Digital currency blockchain technology system maintenance
Here you need to understand the correct digital currency issuance process, which is roughly divided into eight steps:
the first step is to build a digital token system
this is very simple. The code of bitcoin is public, and it is a kind of counterfeit currency after simple change; Ethereum's technology is open source. You can find a program to issue a coin on Ethereum's public chain. Now most of the counterfeit coins are on the public chain of Ethereum, and the distribution of tokens is also directly in Ethereum's wallet, which is very convenient
Step 2: find someone to endorse
if the project can be implemented, you may find a real influential tycoon, and by the way, you can take an angel wheel to do marketing. If the project is air money, it may be a grassroots tycoon. In any case, now that the coin circle is just emerging, many "tycoons" are actually grassroots. If you can't, you can send candy directly by virus marketing
Step 3: prepare a white paper
this has to be written on the top. For high-quality coin, vision, code, planning, team and so on need to be well written, which takes a lot of time. But for air coin, it's OK to find a professional agent directly, and it can be written in one day
The fourth step is to promote marketingfind all kinds of coin circle media to advertise, or get a virus activity to invite candy delivery, and brush the popularity
Step 5: love Western Europewith a certain popularity, he began to love Western Europe directly. Good projects are very simple, and they are often looted in a small scale. It doesn't matter if the air currency can't attract people. It's easy to find the agent investment channel to help you package the project
Step 6: contact the exchange
generally, they try their best to go to a well-known exchange. If there is no angel round, you can only take the money from aisio. It's not good. It's OK to go to an easy exchange
Step 7: public offering
once on the stock exchange, you will have enough confidence to speak. At this time, we can continue another wave of public offering. Anyway, what we give out are tokens, which can also attract more attention from the market
Step 8: go online
once the funds are sufficient and the quality of the project is good, there will be more mainstream exchanges. Once the mainstream exchange is finished, this is a reliable project
if it is normal, through the above eight steps is the use of blockchain technology of digital currency
but more often is the digital currency issued by indivials, belongs to MLM currency, more common in online private placement, such as the task Gang blocked before

At present, the most successful application of blockchain technology is the digital currency represented by bitcoin, and blockchain also benefits from the deeper development of digital currency
instry insiders said that if a wants to send a bitcoin to B, it first needs to send a transaction request to the blockchain network, provide the addresses of a and B as well as the number of bitcoins sent, and at the same time use the private key to digitally sign the sent information to prove its identity to B. After the information is sent, the miner needs to determine the uniqueness of the transaction, the legitimacy of the address involved in the transaction, the authenticity of the digital signature and the correctness of the number of bitcoins after receiving the information sent by A
after successful verification, the transaction will be added to the block, and each block contains all the transactions in the past ten minutes. Generally speaking, each transaction must be confirmed six times before it can be recognized as a legal transaction on the blockchain. Finally, the block is chained, the transaction is completed, and B receives 1 bitcoin
