Hi all,

Earlier this year, I emailed this mailing list about bitcoin Lightning
Improvement Proposals (bLIPs) [1] as a way to help standardize
community-driven app layer and protocol extension development. Today, I am
excited to let you know that the first two bLIPs specifying the process
have been merged [2] and that we are ready to start receiving proposals!

Here are few example proposals I have my eyes on: Val's Keysend bLIP [3],
the Sphinx team's LUMO messaging format [4], Satoshi's Stream's TLV
registry [5], Lightning Node Connect [6], niftynei's accounting
standardization work, some of Impervious's LN-native communications
work, LND's Static Channel Backup system... and I am sure there are many
more!

Please don't hesitate to reach out if you're interested in writing a bLIP
and want help. We're excited about getting this process going!

As a reminder, a bLIP is a design document providing information to the
Lightning community, or describing a new feature for the Lightning Network,
and should provide a concise technical specification of the feature and a
rationale for the feature. Importantly, if a feature is intended to become
universal or near universal, it must be a BOLT [7].

Because of this distinction, the bLIP editors do not pass judgment on
bLIPs, but only monitor bLIP changes, and update bLIP headers as
appropriate. So long as you check the mailing list to ensure nobody has
made a similar proposal before, fill out the required sections specified in
bLIP-0001, and reserve the required feature bit, message type, or TLV in
the bLIP-0002 registry, we are more than happy to merge proposals into the
repo.

Best,
Ryan

Hi all,

Thanks so much for the great feedback over the last week. Seems like
general agreement that adding a simple home for descriptive design
documents focusing on new LN features would be a good thing, and augment
the prescriptive BOLTs (which have done a great job getting us this far!).

If there is a point of contention, it seems to be about how not only this
interacts with the existing BIP system, but also how the BOLTs interact
with the BIP system. The only problem I have with BOLTs and bLIPs as BIPs
is that it introduces large scope creep over what was originally a pretty
simple proposal. I don't really care where these design documents exist,
only that there is a standard format and that LN developers and users feel
empowered to create them and share them with the broader ecosystem.

If we proceed with creating bLIPs in the lightning-rfc repo today and later
decide to recreate the BOLTs as BIPs, it will be no trouble at all to
recreate bLIPs as BIPs as well.

The BIP Process Wishlist sounds great and can be addressed independently.
If recruits for merging the BOLTs can be found, we can tackle the mechanics
of a merge then (alongside maybe some of the other bitcoin-related *IP
repos that exist outside the BIPs? [1] [2]).

Best,
Ryan

Hi Rene,

Thank you for the feedback! Very interesting to look back at the same
proposal from 2018, we clearly could have done a better job researching
past attempts. I have two main comments:

1) not trying to introduce a new repo, the linked lightning-rfc branch [1]
simply adds a new bLIPs folder in the existing repo (like you suggested as
an option in 2018)
2) major difference between 2018 and now is one of scale (which is a great
problem to have!). In 2018 the LN dev ecosystem was mostly ACINQ,
Blockstream, and Lightning Labs and the minimalist BOLTs process worked
well. At this point the broader ecosystem is significantly bigger than
those three teams combined, and it seems the process should adjust to
reflect the new environment.

The main goal of the suggested change is simply to provide a home for
emerging "best practices", especially those that require coordination
amongst multiple groups. I think LNURL provides a good example of a "best
practice" that has been spec'd out [2], is completely extra protocol so
probably doesn't belong as a BOLT, but carries tension with it for new
developers since it's been widely adopted yet not "officially supported".
What do you think about that?

Best,
Ryan

Hi all,

The recent thread around zero-conf channels [1] provides an opportunity to
discuss how the BOLT process handles features and best practices that arise
in the wild vs. originating within the process itself. Zero-conf channels
are one of many LN innovations on the app layer that have struggled to make
their way into the spec. John Carvalho and Bitrefill launched Turbo
channels in April 2019 [2], Breez posted their solution to the mailing list
for feedback in August 2020 [3], and we know at least ACINQ and Muun
(amongst others) have their own implementations. In an ideal world there
would be a descriptive design document that the app layer implementers had
collaborated on over the years that the spec group could then pick up and
merge into the BOLTs now that the feature is deemed spec-worthy.

Over the last couple of months, we have discussed the idea of adding a
BIP-style process (bLIPs? SPARKs? [4]) on top of the BOLTs with various
members of the community, and have received positive feedback from both app
layer and protocol devs. This would not affect the existing BOLT process at
all, but simply add a place for app layer best practices to be succinctly
described and organized, especially those that require coordination. These
features are being built outside of the BOLT process today anyways, so
ideally a bLIP process would bring them into the fold instead of leaving
them buried in old ML posts or not documented at all.

