Google Sets 2029 Post-Quantum Cryptography Deadline

Google has set 2029 as its target year to implement post-quantum cryptography across products. The company points to quantum hardware progress and improved error correction, and it warns that today’s encryption and digital-signature standards could become vulnerable. It also stresses the “store now, decrypt later” risk, pushing security planning to start immediately. In crypto, the quantum timeline is also shaping infrastructure work. The Ethereum Foundation launched a “Post Quantum Ethereum” resource hub and targets protocol-level quantum-resistant upgrades by 2029, with execution-layer work to follow. Solana introduced quantum-resistant vault infrastructure in early 2025, using hash-based signatures and per-transaction key generation, but users must opt into these specialized vaults rather than relying on standard wallets. Bitcoin’s stance remains divided. Blockstream co-founder Adam Back argues the threat may be overstated and years away. In contrast, security researchers support BIP 360, proposing new output types to reduce short-exposure quantum risk, with one estimate putting implementation up to seven years. For traders, this is not an immediate catalyst for major coins. Instead, the post-quantum cryptography narrative is shifting toward concrete migration timelines, which may boost attention on long-term infrastructure themes rather than trigger near-term price moves.
