채널 구성에는 채널 관리와 관련된 모든 정보가 포함됩니다. 가장 중요한 것은 채널 구성은 채널의 구성원인 조직(org)을 지정하지만 채널 액세스 정책 및 블록 배치 크기와 같은 다른 채널 전체 구성 정보도 포함합니다.
구성은 블록으로 저장되기 때문에 구성 업데이트는 "구성 트랜잭션(configuration transaction)"이라는 프로세스를 통해 발생합니다(프로세스가 일반 트랜잭션과 약간 다르긴하지만). 구성 업데이트는 구성을 가져 와서 사람이 읽을 수 있는 형식으로 변환하고 수정한 다음 승인을 위해 제출하는 과정입니다.
채널은 구성 가능하지만 무한대 아닙니다. 다른 구성 요소에는 다른 수정 정책(구성 업데이트에 서명하는 데 필요한 ID 그룹 지정)이 있습니다.

설정은 이 형식으로 위협적으로 보일지 모르지만 일단 그것을 공부하면 논리 구조가 있음을 알 수 있습니다.
채널 수준에서 특정 작업을 수행 할 수 있는 사람을 정의하고 구성 채널을 변경할 수 있는 사람을 변경할 권한이 있는 정책의 정의 외에도 구성 업데이트를 사용하여 수정할 수 있는 다른 종류의 기능이 있습니다. Adding an Org to a Channel(채널에 조직 추가) 과정은 채널을 조직에 추가하는 등 가장 중요한 작업 중 하나를 수행할 수 있습니다. 구성 업데이트로 변경할 수 있는 몇 가지 다른 사항은 다음과 같습니다.
Org에 아티팩트 및 MSP 정보를 추가하는 것 처럼 프로세스를 되돌려 제거할 수 있습니다.
채널의 블록 일괄 처리 크기(block batch size)를 편집하고자 한다고 가정해봅시다(단일 숫자 필드이기 때문에 가장 쉬운 변경사항 중 하나입니다). 먼저 JSON 경로를 쉽게 참조할 수 있도록 환경 변수로 정의합니다.
이것을 설정하려면 설정을 살펴보고 원하는 것을 찾은 다음 경로를 추적하십시오.
이제 새 batch size를 설정하고 새 값을 표시합니다.
protobuf 파일을 성공적으로 생성했으면 서명을 해야 합니다. 이렇게 하려면 변경하려고 하는 모든 정책에 대한 관련 정책을 알아야합니다.
채널의 기본 정책을 변경한 경우 이에 따라 서명 요구 사항을 계산해야합니다.
이러한 서명을 얻는 실제 프로세스는 시스템을 설정한 방법에 따라 다르지만 두 가지 주요 구현이 있습니다. 현재 패브릭 명령 줄의 기본값은 "pass it along" 시스템입니다. 즉, 조직의 Admin이 구성 업데이트를 제안하면 서명해야하는 다른 사람 (일반적으로 다른 Admin)에게 업데이트를 보냅니다. 이 Admin은 서명 (또는 서명하지 않음) 한 후 다음 Admin에게 전달하며, 구성을 제출하기에 충분한 서명이있을 때까지 계속합니다.
이것은 단순성 덕분입니다. 충분한 서명이 있을 때 마지막 Admin은 config 트랜잭션을 제출하기 만하면됩니다 (Fabric에서는 peer channel update 명령이 기본적으로 서명을 포함합니다). 그러나 이 과정은 작은 채널에서만 실용적일 것입니다. 왜냐하면 "pass it along" 방법은 시간이 오래 걸릴 수 있기 때문입니다.
다른 옵션은 채널의 모든 Admin에게 업데이트를 제출하고 충분한 서명이 다시 오기를 기다리는 것입니다. 이 서명들은 함께 꿰매어 제출할 수 있습니다. 이로 인해 구성 업데이트를 만든 Admin(서명자 당 파일을 처리해야 함)에게는 다소 어려움이 있지만 Fabric 관리 응용 프로그램을 개발하는 사용자에게는 권장되는 워크 플로입니다.
설정이 원장에 추가되면 모든 것을 올바르게 추가했는지 확인하기 위해 pull 해서 JSON으로 변환하는 것이 가장 좋습니다. 이것은 최신 설정의 유용한 복사본으로도 사용됩니다.
