Why I Remain Optimistic About Crypto

I'm at home in Ghana right now. Just used crypto to buy a weekend at this resort.

I traded USDT on Binance P2P for mobile money and paid with that
(mobile money = emoney account on your phone number, eveyone here uses it).

"Kofi", I hear you ask, "why couldn't you have just transferred money to a Ghanaian bank account and paid with that? Why use crypto at all?"

Three reasons:

(1) The value of the Ghana Cedi is in freefall. Over the past year, the exchange rate has gone from 11GHS:$1 -> 15.5GHS:$1. I don't want to hold Cedis. I want to buy the exact amount I need at the moment that I want to spend it.

(2) To avoid holding Cedis, I could open a dollar account at a Ghanaian bank. The problem with this plan is that I don't trust Ghanaian banks. Our financial system has too many failings to summarize in a tweet. And there are horror stories of folk having their dollar account spending restricted right when they really needed it.

(3) On top of that, wiring money to a Ghanaian bank account from a foreign one takes days and the fees are high. So tradfi transfers aren't a good fit for my "buy small batches of Cedis when I want to spend" strategy

Because of these reasons, I act as my own bank when I'm home. I hold dollar stables in my crypto wallet. I swap those stables for mobile money as the need arises.

I don't get disillusioned because crypto solves a day-to-day problem for me: Securing my cash in a country where I don't trust the institutions.

That said, I understand why the CT crowd gets disillusioned. Most of you reading this are based in the West (US, Europe). When I'm in the West I don't spend crypto day-to-day the way I do at home. I just use my Western bank card like a normal person. Because I'm pretty sure my Western bank won't fuck me.

You're disillusioned about cryptos' usefulness because it genuinely isn't that useful to you right now 🤷. To make it useful you need to build new things, novel and exciting consumer apps.

Sadly, I think you'll understand what I mean soon. It feels like the world is hanging on a thread. The US is in a $34T debt crisis. Europe had a brief recession this year. There might come a day when you don't trust your institutions either. If that day comes, crypto will let you work around the system.Image

How has EIP-4844 impacted L2 costs?

1/ As the table below shows, most L2s experienced a 90%+ reduction in their L1 costs after adopting EIP-4844 blobs

L1 costs = Gas and Blob Fees for batch posting transactions + Gas Fees for proof verification transactionsImage
2/ Since their costs dropped by an order of magnitude, L2s could afford to reduce the gas fees they charged users.

As shown in the charts below, the cost of making common transactions like ETH transfers or Uniswap trades has dropped 90%+ on most L2s.

3/ I look forward to seeing all the new use cases that this low-fee environment enables!

For more insights into how EIP-4844 has transformed the L2 business model, and links to the code for all these charts, check out my blog post 👇

I often get asked the question, "What's happening onchain?"

The answer usually lies in incentives. Every new wave of onchain activity is driven by a new incentives playbook. For example 👇
[2020] Liquidity mining

- Compound, a lending protocol, kicked off the liquidity mining trend in June 2020 with a wildly successful token incentive program. Compound's TVL spikes from $100M to $600M in one week

- Every DeFi protocol under the sun copied this playbook and DeFi summer entered full swing.Image
[2021] Joint Liquidity Mining

In early 2021, the Polygon Foundation launched joint liquidity mining programs with popular DeFi protocols.

First was Aave. Polygon gave $40M worth of MATIC to lenders and borrowers on Polygon Aave. Users bridged to use Polygon Aave to earn these incentives -> Polygon Aave's TVL grew rapidly.

Polygon repeated this playbook with other protocols like Curve and Sushiswap. Polygon’s TVL jumped from ~$100M to high billions within two months.

The playbook was replicated by a host of other chains like Avalanche (see Avalanche rush) and this drove the alt-L1 rotation in 2021.Image

Learning crypto data science changed my life and was 100% free.

If you're looking for a change (I was a transport planner), start coding 1 hour a night. More on weekends.

Pick a simple @DuneAnalytics project. Learn just enough to build it. Pick a bigger project. Repeat.
It took me 3 years to get to my current level of crypto data proficiency (preceded by 3 years of writing coding in other fields). Here are some free resources you can use to get there 10X faster 👇
1. SQL and Blockchain data

Go to Headmaster Andrew's twitter account (@andrewhong5297) 🧙‍♂️✨

Click the link in his bio.

You'll find intro guides for Ethereum, Solana, and Bitcoin Dune data analysis.

Pick one and get it done.

Here is what rollups spent on posting data to Ethereum in November:

1. Arbitrum - $4.4M
2. Linea - $3.7M
3. Optimism - $2.508M
4. zkSync Era - $2.506M
5. Scroll - $1.43M
6. Base - $1.34M
7. Polygon zkEVM - $678k
8. Starknet - $500k
9. Zora - $211k
10. Aevo - $109k
11. Orderly - $101.2k
12. zkSync Lite - $101k
13. Public Goods Network - $95k
14. Mode - $31k
15. Lyra - $17kImage
You can query insights like this using the Rollup Economics Spell on @DuneAnalytics.

Huge thanks to Archwizard @LehmannLorenz for adding Scroll and Linea to the dataset last week! 🧙‍♂️✨

It's been 5 months since I started that Spell. Feels really exciting to see more wizards building it up 🥹

Here's an example of how to use the Spell 👇

The rollups I have revenue data for made more than enough to cover their costs.

Their gas fee systems are designed to cover the L1 cost + add a premium.

In November, revenue from gas fees was:

Arbitrum - $5.94M
zkSync Era - $5.48M
Optimism - $3.09M
Base - $1.6M

How to become a DeFi frontend engineer (starting from scratch):
Step 0: Learn basic JavaScript and HTML from a free resource of your choice (CodeAcademy, w3schools, freecodecamp .etc)

For JavaScript, if you understand variables, functions, if statements, and while loops then you're fine.
Step 1: Work through the reading and exercises in the 'Get Started' section of the React documentation (Quick start, Tic-tac-toe, Thinking in React .etc)

React is the most popular library for frontend engineering
