quantumcomputer

Singapur şirkəti Horizon Quantum, dövlət şəhərində kommersiya məqsədli istifadə üçün ilk kvant kompüterini işə saldı. Bu haqda CNBC məlumat verir.
Şirkət, maşının tam işə hazır olduğunu bildirdi. O, Maybell Quantum, Quantum Machines və Rigetti Computing-dən olan komponentləri birləşdirir.

Two Revolutions One Myth

Quantum Computing and Bitcoin represent two of the most transformative technologies of the 21st century one redefining computation the other redefining money A persistent narrative claims that quantum computers will eventually break Bitcoin rendering it obsolete While the concern stems from real science the reality is more nuanced quantum computing is unlikely to defeat Bitcoin Here is why

Understanding the Players

Quantum Computing Beyond Binary
Unlike classical computers that use bits 0s and 1s quantum computers use qubits which can exist in multiple states simultaneously thanks to superposition and entanglement This allows them to solve certain complex problems exponentially faster Their potential is revolutionary for fields like drug discovery material science and optimization

Bitcoin Digital Scarcity
Bitcoin is a decentralized digital currency secured by cryptography and a public ledger called the blockchain Its security relies on
1 Cryptographic hash functions SHA256 for linking blocks
2 Digital signatures ECDSA for authorizing transactions
3 Proof of work consensus for network agreement

The Quantum Threat Narrative

The fear centers on two potential attacks

1 Breaking Elliptic Curve Cryptography
Quantum computers using Shors algorithm could theoretically derive private keys from public keys allowing theft of funds

2 Mining Dominance
Using Grovers algorithm quantum computers could potentially mine Bitcoin faster threatening decentralization

Why Quantum Computing Will Not Kill Bitcoin

1 Bitcoin Is Adaptable
Bitcoin has undergone numerous upgrades such as SegWit and Taproot and can implement quantum resistant cryptography Algorithms like lattice based cryptography already exist and can be integrated long before quantum computers pose a real threat The networks decentralized governance allows for coordinated response to existential risks

2 The Timeline Mismatch
Useful stable quantum computers capable of breaking ECDSA are likely decades away from practical deployment Estimates vary but most experts believe we are 10 to 30 years from cryptographically relevant quantum computers Bitcoin developers have ample time to prepare

3 Not All Bitcoin Is Vulnerable
Even if quantum computers could derive private keys from public keys this only affects exposed public keys Currently only addresses that have been used to spend funds reveal their public key Unspent outputs from P2PKH addresses remain protected by hash functions until they are spent Users could move funds to quantum safe addresses during a transition period

4 Mining Is Not Trivial
Quantum advantage in mining is limited Grovers algorithm offers only a quadratic speedup for hashing meaning quantum computers would need to be extraordinarily efficient to outcompete specialized ASIC miners The economic and energy barriers remain significant

5 The Broader Context
If quantum computers break Bitcoins cryptography they will also break traditional banking SSL TLS encryption and government systems Global urgency to upgrade cryptographic standards would emerge with Bitcoin participating in that transition

The Real Timeline A Race Already Underway

Present Day to 2030s to 2040s plus
Bitcoin development of quantum resistant solutions
Gradual adoption of post quantum cryptography
Classical mining continues dominance
Quantum computers advance in controlled environments

Conclusion Evolution Not Extinction

The relationship between quantum computing and Bitcoin is better framed as a challenge to overcome not a death sentence Bitcoin has survived countless predictions of its demise from regulatory crackdowns to forks to market crashes by adapting

Rather than killing Bitcoin quantum computing might even strengthen it by forcing earlier adoption of advanced cryptographic techniques The narrative that quantum will break Bitcoin underestimates both the resilience of decentralized systems and the foresight of their developers

In the end these two technologies may coexist each pushing the other toward innovation with Bitcoin remaining as ever a step ahead of those who predict its end
