  1. I take it the SIGs are meant to be subgroups of the TWGC focusing on different topics, is that right?

    What does "GM" stand for in "Fabric RFC for GM support"?

    1. that's correct, sigs are sub-groups within TWGC.

      GM = China National Cryptographic Standards

      (it's the abbreviation of Guo Mi, pinyin version of this cryptographic standards. We are using GM instead of proper English text since it's used mostly in local context and much more prevalent)

      1. Ok, that's what I suspected but thanks for clarifying.

  2. Re: Tools developed for Fabric performance test

    The projects listed under here are great for the larger community as a whole. TWGC can consider recommending space under Hyperledger Labs for these projects. It will give bigger exposure and attract like minded folks to contribute. These repositories in addition to the projects placed under are examples of great contributions. This was also brought up during the TSC meeting. I would join Tracy Kuhrt and extend my support/sponsorship to such initiatives.
