Let say I have a Blockchain id id as below:-

id = "285a2d215ea5a866cbe38ba2f5de58e5ac497ed4984f31fa0307a5c3c5539f47"

I want to check whether id was previously submitted by myself. How can I check it? That would be even better if I can check when did I submit it.

Many thanks!

BlockchainPut writes an expression to the Wolfram blockchain but there's no signing involved, so no way to prove that you made that transaction. Note that blockchain functions are marked as experimental and that means they can change between releases. V12 introduced new blockchain functionalities focused on Bitcoin and Ethereum. You can see examples here:
