The quantum future

Most blockchains are using a lock that works great against today’s digital thieves but could be picked easily by a quantum computer in the future.

$Minima uses a different kind of lock—one that even a quantum computer can’t crack because it’s based on a completely different mechanism (hash functions). This makes Minima’s system safer for the long term, especially as quantum computers get stronger. While other blockchains might need major upgrades to stay secure, Minima’s already got its “quantum shield” in place.

Minima is a blockchain designed with quantum resistance in mind, meaning it’s built to withstand potential attacks from quantum computers, which could break many traditional cryptographic systems. In simple terms, quantum computers are super-powerful machines that can solve complex math problems much faster than regular computers. Most blockchains, like Bitcoin or Ethereum, rely on cryptographic methods (e.g., ECDSA) that are secure against today’s computers but could be vulnerable to quantum computers in the future. This is because quantum computers could potentially crack the math behind these systems, exposing private keys and compromising security.

It uses a quantum-resistant signature scheme called Winternitz One-Time Signatures (WOTS+). Instead of relying on math problems like factoring large numbers or discrete logarithms (which quantum computers can solve efficiently using algorithms like Shor’s), WOTS+ is based on hash functions. Hash functions are considered quantum-resistant because they don’t have known vulnerabilities to quantum attacks, even with sufficiently large key sizes. This makes Minima’s transactions and wallets more secure against future quantum threats.
