How to play forsage Ethereum smart contract

3. Smart contract & quot The term "smart contract" can be traced back to at least 1995 and was proposed by the prolific interdisciplinary legal scholar Nick Szabo. He mentioned the concept of smart contract in several articles published on his website. His definition is as follows:
& quot; A smart contract is a set of promises defined in digital form, including the agreements on which the contract participants can execute these promises& quot;
let's explore the meaning of his definition in more detail
commitment
a set of commitments refers to the (often mutual) rights and obligations agreed by contract participants. These commitments define the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods and the buyer promises to pay a reasonable price
digital form
digital form means that contracts have to be written into computer-readable code. This is necessary, because as long as the participants reach an agreement, the rights and obligations of smart contract establishment are executed by a computer or computer network
to further explain:
(1) when will the parties to the smart contract reach an agreement? The answer depends on the specific smart contract implementation. Generally speaking, the contract is discovered when the parties are committed to the execution of the contract by installing the contract on the contract host platform< (2) contract execution
& quot; Execute & quot; And the real meaning of it also depends on implementation. Generally speaking, implementation means active implementation through technical means
(3) computer readable code
in addition, the contract needs specific & quot; Digital form & quot; Very much depends on the agreement that the parties agree to use
protocol
protocol is technical implementation, on this basis, the contract commitment is realized, or the contract commitment is recorded. Which agreement to choose depends on many factors, the most important of which is the nature of the assets being traded ring the performance of the contract
take the sales contract as an example. Suppose that the participants agree to pay in bitcoin. The chosen protocol will obviously be bitcoin protocol, on which the smart contract will be implemented. Therefore, the contract must use & quot; Digital form & quot; It's bitcoin scripting language. Bitcoin scripting language is a non Turing complete, imperative, stack based programming language, similar to forth.

The smart contract has been written for a long time

if they can add changes, the description is centralized

the contract is written into the Ethereum smart contract, which is a contradiction sentence

the financial customer service doesn't understand, which is very unreliable

5. Ethereum is not a scam, but there are countless scams designed by criminals around Ethereum. The best way to avoid Ethereum scams is not to trust the guaranteed return on investment and manage your own money bag. Choose a formal digital currency exchange to invest. At present, the mainstream digital currency transactions in the market are all coin security, fire coin network, bitnet, etc.

6. Etheric clown, cryptotown is my real name. Make a real blockchain pet development game, officially open the internal test today
as a pet that people love, what other characteristics do I have besides "beauty"
every day, I will act coquetry with my host
when I am full, I will work to earn money, eat less and earn more
for me, it doesn't cost the owner money, but also makes money (male clown)
I have a baby who is not out of shape. When the baby grows up, it can make money. When the baby grows up, it can make money again. There are endless generations (female clowns)
I carry 54 gene codes (well, several pairs more than 23 pairs of the host), engraved with genes given by my grandparents and parents, and my own random genes, which determine my appearance: background color, clothing pattern, skin pattern. Occasionally, there may be gene mutation to obtain some extremely rare appearance. Anyway, I'm unique
I am a digital collector, which is my most typical and important feature. I am a non-standard digital currency (like ethereal currency, each unit is equivalent, we call it standard digital currency). Each of our brothers and sisters represents the value of a currency, and with the owner's careful photos, the value will be higher and higher. If the owner has a new lover, he can sell me at any time to make money. Oh, I swear I won't count the money for you, Really
I, based on the blockchain, can never be changed: all my actions above will be recorded on Ethereum, and the host can clearly query all the above data information of me and my partners through the verification of the third-party platform. The gentleman is frank, that's us. Our smart contract part of the code, are open source Oh, owners can view any
next, let me give a brief introction to the play of cryptoclones
cryptoclones is a digital and collectable blockchain game based on Ethereum blockchain. Using ether money to adopt clowns can be resold, and they can also be used to breed a new generation of clowns with strange shapes. They can also be cultivated to work and earn money, which makes the digital collection of clowns more sustainable and playable<

