Free/Open Source dev. Coding Bitcoin Lightning #CLN. Disclosure: https://t.co/FKKy1mfalr
Joined September 2015
Don't know if I've done this right, but I'm trying to detail the minutiae of the Great Script Restoration development at npub179e9tp4yqtqx4myp35283fz64gxuzmr6n3yxnktux5pnd5t03eps0elz4s.

If #Bitcoin confuses you, it's important to remember that we're trying to change *accepted social norms*. That's weird, slow and confusing. In my Linux days we were dealing with "that's not how you construct software", Bitcoin is "that's not how you construct money". 1/7.

Speculating on Satoshis identity is not just a way increase someone's risk of violent theft attempts: it also pointlessly disrespects his clear desire for privacy. Be classy: keep your fantasies to yourself.

Repricing #bitcoin in sats is sensible, overdue and a hard challenge. I'm impressed we're taking it on. Remember: there will only ever be 2100 trillion sats!.

The most damage to #bitcoin development was done by altcoins and their successors. The noise and scam feedback loop made the entire space anathema to most FOSS devs, our natural allies. That's why I have zero tolerance for alts.

Finally, Lightning Spec v1.0 tagged! Special thanks to all at @acinq_co @lightning @Blockstream who pulled together, and of course @tdryja and @jcp for starting the snowball. There's no pause though, we're accelerating with 1.1!.

Of course, then you will never make the next generation understand how radical the now Normal Thing was, now their perceptions have shifted. I'm just astonished that I get to do this *twice*. I'm really not even that clever, I'm just amazingly lucky. 7/7.

You may disagree with how #bitcoin was designed, but you should understand it. Genuine apologies if this is discomforting news, but this needs to be part of our base knowledge. Longread.

So, that's my plan: just keep making things better wherever I can, again. Today, that's lightning and BOLT specs. And others take it, do Great Things, and sometimes they'll know who I am and sometimes they won't. But step by step, their successes normalize it. 5/7.

I, too, wish it had happened faster. But I chose to keep helping, and progress is being made. I genuinely hope you're as happy with your choices, Jeff.
It's not amazing, it's embarrassing. The #bitcoin payment solution that was purported to be ready by year 2019 is, in year 2022, barely squeaking over the "payment went through on the first attempt" milestone. 🤦♀️

@JackMallers @roasbeef @Snyke @WhalePanda Good call, @JackMallers. Just analyzed block 600,000 to 601,000, and there are exactly *zero* to-local penalty spends. So either lnd saved confused-dude's ass here despite his best efforts, or he's just making it all up.

I am hiring for our extraordinary #clightning team at Blockstream! We work and learn together: Lightning offers something new to the world and I can't see it all. We need more different viewpoints to help steer our efforts. Plus it's fun! Consider?.

When I read the original LN paper, but nobody committed to actually *build it* and Greg Maxwell said I should try, I knew what success looked like. When @lightning @acinq_co and I met in Milan to hammer out the first spec, we all knew. We just didn't know the probability.

Lightning is an idea and a protocol. It's also three exceptional dedicated teams building something larger than any of us, with more coming and all having *so much* fun. @lightning @acinq_co @Blockstream
There are three implementations that make up the #LightningNetwork today. ⚡️. #Eclair written in Scala by @acinq_co #lnd written in Go by @Lightning Labs #clightning written in C by @Blockstream

And it only really works if the developer keep incrementally improving things (and there is so much to explore and improve!). We have something here, and it will spread, but it will be gradual because it's unconventional. I expect it to take a generation. 6/7.

Any "analysis" of FTX is worthless if it doesn't start from "SBF was a fraud from the beginning, with a billionaire origin story about Korean crypto arbitrage which never added up". (Kudos to Greg Maxwell who pointed this out before FTX collapsed).

There are three types of spam problem in #Bitcoin #LightningNetwork; let's call them "local", "slow" and "fast". local spam is someone sending or requesting too much data: that's a Simple Matter of Code, with ratelimiting etc. Let's talk about the other two:.

A reasonable summary of the OP_CTV proposal. My take: I find the CTV benefits weak, and want general covenants a-la OP_TX or Elements-style opcodes. Meanwhile SIGHASH_ANYPREVOUT is even simpler and has immediate, concrete benefits, and won't be later deprecated. #Eltoo FTW.
In the coming days/weeks there are going to be a bunch of people trying to twist what I say to try and project a world view onto me that I don't actually hold. So here is a thread that states my position on CTV and its activation procedure. I will update if/when my view shifts.

Lightning Labs has claimed ownership of the Lightning network in many ways: I've been reluctant to call them out in public. But the lightning network and community deserves better. They didn't implement it first, they didn't implement it best. Their community is great though!.

As far as I can tell, we developers just kept developing the technology. Others took it, made companies or products, sure. But we just, y'know, kept polishing for decades, because it was fun, rewarding and useful. Weird became normal, even mundane. 4/7.

For Linux I had read and sympathized with RMS's GNU Free Software vision at University, but it took Linux to actually show me it actually *worked better*. But I was the "weird Linux guy" for a long time, then inside a "weird Linux bubble". 2/7.

So @alexbosworth doesn't understand the Lightning Spec process. I thought Lightning Labs had been so quiet in the last two years because (1) @roasbeef is the only one there who's allowed to do spec stuff (2) profitability lead them to pivot to proprietary centralized offerings.

What happened in the 25 years between "Free Software exists if you can't afford real software" and "all important software is Open Source"? Between the social norm of Digicash as a proprietary patented solution and Bitcoin as anonymous FOSS? 3/7.

My technique is simple: try to be the smartest person in the room. If that fails, try to be the wisest. If that fails, try to be the kindest. If that fails, shut up and hope they don't kick you out of the room!.
It's not the 1st time that I observed the humbleness of @rusty_twit & the respect he shows towards other developers!. Rusty's contributions for Linux & Lightning are well known. But this show of character goes beyond coding skills. One day I shall pass this on to newer developers

I still advocate that major players in the Bitcoin ecosystem should have a 1-2% stake in mining. If only for their own insurance.
We began our Bitcoin mining operations in 2017 due to widespread concern that mining was becoming centralized. At the time it appeared parties involved in ASIC manufacture, hosting and pool operations were becoming a centralizing force holding back Bitcoin from its full potential.

Turns out they've decided they can leverage network dominance into protocol control, and the spec process isn't "real". Mea culpa: I have spent far too much time on the spec process, and not enough on implementation polishing and marketing. That changes today.

I wrote the Australian Capital Territory voting and counting system (Open Source of course). I work full time on "blockchain tech", and could not agree more. And yeah, this is a hill I am prepared to die on; unlike many hypetrains this idiocy can affect my democratic rights.
@dav917 Let me make something clear, no sarcasm at all: Blockchain has no place in civil elections. Period. Anyone who thinks it does is unqualified to be working in election technology or to be making recommendations to policymakers. Is that clear? I hope it was clear.

#lightning gossip needs updating for Taproot; I've been thinking do we tweak or re-engineer?. Currently, you send channel_announcement, specifying the channel UTXO, supplying the 2 keys in the 2of2, the node ids, and signatures for each of them. (This needs update for Taproot).

Today's bolt12 #Bitcoin lightning offers feature is my fav: recurrence! Vendors love to sign you up for recurring CC payments so they are in control. But the core *idea* is useful, and in the Bitcoin world there are no pull payments, just push: your wallet is in control.
