Ethereum là gì? Phần 5: Transaction và message trong ethereum -blockdev-

The provided transcript is unintelligible and appears to be a random collection of words and phrases in multiple languages. It's impossible to summarize it meaningfully regarding Ethereum transactions and messages. There is no coherent discussion of Ethereum, transactions, or messages within the text. Therefore, I cannot provide a summary in Vietnamese or any other language. The transcript needs to be corrected or replaced with a coherent and relevant text.
