The next few days ppl will make the case for how crypto would have solved the Robinhood saga:
1. Permissionless access - no one can block ppl from trading on DEXes or limit what assets they can invest in (theoretically)
2. Blockchain as a real settlement network instead of DTCC
Where trades are settled on T+2
3. Transparency allows for real time reporting on holding & shorts would bridge information asymmetry
4. Intermediary fees for market makers/brokers/settlements
The truth is more nuanced & grey.
1. Permissionless is only on-chain. Most ppl/capital still trade on exchanges or OTC. Despite a spike in on-DEX trade (with Uniswap even surpassing Coinbase during the DEFi hype), most trades will stay off chain for a while because /
Ppl prefer the most efficient & private route. That might change when private DEXes on L2 reach critical mass & can be more efficient than exchanges. for now privacy & convenience win, especially with early adopters who are usually introduced to crypto on exchanges similar to RB
If we hold crypto exchanges to the same scrutiny RB has received over the last week over blocking users, outages, gamification, collateral calls, then its fair to say crypto exchanges have failed in similar ways.
Most of us in crypto are familiar with how exchanges fail just when everyone wants to trade, that exchange who decided to liquidate its clients’ holding over three weekend cuz it chose not to make its collateral call, etc.
Most exchanges are a gamification biz not a tech infra m
Robinhood, unlike crypto exchanges, had gotten its share of regulatory heat for these very issues & chose not to address the real core of its business- how the fuck does their brokerage offer cheaper/safer/resilient gateways into the financial infrastructure.
The other permissioned aspect is what kind of investor has access to what asset. There were some calls this week to limit retail’s access to options u see the veil of investment protections. The Trump admin did a lot of work lowering accreditation requirements so investors /
Won’t be crowded out of a stake in growth areas, just like they were in the aftermath of the Great Recession. Most of the value add in the economy over the last decade has been in tech (private securities) & finance m.
We like to say everything in crypto is permissionless,
But blockchains being censorless doesn’t mean everyone can access the same assets at the same time. Like any market even crypto markets run on information asymmetry, thats where capital is made. DeFi might mask a lot of that through communities, DAOs & transparency but it’s there
Gas prices, MEV, flash loans, front runners, MM - the game may be different but it’s the game of small fish & big sharks.
2. Settlement infrastructure- traditional finance has been looking into blockchains for years. Their goal was to use the tech as a real time settlement system that can replace the long settlements time, especially for derivatives where T+21 is sometimes used for instruments like
CDOs, CDS, etc. the DTCC has a whole unit working on merging blockchain & so far it hasn’t been proven that better. Why? It’s not the tech. Turns out that net settlement is an advantage to off set counterparts risk
How would that look like on a blockchain if one collateral call ended in instant liquidation? Look no further than Black Thursday. Maker held up as a collateral system for DeFi. Given there are no collateral calls on DeFi, vaults get liquidated & markets react fast & painfully
3. Transparency - blockchains are transparency machines, till they’re not. Right now the public ledger seeks with traders data, but linking that to useful legal data like we see in SEC reports isn’t as intuitive as “it’s on the blockchain”, analysis tools help but that’s hermetic
If we can’t link holdings to legal entities, then that transparency is arbitrary & that’s before DeFi tools move to layer 2 with privacy tools to obfuscate even that data.
4. Intermediaries- just like Robinhood hasn’t democratized finance, crypto hasn’t disintermediated any intermediaries , we just built new ones & let them race to aggregate services so they can call themselves Prime Brokers.
Took me a long time to realize that’s now a failure
Why? Because the infrastructure crypto is built on is designed so that the market infrastructure itself is decentralized thus anyone can own a stake in it & participate in its business even with aggregators or intermediaries
The other force crypto has pushed forward is the means to coordinate money together, just like the WSB did from Reddit threads. So that individuals can coalesce capital together, or give the whales a fight. Look at projects like flashbots, DAOs & Enzyme

You can’t applaud Israel’s vaccine success without understanding the nation’s healthcare is built around community based preventive care run by 4 competing non-profit HMOs.

