Just caught wind of Jack Dorsey making some serious moves with Block's Bitcoin infrastructure. The company's pushing hard on the idea that Bitcoin should actually function as money, not just sit in a vault as a store of value. Worth paying attention to what they're rolling out.

Bitkey is their new hardware wallet, and it's got an interesting design choice - the touchscreen lets you verify and approve transactions right on the device itself. Most wallets split this between different hardware, which creates friction. They're keeping everything on one device with a 2-of-3 multisig model, ditching seed phrases entirely and adding inheritance planning. Privacy-focused too. Preorders are live.

On the Cash App side, they've upgraded Bitcoin handling pretty significantly. Automatic conversion on peer-to-peer payments means incoming transfers can instantly become Bitcoin. They launched Bitcoin Back rewards offering 5% in Bitcoin on Square merchant purchases through the end of the year - capped at $30 monthly per user though. Withdrawal limits jumped to $10k daily and $25k weekly, and if you're buying over $2k, they removed fees and spreads entirely. Direct deposit in Bitcoin is now available with zero fees.

What's interesting is the Proof of Reserves system they announced. It covers three different Bitcoin pools - Block's own treasury, Cash App customer holdings, and Square merchant holdings. Using on-chain signatures means users can independently verify everything. This transparency angle matters because custody trust is still a major issue across crypto.

Jack Dorsey's clearly positioning Block as a serious Bitcoin infrastructure player. Whether this actually drives Bitcoin adoption as a medium of exchange or just strengthens their custody offering remains to be seen, but the product direction is coherent. The removal of friction points like fees and seed phrases suggests they're thinking about real usability, not just marketing.
