Submission Window

Each layer places this entropy observation between a submitted-after edge and a submitted-before edge. Only the submitted-before edge is grounded outside Truestamp, by a public-chain commitment transaction. The submitted-after edge is asserted by Truestamp's own block ordering and is not established by this proof. A witness Truestamp writes no commitment to, such as the NIST Beacon, can speak only to the submitted-after edge and so forms no window of its own.

Truestamp blocks
Truestamp-asserted window of 59 s

Both edges are read from Truestamp's own block clock. Neither is confirmed by an outside witness.

Stellar
Bounded to a 3 m 11 s window

The submitted-before edge comes from the Stellar commitment transaction. The submitted-after edge is asserted by Truestamp's block ordering, not by Stellar.

Bitcoin

The submitted-before edge comes from the Bitcoin commitment transaction. The submitted-after edge is asserted by Truestamp's block ordering, not by Bitcoin.

Truestamp writes no commitment to the NIST Beacon

The NIST Randomness Beacon is a signed public beacon, not a chain Truestamp commits to, so it can witness only the submitted-after edge. The pulse value is independently checkable in NIST's public records; its ordering against this subject is asserted by Truestamp's block ordering.
