背书政策何时生效?相关的系统链码是什么?

When does the Endorsement Policy take place? What are the relevant System Chain Codes?

我引用了网页:http://hyperledger-fabric.readthedocs.io/en/latest/arch-deep-dive.html

我想问一下这张照片和代言政策。

在该网站的2.3部分,出现了以下声明。而这与图③有关

"The exact number of “enough” depend on the chaincode endorsement policy"

并且在本网站的2.4节中,为同行出现了以下声明。这与图片的④有关。

It checks that the blob.endorsement is valid according to the policy of the chaincode (blob.tran-proposal.chaincodeID) to which it refers.

问题

  1. ③背书政策和④背书政策有什么区别 链码?
  2. ESCC是否与③相关,④与VSCC相关?

Question

  1. What is the difference between an ③ endorsement policy and ④ a policy of the chaincode?

在第 3 阶段,对等点实际进行背书,即字面上对链代码调用的结果进行签名。而在 4 时,这是在提交时发生的,其中对等方确保只要背书策略得到满足。

注意:由客户收集所需数量的背书。

  1. Is ESCC related to ③, and ④ related to VSCC?

是的,ESCC or Endorsement System ChainCode is the actually a system chaincode which responsible to "endorse" transaction, where VSCC 或验证系统 ChainCode 是一个系统链码,用于在满足背书策略时进行检查。