1. The proction of clowns
the proction mechanism of clowns can be divided into two kinds, one is the official output, the other is the breeding output between two clowns
one official clown is proced every 15 minutes, and the total number is only 50000. At certain times, the official will also release some strange clowns with special shapes. The price of the original clown is the average of the prices of the last five clowns in the market
two clowns of different genders can reproce in the breeding center of the market. In each breeding pair, one clown who plays the role of father can receive the breeding fee paid by the other party (maternal Master). After breeding, there is a certain recovery period, which is related to the clown's genes. The clown in the role of mother will have a period of pregnancy, and she will not be able to breed with other clowns until she gives birth to her baby. There is no limit to the number of breeding times of each etheric clown, but the recovery period and pregnancy period will increase with the number of breeding times

2. The appearance of a clown
the appearance of every clown is determined by the tamperable genes stored in the smart contract, and each gene is unique, so every clown is unique
the appearance of a clown is composed of eight parts, each part of which can be divided into ordinary and rare attributes. The number of rare attributes is less than that of ordinary attributes, which makes the clown with rare attributes more precious
the appearance of a clown born in breeding is closely related to his parents and the genetic genes carried by his parents. The offspring have a high probability of inheriting the shape of some parts of his parents, so that their parents' good genes can be inherited, and it is possible to mutate and become a completely different clown from his parents

3. Clown trading
etheric clown can be used to trade directly
sell: users can choose clowns to be auctioned in the market, and they can sell their own clowns. When selling, users need to set the highest starting price, the lowest acceptance price and the auction time. The Dutch auction is adopted in the auction. During the auction time, the highest price set by the seller is graally transferred to the lowest price. If the owner is not willing to sell at a low price, a longer auction time can be set or the clown can be sold off the shelves
buy: the buyer selects the clown on sale in the market and pays ether to buy the clown he likes. When the buyer purchases, the transaction will be concluded at the auction price at the current time point. If you have a favorite clown, but feel that the price is not suitable for the time being, and want to pay more attention, you can collect the clown after you like it. Later, we can understand the dynamic of the clown through "my attention"<

4. Clown attribute and working
there are four kinds of clown attribute values: growth value, strength value, agility value and wisdom value. Generation 0 clowns get the value of each attribute randomly, and the non generation 0 clowns are mainly inherited
attribute values can be changed by eating food
after the clown's growth value reaches the requirement (100 points), he can go to the factory to earn money (ETH). Different kinds of factories need different clowns. Dream college needs the wisdom of every working clown. Clowns with more than 800 points of wisdom go to Dream Academy of Sciences to work, and their income can get bonus. If a clown with less than 300 wisdom goes to work, his income will be reced to
a part-time job will consume physical strength. The total physical strength is 120 points. It consumes 1 point every 12 minutes and can work up to 24 hours. During the period of not working, physical strength can be recovered, a little every 8 minutes
when the time reaches 0 o'clock or the clown's physical exertion is completed, the clown's work income will be settled according to the actual working hours at 0 o'clock every day. When every 12 minutes is a work, less than 12 minutes will not be counted

5. Clown food and feeding
owners can buy spinach, beef, carrots, walnuts and other food through the mall to feed clown pets
the price of food is related to the selling price of original clowns on the platform the day before. So the owners can hoard some food when the price of food is low
feeding spinach is helpful to growth value, beef corresponds to clown pet's strength value, carrot corresponds to agility, walnut corresponds to wisdom
the clown can only eat one food a day. We suggest that spinach should be fed in the early stage to meet the working conditions as soon as possible, and then according to the natural properties of clown in the later stage. When working, choose the type of factory with the highest attributes to work<

6. It's more lovely to bask in the sun.
it's OK. Go to the square and have a look. Here gathered a lot of lovely owners and clowns, if you adopt a very ugly cute clown, also bask in, let everyone know our style.

7. General banks can exchange, but limited to Monday to Friday, I suggest you can go to Bank of China and Bank of communications, especially Bank of China, this business is very perfect, you can also use RMB to exchange US dollars in the future.

8. No, blockchain is a decentralized distributed ledger. You can understand blockchain as Internet. Will Internet cheat people? No, but some people will use the Internet to cheat others, and blockchain is the same
blockchain is not only about issuing money, but also can be applied in many places. The biggest feature of blockchain is decentralization. General Internet procts are centralized, and blockchain can use decentralization to solve the trust problem between each node. Because in the blockchain, information is traceable and cannot be tampered with
now there are many blockchain landing projects. You can properly understand that it is not a simple coin issuing thing, nor a deceptive project.
