I have a rinkeby token, and I wanted to add "merged mining" when someone mines a block, they get awarded 0.25 of that token.

function issueBlockReward() {
balanceOf[block.coinbase] += 0.25;

The code above (I am missing the bottom closing tag) Awards the miner of an ethereum block 0.25 token. How can I make this run every 15 seconds? My pragma version is v0.4.21+commit.dfe3193c Thanks!

You basically already did it. As long as block reward will worth it, miners will include invocation of your function into every block they mine.

However, I see minor problem with your code. As long as all token balances and transfer amounts have to be integer, your block reward has to be integer as well.

  • Thanks! I have a slight problem though. It is returning an error! No matching declaration found after variable lookup. balanceOf[block.coinbase] += 1; – ETHguy Feb 12 at 23:40
  • Could you show the whole smart contract? – Mikhail Vladimirov Feb 13 at 6:19
