Solana co-founder praises resilience of the Cardano chain after a temporary fork, highlighting PoS stability and future upgrades.
Cardano’s blockchain demonstrated resilience following a temporary chain split between November 22-23, 2025.
The fork, triggered by an AI-related node bug, resolved quickly without halting transactions. Solana co-founder Anatoly Yakovenko publicly praised Cardano’s consensus, noting the difficulty of securing proof-of-stake systems without proof-of-work.
Observers highlighted that the network’s recovery showcased the impact of a decade of formal methods and high-assurance engineering.
Cardano’s Chain Split and Immediate Response
The chain split affected only a small portion of nodes interpreting a malformed transaction differently.
Cardano quickly resolved the fork with a standard node upgrade. No funds were lost, and operations continued uninterrupted, according to founder Charles Hoskinson.
CARDANO SURVIVED WHAT MOST PROOF-OF-STAKE NETWORKS COULDN’T😱😱😱@IOHK_Charles says while outsiders were spiking the ball, claiming Cardano isn’t invincible, they don’t understand a fork like this in most proof-of-stake systems would be nearly impossible to fix.

Most proof-of-stake networks would need a hard fork or checkpoints to recover, but Cardano avoided that entirely.
The event showed Cardano can handle problems smoothly. The temporary fork proved the network is built to prevent lasting issues.
Analysts said it is rare for a PoS network to recover so quickly without outside help. Yakovenko called this a proof of Cardano’s solid engineering.
The network’s strength comes from the Ouroboros consensus system.
Cardano tests its code carefully to prevent problems. The chain split showed these protections working. The event boosted trust in the network’s stability during surprises.
Recovery speed also matters for market participants.
Exchanges and traders saw minimal impact on transactions. The network maintained standard throughput throughout the split. Observers considered this a rare demonstration of operational continuity in PoS chains.
Industry Recognition and Protocol Validation
Yakovenko praised Cardano on social media, noting that building secure PoS systems without proof-of-work is highly challenging. The co-founder credited the network’s decade-long focus on formal methods.

Comments from Mintern highlighted that most PoS networks could not fix a similar fork without permanent damage. Cardano’s performance drew attention as a model for resilient PoS development.
Hoskinson described the attack as premeditated, exploiting a specific edge case in consensus rules. The network neutralized the attack with no hacks or fund loss.
A simple upgrade was sufficient, avoiding costly interventions. Observers emphasized that Cardano’s protocol functioned exactly as designed under pressure.
Looking forward, Cardano plans to integrate the Leios upgrade in 2026. The upgrade aims to make recovery automatic and instantaneous for similar events.
The network’s resilience will be locked in for the long term. Besides, analysts anticipate it could set a benchmark for other PoS chains.
Industry recognition from Solana adds further credibility. Yakovenko highlighted Cardano’s engineering approach.
The praise signals growing respect between major blockchain networks. It reinforces the importance of robust consensus in competitive markets.

What PoS Networks Can Learn from Cardano
The fork illustrated the challenges of securing PoS chains against specific attacks.
Experts note that pre-planned exploits can destabilize networks lacking formal safeguards. Cardano’s ability to recover without external measures sets it apart. The episode offers a practical case study for developers and investors.
Transaction integrity remained intact throughout the incident. The network prevented any double-spending or operational loss. This demonstrates that PoS chains can maintain trust with proper design.
Traders saw the network stay strong without affecting trades.
Other proof-of-stake projects may take note. Key lessons include checking code early and having easy ways to fix nodes.
Future PoS networks are likely to use these methods. Cardano’s quick recovery could set a new standard for safety.
