As you may see on this link of pending transactions https://etherscan.io/txsPending
You may see that there is a list of pending transactions. If you select one of them you will see the following
Somehow, I thought that the 'from' should not be here based on my reading of "Mastering Ethereum Building Smart Contracts and DApps" where it says clearly that
there is no “from” data in the address identifying the originator EOA. That is because the EOA’s public key can be derived from the v,r,s components of the ECDSA signature.
I thought that the transaction is transmitted through the network with RLP-encoding but it seems I am mistaken and there is a Transaction Hash which (please correct me if I am mistaken) is the keecak-256 hash of the RLP-encoded tx. Is this how the contract is transmitted through the network?
I understand that the data are stored in ethereum within the block as the Merkle trie root as described here.
If you please help me understand this as I am really struggling to get my head around this!
