We’re thrilled to share that Hunter Beast (Hunter Beast), author of BIP-360 to upgrade Bitcoin’s quantum security, has joined the Anduro team! Hunter’s proposal aims to mitigate quantum security risks to Bitcoin by introducing a Pay-to-Quantum-Resistant-Hash (P2QRH) address type

We're thrilled to champion BIP360 for Quantum Resistant address types in Bitcoin at The Space this year! TAPROOT ADDRESSES ARE NOT QUANTUM SECURE - we're committed to fixing with Anduro senior protocol engineer Hunter Beast ⚡️ Anyone in Denver on 2/26 welcome to stop by!

I've always been a believer that there are only 2 real ways Bitcoin "dies". Something replaces it and makes it irrelevant, or its cryptography becomes hackable. Last year we had an emphasis on Taproot, this year I'm thinking TABConf - tickets on sale Oct 13-16, 2025, Atlanta has a focus on quantum resistance ideas.

Anduro lead architect + MARA Director of Engineering absolutely crushing at the Bitcoin Renaissance conference in Denver. Bitcoin scaling solutions must include payments to L1 miners for sustainability of the network as the subsidy declines. Merge Mining is a great solution ✨

If you're worried that nonmonetary use of block space will compromise the integrity of Bitcoin as money, then you're worried that financial sovereignty may not be the most valuable use case for the system and you're worried it can't compete for scarce block space. Maybe you

As Bitcoin stands today, a quantum attacker with access to P2PK keys could spend the ~1.7M BTC in those addresses within hours. ⌛️With Hourglass? 8 months. This isn't about lighting coins on fire and hoping for the best. As Shinobi puts it: "It's about addressing the
