Main Post (Thread 1/3)Humanity's FIRST truly verifiable, auditable byte data on-chain has been achieved! This is not a whitepaper dream — it's a real transaction confirmed on the QCC test public chain (height 13, confirmed 2026-02-28 16:26:40 UTC).
Published directly via FChat Mini Program:
test.qccio.com/v1/hash/f9a35…
Full payload bytes decoded (UTF-8): "This is the first piece of trustworthy data published from mobile, fair and tamper-proof, released by QCC byte"
Signed with ML-DSA-87 (NIST post-quantum signature standard, formerly Dilithium5) — quantum-resistant even against future quantum threats. Signature hash on-chain, full 4627-byte signature verifiable off-chain.
This marks the true beginning of "byte data on-chain" in the internet era — data that is permanent, immutable, and no longer reliant on centralized servers.

Thread 2/3Why this milestone matters:
Traditional data: centralized, mutable, vulnerable
Now: One-click publish from mobile → Public chain confirmation → Auditable by anyone via API (browser explorer coming soon)
Full ML-DSA-87 params: pubkey 2592 bytes, seckey 4896 bytes, sig 4627 bytes
FChat enables the complete flow: keygen → sign → on-chain in a privacy-focused app
Next step: QCC public chain browser parser launching soon — everyone will be able to directly view and audit this historic "first byte on-chain" transaction!
