♻️ Re-creation of #8982, which was auto-closed on 2026-08-11 when my fork was detached from the repository network (GitHub cannot reopen PRs closed by a detachment). Branch content is unchanged (head 5ae3369d3); the previous review discussion remains on #8982.

Summary

  • Add announce parameter to setchannel RPC to upgrade private channels to public
  • When both peers set announce=true, the channel enters the public announcement flow (exchange announcement_signatures, wait for 6 confirmations, broadcast channel_announcement)
  • Announcement signatures received while a channel is private are now stashed instead of rejected, enabling seamless upgrade when the peer upgrades first

Details

The channel gossip state machine gains three new transitions from CGOSSIP_PRIVATE:

  • CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_MATCHING_PEER_SIGS (normal case)
  • CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_ANNOUNCE_DEPTH (peer sigs already received)
  • CGOSSIP_PRIVATE -> CGOSSIP_ANNOUNCED (peer sigs received + 6 confirms already reached)

Setting announce=false is rejected since public-to-private conversion is not possible.

Fixes#7438

Test plan

  • CI passes (build + unit tests)
  • Manual test: open private channel, call setchannel <id> announce=true on both sides, verify channel gets announced
  • Verify setchannel with announce=false returns error
  • Verify announcement_signatures from peer are stashed when channel is private

Add an `announce` parameter to the `setchannel` RPC command that allows
upgrading an existing private (unannounced) channel to a public
(announced) channel. When set to true, the channel_flags are updated
to set the CHANNEL_FLAGS_ANNOUNCE_CHANNEL bit, and the gossip state
machine transitions from the private states into the public announcement
flow.
Both peers must independently set announce=true for the channel
announcement to complete, as the protocol requires announcement
signatures from both sides. To facilitate this, announcement_signatures
received while a channel is still private are now stashed rather than
rejected, so they are available immediately if/when the local side
upgrades.
State transitions added:
- CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_MATCHING_PEER_SIGS
- CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_ANNOUNCE_DEPTH
- CGOSSIP_PRIVATE -> CGOSSIP_ANNOUNCED
Setting announce=false (public to private) is rejected as this is not
possible once a channel has been announced.
Changelog-Added: `setchannel` now accepts an `announce` parameter to upgrade private channels to public.
Fixes #7438

♻️ Re-creation of #8982, which was auto-closed on 2026-08-11 when my fork was detached from the repository network (GitHub cannot reopen PRs closed by a detachment). Branch content is unchanged (head 5ae3369d3); the previous review discussion remains on #8982.

Summary

  • Add announce parameter to setchannel RPC to upgrade private channels to public
  • When both peers set announce=true, the channel enters the public announcement flow (exchange announcement_signatures, wait for 6 confirmations, broadcast channel_announcement)
  • Announcement signatures received while a channel is private are now stashed instead of rejected, enabling seamless upgrade when the peer upgrades first

Details

The channel gossip state machine gains three new transitions from CGOSSIP_PRIVATE:

  • CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_MATCHING_PEER_SIGS (normal case)
  • CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_ANNOUNCE_DEPTH (peer sigs already received)
  • CGOSSIP_PRIVATE -> CGOSSIP_ANNOUNCED (peer sigs received + 6 confirms already reached)

Setting announce=false is rejected since public-to-private conversion is not possible.

Fixes#7438

Test plan

  • CI passes (build + unit tests)
  • Manual test: open private channel, call setchannel <id> announce=true on both sides, verify channel gets announced
  • Verify setchannel with announce=false returns error
  • Verify announcement_signatures from peer are stashed when channel is private

Add an `announce` parameter to the `setchannel` RPC command that allows
upgrading an existing private (unannounced) channel to a public
(announced) channel. When set to true, the channel_flags are updated
to set the CHANNEL_FLAGS_ANNOUNCE_CHANNEL bit, and the gossip state
machine transitions from the private states into the public announcement
flow.
Both peers must independently set announce=true for the channel
announcement to complete, as the protocol requires announcement
signatures from both sides. To facilitate this, announcement_signatures
received while a channel is still private are now stashed rather than
rejected, so they are available immediately if/when the local side
upgrades.
State transitions added:
- CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_MATCHING_PEER_SIGS
- CGOSSIP_PRIVATE -> CGOSSIP_WAITING_FOR_ANNOUNCE_DEPTH
- CGOSSIP_PRIVATE -> CGOSSIP_ANNOUNCED
Setting announce=false (public to private) is rejected as this is not
possible once a channel has been announced.
Changelog-Added: `setchannel` now accepts an `announce` parameter to upgrade private channels to public.

Superseded by #9428 — recreated from the public fork because this PR's head repo is now private and GitHub cannot reopen it.
