A vault for the things only a person owns.
Fort Knox was built in 1936. It still works — for gold. The 21st century has produced a different kind of value, and no vault for it. AION is the missing vault.
What no existing vault holds
A bank protects money. A safe deposit box protects deeds. Svalbard protects seeds. None of them protect what is irreplaceable to one person: a crypto recovery phrase, a parent’s real voice, a witness’s evidence, a sealed letter that should open in 2125.
Today these things live on a phone, in a drawer, in a head that will one day stop. There is no inheritance. There is no Fort Knox for the soul of one human being.
Three moves, recombined
Math splits the secret.Shamir’s Secret Sharing breaks the encryption key into seven shards. Any four reassemble it. No single shard reveals anything.
Geography hides the shards. The seven shards live in seven sovereign nations, mixed across legal regimes, continents, and cloud providers. No one country has leverage.
Time defends the lock. A sequential hash-chain time-lock binds the unsealing to wall-clock work. Adding parallel attackers does not shorten it.
Each move is well-known. Combining all three under a zero-knowledge architecture — where the company that runs AION can prove it cannot read the vault — is what is new.
Every required ingredient just arrived
AION was impossible to build before about 2023. Production-grade Shamir libraries, zero-knowledge proofs in shipping consumer products, DNA storage from Microsoft and Twist, synthetic quartz from Project Silica, lunar archives launched on real rockets, and AI voice cloning at consumer prices — all of these matured inside a four-year window. Nobody has assembled them.
The single sentence under everything
People will pay any price to be remembered. They just need a system worth trusting.
Every other line in the Codex Aionis follows from that.
