Bitcoin Adoption Is Going Mainstream | Max Guise

Max Guise from Block joins the show to break down one of the biggest leaps forward for Bitcoin self-custody: BitKey’s new privacy upgrade, why it matters, and how it removes one of the last major trade-offs between safety and privacy.

We get into how BitKey’s new chaincode-delegation system prevents Block from seeing balances or transactions, and why this BIP unlocks a new era for private, user-friendly multisig.

We also get into Square switching on Bitcoin payments across the US and why that’s a much bigger deal than most people realise - removing the friction of onboarding merchants and making Bitcoin everyday money. As well as the structural risk of mining centralisation, how relying on a handful of foreign ASIC manufacturers threatens Bitcoin’s long-term resilience, and how Proto’s approach is designed to spread hashpower, strengthen the network, and give miners real optionality for the first time in years.
