I am currently using Developer Environment for Hyperledger Fabrics. I tried using GET to retrieve block info and it does give me a response. However, in the response, there's one component called payload, and it's in an unreadable format. Is there a way to make it readable/decrypt it? For instance, in bluemix, when you do init of party "a" and party "b", the payload shows inita100b100.

Firstly, I did this transaction/REST request

{

  "jsonrpc": "2.0",

  "method": "invoke",

  "params": {

      "type": 1,

      "chaincodeID":{

          "name":"mycc"

      },

      "ctorMsg": {

         "function":"invoke",

         "args":["a", "b", "100"]

      }

  },

  "id": 3

}

Then I did this query request

GET/localhost:5000/transactions/c6b0c82d-27f9-4c2c-8305-34b413d95057

and got back this as REST response

{

  "type": 2,

  "chaincodeID": "EgRteWNj",

  "payload": "Ch8IARIGEgRteWNjGhMKBmludm9rZRIBYRIBYhIDMTAw",

  "uuid": "c6b0c82d-27f9-4c2c-8305-34b413d95057",

  "timestamp": {

    "seconds": 1469643763,

    "nanos": 524731069

  }

}

So if there's any way to decrypt/change Ch8IARIGEgRteWNjGhMKBmludm9rZRIBYRIBYhIDMTAw to showing A transferred 100 to b or something similar, at least being readable for less-technical users?

The payload is just encoded, you can use this to decode it (the encoding is base64). There is also this function in javascript to decode it.If you had security/privacy enabled, the payload would be encrypted too, so you would need the Certificate to decrypt the payload and then you could decode it.
