256 Foundation is a US 501(c)(3) public charity (EIN 99-1662333) dedicated to making Bitcoin mining free and open-source. The organization has received grants from the Human Rights Foundation's Bitcoin Development Fund and has an official partnership with Block's Proto group to support open-source Bitcoin mining initiatives.

As a nonprofit focused on grant-making and education rather than custody or financial services, 256 Foundation does not hold user funds, making traditional trust metrics like proof of reserves or insurance inapplicable. Their work centers on funding open-source projects where all hardware designs, firmware, and software are publicly auditable. Grant recipients are evaluated through an application and interview process, with grants paid in either bitcoin or fiat according to recipient preference.
