Consulting heavyweight Deloitte claims that over 26,000 new blockchain-based projects were launched on GitHub in 2016.
According to Deloitte, the majority of the projects, however, have become inactive in the long run and only eight percent are active so far.
The stark reality of open-source projects is that most are abandoned or do not achieve meaningful scale. Unfortunately, blockchain is not immune to this reality. Our analysis found that only eight percent of projects are active, which we define as being updated at least once in the last six months.
Based on the said report, the leading cryptocurrency Bitcoin has unsurprisingly posted the most number of activities, with 627 total contributors and almost 12,000 followers. Go Ethereum (Geth), meanwhile, has attracted 149 contributors, as well as 5,603 followers so far. Geth is a software client that is maintained by the nonprofit group Ethereum Foundation.
