Sources linked cryptographically

[mitfik]

Progressing on the implementation and research in the scope of microledger we realize to gain full security of ACDC we need to use SAI for linking sources as well otherwise we are pointing to sources which are not stable. Currently attestation id is defined as:

  i - identifier, which can be designated by Testator to uniquely track specific attestation. ADID is always within namespace of the Testator Identifier making it always globally unique.

and to assure about secure linking mechanism it should be simply defined as SAI. Having human readable/meaningful identifier is still desire so we could keep it as addition attribute which could be introduce ai - attestation identifier which would be define same as currently i

So the proposition is to use it in a way:

s: {
       i: SAI, ti: DID_of_testator, ai: ATTESTATION_ID
    }

where:

• i - SAI which cryptographically binds to the content of the ACDC,
• ti - testator identifier [optional if ai would be within the namespace of testator]
• ai - identifier, which can be designated by Testator to uniquely track specific attestation. ADID is always within namespace of the Testator Identifier making it always globally unique.
