Bitcoin Coders Send International Lightning Payment Over Ham Radio (2 minute read)
The Lightning Network is a protocol that enables fast transactions between participating Bitcoin nodes. Two developers, one in Toronto, Canada, and another in San Francisco, California, have successfully sent a bitcoin lightning payment over radio waves. While the transaction was just a demonstration of the concept, there could be practical uses for this method. For example, users can still complete transactions through this method even if a country censors parts of the internet (eg. if the Bitcoin network was blocked). Blockstream, a technology infrastructure startup, has satellites that can beam bitcoin to users around the world for similar reasons. The researchers admit that everything was coordinated before the radio signal was sent and that a real-world application would require expensive equipment.
I spent a week in a VR headset, here's what happened (17 minute video)
What would happen if you spent a week in Virtual Reality? Jak Wilmot sets out to answer that question by spending 168 hours inside a VR headset. He planned to eat, sleep, work, and play for a week all while inside VR, even when showering. The windows of his room were blacked out so that he couldn’t tell whether it was night or day, and he was only allowed 5 seconds at a time to switch headsets. The whole experience was live-streamed, showing his daily life. He could exercise in one environment, then switch to an office that overlooked a sunset in another. He could explore the world of Skyrim, and then experience what it was like to be blind in a simulation after. In the end, he concluded that virtual reality is whatever you want it to be, with its many possibilities, even though a week may be a little too much.
