I am signaling that the post-quantum public keys listed in the tags of this event were generated by me and I hold the private keys. I may use these keys in the future as successors to my current Nostr identity. My current identity: npub: npub1rmz9gu6de0m0u4ysrn39crrud099ahvfgs6pvasl4hpjr5ud7yus54xv06 hex: 1ec454734dcbf6fe54901ce25c0c7c6bca5edd89443416761fadc321d38df139 This attestation is established pre-quantum and anchored to the Bitcoin blockchain via OpenTimestamps. Post-quantum public keys in tags: ML-DSA-44 (Dilithium, FIPS 204, NIST Level 2) ML-DSA-65 (Dilithium, FIPS 204, NIST Level 3) SLH-DSA-128s (SPHINCS+, FIPS 205, NIST Level 1) Falcon-512 (FIPS 206 draft, NIST Level 1) ML-KEM-768 (Kyber, FIPS 203, NIST Level 3) Each post-quantum key has cryptographically signed this attestation. This event is pending timestamp on the Bitcoin blockchain via OpenTimestamps. Verify this attestation: Created at:

✅ The OpenTimestamps proof for my post-quantum key attestation has been confirmed in Bitcoin block 960117 (mined 2026-07-29T14:28:24 UTC). The link between my current Nostr identity and my post-quantum keys is now anchored to the Bitcoin blockchain and cannot be backdated. Verify it here: This is a reply to my original attestation announcement. The confirmed proof is carried in a new kind 9999 event referencing the original.
