EMERGENCY: RealityRipple Software is in need of assistance! Due to unexpected and major power problems, all project development and technical support is on hold indefinitely. Any donations would be incredibly appreciated at this time.

Did you know that RealityRipple Software is solar-powered software? Since 2003, RealityRipple Software has been run off-grid, relying on independently owned and operated solar panels, batteries, and a backup propane generator, while providing a negative carbon footprint by preserving over 200 acres of untouched forest.
Please consider making a donation to keep RealityRipple Software running!

Need to verify ownership of an address? Use this tool to authenticate messages from Base58 addresses. Currently supports Bitcoin, Bitcoin Cash (works with CashAddr!), Bitcoin Gold, Dogecoin, Litecoin, Dash, DigiByte, Ripple, and Zcash.
