Struct lightning::util::config::ChannelHandshakeConfig

pub struct ChannelHandshakeConfig {
    pub minimum_depth: u32,
    pub our_to_self_delay: u16,
}

Configuration we set when applicable.

Default::default() provides sane defaults.

Fields

minimum_depth: u32

Confirmations we will wait for before considering the channel locked in. Applied only for inbound channels (see ChannelHandshakeLimits::max_minimum_depth for the equivalent limit applied to outbound channels).

Default value: 6.

our_to_self_delay: u16

Set to the amount of time we require our counterparty to wait to claim their money.

It's one of the main parameter of our security model. We (or one of our watchtowers) MUST be online to check for peer having broadcast a revoked transaction to steal our funds at least once every our_to_self_delay blocks.

Meanwhile, asking for a too high delay, we bother peer to freeze funds for nothing in case of an honest unilateral channel close, which implicitly decrease the economic value of our channel.

Default value: BREAKDOWN_TIMEOUT (currently 144), we enforce it as a minimum at channel opening so you can tweak config to ask for more security, not less.