Some potential bLIP ideas that people have mentioned include: each lnurl
variant, on-the-fly channel opens, AMP, dynamic commitments, podcast
payment metadata, p2p messaging formats, new pathfinding heuristics, remote
node connection standards, etc.

If the community is interested in moving forward, we've started a branch
[5] describing such a process. It's based on BIP-0002, so not trying to
reinvent any wheels. It would be great to have developers from various
implementations and from the broader app layer ecosystem volunteer to be
listed as editors (basically the same role as in the BIPs).

Looking forward to hearing your thoughts!

Best,
Ryan

Hi all,

Thanks so much for the great feedback over the last week. Seems like
general agreement that adding a simple home for descriptive design
documents focusing on new LN features would be a good thing, and augment
the prescriptive BOLTs (which have done a great job getting us this far!).

If there is a point of contention, it seems to be about how not only this
interacts with the existing BIP system, but also how the BOLTs interact
with the BIP system. The only problem I have with BOLTs and bLIPs as BIPs
is that it introduces large scope creep over what was originally a pretty
simple proposal. I don't really care where these design documents exist,
only that there is a standard format and that LN developers and users feel
empowered to create them and share them with the broader ecosystem.

If we proceed with creating bLIPs in the lightning-rfc repo today and later
decide to recreate the BOLTs as BIPs, it will be no trouble at all to
recreate bLIPs as BIPs as well.

The BIP Process Wishlist sounds great and can be addressed independently.
If recruits for merging the BOLTs can be found, we can tackle the mechanics
of a merge then (alongside maybe some of the other bitcoin-related *IP
repos that exist outside the BIPs? [1] [2]).

Best,
Ryan

📝 Original message:
Hi Rene,

Thank you for the feedback! Very interesting to look back at the same
proposal from 2018, we clearly could have done a better job researching
past attempts. I have two main comments:

1) not trying to introduce a new repo, the linked lightning-rfc branch [1]
simply adds a new bLIPs folder in the existing repo (like you suggested as
an option in 2018)
2) major difference between 2018 and now is one of scale (which is a great
problem to have!). In 2018 the LN dev ecosystem was mostly ACINQ,
Blockstream, and Lightning Labs and the minimalist BOLTs process worked
well. At this point the broader ecosystem is significantly bigger than
those three teams combined, and it seems the process should adjust to
reflect the new environment.

The main goal of the suggested change is simply to provide a home for
emerging "best practices", especially those that require coordination
amongst multiple groups. I think LNURL provides a good example of a "best
practice" that has been spec'd out [2], is completely extra protocol so
probably doesn't belong as a BOLT, but carries tension with it for new
developers since it's been widely adopted yet not "officially supported".
What do you think about that?

Best,
Ryan

Hi all,

The recent thread around zero-conf channels [1] provides an opportunity to
discuss how the BOLT process handles features and best practices that arise
in the wild vs. originating within the process itself. Zero-conf channels
are one of many LN innovations on the app layer that have struggled to make
their way into the spec. John Carvalho and Bitrefill launched Turbo
channels in April 2019 [2], Breez posted their solution to the mailing list
for feedback in August 2020 [3], and we know at least ACINQ and Muun
(amongst others) have their own implementations. In an ideal world there
would be a descriptive design document that the app layer implementers had
collaborated on over the years that the spec group could then pick up and
merge into the BOLTs now that the feature is deemed spec-worthy.

Over the last couple of months, we have discussed the idea of adding a
BIP-style process (bLIPs? SPARKs? [4]) on top of the BOLTs with various
members of the community, and have received positive feedback from both app
layer and protocol devs. This would not affect the existing BOLT process at
all, but simply add a place for app layer best practices to be succinctly
described and organized, especially those that require coordination. These
features are being built outside of the BOLT process today anyways, so
ideally a bLIP process would bring them into the fold instead of leaving
them buried in old ML posts or not documented at all.

Some potential bLIP ideas that people have mentioned include: each lnurl
variant, on-the-fly channel opens, AMP, dynamic commitments, podcast
payment metadata, p2p messaging formats, new pathfinding heuristics, remote
node connection standards, etc.

If the community is interested in moving forward, we've started a branch
[5] describing such a process. It's based on BIP-0002, so not trying to
reinvent any wheels. It would be great to have developers from various
implementations and from the broader app layer ecosystem volunteer to be
listed as editors (basically the same role as in the BIPs).

Looking forward to hearing your thoughts!

Best,
Ryan
