      Can someone from @BitGo pls chime in and describe how "setPolicyRule" calls are protected?https://twitter.com/el33th4xor/status/761492444303265792 …

      It's also unclear to me how "Set Policy Rule" is authorized. Docs look like they reuse the same key.

      Spoke to @bendavenport from BitGo & based on his description, am convinced that setPolicyRule is not fundamentally insecure in the BitGo API

      even if diff API could have been used BitGo still blind signing, why no human oversight for $60m?

      so @BitGo automated all the things and signing 120k BTC w/out human oversight is good opsec?

      Last I heard, @BitGo facilitates over $1B in txns per month. I don't see how injecting human middlemen can scale.
