README.mediawiki

Here we discuss Bitcoin Improvement Proposals (BIPs) that have made or could make their way into Dash generally from an downstream merge from Bitcoin Core.

You can not submit BIPs into Dash. The name for Dash Improvement Proposals are DIPs and they are Dash specific.

Having a BIP referenced here does not mean it was formally accepted in the Bitcoin ecosystem unless its status is Final or Active.

One should note 2 types of statuses, Bitcoin Status and Dash Status. Dash statuses can be one of the following:

  • Accepted - Kept from bitcoin, but not yet implemented.
  • Partial - Kept from bitcoin, implemented partially. Notes should explain in the BIP current progress.
  • Active - Kept from bitcoin, fully implemented.
  • Ignored - Not applicable to DASH or previously withdrawn from Bitcoin.
  • Rejected - Accepted or Final in Bitcoin but Rejected in DASH.
2 Keywords can also give more information, they will preceed the Status: (ie Extended Partial).

  • Extended - Kept from bitcoin with extensions to meet DASH network demands.
  • Modified - Kept from bitcoin and slightly modified.

* BIP is not Bitcoin or Dash specific (i.e. BIP-0044 Multi-Account Hierarchy for Deterministic Wallets). Generally relates to the Application Layer and not specifically the reference client.
