Bytestamp (
http://www.bytestamp.net) is a blockchain notarization service active since 2014.
Ten years ago, I announced it in this topic:
https://bitcointalk.org/index.php?topic=781281Now ByteStamp has added another blockchain to notarize its data.
In addition to use Datacaoin blockchain, it now notarizes also on CHIA blockchain (
https://www.chia.net/).
Each ByteStampProof, each ByteStamp Digital Asset (
https://bitcointalk.org/index.php?topic=2248452) and even cross chek points (
https://bitcointalk.org/index.php?topic=955473.0) are now notarized both on Datacoin Blockchain and on CHIA blockchain.
This affects every data sent to ByetStamp, even data you mange with your own developed software using ByteStamp API (
https://bitcointalk.org/index.php?topic=5294700).
And also files notarized by Windows ByteStamp Software (
https://blockchain.bytestamp.net) (you must click this URL from Windows OS to see the software)
If you go to
https://www2.bytestamp.net/docs/qdoc/it/7344ae399dae54dad079f31d5f034ace you can see a double blockchain ByteStampProof, one on Datacoin blockchain (on the right side) and another on CHIA blockchain (at bottom).
Here
https://www2.bytestamp.net/c/c/pgVyVB4606 you can see a ByteStampProof written to CHIA DataLayer, and have the proof of inclusion on CHIA blockchain by using the sync_status field. You can verify CHIA block and transaction on third party services, too.
If you scroll at bottom of the page there are instructions to verify CHIA ByteStampProof on your own.
There is also an explanation on how to read ByteStamp JSON written to chia Data Layer, if you are a developer.
So, every ByteStampProof now as a strength of a double blockchain.
Also, because we write last Datacoin block hash on Chia Data Layer, we strengthen Datacoin blockchain with CHIA blockchain.
