Ethereum Smart Contract Development

Swarm

Until now, we have been treating the modules of swarm, whisper, and EVM as a black box, where we are only interested in how these modules interact, rather than what really happens inside them. However, to have a firm base for developing smart contracts, which we will eventually define and take up in Chapter 3, Hello World of Ethereum Smart Contract, we need to know the bare minimum internal workings of these modules. This will help us in tuning the smart contract code to make its performance better while running on the Ethereum blockchain.

So, how do we measure the performance of our code? The answer is unfortunately not very straightforward, but lies along several axes. Performance is measured along resource consumption, and code consumes ...
