Each signer reviews the proposal via a secure dashboard. Alice signs with her key share, Bob signs, Charlie signs. The threshold is 2-of-3, so only two signatures are required, but all three may sign.
The bank’s file orchestrator (FileDot agent) hashes the 50 GB file into a root hash H_root . filedot tss
Similarly, standard TSS implementations (common in blockchain wallets) are excellent for signing small transactions but struggle with because they were not designed for streaming data. Each signer reviews the proposal via a secure dashboard
The system aggregates the partial signatures into a full TSS signature Sig_total over H_root . The bank’s file orchestrator (FileDot agent) hashes the
To adopt FileDot TSS, look for enterprise file transfer platforms that advertise and multi-party approval workflows . Open-source reference implementations are also available in Go and Rust, allowing you to build a custom solution tailored to your threat model.
The FileDot engine opens an encrypted channel and streams the 50 GB in chunks. Each chunk carries a proof linking back to H_root . If any chunk fails integrity, the receiver rejects the entire file.
