Abstract

fetched live from OpenAlex

The Lightning Network (LN) is a pioneering payment channel network developed to address Bitcoin’s scalability challenges. In LN, source nodes select transaction paths without knowing intermediary channel balances as channel balances are known only to their owners. Consequently, payments often fail when channels lack sufficient funds, forcing the source to retry the entire transaction. This paper introduces Bucket, a novel atomic-payment solution designed to reduce latency by minimizing these retries without requiring nodes to share their channel balances or the source node to lock additional funds. Bucket achieves this by routing multiple independent payment alternatives simultaneously in a “bucket,” each with its own route. Intermediate nodes decrypt all alternatives, select a viable next hop based on their local channel balance knowledge, group relevant alternatives, and forward them in a new bucket. If a chosen route becomes blocked, Bucket supports efficient backtracking by enabling immediate previous nodes (not necessarily the source) to quickly select alternative paths. Simulation results using real $\mathbf{L N}$ data demonstrate that Bucket significantly reduces latency and improves transaction success rates, especially in challenging routing scenarios.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
