Bitshala BOSS Summit Jaipur is live 🔴

First up, the drop: this year's BOSS Summit tee, designed by our very own @_paperpsych 🙌

“Crafting for generations to come.”

We chose these words because the work we do today should outlive us.

Bitcoin is built by people who care about what comes next. Every line of code, every contribution, every idea shared gives the next generation something to build on.

And that's what we want BOSS Summit to be all about. Learning from each other, building together, and leaving something behind for those who come after us.

A little reminder on a T-shirt of why we're here in the first place.

For the next 5 days, we'll be sharing updates from the sessions, along with presentation links, so you can follow along even if you're not here with us.

Onwards 🚀

Every Taproot signature comes down to one equation:

s = k + e·x

So why can't anyone forge it? 🔐

Tonight we finish our signatures deep dive with @sha512rma:

→ ECDSA vs. Schnorr
→ Multisig + a critical attack vector
→ The Forking Lemma: forging Schnorr = solving the DLP

That’s a wrap on Building Bitcoin in Rust (BR) Season 1! 🎓🦀

Over 10 weeks, our builders worked through the Braiins curriculum, progressing from Rust fundamentals like ownership and traits to async networking and Bitcoin node design.

The goal was to move beyond learning Rust and start applying it to Bitcoin development. Watching participants turn that learning into production-style projects has been a highlight of this cohort.

Congratulations to everyone who put in the work and earned their Proof-of-Work certificates. ⚡️

The next step in Bitcoin development starts with builders like these. 🟠

Don't keep your sats idle, run a Router with Portal. https://t.co/qHgjoE4Qpg

“Every company is an API company now, whether they want to be or not.”

The next big shift is making APIs work for agents, not just developers.

@restless_hq is building toward that future with live API context, self-improving docs, and errors that tell agents how to fix themselves.

Less babysitting. More agents getting things done.

[Bitshala @bitshala_org]

Every Bitcoin swap needs liquidity. What if you could provide it yourself and earn sats when others use it?

Meet Portal, the hands-on way to explore OpenSwap v0.2.3.

• Run a Router and earn swap fees
• Create a Bitcoin wallet and make a swap
• Explore routes, fees, and fidelity bonds

Our latest article walks you through setup, funding, and your first swap.

Hmm 🤟

[Summer of Bitcoin @summerofbitcoin]

summer of bitcoin alumni are on a generational run 🧡

Ansh & Leonardo secured long-term @btrustteam support.

now @hey_yuvicc (SoB '24/'25) & @sliv3r__ (SoB '25) have @OpenSats grants!

4 alumni funded in 3 weeks. we're building the next generation of bitcoin open-source devs!

[Bitshala @bitshala_org]

We were full for BOSS Summit. But quite a few of you kept reaching out asking if there was still a way to join.

So we’ve made room for 10 more people to attend the BOSS sessions in Jaipur.

₹2,499 gets you access to all 3 days of sessions + lunch and evening snacks.

That’s all the space we can open up. If you wanted to be there, now’s the time.

➡️ Get your spot: https://t.co/iIwIAWYFwJ✨

If you're a developer, work in open source, contribute to Bitcoin, or want to start doing so, you'll find your people here.

*Session Pass DOES NOT include stay or the Bitmela pass.

- Transaction introspection, covenants, and scripting limits
- Vaults, timelocks, and better self-custody
- Building miners, SeedSigners and steel seed plates in India
- Fuzz testing and contributing to Bitcoin infrastructure
- Protocol ossification and the future of Bitcoin development
