As you know, the witness is rewarded for produce a block. The TOP 20 gets to produce the blocks more frequently than the backup witnesses, but the reward for each block is different: currently 484 VESTS for TOP 20 while around 2425 VESTS for others on the steem blockchain.
How do we get the reward given a block number? Unfortunately, it is not through the `get_block` api. Instead, we need to use `get_ops_in_block` which is provided by `account_plugin_history`
1 | curl -s --data '{"jsonrpc":"2.0", "method":"condenser_api.get_ops_in_block", "params":[43880000,true], "id":1}' https://api.steemit.com |
curl -s --data '{"jsonrpc":"2.0", "method":"condenser_api.get_ops_in_block", "params":[43880000,true], "id":1}' https://api.steemit.com
This returns like:
{"jsonrpc":"2.0","result":[{"trx_id":"0000000000000000000000000000000000000000","block":43880000,"trx_in_block":4294967295,"op_in_trx":0,"virtual_op":1,"timestamp":"2020- 06-01T17:49:18","op":["producer_reward",{"producer":"hinomaru-jp","vesting_shares":"481.663694 VESTS"}]}],"id":1}
Then, we can wrap it up in a Python function (please note that we need to scan the transactions array and look for the `producer_reward` ops.
