Introduction to interest causes touch the hot block chain field and tidy up the concept.

I start with the concept of a hash function
f (x) = y
A function that accepts input values, a hash function that requires input data/numbers/files to output a hash value that is typically 16 binary

The hash function is not reversible and cannot be determined by the output unless subjected to a brute force attack (try all possible inputs)

This is about the blockchain encryption algorithm below.

Blockchain concepts
    1. A decentralized, distributed ledger database in which each node of the data store is assigned the entire ledger synchronously
    2. Helps multiple nodes reach a consensus to record things related to tokens
    3. Can help everyone to build their own small economic system without barriers
Blockchain features

Non-tamper, anonymity, centrality, openness, consensus mechanism

Blockchain target (problem solving)

Aim to improve system efficiency and reduce credit costs

    1. Reduce business transaction costs and credit costs (distributed ledger database)
    2. Anti-counterfeiting technology (non-tamper)
    3. Strong assistance capacity (consensus mechanism)
The scope of blockchain technology

cryptography, algorithms, distributed systems, payment and trading technologies

Blockchain Technology Core

1. Block + Chain

Block + chain-formed database

2. Distributed structure

Open-source, decentralized protocols to build a distributed architecture system that enables value-exchange information to be released throughout the network,

The data content is determined by distributed bookkeeping, and the time stamp is built to generate chunk data for distributed storage.

3. Asymmetric Encryption algorithm

Two passwords with asymmetric features are used in [encrypt] and [decrypt]

4. Scripts

A programmable smart contract that enables the system to deal with unforeseen trading patterns

Blockchain Learning Knowledge

1, Blockchain basic knowledge and key technology analysis

Public key, private key, transaction, block, peer-network, mining (accounting rights), consensus mechanism, etc.

2. Hyperledger Fabric Architecture Learning

Enterprise Blockchain framework that focuses on modularity and scalability to support frequently changing business rules

3, solidity ether Square intelligent Contract development
