A transaction is a data package to transfer ether from an account to another account or contract, invoke methods of a contract, or deploy a new contract. A transaction is using Elliptic Curve Digital Signature Algorithm (ECDSA), which is a digital signature algorithm based on ECC. A transaction contains a signature identifying the sender and proving their intention, the amount of ether to transfer, the maximum number of computational steps the transaction execution is allowed to take (called a gas limit), and the cost the sender of the transaction is willing to pay for each computational step (called the gas price). The product of the gas used and the gas price is called the transaction fees.
In permissioned networks, ether is valueless. In a Quorum network, ether is supplied in the genesis block and is not generated dynamically at runtime...
