Unstable “legislation” EOS

After just a few weeks after the launch of EOS main technical project Director Dan Larimer has proposed to change its Constitution.

The arbitrators able to settle disputes directly, and the scope of their powers is not defined. Larimer proposes to limit their powers to address issues arising from differences between the code and the intentions and treatment of vulnerabilities and hacking code.
