• Packaging Tesseras for Debian 2026-02-16

  How to build and install the Tesseras .deb package on Debian/Ubuntu using cargo-deb.

• Packaging Tesseras for Arch Linux 2026-02-16

  How to build and install the Tesseras package on Arch Linux from source using makepkg.

• Phase 4: Storage Deduplication 2026-02-15

  A new content-addressable storage layer eliminates duplicate data across tesseras, reducing disk usage and enabling automatic garbage collection.

• Phase 4: Institutional Node Onboarding 2026-02-15

  Libraries, archives, and museums can now join the Tesseras network as verified institutional nodes with DNS-based identity, full-text search indexes, and configurable storage pledges.

• Phase 4: Performance Tuning 2026-02-15

  SQLite WAL mode with centralized pragma configuration, LRU fragment caching, QUIC connection pool lifecycle management, and attestation hot path optimization.

• Phase 4: Verify Without Installing Anything 2026-02-15

  Tesseras now compiles to WebAssembly — anyone can verify a tessera's integrity and authenticity directly in the browser, with no software to install.

• Phase 4: Punching Through NATs 2026-02-15

  Tesseras nodes can now discover their NAT type via STUN, coordinate UDP hole punching through introducers, and fall back to transparent relay forwarding when direct connectivity fails.

• CLI Meets Network: Publish, Fetch, and Status Commands 2026-02-15

  The tesseras CLI can now publish tesseras to the network, fetch them from peers, and monitor replication status — all through a new Unix socket RPC bridge to the daemon.

• Phase 4: Heir Key Recovery with Shamir's Secret Sharing 2026-02-15

  Tesseras now lets you split your cryptographic identity into shares distributed to trusted heirs — any threshold of them can reconstruct your keys, but fewer reveal nothing.

• Phase 4: Encryption and Sealed Tesseras 2026-02-14

  Tesseras now supports private and sealed memories with hybrid post-quantum encryption — AES-256-GCM, X25519 + ML-KEM-768, and time-lock key publication.

• Phase 3: Memories in Your Hands 2026-02-14

  Tesseras now has a Flutter app and an embedded Rust node — anyone can create and preserve memories from their phone.

• Reed-Solomon: How Tesseras Survives Data Loss 2026-02-14

  A deep dive into Reed-Solomon erasure coding — what it is, why Tesseras uses it, and the challenges of keeping memories alive across centuries.

• Phase 2: Memories Survive 2026-02-14

  Tesseras now fragments, distributes, and automatically repairs data across the network using Reed-Solomon erasure coding and a bilateral reciprocity ledger.

• Phase 1: Nodes Find Each Other 2026-02-14

  Tesseras nodes can now discover peers, form a Kademlia DHT over QUIC, and publish and find tessera pointers across the network.

• Phase 0: Foundation Laid 2026-02-14

  The foundation crates for Tesseras are now in place — core domain types, cryptographic primitives, SQLite storage, and a working CLI.

• Hello, World 2026-02-13

  Introducing the Tesseras project — a P2P network for preserving human memories.
