The quantity paid out within the coinbase transaction is just not reward+charges.
The hyperlink you shared reveals
Enter Worth 3,067.86 BTC Output Worth 3,117.80 BTC
The distinction must be the reward claimed by the miner within the coinbase transaction, however the distinction is just 49.94
It additionally reveals
Minted 50.00 BTC Reward 50.05750000 BTC
So it does appear there’s a discrepancy.
I in contrast it with https://blockchair.com/bitcoin/block/163440
Enter complete 3,067.86 BTC Price complete 0.0575 BTC Era 49.94 BTC Output complete 3,117.80BTC
Notice the distinction between this explorer’s Era and blockchain.com’s Minted.
It reveals the output for the coinbase transaction as 50 BTC.
So I believe the miner forgot to assert the transaction charges and solely claimed the mining reward for the block.
I imagine the explorers wrongly interpret this because the miner having claimed 0.0575 BTC in charges and under-claimed roughly 49.94 BTC as a mining reward for the block. Blockchain.com reveals 50 as “Minted” – which is an inconsistency in its presentation. It reveals the entire reward that might have been claimed, not what was really claimed.
This under-claiming of rewards is throughout the Bitcoin guidelines, the miner can’t declare greater than block-reward plus transaction charges however they will declare much less.
