feature-bit channels This allows opening zero-conf chan-type, scid-alias chan-type, and scid-alias feature-bit channels. scid-alias chan-type channels are required to be private. Two paths are available for opening a zero-conf channel: * explicit chan-type negotiation * LDK carve-out where chan-types are not used, LND is on the receiving end, and a ChannelAcceptor is used to enable zero-conf When a zero-conf channel is negotiated, the funding manager: * sends a FundingLocked with an alias * waits for a FundingLocked from the remote peer * calls addToRouterGraph to persist the channel using our alias in the graph. The peer's alias is used to send them a ChannelUpdate. * wait for six confirmations. If public, the alias edge in the graph is deleted and replaced (not atomically) with the confirmed edge. Our policy is also read-and-replaced, but the counterparty's policy won't exist until they send it to us. When a scid-alias-feature channel is negotiated, the funding manager: * sends a FundingLocked with an alias: * calls addToRouterGraph, sends ChannelUpdate with the confirmed SCID since it exists. * when six confirmations occurs, the edge is deleted and re-inserted since the peer may have sent us an alias ChannelUpdate that we are storing in the graph. Since it is possible for a user to toggle the scid-alias-feature-bit to on while channels exist in the funding manager, care has been taken to ensure that an alias is ALWAYS sent in the funding_locked message if this happens. |
