Ⅰ How long does blockchain mapping take?

Blockchain mapping takes about 2 to 3 months
Blockchain mapping is equivalent to your old currency wallet and Establish a corresponding relationship between the new currency wallets and tell the project party how many old coins you have. After the mainnet goes online, the project party will need to give you the same number of new coins.
Blockchain is a database with a data "hash verification" function. Blocks are data blocks. Data blocks are combined into a chain structure in chronological order, and cryptographic algorithms are used to collectively maintain the reliability of the database in a distributed accounting manner. All data blocks are connected in chronological order, forming a blockchain.

II What is EOS wallet mapping?

In recent days, Binance, Huobi, and ImToken have successively announced that they will support EOS wallet mapping. So what is this so-called mapping? What's going on, what will be the consequences if you don't map it, and how to map it specifically, here is a brief introduction.

EOS is a new generation of underlying blockchain platform developed by block.one, which is famous for its fast transaction speed. (claimed to be millions per second), famous for supporting smart contract development, it is currently still in the ICO stage, and its main chain development has not yet been completed. The ICO will end on June 1, 2018, and its main chain and wallet will also be online simultaneously. . Because the main chain does not yet exist, current EOS holders do not hold the real EOS currency, but the token, which is a certificate issued by the EOS project party that proves that you can own the native EOS currency in the future. This certificate can only be obtained by going to the main chain for exchange operation when EOS goes online. This exchange process is actually mapping. Currently, EOS tokens are issued based on Ethereum, and almost 90% of the current tokens are Adopt this model and issue based on Ethereum.

24 hours after the crowdfunding ends, all EOS tokens on Ethereum will terminate trading, and token holders need to create the EOS mainnet address and private key, and link the private key to Ethereum, so that when the EOS main network is deployed, a corresponding number of real EOS coins will be generated based on the number of Ethereum tokens. The link process here requires calling a smart contract and sending A special transaction is completed. (One thing to note is that the private key must be kept, otherwise your EOS will be lost) If the token holder does not complete the mapping operation before this time, the tokens in his hands will It will be invalid and worthless.

At present, all major exchanges will support the mapping operation, and the ImToken wallet will release version 1.4.3 on 3.24 to support the mapping operation.

Ⅲ In Do I need to map the eos coins I bought on Huobi and mention the wallet?

No, it’s usually a big exchangeExchange will do the mapping for you. EOS can be understood as Enterprise Operation System, a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introduced to achieve performance expansion of distributed applications. Note that it is not a currency like Bitcoin and Ethereum, but a token released based on the EOS software project, called Blockchain 3.0.

(3) What is the role of blockchain mapping? Extended reading:

Previously, EOS had almost the entire currency circle involved due to the super node election campaign. : Exchanges, mining pools, and big Vs are coming one after another, and even the famous overseas "Wenzhou Gang" has rushed to enter the market with billions of assets. This situation once drove the price of EOS to rise steadily and call for sales. Non-small data show that in mid-to-late March, EOS was in a low-level hovering period. On March 19, the price was only US$4.02, and the total market value of EOS was US$3 billion.

As we enter April, more teams and individuals continue to pour into this annual drama in the currency circle. On April 11, AntPool announced its participation. On the 20th, Erye Bao arrived. On the 24th, the cryptocurrency exchange Bitfinex and Huobi Mining Pool also announced their participation in the super node election. Suddenly, EOS formed a wave of strong momentum, boosting the price to rise. By April 30, the price of EOS surged to US$20.05, and its market value reached US$16.5 billion.

In May, the situation began to change. In line with the downturn of the digital currency market, EOS also started a downward trend. By May 31, the EOS price had fallen to a small bottom, only $11.94. The following week, as the original mainnet launch date of June 8 approached, the price of EOS bucked the trend and rose, with the price rising to $14.29 that day.

Unexpectedly, on June 8, because 1/3 of the participating nodes voted against it, the mainnet launch failed and had to be postponed. On June 10, the launch was launched again, but failed again because the online voting rate was only 1.77%, which did not reach the 15% voting rate required for the mainnet to go online.

This situation was quickly transmitted to the market price. Within just a few days, the price of EOS went downhill again, falling from US$14 to US$13 to US$11. On June 14, it even broke through Ten”, sliding to $9.68. As of June 28, the price of EOS has fallen by nearly 60%.
