"There is no treasury. The Bitcoin is generated out of nothing."  Another way to put this is that when (the rules for) Bitcoin were created, they established 21M bitcoins to exist (and rules how to distributed those coins to the miners over the next few years). You can think of it is gold being hidden in the ground and the miners dig it out (with increasingly more difficulty over time, until eventually all 21M are in circulation).

<p>As Andrew Chow already explained, there is no treasury for bitcoin.</p>

<p>Any bitcoin amount in existence must be back-traceable through the whole blockchain to a valid origin. The only place where a transaction can validly output bitcoins that it didn't consume as input, is the miner's reward. So every amount in use can eventually be traced back to the so-called "coinbase transaction" (the miner's reward) of some block in the bitcoin history. The bitcoin rules limit the coinbase amount to currently 12.5 BTC, and if some miner tries to output more from a coinbase transaction, the others wouldn't accept that block, rendering his bitcoins invalid.</p>

<p>The miner adds the relevant block reward to himself (i.e. 12.5 bitcoin as of now) in something called the coinbase transaction.</p>

<p>Where do these 12.5 bitcoins come from? Does it comes from bitcoin treasury? If yes, then how is it issued? </p>

I read that response. It wasn't clear who mines the bitcoin for the block reward and hands to the miner? Is it completely the new bitcoins that are generated form the bitcoin treasury? If so, who does that? -------------------------- Non-technical and explanatory explanation please.

Where do these 12.5 bitcoins come from? Does it comes from bitcoin treasury? If yes, then how is it issued?
