DFINITY Foundation — Maintains core protocol and tooling. NNS governs upgrades, but DFINITY remains the primary contributor
AMD SEV-SNP — Hardware-level confidential computing requires specific AMD processors. No alternative vendor currently supported
Node Hardware Specs — Standardized requirements limit the pool of eligible node providers and hardware vendors
These are structural dependencies, not corporate control points — no single entity can halt the network or access user data. But they are real constraints worth acknowledging.
5 Known Failure Modes
Boundary Node Outages — Mitigated by redundancy, but regional disruptions have occurred
Subnet Halts — Have happened (e.g., fiduciary subnet 2023). Consensus stalls until nodes recover
NNS Proposal Bugs — Governance risk: a bad proposal could pass and affect the network
Canister Cycle Exhaustion — Developer responsibility. If cycles run out, canister stops responding
Replica Software Bugs — Mitigated by subnet replication, but bugs in consensus code affect all replicas
∞ Cryptographic Guarantees
Chain-Key Cryptography — Single public key verifies all responses from any subnet
Certified Variables — Responses include cryptographic proof of correctness
Threshold Signatures — No single node holds a complete signing key
BFT Consensus — Tolerates up to 1/3 malicious nodes per subnet
