# Bitcoin Is Fast AF

It can already be used for pay-to-send e-mail. The send dialog is resizable and you can enter as long of a message as you like. It's sent directly when it connects. The recipient double-clicks on the transaction to see the full message. If someone famous is getting more e-mail than they can read, but would still like to have a way for fans to contact them, they could set up Bitcoin and give out the IP address on their website. "Send X bitcoins to my priority hotline at this IP and I'll read the message personally."

"It might make sense just to get some in case it catches on. If enough people think the same way, that becomes a self-fulfilling prophecy. Once it gets bootstrapped, there are so many applications if you could effortlessly pay a few cents to a website as easily as dropping coins in a vending machine."

"Forgot to add the good part about micropayments. While I don't think Bitcoin is practical for smaller micropayments right now, it will eventually be as storage and bandwidth costs continue to fall. If Bitcoin catches on on a big scale, it may already be the case by that time. Another way they can become more practical is if I implement client-only mode and the number of network nodes consolidates into a smaller number of professional server farms. Whatever size micropayments you need will eventually be practical. I think in 5 or 10 years, the bandwidth and storage will seem trivial."

I began writing about using the lightning network about 150,000 blocks ago because I got tired of hearing that bitcoin can't make more than 7 transactions a minute. That was true 565,000 blocks ago, but is no longer true since the inception of the lightning network. For example:

- *We* sent 4,187 bitcoin payments over an 8-hour period at Bitcoin 2025, a Guinness Book of World Record winning achievement.
- Nostr is the biggest bitcoin circular economy in the world.
- Shake N Steak, a U.S.-based Hamburger franchise, accepts bitcoin over the Lightning Network at all of its locations.
- We can pay our credit cards with fractions of bitcoin (sats).
- We can use bitcoin over the lightning network to pay AI agents to do vibe coding using tools like [Stacks](https://getstacks.dev/docs) and [Goose](https://github.com/block/goose).
- [Bitcoin Helped Secure An Election In A County In Georgia](https://www.simpleproof.com/case-studies).

I pay for [Protonmail with bitcoin on-chain](https://proton.me/).

I can also use this email to send it to other people who do the same. I've only done this once to test it out, but it works. This is not new. The time chain uses Hashcash (with a double SHA256 algorithm instead of SHA1) for its famous proof-of-work. [Hashcash](http://hashcash.org/) was originally intended to prevent spam. Now you can use bitcoin to do the same.

I ran the numbers. Our world record is an average of 8.72 bitcoin transactions per second. This is just in one place, but bitcoin is a global monetary network. Bitcoin over the lightning network makes it possible to send value at the speed of light, anywhere in the world.

We won a world record.
We are winning.
We use money that we know works better than gold.
