Hi @yorma

Thank you for joining The Steemit Crypto Academy Courses and participated in the Homework Task.

Presentation| 0.5/2
Consistency, Compliance with Topic| 2/2
Quality of Analysis| 1/2
Real Transactions| 2/2
Originality| 2/2
Total| 7.5/10

Observation/Suggestion/Feedback:-

• The author has demonstrated(with a real transaction) "how to send different amounts to different users with different memos" & "how to send repetitive transfer at a predefined interval at one click" using Steemyy with all the screenshots included.
• The author has also demonstrated how to batch send using the "Multisender" app in Etherum Blockchain with all the relevant screenshots included.
• Demonstrating a use-case with real-world application/necessity will make the presentation more creative and it would make us feel more real & useful, that way you will also score better.
• One round of proof-reading is still required.
• Proper formatting is needed to make the presentation more professional.

You did well but still, some below are important notes which you could try in a better way.

(1) How does it(multisend) save transaction fees?

There are two components:-

• Transaction
• Output

There can be a single transaction, with a single output(destination address)

There can be a single transaction with multiple outputs(destination addresses)

In both cases the transaction fees would be more or less the same(although the exact figures vary depending on the network and fee calculation). So the point to note here is that the fee is charged based on the transaction, not based on the output. That is why batch-sending to hundreds of outputs becomes cost-effective.

(2) Quality Analysis of Wrong Address/Invalid Address

You did this well but still there is a difference between invalid and incorrect/wrong addresses.

What is wrong for you may not be wrong for the Blockchain always, and always remember, what is valid for the Blockchain is always valid for the application/tool(Steemyy).

An invalid address is not recognized by the blockchain. In Steem Blockchain, you can say this username does not exist or is not created yet.

An incorrect address(Possibly a Steem Address typo) may still be a valid address, but may not be the address you intend to make a transfer to, and in that case, you might end up losing your fund.

Your Homework Task verification has been done by @Stream4u, hope you have enjoyed and learned something new.

Thank You.
