Popular mobile and web-based bitcoin wallet service provider Breadwallet has released update 0.5.3, featuring more efficient transaction confirmations and improved security protocols.
The newest version of both the web and mobile application reduces memory usage greatly, optimizes core-data performance and app startup speed (on mobile phone), and enables the smart detection of bitcoin nodes which fail to follow standard network relay rules, offering a whole new level of maintenance and stability.
