In a coinbase transaction, the first two fields are set to values that
do not represent a UTXO reference. Instead of a "transaction hash," the
first field is filled with 32 bytes all set to zero. The "output index"
is filled with 4 bytes all set to 0xFF (255 decimal). The "Unlocking
Script" (+scriptSig+) is replaced by coinbase data, a data field used by
is filled with 4 bytes all set to 0xFF (255 decimal). The
+scriptSig+ is replaced by coinbase data, a data field used by
the miners, as we will see next.
==== Coinbase Data
((("coinbase transactions", "coinbase data")))Coinbase transactions do
not have an unlocking script (aka, +scriptSig+) field. Instead, this
not have a +scriptSig+ field. Instead, this
field is replaced by coinbase data, which must be between 2 and 100
bytes. Except for the first few bytes, the rest of the coinbase data can
be used by miners in any way they want; it is arbitrary data.
