Farcaster is a playground for crypto experiments—I find myself discovering and trying something new every week. This is a log of my experiences.
Digits is a fun little math game by Daksh. You get rapid-fire arithmetic questions like “What’s 58 ÷ 7?” and have 60 seconds to get as many right as you can.

It’s simple, fast, and brings out your inner competitive nerd. There is a leaderboard. So, you can check out the top Maths folks of farcaster. For me, it was mostly a reminder of how much slower and older I've gotten.
The app’s delightfully designed. Give it a spin and give Daksh a follow. He’s building cool stuff.

Loring is a man of interesting interests. Last week he put an open challenge for Lizard Spock Rock Paper Scissors. We played this on a really cool web app that uses MPC Framework. MPC enables multiple people to compute something without revealing the values they hold.
I took help of our ever helpful chatGPT to come up with a simple explanation of how it works and this is what it shared.
Let multiple people compute something together, without revealing their individual inputs to each other.
There are a few core techniques, but here’s a basic idea using “secret sharing.”
Let’s say 3 people want to know their average salary,
but no one wants to reveal their salary.Each person breaks their salary into random-looking pieces and gives one piece to each of the other two.
For example, Alice’s salary is 100k:
She splits it into: 30k to Bob, 40k to Carol, keeps 30k.
Each person does this.
Well, I ended up besting Loring 2:1 and he was kind enough to sponsor an ice cream for me.
I love when people dogfood their own products.
Linda’s been doing just that and exploring the dev side of building on the Farcaster mini app ecosystem. She’s been on a bit of a spree, releasing a bunch of fun experiments. The latest: a Pokemon Mini App that looks at your casts and tells you which Pokemon you are.

I’ll admit, I barely know anything about Pokemon but apparently I’m a Machamp.
Give it a spin. And if you’re building on Farcaster, don’t hesitate to reach out to Linda—she’s been super helpful.
Last week we wrapped up the third round of The Clankline.
Incentives, especially monetary ones, can blur the real signal around whether people actually care about what you’re building. So it was encouraging to see that, even without any rewards running, a solid number of folks still logged in and shared their ranks.
We’ve shipped a bunch of improvements since the V1 launch three weeks ago. You can now check your Clanker portfolio, track how you're doing within your friend group, and see a live scan and feed of the top Clanker tokens.

Now each person adds the pieces they received.
Because the math works out, they get a total sum —
but they never saw anyone’s actual salary.
Together they divide the total sum by 3.
Everyone knows the average, but no one learned the others’ salaries.
Secret Sharing – like the example above.
Homomorphic Encryption – do math while data is encrypted.
Garbled Circuits – a fancier way to build a digital black box for computations.
Oblivious Transfer – one party learns something, but the sender doesn’t know what was learned.

Glad you enjoyed our games of Rock Paper Scissors Lizard Spock! It was created by the PSA group at the Ethereum Foundation.
Gm bossman 😁, hope you slept well 😴, happy Sunday to you

every week, I write a short post on the top 3 highlights of mine from farcaster. This week 🔻 digits by @dakshk.eth : learning how good or bad you are in maths. 🦎 🖖 🪨 📄 ✂ with @loringharkness Learning I'm Machamp via Pokemon mini app by @linda and sunny days on @theclankline https://paragraph.com/@rch/farcaster-fridays-my-top-3-highlights-from-this-week-8 https://pokecast.vercel.app/ https://app.playdigits.fun/24 https://mpc.pse.dev/apps/lizard-spock
thanks for the mention, and 24 is NOT a bad score haha
Discover the latest in crypto experimentation on Farcaster from @rch! The latest blog post covers several experiments, including the exciting math game Digits by Daksh, an engaging challenge with Lizard Spock Rock Paper Scissors employing MPC techniques, and inevitability interesting reflections on a fun Pokémon Mini App by Linda. Each endeavor offers a glimpse into the innovative developments within the Farcaster ecosystem. Don't miss the exploration of the Clankline platform and its ongoing improvements!
