# A New Cryptography Tool Could Help Bitcoin Survive the Quantum Era Project Eleven's faster zero-knowledge proof allows Bitcoin holders to verify wallet ownership without exposing keys. - **Source:** [DailyCoin](https://brifing.si/source/3e9b0f85-cb2f-40ee-ba61-db9410cf0937) - **Published:** 2026-07-18 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/a796980f-fa73-4182-8e26-a86b7bec53e7 ## Preparing for the Quantum Era Bitcoin's security model relies on cryptography that could be challenged by powerful quantum computers. Project Eleven has developed a zero-knowledge proof prototype that allows users to prove wallet ownership without exposing private keys. ## What is Zero-Knowledge Proof? Zero-knowledge proof allows one party to prove they control certain information without revealing the information itself. Project Eleven's approach lets users prove control over the cryptographic structure behind a wallet address. ## Limitations of the Technology Project Eleven's prototype is still in its early stages and unaudited. The system does not currently allow users to recover assets on any live blockchain and requires protocol-level support on the Bitcoin network. ## Quantum Threat and Bitcoin Bitcoin and other cryptocurrencies rely on elliptic-curve cryptography to verify wallet ownership and authorize transactions. Quantum computers could potentially threaten this security model. ## Future-Oriented Research Project Eleven's research explores whether quantum-resistant recovery proofs could provide another mechanism for crypto users to protect access to their funds. ## Why It Matters This technology could be a crucial step in helping crypto users protect access to their funds as quantum computing advances and ensuring Bitcoin's future security. ## Sources covering this story - https://dailycoin.com/a-new-cryptography-tool-could-help-bitcoin-survive-the-quantum-era/ — --- _Summary written by Brifing from the original reporting.
