bro it is the best video about data structure in ethereum, thank you very much!! finally the puzzle is complete!

[@Naz-yi9bs]

Amazing explanation, thank you so much. Question, @24.50 you mentioned that if someone or you deploy a contract to the EVM and if both have the same hash only one will be kept on the Ethereum blockchain? Can you explain this a little more, thank you.

21:26 - block details

[@Never-re5lt]

Thank you!

@6:10 the [ ] are missing for the bytes _proof

[@seandarcy2612]

This is so good!

[@DevrajSinghRawat]

Question at @6:14
to prove TRIE , why do we need three proofs, Can we prove the TRIE with only two additional Merkle proofs
- 0xded..a4a
- 0x331...DCA

[@omarkhazamov]

👍👍

[@cryptopat2214]

Do you have a discord group?

[@shafu0x]

@9:10 so you only have to store the merkle root in the contract. Wow this is super clever.

[@DevrajSinghRawat]

@shafu.. Can you explain your statement, I could observe the merkleRoot was stored at Line3 but Did not completly understood why this appraoch is super clever?

[@shafu0x]

@@DevrajSinghRawat its like a compression of the whole thing. You do not have to store the whole merkle tree on-chain but only the root.
