A session at Authenticate 2025 which explores the nuanced dynamics between passkeys and verifiable digital credentials, and their technological foundations across usability, privacy, trust models, and ecosystems with the goal of answering whether passkeys and verifiable digital credentials are friends or foes—and how these technologies might collaboratively shape the future of secure, user-centric digital identity systems.
Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.
