- What happened
- Miners on SN105 (Beam) identified an apparent self-transfer exploit in which transfers show files already present at the destination, allowing unusually fast completions (one case cited at 2140 Mbps, ~400ms) that bypass genuine upload verification; one miner reported records suggesting roughly 100 UIDs involved across multiple groups. Separately, a validator-pointed benchmark destination (172.232.226.191:9000) was reported unstable, refusing connections and causing legitimate transfers from honest miners to fail, triggering 3x PRISM penalties and rank drops from Tier D to Tier E for some participants. The team temporarily raised Beam transfer pricing to $15 per TB as a short-term measure tied to the miner-owned transfer issue. Orchestrator operators also continued to report recurring NATS authentication-expired errors.
- Community
- Miners shared transfer IDs and timing data to document the exploit and debated whether it could be explained by legitimate caching, with one miner noting the etag used to verify uploads can be generated locally without an actual upload. A miner proposed an 'accredited account' system so only vetted customer traffic counts toward incentive, as a way to curb wash trading without banning accounts. Separately, miners affected by the unstable benchmark endpoint asked the team to filter or blacklist destinations that drop connections, and others troubleshot the NATS auth errors by rebuilding against the latest commit and matching API keys.
- Official
- The team stated the self-transfer exploit "is not tolerated and will be punished," with further information to come, and said a separate issue with stuck sell-allowance debt would be addressed separately. It also announced a temporary increase in transfer pricing to $15 per TB while the miner-owned transfer issue is addressed, calling the adjustment short-term.
