Cardano is facing renewed questions about its network resilience after a malformed transaction triggered a temporary chain split this week.
A pseudonymous X developer known as Homer J caused the November 21 incident and revealed that he relied on artificial intelligence tools.

Why Cardano Experienced a Temporary Chain Split
The developer stated that they had no malicious intent and the action was a “failed personal challenge.”
In the post-mortem, Intersect, an organization within the Cardano ecosystem, said an oversized hash caused the flaw by slipping through initial validation checks.
This created a temporary fork between the chain carrying the poisoned transaction and a second, healthy chain.
Intersect said the bug had been masked for years by older ledger versions and standard transaction tooling.

It surfaced only in recent node releases combined with specialized submission methods.
While the split caused many wallets and decentralized applications to become inoperative, block production continued.
Following the incident, staking pool operators were instructed to download an updated node release, which enabled the ecosystem to consolidate the two chains back into a single canonical history.
Meanwhile, Cardano’s blockchain founder Charles Hoskinson has hinted that the attacker could face legal consequences for his actions.

Cardano’s Technology Earns Praise
Cardano’s technology response to the incident drew unexpected praise from outside its community.
On November 23, Solana co-founder Anatoly Yakovenko praised Cardano’s consensus design while hailing the network’s response to the issue.

The Solana network is one of Cardano’s largest rivals, and the two often compete for developer and investor attention.
Yakovenko noted that maintaining network continuity without proof-of-work is “extremely hard,” and argued that the protocol behaved as intended under stress.
His comments stand out in an industry where rival ecosystems rarely commend each other’s architecture.
Cardano developers and operators treated the acknowledgment as validation of the network’s ability to withstand edge-case failures without widespread disruption.
