Can the blockchain contract address be transferred out

1. There are many applications that have been implemented in blockchain. Although they can not be adapted to all application scenarios, there are many applications on the market, such as micro three cloud. Their blockchain integral system has many application scenarios such as e-commerce and content payment, and has been certified by many businesses.
2. From a technical point of view, smart contracts are considered to be network servers, but these servers are not set up on the Internet using IP addresses, but on the blockchain (chain Nova). So that you can run specific contract programs on it. But unlike web servers, smart contracts can be seen by everyone, because the code and state of these smart contracts are on the blockchain (assuming that the blockchain is public). Moreover, unlike web servers, smart contracts do not rely on a specific hardware device. In fact, the code of smart contracts is executed by all devices involved in mining (this also means that the computing power to enter a single contract is limited, although the automatic adjustment of mining difficulty will adjust this effect). Smart contract is an assembly language programmed on blockchain. Usually people don't write stanza code by themselves, but they compile it from a higher-level language, such as solid, a special language similar to JavaScript. These bytecodes do provide guidance for the functionality of the blockchain, so the code can easily interact with it, such as transferring cryptography currency and recording events. The execution of the code is automatic: either it is successfully executed, or all state changes are revoked (including the information that has been sent or received from the current failed contract) This is very important because it avoids partial execution of the contract.
3. The issue of bitcoin is determined by the block height, that is, the distance from the No. 0 block of Genesis. Now when the number is reached, the total amount of bitcoin should be limited. After this village, there will be no store. If the miners dig a block but don't receive the reward of the block, the bitcoin will be destroyed forever

coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)

however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them

therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently

in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number

as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.

therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin

it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards

generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed

if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns

there are only some special circumstances that require intentional destruction of coins

one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH

the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /

and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29

the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen

compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in

strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain

it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin

however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block
4. This thing in the block chain, if you want to sell it, you can sell the thing inside and sell it directly after the exchange, but only support the Alipay transaction.
5.

1. Learning conditions:

level above 45, each player can only learn two life skills at the same time. If you reach level 90, you should be able to learn the third life skill

6.

The address itself is anonymous. Ordinary people can't find it. But if you register with the exchange, the exchange has your information and blockchain address

anonymity and traceability of blockchain addresses : anyone can easily generate a large number of private keys, public keys and addresses. The address itself is anonymous, which can be further improved by multiple address transactions. But all transactions are transparent, that is to say, all transactions at one address can be checked and traced. That is to say, I can track and query all the in and out accounts and balances at the address you give

please refer to the webpage link for details

7. It must be supported. Okex not only supports the perpetual contract and delivery contract, but also supports the peak option contract of current contract trading. You can give it a try by exchanging limited risks for unlimited returns. Your adoption is my motivation
8. You have too many questions to answer here

the handling charge is a discount, not a refund. I have the impression that the contract is up to ten times

you can buy stable bitcoin, usdt usdk and then bitcoin

blockchain is a distributed decentralized account book

for example, the current bank data is managed by itself, and programmers can tamper with it

if blockchain technology is used, data can be saved by many computers and recorded separately. It can't be tampered with.
9. Already have, also held a million cash grand prize contest activities. At present, we support the firm offer of usdt delivery contract and have launched the simulation offer permanently
10. It's a hundred second card zone, right? I personally think that level 22, I suggest you go to
Fengmo Valley
inside
fight zombies
pick up
gold coins
(it's far away from the Earth City
Shabak
, a little less than the mine holes of
poisonous snake Valley
,
beech
), Or go to the cow of
cangyue
Island
to fight the cow devil sacrifice and
cow devil
General
, and someone has played out
Red Moon
equipment. You can also go to the Earth City
Zuma Temple
4th floor to fight
hornfly
bundle
back to the city roll
sell to players for gold coins. You can go deep, but most of them are
guilds, which are very easy to be killed.
