Daniel Eduardo Campos Peñuelas – Atomic Proof Pack v2 (with OpenTimestamps)

Description: This record contains the integrity verification file checksums.txt along with its OpenTimestamps (.ots) proof. The .ots proof provides a cryptographic attestation anchored into the Bitcoin blockchain, verifying the existence of the file at or before the attested timestamp. This ensures byte-exact authenticity and long-term verifiability of the contents. Contents: checksums.txt – SHA-256 checksums for all referenced files. checksums.txt.ots – OpenTimestamps proof file linked to the Bitcoin blockchain. Verification_Guide_for_checksums.txt.md – Instructions for independent verification. Verification Instructions: Install OpenTimestamps Client. Verify the proof: ots verify checksums.txt.ots Compare local hashes with those listed in checksums.txt to ensure no alterations.
