Data and contracts on the Ethereum network are encoded, but not encrypted. Everyone can review the behavior of the contract and the data sent to

===================================
Ethereum's goal is to build a centralized platform for running smart contracts based on blockchain technology.
# # One. Blockchain technology
Blockchain belongs to a kind of centralized digital bookkeeping technology, and blockchain data is maintained by nodes that are not trusted by each other, and each node replicates a complete record.

: when you add a $100,000 currency to the pool, it is all sent to the recipient. Or, if the threshold of $100,000 is not reached within one months, all currencies will be sent back to the original holder of the currency. This, of course, will use the etheric currency instead of the dollar. All of this will be done according to the smart contract code, where the smart contract code automates the transaction without the need for a trusted third party to
Preface
Since go Ethereum is the most widely used Ethereum client, subsequent source analysis is analyzed from this code on GitHub.

Account
The account plays a central role in Ethereum. There are two types of accounts: external accounts (EOAS) and contract accounts. We'll focus on the external account here, which will be referred to as the account. Contract accounts are referred to as contracts and are discussed specifically in the contract chapters. The general concept of putting both external and contractual accounts into accounts is justified, since these entities are so-calle
Ethereum History
For recent history, please see the Taylor gerring blog post. Birth
At the same time, Vitalik began working with Dr. Gavin Wood to create Ethereum. In April 2014, Gavin published the Ethereum Yellow Book as a technical note for Ethereum virtual machines. As specified in the Yellow Book, the

Article, where the information may have evolved or changed.
After learning from various sources, we decided to start building a private chain environment based on Ethereum Go-ethereum. Because my computer system for WIN8, in order to avoid the window environment too many inexplicable problems, deliberately through the VM built a ubuntu16.04 version of the virtual system. The following
In doing some testing, it may be necessary to build a private ethereum network to facilitate control and to get to the real test work faster.While the Ethereum nodes can link to each other need to meet 1) the same protocol version 2) the same networkid, so the most convenient way to build a private network is to use the--networkid option in the Geth command to set a different networkid from the main network
In Ethereum (1): In the steps to build the Ethereum private chain on CentOS 6.5 we set up the Ethereum private chain, this time we will create accounts, mining and transfer operations in this private chain environment.
First of all, to review the construction process, the more important part of our talk.
We used the last step in the build./geth--rpc--rpccorsdoma
This article is mainly a supplement to the previous article, before the operation, we need to prepare two computers with an ethereum environment. Suggest learning Ethereum or other blockchain project preferred Linux or Mac OS, personally feel that CMD is not easy to use, because I have another window system on the computer, so I was on the window to recompile the Ethere

To honor the Ethereum security requirements, we need to choose the minimum chain length N (below which we veriy every head ER) and Maximum K verification batch size such as (1/k) ^ (n/k) We define the probability that the negligible probability PN is to obtain a 256-bit SHA3
