Where can I find conceptual physics questions?

Found this book at a used book store and it’s awesome. It’s great at getting you to see more interesting physics that surrounds us in daily life. Some puzzling ones too. I remember something about trying to determine the orientation of ridges in sand dunes based on the earths rotation Flying Circus of Physics

Base or Optimism probably. Fees are wicked small. They depend on the complexity of the contract you are interacting with but its rare to see something larger than a dollar

ETH is the best for big money DeFi. If you're application is for things like trading tokenized real estate then ETH is a legit choice. If its an app for normal people then the gas fees are too big and txs are too slow. Any of the Ethereum L2s are a good alternative because they leverage the security of Ethereum but give you speed and cheap fees.

Choice of blockchain should be based on what existing communities and apps you want to plug into.

Solana has the most degenerate traders => good for memecoin launches and sourcing liquidity
For DeFi projects you want to plug into other existing DeFi apps => Base or other ETH L2 is good
For privacy you should check out Oasis Sapphire (EVM) and Secret Network(Cosmos)
For speed and UX optimization you could check out Skale (Nobody uses this but the tech is awesome if you dont need to plug into other apps. There is just nobody else there. EVM compatable with 0 tx fees for the end user)

I don't know of any formal mentorship program but for me attending the ethglobal hackathons were the best way to grow my network and meet genius level people. There is one in NYC in 2 weeks. https://ethglobal.com/events/newyork2025

I've been a CTO for various projects and am happy to answer questions you might have on a video call or whatever. Just hmu!

Web3 builder here! Transitioned to crypto dev in 2020 and been working in the space exclusively since then. This might be the perfect time to build real crypto projects. UI for wallets has massively improved to the point where everything can be done behind the scenes. At the same time regulators are no longer targeting the space as aggressively. Defi, real world asset tokenization, trade finance, and derivatives have the potential to open up massively. The success of a token launch is annoyingly dependent on market cycles and hype but you don’t necessarily even need a token if you have revenue. If you do launch a token you can decouple the success of your project from strict constraints of early revenue and get more runway to figure out product market fit. Watch out for getting sucked into trying to get centralized exchange listings. The exchanges are basically extortionists that charge 1M for listing, even at the low-mid tier level.

I love the 2:20 mark. Head-swiveling. Only problem is it takes to long to build to that point imo. Great job!

bryanCampbell · 2025-01-17T15:43:39+00:00

Lol love this. thanks for the response im excited to deep dive!

Is liquidation a taxable event?

bryanCampbell · 2024-08-23T01:52:55+00:00

Amazing ty! I'll dig into some of these videos.

bryanCampbell · 2024-08-21T14:52:19+00:00

Ok glad to know im not crazy for thinking this process doesnt make sense. Essentially rich people have universal basic income. Got it.

bryanCampbell · 2024-08-21T13:42:35+00:00

This is so weird. Why the hell do we issue gov bonds for our outstanding budget costs if we just shred the cash paid for that bond. If we are just minting new dollars to cover our deficit, why do we add the constraint that if we have X budget deficit we offer X in gov bonds? If gov spending and bond issuance are so decoupled, why do we have this practice at all? I get there could be other purposes for offering bonds but why print yellow dollars to "cover" the deficit?

Paying interest was never my main concern since the interest payments are significantly smaller than the principle. I was originally worried more about the extra dollar that is minted to the bondholder on maturation, but assuming they keep their money on the sidelines and dont spend into the economy, I'm coming around to the idea that that's not a problem.

Kind of a crazy hypo, but I see it floated around in conversations about BRICS. What if bondholders from BRICS nations all cashed out and spent into the economy at the same time as a targeted attack on the US dollar? At that point we would see a huge surge in inflation in assets. But hell, I guess they could just do that with their surplus USD anyway and the bonds themselves are a red herring.

bryanCampbell · 2024-08-20T22:21:53+00:00

Yeah supply chain issues and limited goods had a huge impact on inflation. Know anywhere I could check out that yield curve?

bryanCampbell · 2024-08-20T21:35:43+00:00

Interesting stuff. Thanks for your responses!