It’s like Obamacare’s multi-tiered public options run by free market, probably as progressive as it gets
How do they compete? On service, perks, tech & convenience.
How fiercely? Well, Covid introduced a new vector - offer young ppl vaccines before they’re eligible according to the national criteria.
So HMOs w/an older demographic started campaigns incentivizing young ppl to switch
The other aspect of the huge advantage Israel has is digital health record.
Rabin’s gov, who reformed the health insurance in 93’, made it a point to digitize all medical records & secure them across HMOs according to strict MOH privacy guidelines, including cyber security

DeFi truism:
1. DeFi is a rerun of the 2008 asset backed finance bubble on speed. Predictable with self-gobbling mechanisms multiplying systematic risk via leverage in the system & composability
2. The bubble will be bigger than 17’, due to leverage & shorts
3. People will scam
4. Eventually the Cambrian explosion will implode on bag holders, but the winners have a leg up in regulated markets. Their DeFi financialization protocols will be battle tested in a way no sandbox can match
5. Security tokens will win demand from tegaukted DeFi before enterprise
*regulated DeFi before enterprise security token gain any significant market cap. No matter which consortia is behind it
6. Some DeFi projects will immigrate to CBDC networks it’s corporate chains, after they’ve gained enough capital

A lot of DeFi is a sequel to the 17’ ICO bubble, not because these projects are scammy. The criminals haven’t arrived yet, but because of 3 primary drivers in the crypto market:
- Post-ICO projects w/ deep crypto treasuries that manages to survive the bear markets w/real products
2. Eth killers with 9-figure foundations, VCs & ecosystem funds that have yet to launch & need to demonstrate PMF to maintain their token’s price. What better way than to attract/invest in some DeFi infrastructure
3. DeFi actually uses infrastructure products the ICOs funded
That’s a signal that money is coming in to this bubble in the middle of a low yield environment where everyone is already trading by memes for random returns

with genuine humility i bring u some comments on David Marcus's attempt at Libra-splaining to congress, any snark is pathos free & unitentional. the fault is on the Zuck
banking.senate.gov/imo/media/doc/…
Marcus is careful to describe Libra as a payment infrastructure, although no token has managed to this day to deliver a scalable solution that can be deployed to millions, the ambition of Libra is far greater than that, and we have no assurance that is even plausible 2/
Even if users only use Libra for payments (a theoretical) don't ignore the fact that Libra membership is a security token, earning their holders a share in the interest income of the reserves. it's income on FB's R&D costs no less.

Short thread on the app-ripple effect of the Apple privacy/identity announcement. Apple is in midst of transitioning into a service company, where the premium users' pay on hardware is akin to a fee. That tradeoff will tickle down to 3rd party apps who need to contend w/biz model
up till now users' looking to use/access apps were asked to sign up using an identity layer (FB/Google) or share their email. the biz model was a trade-off, users' data was not only shared with the app, but that identity provider (FB/Google) in the following ways: 2/
1. Sell in-app ads using the combined cross-referenced data from FB/Google, mostly on the FB/Google ad exchanges. Where the tech giants serve as the market infrastructure, the sellers (of attention real estate) & the buyer (for their own content)

Thread on Big 4 Blockchain strategy & some enterprise ZKP snarks, as someone who has been shilling ZKPs to enterprise from the get-go when big 4 so called partners were questioning why the f the should care 1/
coindesk.com/ey-nightfall-e…
The @EYIntlTax announcements is big news as an auditing firm becomes a tech stack player, not just a consultant & integrator.
@pbrody has been at the forefront of ZKPs & blockchain for awhile, and has made a huge bet with Nightfall on several fronts:
* open source + copyright waiver - a novelty for an auditing firm, might end up being a huge liability risk as @prestonbryne chimed in.
* SAP ERP modules (licensing, supply chain), where a singular process is represented as ZKP ERC721 token 3/
