Network Status Monitoring
Ethereum (centralised) network status monitor (sometimes referred to as "Eth-netstats") is a network-based application that monitors the health of testnet/mainnet through a set of nodes. Checklist
To list your nodes, you must install the client information relay, a node module. The instructions given here work on Ubuntu (Mac OS x follows the same instructions, but sudo may not be necessary). Other platforms are also differen

Tokens are the way in which values are defined in a blockchain to demarcate financial or digital assets. In Ethereum, tokens use the same standards, which makes it easy to exchange and DAPP support between tokens. What is the ERC20 standard
The ERC-20 standard, introduced in November 2015, uses tokens of this rule to show a common and predictable approach. Simply put, any ERC-20 token can be immediately compatible with

In my study of Ethereum technology, because of less relevant information, so took more detours. So here we will not introduce the grammatical structure of solidity, but will be in the next stage, from the actual combat, in succession to introduce Geth, browser-solidity, mist these three tools, and in the process of constantly explaining the basic concept of ethereum.
Through the practical use of these tools
