Ethereum: How are funds verified?

Ethereum: Foundation Approval Process

On the Ethereum network, verification of funds is critical to ensure that transactions are valid and that the sender of the transaction has sufficient funds to pay for them. This process involves multiple layers of checks and balances to prevent malicious actors from tampering with the system.

Mempool

Mempool is a critical component of the Ethereum network and is responsible for storing pending transactions waiting to be mined. Each time a transaction enters memory, a “block” is created in the system, allowing other miners to verify and confirm the transaction.

Miner Verification Process

When a miner wants to create a new block, they must first retrieve the latest mempool data from the Ethereum mainnet. This includes a list of pending transactions, the addresses associated with them, and the funds available for each address.

To ensure that the sender has sufficient funds, the miner performs two checks:

• Funds availability check: The miner checks if the sender’s wallet has enough Ether (ETH) to pay for the transaction.

• Signature verification: Miner ensures that the transaction signature is valid and correctly signed by the sender.

Smart contract approval

If funds are available, the miner confirms the transaction using smart contracts. These agreements confirm:

• Transaction identity

  

  : The contract verifies that the transaction matches the intended recipient and has the correct address.

• Gas limits: The contract confirms that the transaction’s gas limits are sufficient for execution.

Block production

Once all transactions have been verified during mining, a new block is created in the mempool, combining the confirmed transactions into a single block. This block is then transmitted to other miners on the network, who can use this information to verify and confirm subsequent transactions.

To summarize, the process of funds verification on Ethereum involves a number of checks and balances to ensure that transactions are valid and that the sender has sufficient funds to pay for them. Mempool plays an important role in storing and verifying the validity of pending transactions, while smart contract validation ensures the integrity of these transactions.
