Satoshis provided as inputs to a transaction, but not consumed by its outputs, are collected by the coinbase transaction as implicit inputs. Satoshis provided as inputs to a transaction, but not consumed by its outputs, are collected by the coinbase transaction as implicit inputs.
The coinbase message is provided in the inputs unlocking script. The unlocking script is required to begin with a push of the block height which can then be followed why whatever data is desired. The block height encoded as a variable-length, little-endian integer. The [OP_DATA_X](/protocol/blockchain/script/op-codes/op-data-x) operation is used to push the necessary number of bytes to encode the length. This requirement was added with version 2 blocks as a part of [BIP-34](/protocol/forks/bip-0034). The coinbase message is provided in the inputs unlocking script.

## Miscellaneous Validation Rules
Bitcoin also has some miscellaneous rules for validation, which include exceptions or oddities.
The following are miscellaneous rules.
### Genesis Block Coinbase
The genesis block's coinbase may not be spent.
Furthermore, this coinbase's output is not considered an unspent transaction output.
### Extra Coinbase Validation Rules
Coinbases may only have one transaction input.
All coinbase unlocking script must be less than or equal to 100 bytes in size.
