Replacing checking accounts with crypto accounts by 2030

Is a good adoption goal for developed countries

The path we're betting on rn is:

1. Pick up scraps. Focus on what's underserved by traditional processors, i.e. payments hit with high flat fees / bad corridors / big chargeback rates / recurrent censorship. Probably 1% of consumer payments

2. Experiment on scraps. Try to induce new financial behavior with tiny 1%

3. Find lightning-in-bottle with scraps. Some crazy interaction catches and crypto claims the other 99%
I've always wondered who these middlemen are who we're so excited to fade

Turns out there are a lot of em, and we’re pretty good at fading em

Example, what happens when you swipe a credit card:

Accurate when we were small. Now similar vibe to “internet is for communication”

Crypto's already delivered a handful of differentiated user experiences. Many more to come WOOO

Crazy question raised by traitor tracing:

How much money would it take to betray your friend?

Traitor tracing is the best mitigation we have for server side privacy breaches (the core of the MPC v TEE discussion)

MPC == "server that stores your data" is split between 10 people, users are hoping they don't get together to peek

TEE == "server that stores your data" is a fancy box that's hard to break in to, users are hoping Google doesn't peek

Unclear which one's better. Both are bad for the same reason: peeking historically hasn't been punishable

Not good. Crypto rests on bad actors getting punished. It's why staking is so important

How to make peeking punishable? For TEEs, there's no active proposal. For MPC, there is, and it's called traitor tracing.

Traitor tracing == a way for a someone to prove their friend peeked via math

i.e. If me and my buddy peek together. We're both traitors. My buddy can turn on me and slash me to oblivion

The only valid reason to make a new L1:

a) You want the influence that only an L1 has
b) You want to use this influence to create a new asset category

A GREAT reason

Should be used instead of technical reasons that are closer to sleight of hand than anything:

1. Doing something new?
>> That's an execution layer improvement- what L2s are for

2. Faster finality?
>> Finality for validator set becomes preconf for decentralized sequencer set, w/ no deterioration in reorg resistance

3. Higher throughput?
>> Probably won't outpace danksharding roadmap with real tx demand

4. Better decentralization?
>> Lmao will the bottleneck really be Ethereum's decentralization
"Wtf, we already scrapped TEEs in 2019, how can people forget" - common complaint floating around now

Isn't accurate. Current discourse isn't "forgetting" and pushing the same approach again.

The landscape has completely changed since 2019:
- [1] Alternative risks to not deploying enclaves have increased. Eg: risk of casino winning
- [2] Complementary technologies that patch up enclave shortcomings have been productionized. Eg: zkVMs
- [3] Clearer now that exotic forms of cryptography won't get the job done anytime soon. Eg: attribute-based encryption
- [4] New virtualization-based enclave designs available. Eg: TDX

This is technology. Trying old ideas again under new conditions is the backbone of our innovation cycle.

If "we've tried that already" was our industry's motto, we wouldn't have Tesla, Oculus, or even Bitcoin.
You think crypto infra is useless? Wrong

Here's the strongest case for why these projects can be just as principled as Amazon.
TEEs are picking up steam! Tricks we use in our system to get the "best" security model we can:

[1] Scary to depend on a small set of unstaked nodes to verify a computation. Alleviate via multiple confirmation rules like TEE attest -> TEE attest and ZKP -> TEE attest and ZKP and ...

[2] Scary to depend on cloud providers with kill switches. Alleviate by spreading TEE networks across different centers (AWS, GCP, Azure) and imposing a lower bound % for independent SGX nodes.

[3] Scary to depend on hardware manufacturers to not backdoor. Alleviate by secret sharing across nodes with different chips, though this only works if decryption conditions don't require the secrets themselves.

Main driver of everyday crypto adoption in the US won't be payments, it'll be payouts

Crypto has a clear pitch for non US citizens: access to USD

What about for US citizens? They already have native USD and the rails to spend it

So, not spending. What about earning?

