Etherscan(https://etherscan.io) among other block explorers is one of the important pieces of a blockchain application that allows us to analyze the data in the blockchain. In this workshop, we will welcome Jeff Wentworth of Curvegrid to build a toy version of Etherscan.
The programming language used will be Go (https://golang.org/), with a small amount of HTML and Solidity. However, those familiar with other C-like languages should be able to follow along.
If you like, you can familiarize yourself with Go and a couple of key blockchain concepts ahead of time:
- A Tour of Go (English: https://tour.golang.org/welcome/1) (日本語:https://go-tour-jp.appspot.com/welcome/1)
- ERC-20 crypto token standard (https://theethereum.wiki/w/index.php/ERC20_Token_Standard)
- Ethereum transaction events, English option: Technical Introduction to Events and Logs in Ethereum (https://media.consensys.net/technical-introduction-to-events-and-logs-in-ethereum-a074d65dd61e)
- Ethereum transaction events, 日本語: https://qiita.com/blueplanet/items/460f562235019a1bb07d
*Beware that this is the hands on programming event. Bring your laptop with you. You will have the free access to our Wi-Fi at the venue.
