[ANN] Askcoin (ASIC-resistant) is a decentralized Q&A and prediction platform.

@Twinkledoe,

If you are familiar with C++ language, you can refer to the 'proc_topic_expired' function in blockchain.cpp file (https://github.com/lichuan/askcoin/blob/master/src/blockchain.cpp):

Code:

bool Blockchain::proc_topic_expired(uint64 cur_block_id)
{
    if(cur_block_id < (TOPIC_LIFE_TIME + 2))
    {
        return true;
    }
    
    if(cur_block_id > (2 * TOPIC_LIFE_TIME + 1))
    {
        m_rollback_topics.erase(cur_block_id - (2 * TOPIC_LIFE_TIME + 1));
    }
    
    m_rollback_topics.erase(cur_block_id - (TOPIC_LIFE_TIME + 1));
    auto &topic_list = m_rollback_topics[cur_block_id - (TOPIC_LIFE_TIME + 1)];
    
    while(!m_topic_list.empty())
    {
        std::shared_ptr<Topic> topic = m_topic_list.front();
        uint64 topic_block_id = topic->m_block->id();
        
        if(topic_block_id + TOPIC_LIFE_TIME < cur_block_id)
        {
            m_topics.erase(topic->key());
            topic_list.push_front(topic);
            std::shared_ptr<Account> owner = topic->get_owner();
            
            if(!owner)
            {
                return false;
            }

            if(owner->m_topic_list.empty())
            {
                return false;
            }

            std::shared_ptr<Topic> topic_in_owner = owner->m_topic_list.front();

            if(topic != topic_in_owner)
            {
                return false;
            }

            uint64 balance = topic->get_balance();
            
            if(balance > 0)
            {
                m_reserve_fund_account->add_balance(balance);
            }
            
            owner->m_topic_list.pop_front();
            m_topic_list.pop_front();

            for(auto &p : topic->m_members)
            {
                p.second->leave_topic(topic);
            }
        }
        else
        {
            break;
        }
    }
    
    return true;
}

When a topic expires, its balance will be transferred to the 'reserve_fund' account.

Today, we made our seventh donation of ASK coins and donated 50 billion ASK coins. So far, 350 billion ASK coins has been donated. We promise that we will gradually donate ASK coins in our hands until the number of ASK coins we hold as a percentage of total supply is reduced to 10 percent or less.

You can check this donation by entering the following block hash in the block explorer's search box:

Block hash: AAAc3aox9H8QAP4mD5/NrRKA3qV3lVDgb2pXQS/qO2Q=
Block height: 127859
Block explorer: http://explorer.askcoin.me


Q: What can I do to get ASK coin?
A: There are 3 ways to get it:

• After registering the account, you can import the private key into the mobile app and receive a reward by answering questions from others.
• Run the full node to mine and get the miner's earnings.
• Buy ASK coin through an exchange or person-to-person transaction.

Today, we made our 8th donation of ASK coins and donated 50 billion ASK coins. So far, 400 billion ASK coins has been donated.
Now we have less than 10% of the total supply of ASK coins.

You can check this donation by entering the following block hash in the block explorer's search box:

Let's go,

In fact, You guys can post anything on askcoin platform, not limited to questions, answers,
there is no restriction on what can be published and no one can censor or block what you publish.

[lichuan]

Hi guys,

If you want to run askcoin's full-node on Windows, you can install linux OS in a virtual machine such as VMware,
and run full-node in that environment.

Q: What can I do to get ASK coin?

• After registering the account, you can import the private key into the mobile app and receive a reward by answering questions from others.

The title of this topic is changed, because we plan to add event prediction and betting features to Askcoin, which can predict sports events or political events to reflect the actual probability of an event in real time. the event must be clear, no ambiguity, the final result of the event is either TRUE or FALSE, so the players can freely buy TRUE or FALSE to predict whether an event will happen, and finally the witness will publish the result, and each participating account will be settled by the system.

To be honest, I don't like centralized exchanges. They charge a lot of money and can decide when to delist a coin in any way they want. I don't think this is the direction that blockchain should go. Blockchain should give everyone a more free life!  So in the future, we may develop truly free de-centralized exchange on askcoin.

[alano83]

I think like you, these exchanges are just ruining the crypto market ... they only value those they like and not who they really deserve. if I can advise you in my opinion if you can make a simple game like slot or roulette where you can bet the ask you would really make a bang;)

Yes, we will add prediction and betting feature on askcoin, but we need to implement decentralized exchange on askcoin first.

[lichuan]

From now on, the main site of askcoin will use HTTPS protocol to prevent man-in-the-middle attack, but the block explorer and registry string generator sites still use http, because http is faster, and these two sites do not involve package informations and links of fullnode and mobile app, so there is no factor affecting security. So, there are three sites for you to visit:

https://www.askcoin.me
http://explorer.askcoin.me
http://generate.askcoin.me

[lichuan]

FYI:
   The reason why we want to develop a separate blockchain dapp is that we can't implement all its functions on the existing platform. For example, you can't implement a dapp like askcoin on the platform of Ethereum, because the mobile dapp is connected to the fullnode through websocket, when the block of the fullnode is reorganized or reverse, the mobile dapp also needs to deal with the corresponding complex logic which can't be controlled in detail on Ethereum. In addition, the nodes of Ethereum occupy a lot of disk space, so it's not easy for people to run its fullnode.

   We hope askcon will give people some thoughts on where the blockchain industry should go. Askcoin can also bring people real freedom, because it is a really valuable decentralized use case.

[lichuan]

Now, for security reasons, all of askcoin's web addresses have been replaced with HTTPS.
You can safely access the following links:

https://www.askcoin.me
https://explorer.askcoin.me
https://generate.askcoin.me

How do we know who to ask and whether they are capable of answering the question?

How do we know who to ask and whether they are capable of answering the question?

When you want to create a question, you need pay some amount of ASK as reward, when someone sees your question and replies to you, if you're satisfied, you can decide to reward that response, you can also decide how much to reward on each reply.

In the future, we will also develop a built-in decentralized exchange that will allow users to initiate P2P trade directly on the askcoin app
