Why the Bitcoin blockchain?
The Bitcoin blockchain is often associated with speculation. Yet what we use is its register: the most resilient digital infrastructure in the world, decentralized and owned by no one.
It has nothing to do with the famous cryptocurrency! We record your file's fingerprint in the Bitcoin blockchain to prove a date. You pay in your usual currency, a fixed amount.
Anchoring in the Bitcoin blockchain is available in the Premium plan.
We use infrastructure, not a currency
A blockchain is, above all, a shared register that no one can alter alone. The Bitcoin blockchain is the oldest and most solid of them all. For DfinA Vault, it acts as a public ledger that records, at a given date, the existence of a 64-character fingerprint. Nothing more. No token changes hands, no volatility concerns you.
The qualities that make it solid proof
Stated without exaggeration, because rigor inspires confidence.
Decentralized, ownerless
No company, no state controls it. No one, not even us, can rewrite a date or put pressure on the register.
The most resilient in the world
It is the network that concentrates the greatest computing power, running continuously since 2009.
Immutable
Anchored in the Bitcoin blockchain, your document's fingerprint benefits from the permanence of the most proven public register in the world. Its existence is dated irrevocably, and any later modification, however infinitesimal, can be demonstrated objectively.
Verifiable without us
The proof relies on open standards. Anyone can verify it with public tools, in full autonomy.
Durable
Your proof does not depend on DfinA Vault's survival. As long as the Bitcoin blockchain exists, and you keep your file, it remains verifiable.
Discreet
Only an anonymous fingerprint is recorded. It reveals neither your file, nor its content, nor your identity.
What this guarantees you
You obtain technical proof that a fingerprint existed at a precise moment, engraved in a register no one controls, while keeping your file with you.
The price is fixed, in your usual currency, and payment goes through Paddle, one of the world's best-known players for managing payments, subscriptions and international taxes.
Today, the Bitcoin blockchain is the most secure in the world. Like all current cryptography, it is not, when the day comes, immune to the quantum threat. But it is also the blockchain that concentrates the most at stake and the most talent dedicated to the durability of its code, and that several states are progressively adopting as a strategic store of value. It is therefore a safe bet that it will be among the first to become quantum-resistant.
Anchoring proves the existence and date of a fingerprint. It does not establish ownership, legality, or authenticity of the content. See what we don't do.
