Quotes that support claims

Next, the insider attack test: How much damage could a corrupt insider cause? Lastly, the trusted computing base test: How much code must be trusted for security to hold?

In his typical jeans and relaxed dark T-shirt uniform, Buterin laid out practical “tests” that he said every crypto project should pass. These include 1) the walk-away test. If the company behind an application disappears, do users keep their assets? And 2) the insider attack test: How much damage can rogue insiders or compromised front-ends cause? And 3) whether it has a trusted computing base: How many lines of code must be trusted to protect users’ funds or data?
