I got lost in reading this transaction: a tx from blockchain.com
This transaction does not have an input address, instead, it says "COINBASE (Newly Generated Coins)". Is it a block reward to the miner? But the amount does not add up, since it is 6.71380828 BTC rather than 6.25. Another address as shown here OP_Return with same amount This address transfers the same amount to the same address for every block (1111111111111111111114oLvT2 0.00137500 BTC) after the OP_Return mark. Since Wikipedia said OP_Return means invalid transactions and these transfers are often marked spend. I'm wondering are these valid transactions? Otherwise, how can they be spent? Can anybody help me out in reading these two transactions? Thanks a lot!
