Vinteum fellow @IsaqueFranklin0 presented "Limbs, carries and reduction: field elements in libsecp256k1" at @tabconf today.
The talk built a mental model of how libsecp256k1 represents 256-bit numbers as 5x52 field elements. Want to know more about it? The written deep dive behind it covers the same ground:

We’re excited to announce the Q3 2026 Btrust developer grant recipients. 🚀
Ten Bitcoin open-source developers are receiving support: five starter grant recipients and five long-term open-source cohort members.
This quarter also marks an important first: Btrust developer grants are going directly to developers outside Africa. Through our recent expansion of long-term grants across the Global Majority, we’re now supporting developers in Brazil 🇧🇷 and India 🇮🇳.
Their work, alongside that of recipients in Nigeria 🇳🇬 and Kenya 🇰🇪, spans @bitcoincoreorg, mining ⛏️ infrastructure, Lightning⚡, wallet libraries, and privacy-preserving payments.
Meet the recipients and learn about their work:
