Paradigm offers anti-quantum protection for Satoshi's $84 billion Bitcoin

The $84 billion in Bitcoin attributed to Satoshi Nakamoto could well be threatened by quantum computers. To this end, Paradigm offers a revolutionary solution: PACTs, a method for securing these funds without revealing their owner. A major breakthrough for the crypto ecosystem.

Here is Paradigm's method to protect Satoshi's $84 billion in Bitcoin

A few days after a researcher broke a crypto key using a consumer quantum computer, Paradigm, via its partner Dan Robinson, unveiled an innovative proposal: Provable Address-Control Timestamps (PACTs). This mechanism allows Bitcoin holders, like Satoshi Nakamoto, to prove their ownership without moving their funds or revealing their identity. Concretely, PACTs operate in three stages:

1. Silent Commitment: The holder generates a time-stamped crypto proof via OpenTimestamps, at no cost.
2. Expectation: Data remains private, even if a soft fork freezes vulnerable addresses.
3. Secure redemption: In the event of a quantum threat, a STARK (zero-knowledge) proof allows funds to be released without disclosing sensitive information.

This solution avoids the dilemma of BIP-361, which required holders to reveal their identity to protect their assets. With PACTs, Satoshi could secure his 1.1 million BTC without revealing himself, while preserving the decentralization and confidentiality of Bitcoin.

Bitcoin has already anticipated the quantum threat

Contrary to popular belief, Bitcoin has already integrated protections against quantum attacks from its design. According to an analysis by Bernstein, the network uses resilient signature algorithms like ECDSA, which, while vulnerable in the long term, are hardened by mechanisms like single-use addresses and hierarchical keys (BIP-32).

However, pre-2012 addresses, like Satoshi's, remain exposed, as they do not benefit from these modern protections. This is where Paradigm PACTs intervene. They close this gap by enabling a secure transition to quantum-resistant proofs, without requiring forced migration.

Bitcoin has therefore always been proactive in the face of technological threats. Regular soft forks, like Taproot, show its ability to scale. With PACTs, the network could become completely resistant to quantum attacks, while preserving its ethos of decentralization and confidentiality.

Paradigm PACTs offer an elegant solution to protect the funds of Satoshi and early bitcoin adopters. But this innovation raises a question: should we sacrifice a little decentralization of BTC for absolute security in the face of quantum?
