Composability Labs is making strides in the decentralized finance (DeFi) sector with the development of Spark, a high-speed onchain central limit order book (CLOB) designed to leverage Polygon (MATIC) Miden’s state-minimization features, according to Polygon Technology.
Addressing State Bloat in Blockchain
State bloat is a persistent issue in blockchain technology, where increased usage leads to an accumulation of data, slowing down the system and increasing transaction costs. Polygon Miden tackles this problem by incorporating state minimization, allowing block production and verification without storing the entire state of the zkVM rollup. Instead, zero-knowledge proofs (ZKPs) enable users to store their own data, with the rollup only tracking verifiable commitments to that data.
Introducing Spark
Spark is a decentralized order book that will operate on Polygon Miden, utilizing a state-minimized design. This approach aims to optimize the implementation of order books in the cryptocurrency space, enhancing the efficiency and transparency of DeFi transactions. The unique architecture of Polygon Miden supports this by ensuring all execution occurs onchain, avoiding the typical trade-offs associated with off-chain solutions.
Advantages of Spark
Spark brings several key benefits to DeFi users:
Onchain Execution: Ensures greater transparency and security compared to off-chain solutions.Advanced Order Types and Market Depth: Supports complex order types and provides a clear view of market depth and liquidity, essential for professional traders.Transparency: Offers easy access to transaction data, enhancing trust and verifiability.Reduced Trade-offs: Mitigates the transparency and security risks associated with off-chain order books.Support for Trading Strategies: Incorporates standard practices for efficient and effective trading operations.
Design Approach for Perpetuals and Spot Markets
Composability Labs is committed to advancing onchain DeFi execution with high-performance, order-book-based protocols. Polygon Miden’s account abstraction and note architecture improve user experience by ensuring efficiency and sovereignty. The state-minimized design enables a locally-executed, onchain CLOB, which is crucial for the development of spot and perpetual markets.
Additional features, such as an onchain price oracle, are planned to enhance the functionality of perpetual markets. This could enable multiple notes to be consumed in one transaction, allowing for concurrent transactions and further improving efficiency.
Understanding Polygon Miden
Polygon Miden combines elements from Bitcoin and Ethereum, using customizable UTXOs (unspent transaction outputs) and client-side proving of transactions enabled by ZKPs. This design allows for parallel processing of transactions, significantly improving performance and scalability.
Polygon Miden’s innovative approach to blockchain design and its state-minimized environment make it a promising platform for the future of DeFi, particularly for order book-based protocols like Spark. As Composability Labs continues to develop Spark, the Ethereum DeFi landscape is set to benefit from enhanced trading infrastructure and improved user experience.
