Fish pond and mine pond can dig EOS

1. Due to the dpos consensus mechanism adopted by EOS, 21 super nodes need to be elected by voting, and every investor with EOS will have the right to vote on the super nodes, and voting is our only right in the EOS node election. We need to cherish and properly exercise this right, and jointly decide the best 21 super nodes to maintain the stable operation of the EOS system
of course, voting has no direct benefits, but if we choose excellent super nodes, and these super nodes will undertake to maintain the stable operation of the EOS system after winning. With the stable development of the EOS system, the EOS in our hands will be more and more valuable, which can be said to be the indirect benefits of this voting
block.one, the company that develops eos.io software, has said that they will only release one command-line tool of eos.io version 1.0, in which users can vote. This requires users to grab a section from GitHub code base and run it on their local computer. Some community members have created their own user-friendly interface through which users can vote. For example, the one-stop voting platform developed by huocoin mining pool can directly see the candidates of each super node and vote with EOS in the exchange. The other way is to vote through the way of voting agent, and give our voting right to the voting agent, so that the voting agent can vote instead of us.

EOS is a public chain system at the bottom of blockchain developed by block. One, which is specially designed to support decentralized application of Commerce, and its code is open source

bitcoin is called blockchain 1.0 because it opens up the world of digital cryptocurrency and takes a decisive step from 0 to 1

Ethereum is known as blockchain 2.0, because it provides Turing complete virtual machine that can run smart contracts, bringing unlimited possibilities

and EOS is called blockchain 3.0, why? Two words: performance

The positioning of EOS is the slogan of its home page:

English: the most powerful infrastructure for decentralized applications

Chinese: the most powerful decentralized application infrastructure

EOS expects to be an enhanced version of Ethereum, a high-throughput intelligent contract platform

although Ethereum has complete functions, it is limited by its design choice. Due to the block output speed of 15 seconds, the transaction throughput is far from large-scale practical level, which is only about 30 ~ 40tps (transaction / s). EOS, on the other hand, has chosen a different technology route, with the goal of achieving a considerable million TPS, which is quite attractive considering visa's actual processing speed of 1700tps

consensus mechanism of EOS

the reason why the throughput of bitcoin and Ethereum is so low is that they are constrained by the application scenario they envision and the consensus mechanism they choose for the scenario - both of them assume that the environment in which the system runs is totally untrustworthy, so they both adopt the consensus mechanism of proof of work

consensus, as the name suggests, is to reach a unified understanding of something - for blockchain, something refers to the confirmation of the transaction - any node to submit a transaction needs everyone's approval

the pow mechanism currently adopted by bitcoin and Ethereum is the design of the legendary Nakamoto Tsung. Under this mechanism, in order to obtain the bookkeeping right and digital currency reward, miners need to constantly dig for the compliant hash value, and confirm and package the transaction data through the consensus of hash value. POW has no access threshold, and any node has equal rights to participate in bookkeeping. Of course, the probability of winning is related to computing power:

the price of ram is based on Bancor algorithm, that is, it is regulated by market supply and demand: if the supply of ram exceeds the demand, more EOS certificates are needed to buy ram, At this time, more EOS certificates can be obtained by selling ram

memory is a consuming resource, which cannot be redeemed and can only be bought and sold. Take the issue of currency on EOS as an example. At present, the issue of currency requires 20m of memory. An EOS can buy 20KB. According to the current storage price, issuing a currency will consume 1000 EOS. This is the source of EOS memory consumption

Course Overview

this course is for friends who are interested in the development of EOS decentralized application. The course covers the core concepts of EOS DAPP development, the development and deployment of smart contracts, and how the front page interacts with EOS blockchain. Finally, a complete DAPP development based on react and EOS is completed

Chapter 1: enter the world of EOS

to understand the core concepts of EOS, such as positioning and characteristics, consensus mechanism, payment computing model, etc

Chapter 2: Hi EOS

understand the overall framework of EOS node software and the functions of node server, wallet server and command-line tools, learn how to configure and start EOS node server and wallet server, and preliminarily understand the use of command-line tools

Chapter 3: wallet, key and account

understand the three core concepts related to personal identity in EOS: wallet, key and account, and learn how to use command-line tools to create wallet, key and account

Chapter 4: development and interaction of smart contracts

understand the concept and function of smart contracts, learn how to write and compile EOS smart contracts, and learn how to deploy and interact with contracts using command-line tools

understand the persistence mechanism of state in EOS smart contract, and learn to use multi index table to save contract state

Chapter 5: issue your own tokens

learn the principle and implementation mechanism of issuing tokens on EOS, and master how to use command-line tools to issue, transfer and view the balance of tokens through practical operation

Chapter 6: use code to interact with smart contract

understand the principle of interaction between application and EOS blockchain, and learn to use JSON RPC interface and eosjs encapsulation library to access EOS blockchain

Chapter 7: DAPP development of practical notes

comprehensively use EOS knowledge, use react to complete a decentralized application of EOS notes, and learn the complete process from requirement analysis to code implementation

The above course address is as follows: EOS tutorial

3. EOS Digital currency online main network, but just online when there are many small problems

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband

extended data

users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

5. Grapefruit coins cannot be mined. Its circulation is now 1044440513eos. Now you have to go to the trading platform to buy the grapefruit coin
in fact, many currencies do not support mining. For example, gold, OMG coins and so on.

6. Before 18:00 on May 31, 2018, the EOS recharged to the fire coin platform will be mapped by fire coin, including the EOS transferred to the fire coin pool account.

9. You should know that if you don't have any real materials, you have to submit six materials. So it's really rare to be able to stand out as a hexathlon.
