Mitigating information asymmetries to achieve efficient peer-to-peer queries
Bibliographic record
Abstract
Querying for a particular data item is perhaps the most important feature to be supported by peer-to-peer network infrastructures, and receives the most research attention in recent literature. Most existing work follows the line of designing decentralized algorithms to maximize the performance of peer-to-peer queries. These algorithms often have specific rules that peer nodes should adhere to (e.g., placement of data items on particular nodes), and thus assume that peers are strictly cooperative. However, in realistic peer-to-peer networks, selfish and greedy peer nodes are the norm, and query strategies degenerate to random or flooding based searches. In this paper, we explore the design space with respect to query efficiency in selfish peer-to-peer networks where nodes have asymmetric information, and apply the signaling mechanism from microeconomics to facilitate the sharing of private information and thus improve search efficiency. We extensively simulate the signaling mechanism in the context of other alternative solutions in selfish networks, and show encouraging results with respect to improving query performance.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
