DRAM-Based Dual-Binding Random Walk (DBRW)

TL;DR:
	•	Hash-chain-driven random walks over DRAM → unique timing fingerprint
	•	Extracts environment-bound features (path, inode, namespaces)
	•	Combines both via a one-way binding hash:
H_bind = H(DRAM_walk_hash || env_params)
	•	Cannot be replayed, migrated, or spoofed
	•	Fully offline, quantum-safe, no enclave dependency

Key Security Bounds:

Cross-Device Forgery:
P[success] <= 2^(-α * k) + negl(λ)

Same-Device Partition Attack:
P[success] <= 2^(-β * j) + negl(λ)

Where:
	•	α = entropy per DRAM timing measurement
	•	β = entropy per environment factor
	•	k, j = number of samples
	•	λ = security parameter

No TPM. No TEE. No bullshit. Just physics + math.

Verification time: under 50ms
False acceptance rate: ~10^-10
No network dependency

Let me know if you want the full paper.

Stealth addresses introduced by Peter Todd, deterministic random walks as zero knowledge proofs, and a lot of experimenting with state channels, both bilateral and unilateral, as my concept of self validating state transitions, and balance variance embedded led to what I came up with in this paper, which is the "Decentralized State Machine".
