The InfiniSVM Pipeline: From Ingress to Finalization
The journey of a transaction on Solayer Chain is a highly optimized, multi-stage pipeline designed for maximum efficiency. It begins at the ingress point, where transactions are received, their signatures are verified, and local deduplication is performed. From there, the verified transaction is sent to a pre-execution cluster, where it is speculatively executed. This is a crucial step, as it determines whether the transaction can follow a "simple path" or a "complex path."A simple path transaction, where all accounts are at the latest version, has its state change directly applied via RDMA to a local cache on the SDN. This is a near-instantaneous process that bypasses the need for further scheduling. A complex path transaction, on the other hand, where at least one account has a newer version, enters a local mempool. This mempool, with its sub-millisecond processing speed, is where the sequencer leverages specialized hardware and a dynamic scheduling algorithm to achieve optimal parallel execution.After execution, the state change is written to a sharded key-value store, ensuring that all account data is persisted and accessible. The transaction is then propagated through a global network of PoPs (Points of Presence) to be finalized by the hybrid consensus. This entire pipeline, from the moment a transaction is received to the moment it is finalized, is meticulously engineered to minimize latency and maximize throughput, making it a state-of-the-art system for high-performance blockchain processing.
