As per section 13.a of the Hyperledger Charter all code submitted to the Hyperledger Foundation needs to have a Developer Certificate of Origin (DCO) sign-off.

The signoff needs to be using your legal name, not a pseudonym. Git has a built-in mechanism to allow this with the -s or --signoff argument to git commit command, providing your user.name and user.email have been setup correctly.

TL;DR:

If you don't want to break the DCO check, ensure all your commits have signoff.

git config user.name "FIRST_NAME LAST_NAME" git config user.email "[email protected]"

If you use GitHub web UI for commits, also ensure you have your email address set as public in your GitHub profile. This avoids issues with [email protected] placeholder emails.

You can also set up a git global alias.
