Ethereum: Is there a full reference of Bitcoin with examples?
API Bitcoin is an important tool for programming interaction with the Bitcoin network and access to various data points. Although it provides a comprehensive interface for many tasks, some of his methods are poorly documented or difficult to find in the official Wiki. In this article, we will examine whether there is a full reference of Ethereum API with examples.
API Bitcoin
Before you immerse yourself in Ethereum API, we first realize what Bitcoin is. Bitcoin API (also known as Bitcoind API) is a set of commands tools that allow programmers to communicate with the bitcoin network. It allows access to different data points, such as condition, transactions and more.
API Bitcoin has increased significant changes over the years, but its basic functionality remains mainly the same. The current version of Bitcoin API (V2) is available for most operating systems, including Windows, MacOS and Linux.
Bitcoin integration by Ethereum
On the other hand, Ethereum is a decentralized blockchain platform that uses a different consensus algorithm than Bitcoin. Ethereum provides its own API set, known as Ethereum API or Web3JS, which allows programmers to interact with the Ethereum network.
Ethereum API (V2) is similar to API Bitcoin in terms of command line interface and data structure. However, it has some key differences, such as supporting various functions specific to Ethereum, such as intelligent contracts, decentralized applications (DAPP) and others.
Full reference Ethereum API
Although numerous internet resources are available containing the official API -Ji Ethereum, a comprehensive complete reference exists only in the Web3.Js. Documentation. Internet
Here is a high level of what you can expect in references to API Web3JS:
* Blockchain data : Web3.JS allows access to various data points related to data, such as blocks, number of transactions and others.
* Intelligent treaties : You can communicate with intelligent contracts using the Web3JS „ETH.Contract” or other methods such as „Web”
* Interactions of decentralized applications (DAPP)
: Web3.JS provides interface from DAPPS Online, including methods such as web3.eth.defaultprovider.
* Integration of service providers : You can at the same time use Web3JS to interact with many Web3 services.
Here is a code sample showing some of the key features of Ethereum API -Ji:
`Javascript
Const web3 = required ("web3");
Const Ethers = demand ("Ethers");
// connect to the Ethereum network
Const provider = new ethers.poviders.web3provider ();
Davigator.etblocknumber (0);
// get the height of the electric block
Const height = waiting for the supplier.GetblockNUMBER ();
// Communicate with an intelligent contract using the Web3JS 'ETH.CONTRACT'
Const Treaty = ethers.contract ('0x1234567890abcdef', {}, 'bin/0x1234567890abdef');
Treaty.methhods.addddalance (0, 10). Send ();
Application
Although some API Ethereum interfaces are well documented and easy to use, there is still a comprehensive complete reference in the Web3JS documentation. This provides programmers with an exhaustive guide of interaction with the Ethereum network.
By using the API WEB3.JS interfaces, you can access various dots of data related to blockchain, intelligent contract interactions, interaction of decentralized applications (DAPP) and others. Regardless of whether you build a new DAPP or communicate with the existing Ethereum network, a reference to API is an indispensable source for every programmer.
Examples of use cases
To start with, here are some examples of using the API WEB3JS interface:
* In interaction with intelligent contracts : use `ETH.
