According to the source, Charles Hoskinson warned that making crypto, including Cardano (ADA), post-quantum secure will require trade-offs across performance, decentralization, and user experience, necessitating careful design choices for any migration. source: Charles Hoskinson. Larger post-quantum signature schemes such as ML-DSA Dilithium have markedly bigger key and signature sizes than Ed25519, which can reduce transactions per second and raise on-chain fees on fixed-capacity L1s if implemented naively. source: NIST Post-Quantum Cryptography Standards FIPS 204; NIST PQC Project. Migration to post-quantum typically requires new address formats, key rotation, and wallet migration plans to protect existing funds from future quantum threats, implying operational overhead for users and infrastructure providers. source: NIST Post-Quantum Cryptography Project; NIST guidance on crypto agility. For ADA traders, watch Cardano communications on signature-scheme trials, throughput and block-size benchmarking, and wallet migration timelines, as these updates can directly affect network costs, user friction, and liquidity. source: Charles Hoskinson; NIST PQC standards.

According to @ItsDave_ADA, the author publicly asked whether 150k TPS can be reached, without providing chain identification, benchmarks, or a timeline (source: X post by @ItsDave_ADA on Dec 7, 2025, https://twitter.com/ItsDave_ADA/status/1997460984781525286). For traders, the absence of verifiable performance data or official confirmation means no validated fundamental catalyst yet; treat this as sentiment-only until reproducible throughput metrics are released by an official source (source: X post by @ItsDave_ADA on Dec 7, 2025, https://twitter.com/ItsDave_ADA/status/1997460984781525286). The post does not reference testnet or mainnet measurements, so no quantitative signal for fees, capacity, or on-chain throughput can be inferred at this time (source: X post by @ItsDave_ADA on Dec 7, 2025, https://twitter.com/ItsDave_ADA/status/1997460984781525286).
