create blockchain

With the "Subversion storm" caused by the blockchain, a large number of blockchain training institutions emerged. But in a mixed-up training circle, it is bucket to find a truly standard course system and a dedicated professional lecturer in the Blockchain field. Brother even education pointed out that it is time to make action to change and subvert the tradition

After more than 10 years of development, go language has become the most popular emerging language. At present,go language has become the preferred language in cloud computing, and with the popularity of blockchain in recent years, as the bottom of the development of the language go again hot become the Blockchain technology training field first programming language, IBM's fabic and other heavyweight

This article is from: "Blockchain technical Guide" section, hereby explained. Hash algorithm Defined Hash (hash or hashing) algorithms are very basic and very important technologies in the field of information technology. It can map any length of binary value (plaintext) to a shorter fixed-length binary value (hash value), and different plaintext is difficult to map to the same hash value. For example, the MD5 hash value for a paragraph "Hello

How the development zone block chain such topics, in the modern society still has been promoted, because the blockchain itself can be based on the actual needs of marketization, assets and personnel of the actual situation, to make accurate arrangements and transaction records of the non-discriminatory application form. Therefore, in the modern social field, in order to develop the first need to find the correct direction in the positioning, is to ens

Ethereum is the best programming platform in the area of blockchain development, and truffle is the most popular development framework of Ethereum (Ethereum), which is the reason why our first blockchain technology article introduces truffle, the actual combat is the most important thing, this article does not speak the principle, only build the environment, Run the first

Ledger structure: consensus mechanism: proof of workload mechanism (Proof of work) Other proof mechanisms: In the Bitcoin blockchain, when a transaction is generated through a node or purse, the transaction needs to be transmitted to other nodes for verification. The practice is to encrypt the transaction data through a digital signature and derive a string representing the unique hash value of the transaction via a hash function, and th

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, as well as the basic concept of ethereum to deepen understanding, for the second stage o

Merkle root. A simple workaround is defined in certificate transparency: When calculating the hash of a leaf node, add 0x00 before the hash data. When calculating the internal node is, precede with 0x01. Other implementations limit the root of a hash tree by prefixing the hash value with a depth prefix. Therefore, each step of the prefix is reduced, and the extracted hash chain is defined as valid only if the prefix is still positive when the leaf is reached. operation of the Merkle tree 1.

step of the prefix is reduced, and the extracted hash chain is defined as valid only if the prefix is still positive when the leaf is reached. operation of the Merkle tree 1. Create Merckle Tree There are 9 data blocks at the bottom of the join. Step1: (red line) hash the data block, node0i = hash (data0i), i=1,2,..., 9 Step2: (Orange Line) adjacent to two hash blocks in series, then do hash operation, Node1 ((i+1)/2) = hash (node0i+node0 (i+1)), i=1