Not all meme coins are ponzis

DOGE / WIF / DEGEN aren't

Diff? They aren't zero sum. They meaningfully expand the market for cultural artifacts

Lot of launchpads today optimized for PnD

Genuine opportunity in creating a launchpad that's optimized for making the next DOGE
CEXs take "owning the user relationship" to the next level

At least in the traditional world I don't need to go through Bank of America to use Youtube

CB is already steamrolling the rollup part of the stack, now might with wallets too

Underrated reason for lack of consumer builders:

Embarrassing to tell your mom / girlfriend / mentor / deli guy what you do

I milk the fact that "cryptography" sounds fancy to regular people

Can't spin @friendtech.eth, even though it was the most interesting experiment of 2023
why do we call them "intents" lol

just say cross-chain swaps
Have been using this framework when thinking about consumer:

Hit crypto native dapps let users buy something that goes up

Breakout apps that we've seen have either innovated along 1) how to buy, or 2) what to buy

Has helped me get in the greenfield mindset for both:

Privacy is all or nothing (at the technical level).

You can't have one component here or there be private. The entire value chain needs to be.

Any kink in the chain demolishes privacy guarantees.

Why? Quick example. Suppose you had a DEGEN position on Base worth $1M.

*L2s == rapidly shrinking pie*

Playbook used to be: launch L2 w/ centralized sequencer, don't launch token, upgrade multiple times in search of PMF

Now will likely see: launch L1 w/ Proof of Authority, don't launch token, upgrade multiple times in search of PMF

Same thing

How to avoid accidentally 𝐥𝐚𝐮𝐧𝐝𝐞𝐫𝐢𝐧𝐠 𝐦𝐨𝐧𝐞𝐲

Sounds silly, but surprisingly easy to do if you're not vigilant.

One small tweak in a seemingly unrelated module and suddenly kim jong is salivating.

To prevent this, we now ask two questions prior to shipping:

Run the EVM in an MPC.

Would be a significant contribution if someone pulled this off.

Why? We're increasingly seeing a reliance on TEEs for shielding smart contract info.

Uncomfortable security model. EVM in an MPC alleviates these concerns.

Favorite two liner from Research Day yesterday:

Chris Goes: “The world gave crypto a finite amount of goodwill. We’re consuming it at an alarming rate.”

Shoutout to all the goodwill production factories (RWAs). You’ll have reinforcements soon WOO!
"We have reached feature parity with web2" always prompts an adverse reaction bc of the knee jerk nOo stOP BEing sKeuOMORPHic thINK nATive DOn't cOmParE.

I appreciate the intent but it's wrong.

Parity when inheriting the properties of blockchains is a big deal.
The acacia plant is diabolical.

1. Needs ants for defense.
2. Produces nectar to incentivize ants to come.
3. An enzyme in the nectar changes the ant's digestive system so it can no longer eat other food.

Now that's real vendor lock-in.

Who built this? They open for roles?
Revisiting the Proof of Solvency work from 2022 right now- doesn't seem correct to spend more time there.

Instead of starting with a CEX and giving it DEX-like guarantees here and there, likely better to start from a DEX and figure out how to make it compete with a CEX.

Generally a fan of biometrics-backed authentication.

Although they do create some weird incentives for targeted attacks.

I'd rather be able to hand over a hardware key than be forced to hand over an eyeball lol.
Not a believer of "too much money is a bad thing" for startups.

P(squandering | team) isn't affected by raise amount when founder discipline + advisors remain constant.

I know a team with a $50mm chest w/ $250k monthly burn. As disciplined and focused as ever.
Partially homomorphic encryption is ridiculously under-utilized.

It opens up a massive swath of use cases via strong concurrency and minimal data leakage.

And you can get it with just 256 lines of circom.

I remember all these posts after the last crash saying "lesson learned, we should stop looking at TVL and start looking at organic tx vol".

These posts went viral- there was consensus. A hard fork of evaluation metrics.

Turns out that fork was actually Ethereum Classic. Whoops.

simple mechanisms are often how technologies reach adoption (think of the AMM as the starting point for dexes)

{membership proof + arbitrary sig} circuit (i.e. sapir-ecdsa https://github.com/personaelabs/sapir )is our AMM
