Consensus isn't a document. It's a decision miners make under pressure, in real time. 13 blocks behind on an invalid fork. Caught up. Reorged back to valid. This is what the job looks like on a quiet Saturday

A Slack badge just reminded me that yesterday was my 13th work anniversary at @f2pool. It brought back memories of those days when I met @bitfish in early 2013 and we set off on our Bitcoin and crypto adventure together. On the high-speed train to work, I was using LRUSD to buy bitcoins in bulk across several international dealers, then selling them to novices on Taobao, converting the proceeds back into LRUSD, and repeating the cycle. On good days, I could make over a thousand dollars across multiple round trips. Thanks to the strong market in those first few months, I managed to save up $100,000, which finally gave me the confidence to take the leap. Many years later, looking around, @bitfish is still one of the best entrepreneurial partners one could ever hope to find. The only regret is that I was so focused on taking photos of the trains and train stations those days that I barely captured any other pictures for what we were actually doing in Bitcoin and crypto at the time.

Someone once paid a $515,000 fee to send $2,000 in Bitcoin For a few days in September 2023 nobody knew who it was Then it turned out to be Paxos, the company behind PayPal's stablecoin A single buggy transfer turned $2 in fees into $515,000 while the usual fee was around 61 cents F2Pool mined the block and could have legally kept every coin but they gave it all back 5 days later

Railway is not just a means of transport. It is a culture. Japan has it. China has it. India has it. Russia has it. The United States once had it, but it has long been forgotten. Despite Europe having plenty of railways, it doesn’t have a well-established railway culture. Without a culture, it will never have a soul.

This photo is possible because Artemis II is the only crewed lunar mission launched just before a full moon. All Apollo missions were launched 10–13 days before a full moon, as they were timed so the lunar module would land shortly after the lunar sunrise.

We make a flyby of the Moon in a free-return trajectory before committing to landing on it. Now with the “Gateway to Mars” in place, should we make a similar flyby of Mars before committing to a landing there, too?

When people talk about a once-in-a-lifetime trip, they often don’t realize that they may truly never return there. Many journeys that seem grand at the time eventually become ordinary parts of our lives. But even the little restaurant next to your home might, after some ordinary day, become a place you never visit again. Will space be once in a lifetime? I think not. But I really don’t know whether I will ever set foot on Bouvet again. I think Bouvet Island will very likely remain my true once-in-a-lifetime trip.
