Thank you for attending the lecture in Steemit-Crypto-Academy Season 3 & doing the homework task-3

Essentially from the perspective of a sender, all these transactions get combined into a single transaction.

In a network like Bitcoin it has inbuilt capabilities to send multiple outputs. In a network like Etherum you can code it (Smart contract capabilities) to multisend/batchsend to hundreds of addresses.

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

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

The beauty of Blockchain is that here the transaction fee is charged based on the transaction, not based on the outputs, that's how it gets cost-effective if you batchsend to a number of outputs.

One more advantage of using good dApps for this use-case is that there is hardly any chance of error on part of the wrong or invalid addresses or incorrect formatting.

That's true. But it still involves the risk of Address typos. An invalid address in the one that is not recognized by the Blockchain, but address typos could accidentally become a phishing account and a phishing account is a still a valid address for the Blockchain, hence for the dApp too.

However, we should learn to upload CSV as it's easier to handle large data when required.

That's correct.

So yeah, this tool will not send transactions to invalid addresses.

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.

In Steem Blockchain, we have witnessed numerous cases of phishing attempts.

For example, @huobi-pro is the actual/official Exchange account of Huobi Exchange, but due to address typo it could become @hubi-pro which is a phishing account to prey upon the address typos.

So @hubi-pro in this case is an incorrect address for a sender, but a valid address for Steem Blockchain. Therefore always be careful and attentive when you fill out the data in the Accounts Box using Steemyy.

Steemyy does allow the transaction to go through in the cases of a valid address(recognized by Steem Blockchain), but it does not allow it in the case of invalid addresses.

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 "Multisend" 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.
• You should put more effort to make it more appealing with proper formatting, emphasizing the text/screenshot.

Thank you.
