According to the source, Charles Hoskinson said a 'poisoned transaction' in November split Cardano into two chains and created reimbursement uncertainty even for operators who followed protocol, source: Charles Hoskinson via X video posted Dec 20, 2025. That disclosure signals temporary consensus divergence that can affect ADA transaction finality and exchange processing until remediation, source: Charles Hoskinson’s description of a chain split via X video posted Dec 20, 2025. Traders should increase confirmation counts for ADA deposits/withdrawals, monitor official Input Output Global updates for fixes and a post‑mortem, and track order-book spreads and funding for liquidity stress, source: risk controls aligned with Hoskinson’s chain‑split disclosure via X video posted Dec 20, 2025.

According to @ItsDave_ADA, Cardano (ADA) has run for over eight years with no downtime, underscoring operational reliability relevant to network risk assessment for traders (source: @ItsDave_ADA on X, Nov 24, 2025). According to @ItsDave_ADA, a large-scale DDoS-style spam event in 2024 backfired when Anastasia Labs developers deregistered the attacker’s stake credentials based on community observations, clawing back ADA now directed to open-source Cardano development, which the author frames as a governance-positive outcome for the ecosystem (source: @ItsDave_ADA on X, Nov 24, 2025). According to @ItsDave_ADA, a recent poisoned-transaction attack briefly split the chain, but Ouroboros Proof-of-Stake Nakamoto consensus reconverged to a single canonical ledger as designed, highlighting consensus robustness and finality assurances that matter to transaction reliability and staking yields (source: @ItsDave_ADA on X, Nov 24, 2025). According to @ItsDave_ADA, these resilience events are positioned as strengthening confidence in Cardano’s throughput and staking security, points that can inform trading views on ADA’s network risk profile and on-chain participation dynamics (source: @ItsDave_ADA on X, Nov 24, 2025).
