How to copy transaction ID of fire coin blockchain

1.

first, define the

blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain

Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network security

in the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent

In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees

ICO trading is roughly divided into two parts, one is OTC trading, the other is exchange trading. There are three ways to go to the exchange, the first is to vote on the currency, the second is to invest in the currency, and the third is to cooperate with the project party

for the exchange, the more platform coins consumed by voting, the better; For the project side, the lower the cost, the greater the impact of users, the better; But for ordinary social users, the easier it is, the better

What does the project party need to have

{rrrrrrr}

the cost of project docking with the exchange:

at present, the popular Matcha exchange generally has about 12-15 BTCs,

biki and gate exchange have about 10 BTCs,

ZG exchange has many choices when docking with 6-8 BTCs,

2-5 BTCs, such as Lein, ZBG, fcoin, WBF and so on

Fcoin, which is relatively cost-effective, is also a good choice. Later, the project parties can work together with the platform to do activities, whether it is airdrop, IEO or other can be discussed

3. This kind of digital currency platform may involve cross-border transactions, which is illegal in China. The state has been cracking down on it. Financial security has been raised to an unprecedented height. There is no guarantee for capital security on the platform. This kind of transaction is highly leveraged, which is actually the most difficult and difficult to make money. It is better for non professionals not to participate and try with their hard earned money, It's not so easy to make money. Don't listen to others; In any instry, the more you know, the more professional you will be able to earn. It's just that it's possible. This kind of leverage game has great mental pressure and is prone to various physical problems

4. There are still many blockchain trading platforms, such as coin an, fire coin, OK and so on, which are relatively large platforms
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money

in this example, Lao Wang and Xiao Li are two nodes

now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database

because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking

until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."

when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:

abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization

they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records

next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization

What if you try to bribe all the villagers? It's too expensive

the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules

a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
