Reward, Rate ,Fraction and Proposer

General
1

I have set up my own node and was trying to find out the block info using the below CURL:
curl -v http://xxx/v1/block/4795723 -H "X-Algo-API-Token:xxx"

I want to know about the Reward, Rate ,Fraction and Proposer.

  • As per the 12 rewards period (500,000 blocks in each period) in Algorand . This particular block falls in the 10th reward period where each block will get 72 Algo , but as per this block info the blockreward is 103745. Can any one explain on the block reward mismatch or the info i have is totally wrong (12 reward period info.)

  • Can any one explain me rate, fraction and proposer.

Hi @debasish,

The reward field specifies how many rewards, in MicroAlgos, have been distributed to each Algo since genesis. See https://github.com/algorand/go-algorand-sdk/blob/32dccacfceedfa473edfc9a69101237f1cecb69f/client/algod/models/models.go#L445

The fields frac and rate are explained in https://github.com/algorand/go-algorand-sdk/blob/32dccacfceedfa473edfc9a69101237f1cecb69f/client/algod/models/models.go#L448.

To understand better reward distribution, see https://www.algorand.com/resources/blog/rewards-technical-overview.

The proposer field is the address of the account that proposed the block. See https://developer.algorand.org/docs/algorand_consensus/#block-proposal

@fabrice i did not understand - “have been distributed to each Algo since genesis” i.e why microalgos have beed distribuited to each Algo

If you had an account with 1 Algo in the genesis block, you would have received this number of micro Algos (assuming you never made any transaction).
