A Talk by Kostas Kryptos Chalkias at Seoul National University
Hosted by Decipher

Decipher and SNU's GECE recently co-hosted a special lecture featuring Kostas Kryptos Chalkias, Co-founder & Chief Cryptographer of Mysten Labs.

Special highlights included an in-depth discussion on why Sui will be quantum-resilient by incorporating Zero-Knowledge Proofs(ZK), an introduction to on-chain robotic systems, and exploring the relationship between blockchain and AI.

In the second half, Decipher's Wonjae Choi, a member of the Virtual Machine & Optimization Lab at the Department of Electrical and Computer Engineering, Seoul National University, introduced his research about blockchain security, privacy, cryptography and compilers.

- Encrypted Mempool Design: Traditional blockchain mempools are always vulnerable to either privacy issues or DoS attacks. To solve this, he designed an encrypted mempool that uses cryptographic techniques, including ZK, to ensure privacy while being resistant to DoS attacks.

- Unified Prover Framework for ZK: While ZK require various proving backends and hardware environments, there is currently no unified framework, leading to a reliance on manual optimization for each. His research aims to address this by integrating compiler framework methodologies to design and develop a Prover Intermediate Representation and a Unified Prover Runtime.

[ENG] The Bright and Dark Sides of Stablecoins, and Measures for Activation

Global regulatory alignment is forming as major countries like the US and EU institutionalize stablecoins. In this session, Decipher explored "The Bright and Dark Sides of Stablecoins, and Measures for Activation," deeply examining the need to introduce a KRW stablecoin amidst the spread of USD stablecoins and the limitations of CBDC.

This session illuminated the design principles and policy alternatives for the KRW stablecoin from an industry-legislation-infrastructure perspective, positioning it as a strategic option to protect the Korean Won's status and elevate Korea as a digital finance leader.

This article analyzes Off-Chain Computing as the strategy to overcome the fundamental scalability and cost limitations of blockchains, focusing on ZK (Zero-Knowledge Proof) and TEE (Trusted Execution Environment) as the core technologies for verifying off-chain results.

To reliably move complex execution outside the chain, ZK guarantees mathematical integrity, while TEE provides hardware-based confidentiality via a Secure Enclave. Although TEE is fast and practical, it relies on hardware manufacturers and faces security trade-offs.

The most promising future solution is a Hybrid Approach that leverages ZK-Proofs to verify the TEE process. This merges TEE's low overhead with ZK's rigorous mathematical assurance, which is essential for enabling complex applications like ZKML and Private DEXs.

The blockchain-based lending market faces a fundamental limitation: low capital efficiency due to demands for excessive collateral. This article deeply analyzes the utility and application of on-chain credit scoring(OCCS) as a strategy to resolve this issue.

Unlike existing financial systems, on-chain credit scoring generates an OCCS by analyzing real-time on-chain data, such as wallet activity, transaction records, and repayment history. This probabilistic risk score supports lending protocols in dynamically adjusting Loan-to-Value (LTV) ratios and liquidation thresholds based on risk, thereby maximizing the capital efficiency of lending.

Furthermore, on-chain credit scoring offers credit access to the financially underserved and presents a new standard for credit evaluation that protects personal information using Zero-Knowledge Proofs. This is set to be a key driver for the DeFi market's expansion into the uncollateralized lending sector and the enhancement of risk management efficiency.

Aaveโ€™s dominant position in DeFi lending is under the spotlight amid intensifying competition. This session by Decipher analyzed Aaveโ€™s architecture, V3, governance, and risk management infrastructure. It explored differences with protocols like Morpho via the Stream Finance case and Aaveโ€™s future.

The session highlighted V3โ€™s Isolation Mode and e-Mode for efficient borrowing, introducing ecosystem tools like Service Providers, AGRS, and Umbrella. GHO tokenโ€™s over-collateralized stablecoin role and governance processes were key.

This session emphasized Aaveโ€™s safety and reliability, offering insights into DeFiโ€™s future direction.
