In Ethereum JSON-RPC I found the return is:

Returns

Object - A transaction object, or null when no transaction was found:
hash: DATA, 32 Bytes - hash of the transaction.
nonce: QUANTITY - the number of transactions made by the sender prior to this one.
blockHash: DATA, 32 Bytes - hash of the block where this transaction was in. null when its pending.
blockNumber: QUANTITY - block number where this transaction was in. null when its pending.
transactionIndex: QUANTITY - integer of the transactions index position in the block. null when its pending.
from: DATA, 20 Bytes - address of the sender.
to: DATA, 20 Bytes - address of the receiver. null when its a contract creation transaction.
value: QUANTITY - value transferred in Wei.
gasPrice: QUANTITY - gas price provided by the sender in Wei.
gas: QUANTITY - gas provided by the sender.
input: DATA - the data send along with the transaction.

But I type the command, the result is not same with the document above :

What does r, s, v and others mean ?

And value: QUANTITY - value transferred in Wei, what does it mean?

v, r, s are the values for the transaction's signature. They can be used as in Get public key of any ethereum account

A little more information, r and s are outputs of an ECDSA signature, and v is the recovery id. https://bitcoin.stackexchange.com/questions/38351/ecdsa-v-r-s-what-is-v also applies to Ethereum. For replay attack prevention, Ethereum makes further adjustments to v as explained in EIP 155.

value is how many Wei was sent to the to address. 1 ETH is 10^18 wei.

QUANTITY basically means that the value is encoded in hex.

  • Why there are 27,28,189,190 values? trying to understand it. esp 189 and 190 – rstormsf May 16 '18 at 16:11
  • @rstormsf Asking at https://crypto.stackexchange.com could be better. – eth May 20 '18 at 09:53

    I figured it out, it is result of applied chain_id number vs non-applied – rstormsf May 23 '18 at 22:51
  • Is it possible to have any abuse by having r, v, s? In terms of security. – Nabi K.A.Z. May 12 '22 at 17:25

    @NabiK.A.Z. Not sure what you mean, r, v, s, are specific to a transaction (and nonce), so using r, v, s on another transaction will almost always have an invalid effect. Replay attacks are a related area that you might be asking more about. – eth May 25 '22 at 04:06
  • @eth Of course, I did not mean merely repeating the transaction, in general, any security issues. For example, forging a signature, signing a new transaction, security code, wallet identity information, or any other security issue. – Nabi K.A.Z. May 26 '22 at 13:27

    @NabiK.A.Z. Maybe these answers will help? https://bitcoin.stackexchange.com/questions/111260/why-is-it-not-possible-to-get-the-private-key-out-of-the-public-key or https://bitcoin.stackexchange.com/questions/54857/does-signing-message-weakens-the-address-security – eth Jun 02 '22 at 05:18
