Stateless VTXO Verification: Decoupling Custody from Implementation-Specific Stacks

Neil from Second has expressed appreciation for the proposal aimed at introducing more diversified methods for verifying the validity of VTXOs, highlighting its potential positive impact. He has directed attention to detailed responses available on their forum, providing a link for further reading. Neil clarifies two significant points in the discussion. Firstly, he addresses the misconception about Bark, Second's implementation of Ark, stating it is entirely open-source. This counters the argument that Bark operates within a proprietary environment or under what was termed "Implementation-Coupled Custody." Secondly, he dispels concerns related to mempool policy being a substantial obstacle. According to Neil, the adoption of package relay and CPFP (Child Pays for Parent) strategies for emergency exits by Bark effectively mitigates such challenges. Through these clarifications, Neil aims to correct misunderstandings and provide a clearer view of Second’s technological approach and its commitment to transparency and efficiency in the VTXO ecosystem.
