Lightning Funding Question

[jaybird777]

Trying to get up to speed on Lightning... Has SIGHASH_NOINPUT been activated as a means to create refund insurance on the initial multisig deposit (as described in the Lightning Whitepaper), or have devs found an alternative workaround that doesn't require a softfork?

No, it is currently an unactivated soft fork known as BIP 118. I don't think the devs have found a workaround, and are just waiting to see what happens, given that SIGHASH_NOINPUT was not a formal proposal in the past.

Before we can implement eltoo, we need a minor change to Bitcoin: the introduction of the SIGHASH_NOINPUT flag for signatures. This was first discussed a few months ago in the context of watchtowers to help secure Lightning channels, but was not formally proposed. A formal proposal may now be found in the eltoo paper.

Gotcha, so does that mean bi-directional LN channels are at a standstill until BIP 118 gets ratified?
