LOGOS BLOCKCHAIN — DATA AVAILABILITY LAYER

DA Calculators

Interactive parametric calculators and visualizations for the Logos Blockchain DA protocol. Open directly in any modern browser.

SAMPLING ANALYSIS
DA Sampling Calculator
Models data availability sampling as a binary hypothesis test. Sweep parameter spaces and observe how sampling configuration affects Type I/II error bounds, grey zone width, wasted slots, and blockchain security horizon.
Hypergeometric α / β errors Grey zone Δ Wasted slots T₁/₂ security Block builder
ADVERSARIAL ANALYSIS
Adversary Attack Surface Calculator
Analyses the capabilities of an adversary controlling a fraction p_d of DA nodes. Models Attack A (liveness) and Attack B (safety) and shows how each protocol parameter shapes adversarial effectiveness.
Attack A (Type II) Attack B (Type I) p_d regimes τ / t / R effect P_fail^eff = p_d^t
VISUALIZATION
DA Sampling Animation
Step-by-step visualization of the full DA sampling pipeline: blob encoding, dispersal, multi-validator sampling, querying, and chain fork outcome. Supports up to N=2048 subnetworks and m=256 validators. Includes Honest, Attack A, and Attack B modes with Cryptarchia fork visualization.
