This is insulting, as I remember very well reviewing some hard parts of recent ongoing changes such as some API changes for watchtower integration or the state machine for collaborative transaction construction. Adopting a pure quantitative measurement of the review contributions is short-sighted and I think your position forgets with any mature open-source project review of the hard and sensitive part of the codebase is the bottleneck. We're working on a decentralized bitcoin open-source project, there is no benevolent dictator for life with the legitimacy to qualify who is a major or "spokesperson" contributor, and who is not. I understand this is your job to work full-time on LDK, though I don't think there is any contractual provision in your work contract requesting to play the BDLF. If you have a different viewpoint or other professional information to communicate to the community, thanks. > In 2022 and 2023 you: > * landed a PR removing yourself from the security-reporting list (#2323, no idea why you're trying > to speak for the project when you removed yourself!) > * fixed one bug in the anchors aggregation stuff before it was released (#1841, thanks!) > * made some constants public (#1839) > * increase a constant (#1532) > * added a trivial double-check of user code (#1531) If I remember very well my anchor output patchset was ready to land in the second-half of 2020, though at that time we didn't have enough qualified review bandwidth and I spent a hell of a lot of time reviewing other people's contributions through 2020/2021 to move the project nearer from production-readiness. That lesson about the anchor output patchset, i.e coming with meaningful code diff to do _interesting_ things and solve hard problems as quite rendered me frivolous to show up with big diff, and waste my coding time (when I can make advance on solving LN-related problems in Bitcoin Core). I think very recently I proposed changes to advance mempool monitoring and custom script support, though here again it sounds to me we're still lacking qualified eyes to bring informed technical opinions on the areas necessitating a lot of context. About #2323, the reason of removing myself from the security-reporting list is related to weak and non-consensual code of conduct you introduced last year which brings severe vulnerabilities to LDK process w.r.t social attacks by external actors and risks of long-term shitshow a la Rust governance, which I raised immediately on the code of conduct PR. I think you never answered me neither publicly or privately on the lack of robustness of this code of conduct if we're targeted by psyops from NK-hacking groups (Sadly, real-world thing in the cryptocurrency world). I have no doubt we'll be able to rebuild consensus on our security-handling / project community process in the future, with calm and patience. > You've also, to my knowledge, never joined the public bi-weekly LDK development calls, don't join > the lightning spec meeting, and don't engage in the public discord discussions where development > decisions are made. Again this is insulting to use the word "never" as I was the original host of the LDK development meetings on Slack and I think I took the initiative to launch the LDK review club last year. All those meetings / communication spaces have public logs to parse interesting to look on and in fine development decisions are made in a continuous fashion, where the review and testing process on the repository being the main factor. And I'm pretty active reviewing things on the lightning spec side at least as much as you. > This implies you absolutely don't have a deep understanding of all the things happening in the > project, which makes you poorly suited to speak on behalf of the project.

If you like to judge my "deep understanding" of LDK codebase, you're free to throw a ldk-sample with the latest v0.0.116 release , throw your money on it on few channels, send me the node public key and then you'll see after a while if the funds are still there, otherwise this is cheap talk and just the subjective appreciation of your mind. In reality, I'm still weekly reviewing and hacking on Bitcoin Core's sensitive parts related to Lightning, and I don't necessarily have the time to attend *all* the meetings. As a LDK maintainer you should be happy to have contributors still actively working on Bitcoin Core in the state of current cross-layer issues, this is not a leisure that all the other LN implementations can afford! > While I know you feel like lightning at large isn't a protocol which takes security seriously, I > think you're pretty far off base here.

This is not a personal sentiment, though an objectivable engineering facts that Lightning as a protocol / network is weak, that I did prove few times in the past for different class of vulnerabilities and that I don't think you'll argue Lightning is fundamentally weak until package relay / nversion 3 is deployed and integrated in lightning implementations, and this will take another couple of years at best. I hear you man on the ton ship of features to make lightning and usable, I think I gave a talk on the liquidity toolchain back in 2019 and the long road ahead, and I think I'm currently reviewing dual-funding at the spec-level and in LDK, which is clearly a future people building real-things on Lightning wish. Come on, I've reviewed almost all of the hard parts of LDK, I know it's hard though security-first, more and more end-users have their skin in the game. > If you followed LDK (and other lightning) development more closely, I think you'd have a greater > appreciation for these things :). I think I've been talking in real-life to actual LDK users more recently than you. If you would listen to Lightning users in an open-minded fashion, not from your ivory tower of a lightning protocol dev, you'll know how many people are complaining on the poor usability of the LDK interface, and this is quite the reason ldk-node was launched, no ? > I'm really unsure what you mean here "open-source ethical rules" - is it your opinion that you > should speak for a project you don't really follow closely just because you think the people who do > work on it a lot aren't doing a good enough job in your opinion? That seems incredibly strange to me. Yes when you're an active contributor to the said project, that you're spending nights actually reviewing and testing fixes like the ones we landed for the fake channel DoS vector and you're quite spending a hell of lof times landing and reviewing other robustness things in the Lightning ecosystem, you're kinda legitimate to say people do not do a good enough job. This is my current appreciation with 5y of experience than the current LDK maintenance team adopting a "move fast and break things" attitude w.r.t landing new features and code changes. I don't know if this is motivated by some kind of competition for the lowest common technical denominator with other implementations and fear of losing usage market share). Though yes, I think the project is taking significant technical debt, especially w.r.t security, safety, performance and code modularity dimensions. I think you're as knowledgeable as myself on the history of the Internet, I think you're very familiar with the security weakness of the major Internet protocols like BGP / SMTP and DNS which have somehow led to the current centralization of mainstream Internet service/usage. In the current state Lightning is still weak, it will take another 10 years at the current engineering pace to fix all the major flaws. If we hit TheDAO-like massive ecosystem hacks leading Lightning users to take refuge behind centralized "wallet gardens", all the hard work on liquidity management or routing or state management is quite useless. If this is happening, I don't think all the senior Lightning developers and open-source project manager we'll be able to say we didn't see this coming. I think Matt Morehouse's security report is actually an independent underpinning of the meager state of Lightning robustness. This is where I'm not sure the Lightning community is doing its best in terms of open-source ethics and safeguard of end-users interests. So I'll keep "speaking" for the LDK project whether you're pleased or not, when I have got my hands dirty on the subject and the current maintenance team is not doing the job. And all that said, this is okay to have conflicts in an open-source project and this is somehow positive to grow in terms of culture, communications or technical philosophy. Thanks for the hard work you've been doing on LDK for years, though if you aim for more social recognition you're free to go to work on another open-source project. Minding the deep respect I have for your sense of dedication and technical skills, _I don't need you to hack or understand the complex LDK codebase_. If you wish to improve LDK communications, feel free to take accountability to organize the 1st LDKDev community event (in the image of CoreDev) in person (maybe SF or LA in the second half of 2024?). I think someone proposed that idea under "Bitcoin Builder Event" and I think I still have the publicly shared gdoc from 2021 though this idea has stayed cheap communication so far. In the meantime, there are only 144 blocks in a day (on average) and I have package relay and mempool to review in Bitcoin Core to improve Lightning for all, further discussions won't be constructive and I won't reply further.
