@cbruguera The reason it is not a separate agreement is that any Identity Owner can become a Trust Anchor. So we needed to make it part of the Identity Owner Agreement. Trust Anchor Obligations is in fact a defined term in the Provisional Trust Framework, and they are defined in this section of the Provisional Trust Framework Public Review Draft 01.
In the proposed new language for Identity Owner Obligations that I posted last night for Public Review Draft 02, it says (emphasis added):
That attestation is called a Trust Anchor Connection, and yes, you are correct that in the Provisional Network only one Trust Anchor Connection is required to become a Trust Anchor.
But that’s a very simple rule intended only for the first stage of the network when it is still small and “everyone knows your name” (as the Cheers theme song put it). As the network grows, the Sovrin Board of Trustees should be able to change the threshold number of Trust Anchor Connections needed for an Identity Owner to qualify as a Trust Anchor. This policy has already been added to the second Public Review Draft being prepared for the Trust Framework Working Group to review tomorrow (Tuesday).
The short answer is “Yes, absolutely”. This is what the Sovrin Web of Trust model is all about—how to design the Sovrin Trust Graph so that is helps protect a distributed web of trust relationships in much the same way the Sovrin ledger helps protect a distributed database of transaction records.
But in large part we decided to put that policy definition work out of scope for the Provisional Trust Framework so that we could finish it quickly. Once that is done, defining the rest of the policies for the Sovrin Web of Trust will IMHO be the majority of the work remaining to complete the Sovrin Trust Framework V1 that will govern the General Availability Network.
I completely agree. IMHO Trust Anchors will be the heros of the Sovrin Network (keep in mind that every Trustee and Steward is automatically a Trust Anchor). I look forward very much to working with you and the rest of the Trust Framework Working Group to make it so.
