Mysten Labs demonstrates the feasibility of linear scalability of blockchain using the technology prototype "Pilotfish" on Sui
ChainCatcher news, according to Chainwire, Mysten Labs announced today that it has made progress in expanding blockchain capacity. During the testing and development process in the Sui blockchain environment, Pilotfish (Sui expansion prototype) achieved an 8-fold increase in throughput with the support of 8 machines, demonstrating the possibility of linear scalability. Notably, as more machines were added during testing, the latency per transaction decreased, which for the first time on a blockchain proved the feasibility of linear scalability for low-latency blockchain transactions. This proof of concept has been formally presented in the form of an academic preprint titled "Pilotfish: Decentralized Transaction Execution for the Sui Blockchain."Pilotfish achieves its scalability by enabling a single validator to execute transactions across multiple machines. Specifically, Pilotfish divides the validation function into three key roles: (1) Master Nodes, which use high-throughput consensus to process and order transactions; (2) Sequencing Workers (SW), which store transactions and schedule their execution; (3) Execution Workers (EW), which store the blockchain state and execute transactions received from SW. Different components can reside on multiple different machines to more precisely increase the system's capacity.In experimental results, Pilotfish has achieved success in linear scalability, low latency, and support for various workloads. In testing, Pilotfish reduced network response times and kept latency below 20ms. Future plans include enhancements such as multiple Sequencing Workers, sharding replication, and ultra-high-speed networks.
