different blockchain communities on this platform, each of which is committed to developing one or more projects, but unfortunately, many projects have a high failure rate. Of all blockchain-related projects on GitHub, only 8% is currently active (at least once in the last six months). The organization-led project (15% still being maintained) is better than the user-led project (7% is still active). 20 Center code base for blockchain ecosystem According to the latest statistics, there are an e

I'm sure everyone has heard that the headlines about DAO theft up to $150m are exploited by hackers using recursive ethereum to send exploits.

Preface This is a teaching article, mainly for understanding the Ethernet square and block chain technology used. It was a technical curiosity to write this article. Block-chain technology began to use virtual currency, in which Ben Cong started the bitcoin block chain in January 2009. Bitcoin was born, through several rising prices let block chain technology is famous. Block chain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, co

Here are three ways to install Geth: Direct download executable file online install from source code compile installation method a direct download executable file The simplest way is to download the executable file directly, the Etheric Square develop

Although Bitcoin (Bitcoin) and Ether Square (ethereum) are two words that are often mentioned together, there is a big difference between bitcoin and the etheric square. The only thing they have in common is that the ether is also a cryptographic asset running on a block chain. Unlike Bitcoin, which is only a cryptographic currency, there are many other features in the etheric square. It is these characteristics that make the etheric square a centrali
