Stored custody key material in the live demo is now sealed at rest: the active keyfile is a sealed v2 envelope with hybrid post-quantum plus classical protection, and the prior plaintext keyfile was removed from the active path. This closed a documented, signet-only tradeoff from the earlier prototype. The group address was preserved through the migration.

A signet transaction was broadcast after the migration; you can verify it on the explorer link above.

The Decern demo has produced real, co-signed Bitcoin signet transactions during verified deployment runs. Two such transactions have broadcast live, each carrying a post-quantum co-signature bound to that exact transaction: one on July 12, 2026, and one on July 14, 2026. Both are viewable on any public signet explorer. Both are on Bitcoin signet, a public Bitcoin test network; no real assets were involved in either transaction.

During a live run, the demo stream displays this step: “Each approving party added a post-quantum co-signature bound to this exact transaction.” That co-signature is part of the signing evidence, designed for independent replay verification: a standalone verifier can re-check the recorded evidence without trusting the operator. The transaction itself is verifiable by anyone on a public explorer; deeper evidence replay is part of the reviewer package.
