 ACDCs were invented by Sam Smith, with collaboration from Phil Fairheller and others in the Trust Over IP and Web of Trust communities. Trust Over IP is an initiative of the Linux Foundation. Sam is a co-inventor of Sovrin with significant experience at Consensys and in other cybersecurity and blockchain-related initiatives. He also wrote the RAET protocol that was a key component of SaltStack. Via their sponsorship by GLEIF, which was in turn commissioned by the G20's Regulatory Oversight Committee, ACDCs are more connected to global banking and less connected to big tech or to classic identity technologies.
 
 ### 2.7 Standards path
-SD-JWTs are being standardized at IETF, where JWT, JWS, and JWK were standardized years ago. Multiple draft RFCs are involved, and their maturity differs. None are standards yet, but they do have sponsoring workgroups, and they are likely to become public standards-oriented RFCs at some point in the future. Implementations are very young, but Microsoft's enthusiasm seems likely to produce gravitas.
+SD-JWTs are being standardized at IETF, where JWT, JWS, and JWK were standardized years ago. At least two different draft RFCs are involved, and their maturity differs. They are not standards yet, but they do have sponsoring workgroups, and they are likely to become public standards-oriented RFCs at some point in the future. Implementations are very young, but Microsoft's enthusiasm seems likely to produce gravitas.
 
 The recommended approach to schemas in SD-JWTs (standardizing collections of claims with their associated names, data types, occurrence rules, and semantics) is to register them with IANA. This is a separate step from standardizing the general technology.
