ПРОГРАМА:
Security is the most important thing in a smart contract. One mistake and the contract falls apart. Assuming that security is top notch, the second most important and often overlooked thing is usability. And usability in a system like Ethereum goes hand in hand with gas cost optimizations. A contract which is not optimized could make it cost prohibitive for many users. In some cases the contract can even become unusable if function calls use more gas than the currently available limit. In this lecture I will show with examples various gas cost optimization techniques. Even if you’re already familiar with gas cost optimizations, I think you’ll find some interesting tips in this lecture.

>>> Packing variables, function arguments and results;
>>> Pay attention to execution order – it can make a big difference;
>>> STORAGE and MEMORY and CALLDATA, oh my!
>>> Give me my gas back!
>>> Inline assembly tricks;
>>> Minimizing on-chain data;
>>> Live Example 1: Binary Logarithm (Finding index of most significant set bit);
>>> Live Example 2: Optimizing voting by using slots;

>>> Q&A;
>>> Networking част;
