I have written a bit about our portfolio company Blackbird but in case you didn't read any of those posts, Blackbird is a loyalty and payment network for the hospitality sector. You earn Fly and you pay with Fly. The more you pay with Fly, the more Fly you earn. Pretty simple and pretty awesome. Blackbird is currently available in NYC, SF, and Charleston South Carolina. If you live in or visit these cities, you can download Blackbird here.

I was using the Blackbird app this week and took a look at the "Where to Blackbird" map in the app and saw this:

When you are building a network, density matters a lot. Whether it is a social network, a real world network (like Blackbird), or some other kind, the value of the network goes up massively as density increases.

Metcalf's Law says that the value of a telecommunications network is proportional to the square of the number of users on it. Whether that is exactly right or just directionally right, it is clear that network value is non-linear and that more is better. In a real world network, it is not just more, but more in the right places. Which is why density matters so much.

The Blackbird team launched the network in lower Manhattan and have been building it out in ever larger circles since launch. The result is a very dense network where they launched and increasing density in adjacent neighborhoods.

The wrong thing would have been to launch Blackbird globally all at once. Having one venue in NYC, one in Paris, one in Dubai, and one in Singapore would have been useless. But four on the same block in the Manhattan's West Village created initial utility for everyone on and around that block.

If you are building a network, you need to be intentional and strategic about where you launch it and how you grow it. More is better. But density is key. So get some density and go from there.

When I woke up on Friday, September 27th, the first thing I did was put on an out-of-office notification on my email. That felt so damn good. It meant that for the next twelve days, I was dialing work down to the bare minimum and going away with The Gotham Gal to recharge and refresh.

We spent five days/nights in Seoul and another five days/nights in Tokyo. It was the first time for us in Seoul and the third time in Tokyo (and more broadly Japan). We did no work meetings and largely spent time together just the two of us. We walked more than 150,000 steps, took dozens of subway rides, and saw lots of both cities. We shopped, ate, drank, and soaked up the people and the culture as much as we could.

We are not "hire a driver/guide" tourists. I appreciate that approach to travel and have done it a few times with friends who prefer to travel that way. But when the Gotham Gal and I travel by ourselves, we do a ton of research and then get on our walking shoes and throw ourselves at the city. I particularly like taking the subway because that is where you see the people going about their daily routines. It gives you a sense of the people and the culture.

We ate in the food markets, the lunch spots with people on their lunch break, and also in some of the best restaurants in Seoul and Tokyo. I had a full Japanese breakfast (see the photo above) every morning in Tokyo. There is nothing like a Japanese breakfast to start your day off right.

We really like to shop in Korea and Japan. Many of our favorite designers are from there and they are creative without impacting the comfort and wearability of the clothes. So we did a ton of shopping and came back with lots of great stuff to wear this fall and winter.

It's a long flight there and back. The time difference from NYC is thirteen hours so the jet lag is no joke. But it is a great trip, the people are amazing, and the culture is quite different from what we have in the west and very compelling to us.

We had a great time and hope to go back soon.

When you think of founders who have been massively successful in bringing new and novel technologies and companies to market, you don't normally think of a nomad who has been living out of a single backpack for over a decade. You don't think of someone who talks like a modern-day Peter Kropotkin. You don't think of someone who walks through life with a childlike wonder for bugs, plants, and animals.

But that is exactly who Vitalik Buterin is.

I had the pleasure of attending the premier of Vitalik: An Ethereum Story on Wednesday night at the Angelika Film Center in NYC.

This film is nominally about the Ethereum blockchain and developer ecosystem. But it is actually an opportunity to spend just under ninety minutes with Vitalik learning about him and how he lives, thinks, and how he became who he is.

I have been in and around the blockchain sector for almost fifteen years. I am a fan and a holder of Bitcoin. I am a fan and a holder of Solana. I am a fan and a holder of Ethereum. I am a fan and a holder of many other protocols, tokens, and communities. I am all in on all of this.

But I will say that Vitalik has a special place in my head and heart. He doesn't just talk a good game. He lives his beliefs and leads from there. He is a very special human. And this film does a great job of showcasing that.

This film was funded by an Ethereum crowdfund on Mirror.xyz and is now being streamed onchain at ethereumfilm.xyz. If you want to stream it, you go there, mint an NFT for $20, and can stream it on your computer or on your TV if you connect an HDMI cable or airplay to AppleTV. The proceeds of the NFT sales will go towards getting a distribution deal with a major streamer so that this film can reach the general public.

Here's a trailer if you want to try before you buy:

I think the general public needs to know about Vitalik. The narrative around crypto, blockchains, and web3 is mostly about speculation and scamming. Vitalik is the opposite of all of that and his story can help the mainstream understand this sector and the potential of it.

So if you want to meet a very special human being, take some time this weekend and stream Vitalik: An Ethereum story. I hope you enjoy it as much as I did.
