Very interesting. I'd seen this a few times and ignored it. Thought it was just another bullshit product released mid cycle. It wasn't until I saw this page and dug deeper into it. Ordered a couple. I like how the owner is in control of two or three keys. Unlike fireblocks, where they are in control of 2 of 3 key shards. Did Block manage to "grandma proof" key management? 🤔 thanks!
