Charles Hoskinson Dey Test ZK Recovery Smart Contract to Make Cardano Wallet Security Stronger

Charles Hoskinson, the founder of Cardano, talk on June 26 say im don start to experiment with one recovery smart contract for Cardano wallets. The model go use zero-knowledge proof to confirm say user get the 24 keywords wey generate wallet, so that contract fit distribute Ada and Cardano native tokens from one shared pool. Hoskinson talk say im plan to sync with Pi Lanningham, Sebastien Guillemot and the Midnight team on wetin dem discover.

Hoskinson Describe Early ZK Recovery Experiment

Hoskinson post describe early technical experiment, no be finished product, official wallet feature or deployed protocol. The recovery smart contract wey dem propose go “vend out” funds from one pool after e verify zero-knowledge proof wey tie to possession of the 24 wallet keywords.

For that model, user no go need to publish seed phrase or give recovery words to third party. Instead, the user go generate cryptographic proof wey confirm knowledge of the required secret. The smart contract go verify the proof and, if e valid under the contract rules, e go perform the recovery-related action.

Hoskinson add two short replies wey give more context to the idea. For one response, e talk say the approach “solves the white hat issue.” For another one, e write say “the blockchain becomes the custodian.” Those comments dey point to recovery model wey move part of the process from manual coordination and trusted intermediaries go on-chain verification.

Dem never publish the technical design. Public details never dey yet on which zero-knowledge system dem go use, how the pool go dey funded, who go define distribution rules, how dem go prevent abuse, or whether the approach go compatible with existing wallet implementations.

SecondFi Incident Put Wallet Recovery Back in Focus

The experiment show some days after the security incident wey involve SecondFi, the Cardano wallet wey dem formerly know as Yoroi. SecondFi dey allow users manage funds, send and receive tokens and interact with the Cardano ecosystem. The incident don renew attention on how self-custody systems dey handle recovery when the problem connect to wallet infrastructure and no be the Cardano protocol itself.

SecondFi confirm say three external attacks drain roughly 16 million ADA from 374 wallets. Dem describe the root cause as flaw for im proprietary wallet generation software. Another 129 million ADA route go third-party custodian before attackers fit reach am. Some security and on-chain sources don discuss broader estimates of potentially affected funds, but make people separate those figures from the officially confirmed drained amount.

Hoskinson no talk directly say im ZK recovery experiment na response to the SecondFi incident. The connection na contextual, based on timing and subject matter. Both developments relate to the same broader issue, wey be safer wallet recovery and emergency handling inside self-custody environment.

For Cardano users, recovery still remain one of the hardest parts of wallet security. Lost seed phrase, compromised wallet generation process or unsafe emergency recovery flow fit undermine the benefits of direct asset control. Zero-knowledge recovery model go aim to preserve privacy while e allow contract verify say user get the required recovery secret.

Pi Lanningham, Guillemot and Midnight Add the Technical Context

Hoskinson talk say e go sync with Pi Lanningham, Sebastien Guillemot and the Midnight team on the findings. Lanningham, wey people know on X as @Quantumplation, na CTO of Sundae Labs and operator of the Cardano stake pool 314pool. Im work for Cardano DeFi and technical education dey provide relevant context for discussion about smart contract recovery design.

Guillemot na long-time Cardano developer wey dey associated with Paima Studios and dcSpark. Midnight self don feature am inside im developer ecosystem content, where dem discuss im work for connection with blockchain gaming and zero-knowledge technology. Im inclusion connect the recovery topic to wallet infrastructure, developer tooling and application-level design.

Midnight na privacy-focused network wey connect to the Cardano ecosystem. Im public materials dey describe work around zero-knowledge applications, programmable data protection and developer tooling for data-protecting decentralized applications. That one make Midnight relevant to recovery concept where sensitive information must be proven without to reveal am.

The role of Midnight for this specific experiment never get technical definition. Hoskinson don confirm consultation with the Midnight team, but e never confirm use of specific Midnight tool, runtime or production architecture.

The current experiment therefore best make we understand am as early Cardano wallet recovery initiative. Further development go require technical definition about how dem go generate the proof, how the pool go dey governed, how dem go validate claims and how the model go avoid turning recovery into new custody risk.
