Ethereum token game
a brief history of etheric Classics (etc)
etheric classics began with an unfortunate event
in May 2016, the decentralized autonomous organization (DAO) held a token sale with the goal of establishing a blockchain based venture capital to fund future decentralized applications (dapps) in the Ethereum ecosystem
basically, Dao is a complex smart contract that operates in a decentralized way - computer code that automatically performs tasks between multiple parties when conditions are met
despite its ambitious goals and successful token sales, Dao's code has a major vulnerability that allows attackers to steal eth from decentralized organizations
the attacker took advantage of this vulnerability in June 2016, triggering the infamous Dao hacking event, and maliciously stole eth worth about US $50 million
there is no doubt that Dao hacking has shocked Ethereum community and made eth price drop from $20 to $13
after the Dao hacking, the Ethereum community has to choose from three options
< UL >do nothing and try to bear the consequences of the attack; Or
start soft bifurcation to recover funds; Or
deploy a hard fork to recover the lost eth
both soft and hard bifurcations are significant network upgrades. However, soft fork allows users who are not upgraded to communicate with upgraded users, while hard fork is not backward compatible with previous versions
as developers realize that deploying soft forks will expose the network to distributed denial of service (DDoS) attacks, Ethereum community decides to initiate hard forks to recover the funds lost in Dao hacking attacks
although this scheme is supported by most people, a small number of people in Ethereum community oppose it. They think that "code is the law" and blockchain network should be unchangeable
the failure of both sides to reach an agreement on the solution eventually led to the fragmentation of Ethereum blockchain
those who tried to recover the lost eth chose the hard fork and opened the Ethereum (ETH) blockchain as we know it today, while another group stayed on the original Ethereum classic (etc) chain
what problems does ethereal classic solve
Ethernet classic (etc) is a blockchain platform that allows developers to deploy smart contracts and dapps
although this function is the same as Ethereum (ETH), etc blockchain has two main differences
first of all, Ethereum classic community opposes tampering with distributed ledger and supports the view that "blockchain network cannot and should not be modified"
secondly, although there is no rigid upper limit on the total supply of eth, it is allowed to create 230 million etc at most by adopting the monetary policy of constant supply
as a bonus item, ethereal classic launched Atlantis hard bifurcation last year to increase the interaction with Ethereum and improve the privacy protection of transactions through ZK snarks
the trading platforms recommended by etc
hot money, okex, AAX, etc
in order to create erc20 token, you need to write down the following contents
- token name
- token symbol
- token decimal
- number of tokens is in circulation
- Contract
- code verification source code
in addition to erc20, there are erc20, erc721, erc223, erc621, erc827, But for erc721, by the way, erc721 is a protocol mainly used for blockchain games. The blockchain games you often see are basically based on erc721
1. Why ATM? The ATM has three characteristics: first, it has money to withdraw continuously; Second, it can be taken out; Third, it is very convenient to store and take as you go. Take a look at the LW game. No matter when and where anyone joins, and no matter how much money you invest, from the second you join, you can participate in the dividend of all the people who enter behind you. As long as someone enters, the dividend will not stop. That is, there will be a steady stream of money; Second, Ethereum, the internationally recognized digital currency, can be cashed out at any time, so it takes out real gold and silver; Third, dividend settlement in seconds, not monthly settlement, weekly settlement and daily settlement, but second settlement and second withdrawal. If you want to re invest, you just need to move your finger, so it's very convenient to deposit and withdraw at any time. The above three characteristics determine that LW game is a member's ATM
