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^(-? * k) + negl(?)

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

Where:
	?	? = entropy per DRAM timing measurement
	?	? = entropy per environment factor
	?	k, j = number of samples
	?	? = 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.

Greetings Punks,

moderator, sir/madame I understand that this may not fit in with the political criteria, I just thought
that it may interest you simply because of what it solves, and the fact that some of the time solving this problem was spent in this mailing list for the original solution or what led to it anyway with bitcoin. If it doesn't, and you do not forward it I completely understand.?

My work primarily has been revolving around scaling the technology in a pure trustless manner. I've also been working on post quantum stuff for bitcoin. 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".?

appreciate any in all feedback and it is a pleasure to make your acquaintances,
