What the Analysts Are Saying: The Quantum Threat to Bitcoin

1. Charles Edwards’ Warning
Crypto analyst Charles Edwards says the quantum threat is more urgent than many think. He believes the community should start working on quantum-resistant solutions by 2026.
He argues some are downplaying the danger to pump short-term price — but a real quantum attack could undermine Bitcoin’s cryptographic security entirely.

2. Google’s Breakthrough
Google researchers say a quantum computer could break RSA-like encryption with 20× fewer qubits than previously estimated.
Since Bitcoin’s cryptography relies on elliptic curve algorithms (ECDSA), this kind of quantum progress raises real concerns.
This is not just theory: Google’s “Willow” chip was cited as a step in that direction.

3. Timeline Risk
Some experts, like Solana’s co-founder Anatoly Yakovenko, estimate there's a 50/50 chance quantum computers strong enough to threaten Bitcoin could arrive in ~5 years.
A cybersecurity firm report says systems powerful enough to break Bitcoin’s encryption could emerge in 10–15 years.
On the other hand, skeptics (e.g., Michael Saylor) argue that quantum risk is highly exaggerated and more of a marketing tactic.

4. Security Implications
If quantum computers become capable, they could derive private keys from public keys, particularly for older Bitcoin addresses (like those never used after generation).
That could allow attackers to move or steal large amounts of BTC from vulnerable wallets.

5. What Can Be Done
Move towards post-quantum cryptography, which uses signature schemes designed to resist quantum attacks.
Avoid address reuse (so public keys are not exposed more than necessary).
Potentially perform a hard fork to adopt quantum-safe crypto schemes — though this is technically complex and controversial.

Why It Matters for Crypto Holders (and Your Audience)
Long-term risk: If quantum computers do become powerful enough, some Bitcoin held in older or reused addresses could be at real risk.
Proactive defense: The crypto community may need to act now (or soon) to upgrade Bitcoin’s security, not wait until the threat is immediate.
Education + awareness: For your content, this is a great topic — explaining quantum risk, why it matters, and what the Bitcoin community could or should do about it.

Not just hype: While some dismiss it, many credible analysts and quantum researchers take the threat seriously — your audience would benefit from a balanced view.

Kvantu datorzinātne ir moderns lauks, kas izmanto unikālās kvantu mehānikas īpašības, lai veiktu aprēķinus, kas pārsniedz klasisko datoru iespējas.
Savas būtības pamatā kvantu dators izmanto qubits (kvantu biti) vietā tradicionālajiem biti (0s un 1s). Qubiti var pastāvēt superpozīcijas stāvoklī, kas nozīmē, ka tie var vienlaikus pārstāvēt gan 0, gan 1. Tas ļauj kvantu datoriem apstrādāt milzīgu informācijas apjomu paralēli.
Vēl viens būtisks fenomens ir savērpšana. Kad qubits ir savērpti, viena qubit stāvoklis nekavējoties ietekmē otra stāvokli, neatkarīgi no attāluma. Tas ļauj kvantu datoriem veikt sarežģītas aprēķinus ar nebijušu ātrumu un efektivitāti.
