I. Even with the most robust security technology and encryption, there is no complete trustlessness.

II$.$ The strongest consensus protocols harmful behaviour by certain fractions of participants or intermediaries well short of $100\%($as measured by their computing power, stake$-$holding, or individuation and counting$)$ can compromise the integrity of transactions or information flows between participants and thereby on balance harm the participants.

III. The historically recent breakthroughs of computer science can reduce vulnerabilities, often dramatically so$,$ but they are far from eliminating all kinds of vulnerabilities to the harmful behaviour of any potential attacker.

IV$.$ Although some cryptographic protocols do guarantee certain specific data relationships with astronomically high probability against opponents with astronomically high computing power, they do not provide complete guarantees when accounting for all possible behaviours of all participants.
