Bitcoin Fragment Sweep

PreviousBitcoin Fragment AddressNextClearing

Last updated 1 year ago

Intuitively, this sweep process works like commitmentTx in lightning, where the client always have an exit transaction available in case the counterparty refuses to respond.

In Boomerang, before a Fragment signs on the SweepTx, the new Fragment Judge proposes a Refund Transaction on the previous state of the reserve. Once all the new Fragment signatories sign on the refund transaction, the Sweep signing begins on the unlocked Fragment address.
