@CoinbaseDev This history is definitely missing a mention to L402 developed by @lightning , @roasbeef and @positiveblue2 . Some credit where credit is due 🙏🏼

First, a little history:
HTTP 402 “Payment Required” has been a part of the internet’s blueprint for decades, but it was never used.
x402 turns this 402 status code into a real payment layer—letting any server request payment, and any client (human or agent) respond with digital dollars, i.e. stablecoins like USDC.
English
We are excited to introduce x402–a new open source payments protocol built on HTTP rails.
Let’s break it down:
English
@CoinbaseDev How does this fit with the L402 protocol developed by @lightning ? 🤔
English
x402 is fixing the internet’s first mistake.
Onchain payments are now easy and frictionless, opening new use cases for agentic commerce for API providers, context retrieval protocols, content creators, and more.

There are many companies using L402-based solutions today. @MichaelLevin highlights @fewsats, @sulusolutions, @openagents, and PlebAI (tag yourself! Twitter search is failing me) who are all building different solutions in the space 🫡

I shared the following note with the OpenAI team today.

@v0 Can access and pay for APIs with a single key using Sulu: sparkhub.sulu.sh

Thoughts? Whether agreeing or not, I think it's important to have these conversations.

@karpathy this is exactly what we are building for API monetization at Sulu.
Check us out 👉 sulu.sh
Would love to chat more about this.

I feel like a large amount of GDP is locked up because it is difficult for person A to very conveniently pay 5 cents to person B. Current high fixed costs per transaction force each of them to be of high enough amounts, which results in business models with purchase bundles, subscriptions, ad-based, etc., instead of simply pay-as-you-go. As an example, I'd like my computer to auto-pay 5 cents to the article/blog that I just read but I can't, and I think we're worse for it. In a capitalist system, transactions between entities are the gradient signal of the economy. Because our pipes don't support low magnitude terms in the sums, the gradients are not flowing properly through the system. I'm not familiar enough with payments to have an idea of specific solutions, but I expect we'd see a lot of positive 2nd / 3rd order effects if the gradients were allowed to flow properly, frictionlessly and with much higher resolution.

"A large amount of GDP is locked up because it is difficult for person A to very conveniently pay 5 cents to person B".
Spot on and this is what we are solving at @sulusolutions : pure realtime pay-as-you-go API monetization.
As @karpathy says, this is needed for AI now.

Signed distance functions (SDFs) are fundamental tools in graphics, vision, and physics simulation.
But how do you get a high-quality SDF from messy, real-world input? At #SIGGRAPH2024, we introduced a simple method for turning "broken" geometry into a well-behaved SDF. <🧵>

For 2300 years, we've been working with flawed definitions of math. We defined it as the science of numbers and shapes, or that of logical deduction, but none of these definitions make any sense and they obscure the true nature of math.

My most ambitious post ever: we've been *wrong* about math for 2300 years and I’m going to *fix this* in a single Twitter thread.

@openagents Deep market research. Countless hours spent here that could be automated.

Next big update we’re working on is long-lived agents that can take action in the background even if you close the browser window
Set and forget, check in when you want
These are good at coding but we’re looking for other ideas what they should do
DM us ideas for early access

🚨 Flow 2.0 Depreciation Incoming! (...and what's next)
Today we are announcing the depreciation of the Flow 2.0 LSP at @voltage_cloud . Starting September 1st, we will no longer issue new channels from our API. Channel closures will commence on November 1st. Anyone with a channel to the LSP (including ones in @MutinyWallet) should send out their funds and do a cooperative close at their earliest convenience.
We've made this tough decision with a lot of consideration and market research. It's challenging to run a well functioning LSP at scale and we are always considering our return on invested capital. Ultimately the inputs required for the LSP, which is engineering resources, infrastructure, and liquidity, were not producing adequate returns compared to other opportunities. Things like low usage, high start up costs (initial channel creation), and technical complexity were prohibitive for LSP growth. I, personally, don't see channel selling being a worthwhile, large business venture in the near term.
HOWEVER, we aren't just leaving the Lightning Network without solutions. We are working on a radically new system that will produce a far superior experience. We've gained years of insights into how people use Lightning and what matters most. We're shifting our Flow 2.0 resources to create the most advanced Lightning system in existence. We'll share more as we have it.👀
Given all the shake ups in the Lightning ecosystem this year, I'm sure there will be some FUD about "regulations" or "lightning is dead". None of this is true. This decision is specifically a product decision and one we are making to ensure we can handle the growth of the Bitcoin ecosystem now and in the future. We're bullish as ever and very excited about the coming months and years.
If you have any questions please email support@voltage.cloud. We'll be happy to help however we can during this transition. End of an era but start of a new one…. and the new one is going to be incredible.

🌐💸 In the late 1800s, sending money overseas could take longer than six weeks. By the 2000s, that time had dropped to just three days—a huge improvement, 21 times faster.
But here’s the real game-changer: with the Lightning Network, it can happen in less than three seconds🚀That’s not just faster—it’s 1.2 million times faster! 🤯 This incredible leap shows just how far we’ve come in the last 25 years🕰️✨

My TL;DR of database choices in 2024
- Pick Sqlite iff you don’t need the db to be accessed over network
- Pick Postgres otherwise
- Never pick NoSQL (and I did my PhD on NoSQL)
Also shout out to this awesome article for more depth 👇
