preferred programming language for the main chain project of the public chain.

Distribution of the Top 20 Main Chain Core Programming Languages in Technology Assessment

The programming languages chosen by the top 20 main chain projects are very dispersed and distributed on nine programming languages. Among them, the distribution of C++ and Go languages is basically consistent with the overall distribution, occupying an absolute advantage (52.632%). However, from the perspective of the wide application of other programming languages, the diversity of technology choices shows that some other programming languages can also be well applied to the development of public blockchain main chain projects.

Statistical Analysis of Open Source Licenses

Distribution of Open Source Licenses in Main Chain or Smart Contracts

The main chain or smart contract project licenses are mainly concentrated in MIT, which indicates that most public blockchain main chain or smart contract projects choose loose licenses, which is more conducive to the dissemination and use of source code. In addition, GPL type licenses (AGPL-3.0、LGPL-3.0、GPL-3.0、GPL-2.0) account for 30.612%, mainly represented by Taifang (LGPL-3.0), which is also caused by the infectivity of GPL licenses. Many projects related to the main chain of the Go language or projects without explicit license descriptions (Other) implicitly choose GPL-related protocols.

Distribution of Main Chain Licenses in Top 20 Technical Assessment

The top 20 main blockchain projects in technology evaluation are more inclined to GPL type licenses, which indicates that some public blockchain projects with higher technology evaluation pay more attention to the protection of their core technology value in the process of using open source community to carry out technology research and development. The fulfillment of their open source code licenses is more conducive to their copyright protection and value maintenance.

Quantity Analysis of Code Submission

Top 20 project rankings of main chain project code submissions in the past year

In the past year, the development progress of the above public blockchain main chain projects is good, and the community is still active. The total number of submissions of EOS, TRON, Rchain and 0x codes has reached more than 6000 times, which shows that the four public blockchain projects have shown strong technical growth in the past year.

Top 20 project rankings of main chain project code submissions in the past month

Compared with the rankings of the past year, most of the public blockchain projects have been continuously active in the near future, but the recent activities of EOS, TRON, Waves, Ark, Komodo, Bitcoin and Namecoin have declined.

Analysis of Code Contributor

Code contributors are the main or even the only source of vitality to support the technological development of a public blockchain project. Most of the core developers of the technical team in the public blockchain project will submit code for the project as code contributors to lead the technological development of the community and the release of public blockchain products.

The total number of code contributors tracing the active trajectory of main chain and smart contract projects is 3353.Among them, the total number of code contributors of the top 20 main chain projects in technical assessment is 1151, accounting for34.33%of the total number of tracked contributors. It can be found that the core contributors of the main blockchain are concentrated in a few high-quality public blockchain projects, and these open source communities attracted a large number of code contributors through their operations.

Code Contributors in The Top 10 Of Code Submissions

There are80 contributors with more than 1000 code submissions. The top ten contributors are shown in the figure above. As the core code contributor of Bitcoin main chain project, laranwj contributes 37947 code submissions due to its contribution to many other main chain projects. Other contributors such as sipa, gavinandresen, TheBlueMatt are also active as a core code contributor in multiple main chain projects.

Top 10 Contributors Ranking of Submissions in The Past Month

With the increasing number of public blockchain projects, some early projects are relatively mature. Core contributors often undertake the audit of code submitted by other contributors. This has also led to a gradual increase in code submission for many new project contributors.

Analysis of the Relationship between Projects and Contributors

The total number of contributors is 3353, many of which cross-contribute codes to different main-chain projects, and this phenomenon has become very common in the public blockchain development community. The research and development of contributors across various projects has also resulted in homogeneity and technological inheritance of some of the projects.

Statistics of the Top 10 Contributors Spanning the Largest Number of Projects
The statistics of the top 20 main chain projects with the most technical relationships are as follows.

A total of 428 contributors have submitted codes for more than one main chain project. Through Fork relationship and the intersection of contributors, the technical relationship between public blockchain projects is formed. The individual technical capabilities of technical contributors are implicitly transferred among projects, among which 70 are related to the main chain projects.
