Fiber-payjoin-kit: alignment with Fiber roadmap on collaborative privacy primitives

[Ile-Labs-T]

Hi Fiber team,

ILE Labs is working on fiber-payjoin-kit, a collaborative Payjoin-style privacy primitive for the CKB Fiber Network.

Before we continue deeper into implementation, we want to confirm that this direction aligns with the current Fiber roadmap, especially around privacy updates and channel-funding flows.

We are not trying to reinvent existing work. Our goal is to adapt collaborative funding concepts to CKB’s Cell model in a way that fits naturally with Fiber.

Could you please confirm whether this should move forward as a direct Fiber integration, an SDK extension, or another compatibility path?

Thank you.

Hi @chenyukang @quake @contrun and Fiber contributors — following up on this thread about fiber-payjoin-kit (PoC and architecture doc here: <link>). Can someone confirm whether collaborative channel-funding/privacy primitives fit Fiber’s current roadmap, or point us to the right contact/committee for a review? Thanks — @Ile-Labs-T
