The LogVault Ledger

Every post on this blog is cryptographically chained to the one before it. We can't silently edit. We can't rewrite history. This is our chain of truth.

Chain Verified · 3 Blocks · Unbroken
01

Immutable

Each post contains a hash of the previous. Editing breaks the chain.

02

Verifiable

Anyone can verify the hashes. The math doesn't lie.

03

Transparent

Corrections must be appended, not hidden. Full accountability.

Technical Details(click to expand)

Algorithm: SHA-256 hash chain

Chain Formula: chain_hash = SHA256(signature + prev_hash + "LogVault")

Content Hash: SHA-256 of raw MDX file

Storage: Supabase (PostgreSQL) with append-only constraints

This is the same technology we offer to our customers. We dogfood our own product.
