THELOGICALINDIAN - Malta based bitcoin wallet account provider GreenAddress releasedsome cogent changes to their wallet architectonics over the accomplished few canicule which includedReplaceByFee RBF frontend transaction support
RBF allows bitcoin affairs to be flagged as dispensable until they are accepted in a block. For users who accelerate affairs with RBF angry on, it allows them to access the fees on the transaction for faster acceptance times, provided the transaction hasn’t already been confirmed.
Bitcoin Magazine writer Aaron van Wirdum gave a first-hand description of how GreenAddress RBF works in the wallet in recent tests he performed doing different transactions.
van Wirdum explained that RBF is angry on by absence in the wallet; users that don’t appetite to use RBF charge to manually about-face off this affection in the Settings panel. RBF is an opt-in policy, but abominably for GreenAddress users they are affected to opt-out by accepting to attenuate the feature. If they don’t, all affairs will be flagged as RBF. This isn’t necessarily a bad thing, depending on how the accepting wallet software handles it; and if the sender isn’t aggravating to double-spend the transaction.
In the awning abduction above, it shows in GreenAddress that if you bang the “bump fee” tab you are presented with a few options to bang your fee up to be included in the abutting block(s), or as van Wirdum describes it, you can “boost” your transaction.
In added of the testing, it was apparent that not all bitcoin miners are acknowledging RBF yet. 75% of miners according to the analysis affairs are not acknowledging RBF, with 20% that are. Additionally, not all wallets are acknowledging RBF yet. Recently Airbitz appear their Matterhorn update, which includes RBF transaction detection. So for archetype if a user from GreenAddress wallet sends an RBF-enabled transaction to addition being application the Airbitz wallet, the Airbitz wallet will ascertain this blazon of transaction and acquaint the user of it.
This is an important workflow for users accepting RBF-enabled transactions. If the being on the accepting end of the RBF-enabled transaction doesn’t delay at atomic one confirmation, the being sending the transaction could in approach do the replace-by-fee advantage in an attack to double-spend the transaction, paying alone the change address.
