I am creating a miner in C++ for solo mining, and am struggling to create the proper coinbase transaction.

Say I have a bc1 address, like bc1qfc7fameteuguetm0kfzypnvf2ju6wppdvj6tkc , what would be and example of a coinbase transaction with this, and how would I get to it?

| 00000000 ............................ Sequence // i thought this was all Fs?

01 .................................... Output count
| 2c37449500000000 .................... // coinbase value
| ????????????????? ............. // here, how do i properly fill this part??
| 00000000 ............................ Locktime

These are the parts needed to create the data for the transaction.

Everything up to the output, i understand. but i dont know what to put between the coinbase value and locktime. how does the address convert to hex? what OP codes do i need? and is this transaction layout correct?

And then I would then hash it and input it as a new transaction into the block as like so,

tx = {
  "data" : "<hex string mentioned above>",
  "hash" : "<double sha256 of data above>",
}

is that the only data i need for the json?

Thanks in advance.
