X-Headers-End: 1TiuPC-0004ZJ-Gl Subject: [Bitcoin-development] RFC: Updating dust output definition, and default fees X-BeenThere: bitcoin-development@lists.sourceforge.net X-Mailman-Version: 2.1.9 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 12 Dec 2012 22:03:58 -0000 URL: https://github.com/bitcoin/bitcoin/pull/2100 1) Create COIN_DUST constant, to represent the dust spam limit used. 2) Decrease COIN_DUST to 0.001 BTC Rationale: With the increase in bitcoin value (US$13.67 as of this writing), it seems reasonable to reduce the value level of which we consider "dust spam." 3) Update TX miner and relay fee defaults to 0.001 / 0.0005 BTC respectively Rationale: Reflects growth of dust spam in unspent transaction output dataset. Review of impact: a) Definition of COIN_DUST reduced from 0.01 to 0.001. b) Miners who mine with this code will require a fee >= 0.001 to include TX's with outputs <= COIN_DUST c) Normal clients will require a fee >= 0.0005 to relay TX's with outputs <= COIN_DUST -- Jeff Garzik exMULTI, Inc. jgarzik@exmulti.com
