Abstract: This application discloses a retransmitted data sending method, a retransmitted data receiving method, and a related apparatus, and relates to the field of communications technologies. In this solution, a transmit end generates a retransmitted codeword based on information bits of each codeword corresponding to an incorrect MPDU, where the retransmitted codeword includes a codeword having some of information bits included in the incorrect MPDU. For the codeword having some of information bits included in the incorrect MPDU, the transmit end punctures a correctly received information bit in the codeword, and then sends the information bit. In this way, a receive end may directly perform combined decoding or joint decoding on an LLR of a codeword of a retransmitted MPDU and an LLR of a codeword of an MPDU that is incorrectly received last time. This improves transmission efficiency and transmission reliability.

Abstract: This disclosure enhances a resilient high-bandwidth state-transition computer by incorporating a novel decentralized platform. The decentralized platform introduces a hierarchical, multi-level architecture utilizing node-sets and validation clusters to achieve exceptional scalability, fault tolerance, and data integrity. Entities, comprising distinct data sets, are distributed across node-sets, each maintaining a blockchain to record state changes. Node-set-level Merkle trees provide efficient data verification within node-sets, while a global Merkle tree combines node-set states into a unified representation of the global state, verified through consensus among validation clusters. This multi-dimensional cryptographic linking, enhanced by inter-node-set activations, creates a robust and tamper-proof system capable of handling millions of entities and ensuring data consistency across a distributed network.
