Model 2 — Tradeoff Table¶
Candidate comparison from the Model 2 optimizer. The recommended_safe layout is the only one that survives every protected scenario; candidates that show a higher raw net value do so by failing required protected failures and are therefore not feasible.
| Candidate | Status | Validators | AWS_A | AWS_B | AWS_C | GCP_A | GCP_B | HOME | GCP roles | Protected failed | Net CTN/yr |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 3 AWS nodes with 15 validators each | fails_some_protected | 45 | 15 | 15 | 15 | 0 | 0 | 0 | off, off | 10 | 98.36 |
| optimized validator count on 3 AWS nodes only | fails_some_protected | 63 | 21 | 21 | 21 | 0 | 0 | 0 | off, off | 10 | 145.16 |
| 3 AWS nodes + home VC | fails_some_protected | 42 | 12 | 12 | 12 | 0 | 0 | 6 | off, off | 16 | 81.44 |
| 3 AWS nodes + 2 GCP VC-only nodes | fails_some_protected | 40 | 8 | 8 | 8 | 8 | 8 | 0 | vc_only, vc_only | 16 | 76.09 |

How to read this¶
cheaper_riskier(45 validators, 98.36 CTN/yr) shows the highest raw net value but fails 10 protected scenarios — it is AWS-only, with no provider-independent beacon path. Higher number, not feasible.- GCP VC-only expansion adds validators but preserves AWS beacon dependency, so it fails AWS-beacon-degradation cases (16 protected failures). Only GCP combined nodes remove that dependency.
recommended_safeis the first row that reaches 0 protected failures, and the maximum-reward and optimizer-discovered rows converge on the same 48-validator layout.
