Embracing Bitcoin's DIY ethos, I've crafted a guide for engraving BIP39 seed phrases as minimalistic glyphs on beer cans—offering a cheap and secure storage alternative (with extra obfuscation) compared to paper wallets: bitcan.world

(03:05) - What is its impact on everyday Bitcoin users? (06:21) - How does the mempool work today? (11:52) - Current mempool heuristics and issues (16:37) - Censorship resistance and economic demand (22:56) - Practical implications for exchanges & miners (26:12) - How does cluster mempool work? (29:29) - Transaction clusters & mempool dynamics (37:27) - Should mempools align across the node network? (43:47) - What about other implementations of Bitcoin? (48:17) - Other interesting areas for bitcoin development (52:11) - Closing thoughts

Vinteum BDL Mentor Spotlight: Matthew Zipkin ⚡ "It's a simulation of the Bitcoin Core development process but in a hackathon environment." Matthew tells us about the "quorumeum" challenge he ran for students in the @vinteum_org and @libdesatoshi programs during BDL week. In the interview he shares what the role of a Bitcoin maintainer actually looks like, and how changes get merged into Bitcoin Core. Matthew works on educational initiatives at @ChaincodeLabs, and is impressed by what he sees from the Latin American Bitcoin communities.

generally we hand write content over at Insider Edition, but this retrospective from the Warnet over at @btcplusplus exploits edition last month is a little uhhh different Hilary Kai a bot participated in Warnet: here’s her write up of the event 📝

Day 3 at @btcplusplus Floripa — full focus. We’ve got two B4OS teams in the hackathon finals. Huge effort from the crew. Now getting ready for the Lightning Warnet kickoff: a round-robin judging session led by @niftynei from @base58school and Matthew Zipkin (pinheadmz) from @ChaincodeLabs . These games help surface failure modes and potential network weaknesses before they reach mainnet — so we can learn faster and build more resilient Bitcoin systems. 🇲🇽(ES) Día 3 en @btcplusplus Floripa '26: foco total. Tenemos dos equipos de B4OS en la final del hackathon. Tremendo trabajo del equipo. Ahora nos preparamos para el kickoff del Lightning Warnet: una sesión round-robin de evaluación liderada por @niftynei y Matthew Zipkin (pinheadmz). Estos ejercicios ayudan a identificar modos de falla y posibles debilidades de la red antes de que lleguen a mainnet: para aprender más rápido y construir sistemas Bitcoin más resilientes. #B4OS #BitcoinDev #Security #BitcoinSecurity #FOSS #Hackathon #btcplusplus

How about this for a BitDevs location? 80+ people. Potentially the largest BitDevs we’ve ever had in Brazil. Floripa Bitdevs BTC++ edition, hosted by the Floripa crew with São Paulo and Barcelona Bitdevs joining as guest hosts. cc @btcplusplus + @libdesatoshi

Bitcoin Core v31 will include: - improvements to transacting privately - protections against eclipse attacks - further improvements to the modularization of its consensus engine library - better interfacing for Stratum v2 mining - improved block template creation, tx eviction, and mempool behavior via cluster mempool - other performance improvements and bugfixes
