How a Web2 Company Uses Crypto to Power Open Data APIs

Thank you to Art, Fred & Jake for reviewing and providing feedback on this post! Question: Does your software use APIs? Where do you find the endpoints? How do you get the specifications? How do you ensure quality? šŸ¤” tl;dr There is a big opportunity to build the ā€œGoogle home pageā€ for finding and accessing open data sources and services. An open marketplace of APIs does not exist today. API Discovery and RPC Quality are the two core primitives necessary to enable this. ...

Nā‚‚O: Revisiting the best Nuclear Investment Vehicle

tl;dr If you’re invested in URA because of Uranium, consider diversifying that position into other ETFs or fully moving it over to NUKZ to broaden your nuclear exposure. This is not financial advice. Special thanks to ChatGPT, Google, Reddit and Claude for helping me research, prepare, write and edit this post. Last May I wrote about why I’m allocating a large portion of my portfolio to Uranium with a bullish perspective on the nuclear sector at large. ...

My Top `X` 2024 Recommendations

Last year was the first time I published a ā€œTop X Recommendationsā€ blog post to close out the year. I heard from about half a dozen people who found at least one recommendation interesting or useful—which means there were probably even more who never mentioned it but still got something out of the list. So, I figured I’d do it again! In the very likely scenario that you either don’t have the time, interest, or attention span to read this whole thing, just scroll to the very bottom because the last one is by far my favorite. ...

Move Fast & Document Things

I’m going to share a small secret: a perfect solution to software documentation does not exist. It’s hard to generalize what ā€œgood documentationā€ entails. It depends on the team, the product, the timing, and a million other things. Have you found PMF or are you iterating? Are you a small tight-knit team or are you scaling? Is your team remote, in-office or hybrid? Is open source and external collaboration a key component of your value proposition? I’ll stop here before it gets boring… ...

Reflections of working in Crypto

tl;dr People come for the long-term vision but stay for the short-term gains. Success is measured only by how good your NGU algorithm is: Number Go Up. A vaporware product with good marketing can go the distance until it memes into existence. There is a lot of cynicism and politics behind open doors. Intelligent and authentic leaders are critical in upkeeping community optimism. It’s still early.

My Top `X` 2023 Recommendations

Whenever I get really excited about something, I tend to tell all my friends about it. This could range from a book or movie to an activity or something I bought. I can find a good handful of people who can attest that sometimes it gets excessive. Over the past couple of years, I’ve been slowly turning olshansky.info into the one place to find and search through my resources, but there is still a lot of work ahead, and I expect it to be a lifelong endeavour. ...

Probability Distributions 101

ā€œYou’ll never use most of the things you learn in College.ā€ - Olshansky circa 2014 There was a time when I thought that most of what I learnt in College was pointless since it didn’t apply to my day-to-day work. However, as time passes, I increasingly reflect on how fortunate I was to be exposed to so many concepts across various fields. Most importantly, it teaches you to think, learn and work, but I’ll save the details for another post. ...

KZG via ECG

*This is a fun open idea for Ethereum’s KZG Ceremony: using your Apple Watch’s ECG as a source of entropy to participate in Ethereum’s KZG ceremony. I got a response when I first proposed it to the Ethereum foundation in December. Still, it does have some open-ended problems and requires a non-trivial amount of implementation effort. If you find it interesting and have the time to implement it, I’d love to see it come to fruition! * ...
