projects rated by their code

darpal rating went through 133 blockchain projects and their codebases to make a rating based on development activity. it is based on number of commits, commit quality, popularity of the library, number of contributors and release frequency. the top looks like this:

1. lisk
2. eos
3. cardano
4. aeternity
5. ethereum
6. particl
7. bitcoin
8. augur
9. 0x
10. tron

the result is much cleaner than of cryptomiso, however i still see some problems with this list. it excludes forks, however particl is a bitcoin fork and tron is an ethereumj fork. tezos is not included in the list because is uses gitlab instead of github.
