Abstract

This draft TIP describes the usage of "fee" field in transaction

Motivation

Facilitating the flow of asset and values in TrueChain Networks

Specification

when the "fee" filed in transaction is not null, subtract amount of fee from sender account and add this amount to payment account.

Here is the new form transaction:

- AccountNonce: Number of transactions sent by the sender.
- GasPrice: Number of Wei to be paid per unit of gas for this transaction.
- GasLimit: Maximum amount of gas should be used for this transaction.
- Recipient: Address of the beneficiary for this transaction.
- Value: Amount of token to be transacted.
- Fee: Assert service charged.
- Data: Virtual machine code for smart contract deployment or miscellaneous use.
- Payer: The payer sender wants the transaction to be paid by.
- V,R,S: Cryptographic values corresponding to the signature of the transaction, and used to determine the sender of the transaction.
- PV,PR,PS: Cryptographic values corresponding to the signature of the payment, used to determine the payer of the transaction.

When EVM executes a transaction and Detected that Fee and Payer address is not empty,
will perform evm.StateDB.SubBalance(Sender, Fee) and evm.StateDB.AddBalance(Payer, Fee).
