1 Criteria and Rating Scale

To evaluate and compare distributed ledger platforms a system of criteria hasbeen developed. According to these criteria, the activity of developing and sup-porting open source projects is evaluated, based on the corresponding GitHubrepositories.

Fig. 1 shows a list of repositories presented in our system. Fig. 3 presentsits matching to consensus algorithms.

The ranking is made on the following grounds:

3

Figure 4: Developers Activity score.

1. Developers Activity (fig. 4). The assessment considers data of 3 monthspreceding the time of assessment.

• The average number of code additions per week;

• The average number of commits per week;

• Last release date. An inverted scale is used for this item, that is,repositories with older releases are considered less active.

2. Feedback Activity (fig.5). For each issue i that has at least one commentfeedback activity FA reads:

FA =1

n

∑n

(closed at(i) − created at(i)),

where n is a number of commented issues, closed at(i) and created at(i)are dates of closing and creating of issue i.

4

Figure 5: Feedback Activity score.

In this criterion, we consider only those issues in which there is at leastone comment. Such a condition is imposed in order to avoid countingthose issues that developers put for themselves or for those that are closedbeyond prescription and non-relevance.

3. User Interest (fig. 6) is made up of:

• The number of forks;

• The number of developing forks. By developing forks, we mean thosethat do not have the same date of creation and the date of the up-date. This item shows the interest of users in the development of theproduct or creating their own based on it;

• The number of issues created in the last 3 months (including openissues);

• The number of stars.

Figure 7: Progress score.

4. Progress (fig. 7) consists of:

• The growth or decline ratio of the development activity is calculatedby the formula

D1 =1n3

∑n3

j3=1 commits per week(j3)1n1

∑n1

j1=1 commits per week(j1),

where n1 and n3 are numbers of weeks in one and three months,respectively, commits per week(j) is a number of commits in a weekj;

• Growth or decline ratio of the development team

D2 =1n3

∑n3

j3=1 committers per week(j3)1n1

∑n1

j1=1 committers per week(j1),

where n1 and n3 are numbers of weeks in one and three monthsrespectively, committers per week(j) is a number of contributorswho made any commit in a week j.

Note that the first two subclauses of criterion 1 are similar. We take bothof these points into account because we want to get a measure that does notdepend on the work style of developers with GitHub. For example, the presenceof a significant number of commits with smaller code changes in the repositorywill not lead to a high estimate. Also, on the contrary, in the case of active workof developers who rarely make commits, the rating will not be underestimated.To obtain a high or low estimate of developer activity, both of these values haveto be considered.

2 Data

We developed an automated information collection system. It obtains publicdata from repositories of distributed ledger platforms from GitHub using theGithub REST API v3. For more convenient monitoring of the project activity,the collected data is arranged in charts.

Histograms

• The number of contributors;

• The number of last year commits;

• The number of open issue;

• The number of ”stars”;

• The number of releases;

• The number of forks;

• The number of pull requests.

Diagrams

• Weekly commit statistics;

• Weekly issue closure statistics;

• Weekly additions and deletions statistics.
