As soon as the last block was created (by solving proof of work algorithm), the miners immediately try to find the hash to create the next block. They do not waste even one second.
This miner was just lucky, he found it in 4 seconds, before his mempool was filled with transactions.

usually this only happens if two blocks are found relatively quickly in succession, so it probably isn't the culprit here. this block was found 4 minutes after the previous so i'm curious why it was empty.
I think you mean 4 seconds

i'm not sure how common "spy mining" is anymore, but it used to be a major source of empty blocks.
basically, pools want their miners to mine on top of the next block ASAP. so they connect to competing pools and "spy" on them, and when a block is found, they mine on top of the header. since they don't validate the block this way, they can only mine empty blocks on top of it to avoid including double-spend transactions in the next block.

The miner who “finds” a block will be rewarded in two ways
1) The block subsidy that decreases by half every approximately 4 years (every 210,000 blocks). It was originally 50 btc per block, was later reduced to 25 btc per block, and is now 12.5 btc per block. In about a year, it will be further reduced to 6.25 btc per block.
2) transaction fees paid by users of bitcoin. In order to get the miner to confirm transactions users include a fee that goes to the miner who includes the transaction in their found blocks.
If the miner doesn’t include any transactions in their found blocks except the Coinbase transaction, he will only be compensated with the block subsidy described in 1 above.

... It's rare?
It's simply an empty block... It isn't super common, but it does occur relatively often. Quote
How possible happend with that? Then how about reward miners?
Miner still gets the full 12.5 BTC as the block reward. They just don't get fees. But the actual block reward is the main component of the total reward anyway... a lot of blocks are in the 13 BTC reward range even with fees... so miner is only "missing" ~0.5 BTC for mining an empty block in that instance.
Hey Im bit confused with block https://www.blockchain.com/btc/block/0000000000000000001288ba62a1cd6804f55ec96cfe346c2a815b5743e3c7db # 579419 . The block only had 1 transaction.
Edit : Sorry just did a reseach. Following statement :
Edit : Sorry just did a reseach. Following statement :
It simply means that at the time the block was built, the miner simply chose not to include any other transactions. It could simply be because the miner knew of the previous block but had not processed it yet so it did not know what transactions were included so none were included. Since it probably did not exhaust all of the possible nonces, the block remained empty since there was no need to have to rebuild the block to get a different hash.
My point is, does blocks works / find a good hash based all trasactions collected then locked by nonce? It's rare? How possible happend with that? Then how about reward miners? Jump to:
