    Throughout history, stores of value earned trust by being useful first – land fed people, cattle worked fields, gold enabled trade. Bitcoin, worth over $2.2T, has value but little utility. BitcoinOS (BOS) changes that, making bitcoin programmable, productive, and connected to real economic activity. We’re excited to have led their $10M strategic raise, which was announced last week ahead. With $BOS now listed on major exchanges including Binance and Kraken a new chapter begins – one where bitcoin finally works for the world, not just waits.

    We’re excited to share that we’ve built a position in peaq, the infrastructure layer for machines, robots and connected devices. This investment reflects two of Greenfield’s core theses: first, that the Machine Economy – where autonomous robots, machines and devices act as economic agents – will become one of the defining drivers of blockchain adoption; and second, that the future of crypto infrastructure lies in purpose-built, application-specific blockchains rather than generalized, one-size-fits-all networks. Alongside the investment, Greenfield operates a validator through Greenfield Labs, further aligning our long-term commitment to the network’s growth.
