@Guerrilla_BTC ¿Te casas y no me ha llegado invitación? Menuda falta de respeto.

@nevernotrunout @allocinitxyz @2140_dev @ChaincodeLabs Great meeting you Scott! Glad you had a good time

[Scott Odell @nevernotrunout]

Amsterdam was incredible 💯💯
Recap👇

- Our team from @allocinitxyz joined Bitcoin Research Week, hosted by @2140_dev & @ChaincodeLabs who brought together some of the best researchers and devs tackling the hardest problems in Bitcoin. S/o to the organizers who made it possible 🙏@ClaraShik @sr_gi @actuallyCarlaKC and all their teammates involved.

- Bitcoin Research Day (BRD) After Hours hosted by @allocinitxyz & @btcplusplus where research conversations and ideas continued over plenty of bitterballen

- Bitcoin, Bouldering, & Brews with everyone from BRD was a personal favorite. I organized this bc of how impactful Bitcoin & climbing have been in my life for nearly a decade now — both fostering the deepest relationships over shared pursuits of truth & freedom in many unique ways. Bitcoin has played a massive role in my wife & I having opened our own climbing gym, aiming to bring people together & build community in a time when the world around us feels extremely broken. Thanks all for coming out incl those who came for beers while watching the rest of us solve blocks 🤜🔸🤛

- Bitcoin for Corporations @BitcoinForCorps was extremely high value; highly recommend watching the recording of “Securing Bitcoin: Privacy, Custody, and Risk” with @Rob1Ham @nemothenoone @coinjoined @stonychambers 💯💯💯

- Bitcoin Amsterdam @bitcoinconfams was one of the best conferences I’ve been to in years. The presos and panels were outstanding. I’m immensely thankful for these events bc they allow opportunities for in-person/irl conversations with some of the most committed people pushing Bitcoin forward. Got a chance to sip Heinekens with @stutxo + speak with legends @danheld @Breedlove22 that I owe big thanks to for their educational work I absorbed like a sponge some 7+ years ago when I quit tradfi to instead commit my energy to Bitcoin.

Just left Amsterdam on a redeye to Korea — find me at @btckoreaconf presenting on our efforts to bring Zcash-style privacy back to Bitcoin L1 using cryptography, not consensus changes.

Grateful for the chance to meet everyone in Amsterdam these past 2 weeks — let’s stay relentless and keep pushing Bitcoin forward 🤝

As an organizer, how do you measure the success of an event?

I think this does it for me.

[2140.dev @2140_dev]

Meet @Eunovo9 , the Bitcoin Core contributor driving Silent Payments implementation. 🐦

@actuallyCarlaKC @sadeeq_ismaela What a flex 😅

[Sergi Delgado ⚡ @sr_gi]

"Encabezamos la lista mundial de muertos en accidentes de tren de alta velocidad, así que en vez de aprender de otros acerca de como gestionar el sistema, vamos a darle la responsabilidad a una IA"

¿Que podría salir mal?

[2140.dev @2140_dev]

Meet Rob, our very first hire over a year ago! 🙋‍♂️
With him on the team, 2140 was officially up and running. 🏃‍♂️‍➡️

@lunaticoin - "Nos encanta lo que haces"
- "Te escribimos para proponerte una colaboración crypto/web3"

Es decir, que no tenéis ni idea de lo que hago 😅

@Kruwed @sadeeq_ismaela

[Sergi Delgado ⚡ @sr_gi]

@n1ckler @darosior @ChaincodeLabs Unfortunately no, recording for prize talks has always been on a best effort basis, and this year we didn't have the means.

[Sergi Delgado ⚡ @sr_gi]

It's a pleasure for me to be able to keep running this amazing event year after year...

...despite looking completely exhausted by the end of it 😅

[bitcoin++ Insider Edition @btcinsider__]

JUST IN: “Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities” announced as this year’s winner of @chaincode’s Bitcoin Research Prize 2026

The paper, produced largely by Google’s Quantum AI (@GoogleQuantumAI) group, provided new resource estimates for breaking the 256-bit Elliptic Curve Discrete Logarithm Problem, the core of modern blockchain cryptography.