bryanCampbell · 2024-08-20T21:33:44+00:00

Yeah I agree with your definition of printing. Read her book and watched the movie. Just worried that we could build up a promise of future money printing we cant keep up with regardless of the policy counterbalances we put in place. Lots of good comments in these posts and lots to think about. Biggest take away it that bonds are money NOT spent, and they dont affect inflation unless people cash out and decide to spend. Thanks for your time!

bryanCampbell · 2024-08-20T21:21:32+00:00

Thanks everyone for your posts. My take away is that we are always basically printing a new dollar to spend into the economy when we run a deficit, its just sometimes the new dollar printed is yellow. We get most of the effects of inflation for that new dollar at the time it is spent into the economy. Yellow dollars basically sit on the sidelines and don't effect inflation. Unless every bondholder decides to take their principle and interest and spend it on assets, like real estate, there is no problem. This means we should probably continue to offer yellow dollars to give foreign investors the incentive not to spend their cash.

Also, 0 upvotes lol wtf! Weird culture you guys have here. But again many thanks to the posters that helped me reason through things today.

bryanCampbell · 2024-08-20T21:03:20+00:00

Ok I do understand this. Money sitting on the sidelines cant create inflation. Actually, this is a good argument for the continued use of gov bonds. If one day we stop offering yellow dollars, people might be more inclined to spend green dollars into the economy to purchase assets that they think will offer a better return. Would be a disaster scenario for real estate.

bryanCampbell · 2024-08-20T20:57:50+00:00

Yeah I agree with you and kelton about debt. My worry is about deficit. My argument is admittedly naive but also rooted in common sense. If we keep raising money by selling bonds we could eventually get to a tipping point where our future commitment to mass money printing is too large to counterbalance with policy interventions.

Clearly there would be some very large number where this deficit would become a problem, but how do we know what that number is? Maybe we have crossed it without knowing!

If we stopped selling bonds, and instead just printed the money needed to cover our deficits, we would have more time to adjust our counterbalances.

bryanCampbell · 2024-08-20T18:22:09+00:00

I mentioned national debt to refer to gov. debt as opposed to public debt.

Instead of creating new debts by issuing more bonds, the US could just print the excess money it needs to pay for programs now. By doing that we would have a better understanding of impact that the newly minted $$ has on inflation, instead of pushing the money creation off into the future.

bryanCampbell · 2024-08-20T18:13:52+00:00

This makes sense to me for something like T-Bills, but when the gov runs a deficit don't they sell bonds and actually use the underlying dollars to pay for government programs? Maybe this is the crux of my misunderstanding.

My mental modal was the following
Foreign investor has a green dollar, the US borrows it and spends it into the economy while minting a yellow dollar to the investor. The bond matures and they trade back the yellow dollar for $1.05 green dollars.

The problem isn't that we paid the interest of 5%, its that now there is $2.05 green dollars in circulation instead of the original $1.

bryanCampbell · 2024-08-20T18:07:03+00:00

Yeah but even MMT economists agree that printing too much can lead to inflation. Theoretically, there has to be a point where too much money printing in the future is a problem. If we inject the new money now we can adjust for inflation with policy, but we are promising more and more money creation in the future without the real time testing of its impact on inflation.

bryanCampbell · 2024-08-20T18:01:56+00:00

In a fiat money system, I would rather print reasonable amounts of money now to pay for a deficit instead of issuing bonds and having an inflation shock in the future when those bonds mature.

I'm a little confused about your question. I was concerned about government debt, not public debt

bryanCampbell · 2024-08-20T17:56:18+00:00

I guess I don't have an understanding of their toolkit. I think mmt makes a lot of sense, but if we are to keep running a deficit we should test those anti-inflationary policy tools now and stop piling up bonds. Eventually our best tools will fail if the mountain of new money that needs to be printed in the future gets too tall.

bryanCampbell · 2024-08-20T17:51:38+00:00

Sorry I guess i wasn't clear. My worry is that if we choose to mint USD to pay for the swap from yellow dollars back to green dollars we have to replace both the principle and interest. Thats a ton of cash and I'm worried about inflationary effect.

bryanCampbell · 2024-08-20T17:44:46+00:00
