As trend of privacy protection and trustless collabration is unstoppable in decentralized protocol, zk-proof is going to be widely implemented as technological infrastructure in blockchain network. Even though academic research in this space is booming, there is a huge gap for those working in crypto industry to both understand zk-proof theoretically and apply it appropriately. After researching into it diligently with abundant experience as a blockchain developer, I decided to write a series of articles of which theme is mainly tutoring beginners with underlying machanism and implemented examples of zk-proof.

以太坊上存储256 bit数据大约消耗20k Gas、如此换算,仅1 GB存储资源要花费32,000ETH,按2021年12月14日ETH价格,大约要花费超过1亿美元。且不说当前身为贵族链Gas费很有可能继续水涨船高,放在早些年其Gas消耗也不是一笔小数目。因此,以太坊Gas优化是Dapp开发一直难绕的问题,也是Solidity开发者From Zero To Senior的必修之技。本文从我最近半年的以太坊项目开发的实战经验出发,从2个维度归纳了Gas优化的trick。