2. Why permanent? LW game income has 4 items, one is to join that enjoy permanent continuous dividend; Second, at the end of the game, you can enjoy or divide up the bonus pool to get the bonus; The third is the probability of airdrop bonus every time you add or re cast; Fourth, the promotion takes 10% and 3% of the recommendation award of the second generation. The dividend and promotion award are deterministic income. As long as you join, you will get permanent dividend. As long as you promote, you will repeatedly take 10% and 3% of each additional investment and re investment. These two incomes are very considerable. Over time, it is very possible to earn 100, 100 or even 1000 times! Airdrop and bonus pool are probability events. It's hard to master them, but they always have opportunities! Because there is always a chance, there will always be people to play. Let's make an extreme assumption. Now the countdown is just a few seconds away, and it's about to end. At this time, only you and I are left to play. There are tens of millions or even hundreds of millions of prizes in the bonus pool. As long as you put in a minimum amount, such as one seed and 0.5 Ethereum, you have a 50% chance of winning the grand prize. Do you want to put in? Anyway, I will definitely vote, and I wish you didn't! I believe you also want to! So even if only you and I are left, we will fight until one falls down! What's more, when other people see this situation, there will be more people to join Boyi! Do you think this game will end easily? So in theory, LW game can never end once it starts! The game never ends, the dividend airdrop income will never stop, is it permanent card withdrawal
3. Will the amount of money withdrawn from the ATM change? Will dividend change? The answer is that it will change! At the beginning of the day, the dividend will be very high, because the number of people who follow in the short term will increase explosively, so it is normal that the number of people who join in the day will increase several times or more. Then the number of people who join in the day will change from explosive growth to steady growth, and the dividend will decrease significantly in the short term, but it will maintain at a relatively stable level when it drops to a certain extent, which will last for a long time. In addition, earnings are closely related to the rise and fall of Ethereum's price. If you encounter some events, the impact may also appear obvious fluctuations, explosive rise and fall are possible, but it will not end easily
4. When is the best time to join? The answer is: the earlier you join, the more appropriate it is. You can join at any time! The earlier you join, the cheaper the seed price is, the more seeds you can buy with the same investment, the larger the proportion of dividend expediency, and the more dividends you get! Because the game will be played for a long time, it's not too late to join at any time. There will be latecomers. As long as you want to do it, joining immediately at any time is the right choice
finally, four words for you:
LW platform game
withdrawal perpetual motion machine
the earth does not explode
withdrawal does not stop!
with Ethereum officially confirming erc-721 as one of the new token standards, many people are asking what erc-721 is recently. There are many technical posts on the Internet to analyze the code differences between erc-721 and erc-20. They are very unfriendly to Xiao and leek. With the attitude of sharing knowledge, I will try to explain the most significant differences between erc-721 and erc-20 with intuitive words
erc-20 standard token:
1
2. It can be subdivided into N parts (n = 10 ^ 18)
conclusion: similar to the currency in real life, it can perform all monetary functions. The application cases are similar to legal currency and virtual currency
erc-721 standard token:
1
2. The minimum unit is 1 and cannot be subdivided
summary: non homogeneity exists widely in life, such as art, pets, handicrafts, custom-made items, etc., and can even be used to mark students in schools, doctors and patients in hospitals, etc. The application scenarios are very wide
the above description is relatively concise. Taking a look at specific projects can help you better understand erc-721 standard. At present, the popular projects using erc-721 standard can take a look at
- cryptokitties (cryptokitties | collect and breed digital cats!)
this is the "ethereal cat" mentioned before. It's very basic and interesting. Each cat is a token with unique attributes. The more unique the attributes, the higher the value of the cat. It's very popular, but its development potential is limited
- 0xcert (0xcert - supporting uniformity.)
this project is a recent project of personal interest, which is close to life and easy to implement. Erc-721 token is used to mark real-life artwork or a unique item, and record the basic attributes, characteristics, value, previous owners, etc. It is very helpful in combating counterfeits and piracy. It may also be used in the second-hand market, exchange of valuables and other scenarios in the future
personally, I am very optimistic about erc-721 standard. After the whole blockchain instry calms down from the carnival, the implementation of the project has become the first consideration for developers, and erc-721 is very suitable for connecting the blockchain with the real world.
bitcoin, Ruitai coin, Laite coin, Ethereum and other digital cryptocurrencies all use blockchain technology
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain is a series of data blocks generated by cryptography, each of which contains the information of a bitcoin network transaction
