The optimized luck2 wallet has been released, which does not affect the nodes and wallets. The updated content are as follows:
1 The password input of the windows wallet is displayed as ***
2 Display the plotting status.

At present, luck2's system running well, and the source code will be opened in the near future.

We have synchronized the tokens before the 388000 block of Luck v1 to the Luck v2 by pre-mining.

We are not clear about the withdrawal of tokens in the exchange. Please consult the specific person in the exchange.

In addition, some members asked via email when to transfer tokens before the 388000 block in luck to luck2.

We will start it today, and it may be completed within one week.

thank you so much for your suggestions.

1 Since luck2 is optimized based on ethereum in software engineering, some designs in ethereum are introduced, such as trying to access DNS discover network. currently all.mainnet.fortdisco.net does not exist, but it does not rule out that some automatic discovery network strategies will be activated when there are more nodes in the future.

2 The problem of password input in plaintext, we have recorded it, and will fix it in next week. If you are worried about security, it is recommended to use the linux wallet first.

3 Discord was established by other community members, and we don't know the specifics of the operation. For the time being, we can't give more opinions. We are more concerned about the stability of the core system of the project.

4 The size of the windows is about 2 times that of the linux, not 10 times. Which contains part of the GUI framework and GUI components. There may not be many unnecessary files.

The second round of testing has been released, and the testing method is the same as the first round.

thank you so much for your suggestions.

we have also considered the issue of exchanges very carefully, but to reduce the loss of investors, we do not recommend that large transactions occur in the early stages of system for instability.

We upgraded to luck v2 also to elimate the  advantages of GPUs , because luck’s core design is to mine by luck, eliminate public pools, and realize "more nodes = more decentralization", which requires more nodes to participate in a low-cost way.

There are many technical details that need to be considered against GPUs, so we are gradually improving the parameters to strive for more nodes to participate in mining in a low-cost, non-cooperative manner within a long time after the mainnet launched.

We will start the second round of testing as soon as possible within these few days, please be patient.

in windows wallet, you can click "plot", then fill in the correct parameters and click "submit".
the plotting process will take one hour.

But the first round of testing have been closed. you can wait for the second round of testing, which will be started on February 13, 2021

The second round of testing will be started on February 11, closed on February 15, 2021.(the second round of testing will optimize some parameters.)

The miannet will be launched on February 18, 2021.

At present, luck2-2POC's testnet is relatively stable. We have released the Windows GUI version of the mining program on the website. The testnet is still in progress. Welcome to to join in the test.
As the requirements for hard disks are reduced to 10G-60G, you do not need to carry hard disk capacity information when sending emails.

The Windows GUI of the testnet will be released within 2 days.

you can download the latest linux wallet at https://lucknet.club/wallets-luck2-test/luck2

For detailed usage, please see https://github.com/luck-coin/luckcoin/blob/master/wiki/miner_test.md

The test chain has been restarted, and the hard disk capacity requirements have been reduced to between 10G-60G. Please download the latest wallet from the official website and start mining again. The nodes that have been plotting do not need to re-plotting.



If everything goes well, the mainnet will be launched in early February.



Good suggestions.

In response to the two days of testing and after technical discussions with the test miners, the following adjustments will be made to the test:
Without reducing the security of the system, the hard disk capacity requirement of a single node is reduced from more than 1T to between 10G-60G to meet the needs of a wider range of miners. Of course, larger capacity will bring additional, less obvious advantages.
The system for adjusting parameters is currently being tested, and the test chain will be restarted within 1 day.

In addition, the technical problems encountered by some miners during the plotting process are shared as follows:
1 Crash occurred during ploting.
Some miners perform plotting on multi-core machines and set the size of a single file to be too large, which leads to insufficient memory during the plotting process and crashes.
If crash occurs, it is recommended to delete all the hash files in the plotting directory and reset the parameters for plotting.

2 Cannot mine normally after plotting ends
There are two possible reasons for the failure of mining after plotting.
2.1 The wallet address used in the plotting process is inconsistent with the mining process.
2.2 Insufficient hard disk capacity.

1、You should update your wallet first;
2、in your console，If you see {"code":0,"msg":"ok","current":10,"total":500,"name":"xxxxxx_xxxxx_xxxxx"},plotting is ok. else you should check your  plotting directory.
 
 
 

some users have emailed to us, the node has not synchronized blocks. This is because we have updated wallets. Please download the latest linux wallet through the official website to participate in the test. thank you.

If you have completed plotting, you only need to update the wallet software, no need to repeat plotting.

for example
miner.startPlot("0x5f7c7d777de1f62bc7bcae425a136df52b858fa84e31e64bf5",0,"256MB","256GB")

The testnet of luck2-2poc has been deployed, and the test wallet has been published to the official website.
For some issues we have received by emails, we reply as follows:

1 Whether the test supported to windows system?
This testnet mining is only for linux machines, and windows will be provided after the mainnet launched.

2 Why do i need a hard drive of 1T and above?
The principle of the POC consensus mechanism is to write a large number of hash values ​​in the hard disk in advance, and this process is called plotting. When mining, it searches the hard disk for "answers" instead of consuming a lot of calculations. 2POC as an upgrade of the POC consensus, still requires plotting.
At present, our optimization has reduced the consumption of some hard disks. In theory, hard disks with more than 256GB can also participate in mining, compared with large-capacity hard disks, there may be a slight disadvantage.

3 Is there a difference in wallet address between luck2-2poc and luck-2pow? Is there any replay protection?
Luck2-2poc and luck-2pow use the same format on the wallet address. luck2-2poc realizes the replay protection of transactions by setting different chainID.

4 What do the holders of luck-2pow need to do in luck2-2poc?
At present, luck2-2poc and luck-2pow use the same format on the wallet address, but different networks, so you only need to save the keystore file and private key. The same address will receive the same token compensation after the luck2-2poc mainnet launched.

5 How to participate in the test?
Please refer to the introduction in https://github.com/luck-coin/luckcoin/blob/master/wiki/miner_test.md.

6 How do the accounts participating in the test get rewards in the mainnet?
We give priority to the 800 rewards for the 20 addresses that register first, and 400 rewards for the 30 addresses that register subsequently. For registered addresses, if there is no mining record in the test network, the corresponding rewards will be cancelled.
At present, we have received some test registration emails. We have been waiting for your registration and participation before the test is completed.

After Luck-2pow reaches the height of 388000 block, Luck-2pow will be upgraded to Luck-2poc. In order to protect the interests of the Luck-2pow community and miners, we will make equal compensation for the address holding luck-2pow after luck-2poc launched.

When the block height reaches 388000, these accounts have Luck-2pow, if you have any questions, please email us in time.

The holding accounts are as follows：https://github.com/luck-coin/luckcoin/blob/master/wiki/luck-2pow.md

Publicity: The test file of Luck-2poc has been released. You can click https://github.com/luck-coin/luckcoin/blob/master/wiki/miner_test.md to view the details.

Recruitment of Luck-2poc test miners is in progress, Luck-2poc official test time: January 15, 2021, test period: 2 weeks.

At present, we have received emails from miners who want to participate in the test, and at the same time, please send us the wallet address and hard disk capacity by email so that we can do data analysis. It is also the basis for later payment of rewards.
