The Cardano Foundation emphasizes innovation and research in blockchain technology. Their research paper, “MACS: A Multi-Asset Coin Selection Algorithm for UTxO-based Blockchains,” presented at the 2023 IEEE International Conference on Blockchain, highlights the benefits of the MACS algorithm. MACS optimizes transaction fees, UTxO pool size, and user privacy, improving UTxO-based blockchains. Though tested in simulations, it shows promise for enhancing cost, speed, and privacy in blockchain transactions, with further real-world testing needed.
