Sorry if that question sounds stupid, but I couldn't find any examples yet.
Could someone kindly post a simple example (or a link to) on how to notarize a string on flo blockchain with the help of the rpc-cli?
Maybe even how to access/decode the same string again from the rpc-cli.

Any help/example is greatly appreciated, TIA.

To put a floData message into the blockchain, you can use the qt-client, or use the RPC command sendtoaddress like this:

Code:

sendtoaddress "address" amount ( "comment" "comment_to" subtractfeefromamount replaceable conf_target "estimate_mode" "flodata" )
Send an amount to a given address.

Arguments:
1. "address" (string, required) The flo address to send to.
2. "amount" (numeric or string, required) The amount in " + CURRENCY_UNIT + " to send. eg 0.1
3. "comment" (string, optional) A comment used to store what the transaction is for.
   This is not part of the transaction, just kept in your wallet.
4. "comment_to" (string, optional) A comment to store the name of the person or organization
   to which you're sending the transaction. This is not part of the
   transaction, just kept in your wallet.
5. subtractfeefromamount (boolean, optional, default=false) The fee will be deducted from the amount being sent.
   The recipient will receive less flos than you enter in the amount field.
6. replaceable (boolean, optional) Allow this transaction to be replaced by a transaction with higher fees via BIP 125
7. conf_target (numeric, optional) Confirmation target (in blocks)
8. "estimate_mode" (string, optional, default=UNSET) The fee estimate mode, must be one of:
   "UNSET"
   "ECONOMICAL"
   "CONSERVATIVE"
9. floData (string, optional) Transaction floData (default = "").

Result:
"txid" (string) The transaction id.
