-Bitcoin Chain Processing Overview
+# Bitcoin Chain Processing Overview
 
 Before a block is allowed into the block chain, it must go through an intensive
 series of validation rules.  The following list serves as a general outline of
 those rules to provide some intuition into what is going on under the hood, but
 is by no means exhaustive:
 
- - Reject duplicate blocks
- - Perform a series of sanity checks on the block and its transactions such as
-   verifying proof of work, timestamps, number and character of transactions,
-   transaction amounts, script complexity, and merkle root calculations
- - Compare the block against predetermined checkpoints for expected timestamps
-   and difficulty based on elapsed time since the checkpoint
- - Save the most recent orphan blocks for a limited time in case their parent
-   blocks become available
- - Stop processing if the block is an orphan as the rest of the processing
-   depends on the block's position within the block chain
- - Perform a series of more thorough checks that depend on the block's position
-   within the block chain such as verifying block difficulties adhere to
-   difficulty retarget rules, timestamps are after the median of the last
-   several blocks, all transactions are finalized, checkpoint blocks match, and
-   block versions are in line with the previous blocks
- - Determine how the block fits into the chain and perform different actions
-   accordingly in order to ensure any side chains which have higher difficulty
-   than the main chain become the new main chain
- - When a block is being connected to the main chain (either through
-   reorganization of a side chain to the main chain or just extending the
-   main chain), perform further checks on the block's transactions such as
-   verifying transaction duplicates, script complexity for the combination of
-   connected scripts, coinbase maturity, double spends, and connected
-   transaction values
- - Run the transaction scripts to verify the spender is allowed to spend the
-   coins
- - Insert the block into the block database
