Near Warns Quantum Attacks Threaten Crypto Ownership; Testnet by 2026
What This Means
- →Quantum computing threats are escalating → long-term security of all crypto assets is now a key concern.
- →Near Protocol's proactive quantum-safe efforts → early mover advantage in future-proofing blockchain security.
- →Potential ownership crisis from quantum attacks → necessitates industry-wide cryptographic upgrades.

The Big Coin Report Take
Near One has issued a warning that future quantum computing attacks could lead to a crypto ownership crisis by making current cryptographic signatures vulnerable. This matters significantly for the entire crypto ecosystem as it undermines the fundamental security and proof of ownership for digital assets. The key development is Near's plan to roll out a quantum-safe signing testnet by Q2 2026, signaling a proactive approach to this long-term threat. Investors should watch for further developments in quantum-resistant cryptography and its adoption across major blockchain protocols to mitigate future risks.
What To Watch
- 1.If quantum-resistant standards emerge, watch for major protocol adoption rates as a leading indicator of network security.
- 2.Monitor the development and adoption of quantum-safe signing testnets across other Layer 1s as a flow metric.
- 3.The single most important macro risk is the pace of quantum computing advancements, potentially rendering current encryption obsolete and impacting all digital assets.
The Big Picture
This story reveals the market's growing awareness of long-term existential threats to cryptographic security. It highlights the critical need for continuous innovation in blockchain infrastructure to maintain trust and utility. Failure to adapt will lead to a fundamental erosion of digital asset value.
