# Secure Multi-Party Computation ⎊ Area ⎊ Resource 18 --- ## What is the Cryptography of Secure Multi-Party Computation? Secure Multi-Party Computation (SMPC) represents a cryptographic protocol suite enabling joint computation on private data held by multiple parties, without revealing that individual data to each other. Within cryptocurrency and derivatives, this facilitates collaborative model training for risk assessment or algorithmic trading strategies, preserving proprietary data advantages. Its application extends to decentralized exchanges, enabling privacy-preserving order matching and settlement processes, crucial for maintaining market integrity. The core principle relies on secret sharing and homomorphic encryption, ensuring computational results are accurate while upholding data confidentiality. ## What is the Computation of Secure Multi-Party Computation? Implementing SMPC in financial derivatives pricing and trading necessitates substantial computational resources, particularly with complex models like those used for exotic options. This is because the cryptographic operations involved add overhead to standard calculations, impacting latency and throughput. However, advancements in hardware acceleration and optimized cryptographic libraries are mitigating these performance constraints, making real-time SMPC feasible for certain applications. The ability to jointly compute derivatives pricing without revealing individual trading books offers a significant advantage in competitive markets. ## What is the Privacy of Secure Multi-Party Computation? The increasing regulatory scrutiny surrounding data privacy, exemplified by frameworks like GDPR, drives the adoption of SMPC within the financial sector, including crypto markets. It allows institutions to comply with data protection regulations while still participating in collaborative analytics and trading activities. Specifically, SMPC can be used to perform anti-money laundering (AML) checks across multiple exchanges without exposing sensitive customer data, enhancing regulatory compliance and fostering trust. This capability is particularly relevant for decentralized finance (DeFi) protocols seeking to bridge the gap between privacy and regulatory requirements. --- ## [Delegatecall](https://term.greeks.live/definition/delegatecall/) An opcode allowing a contract to execute external code while maintaining its own storage and state context. ⎊ Definition ##
