Where public information is available, Jack accounts for 90.5% of total OpenSats donations, 14.2% of Brink donations, between himself and Jay-Z, 100% of donations thus far to Btrust, and has also donated to the MIT DCI Bitcoin security Initiative, but the amount was undisclosed and we believe to be a relatively small proportion. Additionally, Jack is the cofounder and CEO of Block, which is the parent company of Spiral.
