APIs, tools, and DApps
The Web3 JavaScript API provides an interface to the Ethereum blockchain via JavaScript. It provides an object called web3
, which contains other objects that expose different methods to support interaction with the blockchain. This API covers methods related to administration of the blockchain, debugging, account-related operations, supporting protocol methods for Whisper, as well as storage and other network-related operations.
This API will be discussed in detail in the next chapter, Chapter 13, Ethereum Development Environment, where we will see how to interact with the Ethereum blockchain with it.
Applications (DApps and DAOs) developed on Ethereum
There are various implementations of DAOs and smart contracts in Ethereum, most notably, the DAO, which was recently misused due to a weakness in the code and required a hard fork for funds to be recovered that had been syphoned out by the attackers. The DAO was created to serve as a decentralized...
