Cardano founder Charles Hoskinson has reaffirmed the blockchain’s long-term strength, insisting that the network remains fundamentally secure as it prepares for what he described as its biggest protocol upgrade to date.
Meanwhile, his comments came during a lengthy community update addressing the recent SeccFi wallet security incident, where he distinguished between vulnerabilities affecting a third-party wallet implementation and the Cardano blockchain itself.
According to Hoskinson, while the hack has raised important questions about wallet security and ecosystem governance, it has not impacted the integrity of Cardano’s core protocol.
Notably, Hoskinson revealed that he has been testing new features enabled by Cardano’s upcoming hard fork, particularly advanced zero-knowledge proof verification capabilities.
Speaking last Monday, Hoskinson said he had spent the weekend successfully implementing a Groth16 verifier on the Cardano preview network, demonstrating new capabilities introduced by Cardano’s upcoming network upgrade.
 
The upgrade introduces new primitives capable of verifying complex cryptographic proofs while allowing users to prove wallet ownership without exposing sensitive information. Hoskinson explained that these improvements could eventually support sophisticated recovery mechanisms for compromised wallets if needed.
Although the work was inspired by the SeccFi incident, he noted that the research also showcased how far Cardano’s smart contract capabilities have evolved.
“It’s nice to know that Cardano’s really moved forward and it is able to do lots of interesting cool things,” he stated.
He added that these capabilities are portable across different wallet interfaces and demonstrate significant progress in Cardano’s zero-knowledge infrastructure.
Throughout his update, Hoskinson repeatedly emphasized that the ongoing investigation relates to SeccFi’s wallet software rather than Cardano’s blockchain.
He explained that preliminary findings point to modified cryptographic code introduced after SeccFi moved away from the open-source Yoroi wallet codebase. However, he cautioned that the full scope of the compromise remains unknown until an independent security audit is completed.
Rather than rushing to implement recovery measures, Hoskinson argued that objective forensic analysis should determine whether signing keys, derivation paths, or additional user data were affected.
He also called for greater transparency from the organizations involved, saying trust can only be rebuilt through independent verification instead of assurances.
Despite the recent setback, Hoskinson believes Cardano’s broader development roadmap remains firmly on track.
He pointed to several ongoing initiatives, including RealFi, Bitcoin DeFi integration, Midnight, and partner chain development, as evidence that ecosystem growth continues at a rapid pace.
Notably, he reminded the community that Cardano is approaching what he considers the most significant protocol upgrade in its history.
“Cardano has not been hacked. The chain still operates, blocks are still being made in a pretty consistent rate, and we’re just about to go through the largest upgrade in the history of Cardano soon.”
Hoskinson also argued that the incident could ultimately strengthen the ecosystem by encouraging higher wallet security standards, wider adoption of open-source software, AI-assisted code auditing, certified cryptographic libraries, and even blockchain-native wallet insurance.
Looking beyond the immediate challenges, Hoskinson expressed confidence that Cardano’s governance institutions are responding appropriately and that the ecosystem is capable of learning from setbacks without compromising its long-term trajectory.
Hoskinson said the incident would ultimately benefit the ecosystem.
“The long-term consequences of this hack are every single holder of ADA will have more secure wallets and more options on their security… I think that’s a fundamental win for everybody here.”
At press time, ADA was trading at $0.1672, reflecting a 1.10% upsurge in the past 24 hours.
