Stackjoins allow Stackchain to continue moving forward, no matter the current block height, allowing all Bitcoin Plebs to participate. No stack left behind.
A portion of this guide was originally written by Stackchainer "Freeborn."
1. Buy any arbitrary amount of BTC on your preferred exchange.
2. Post a screenshot or snippet of the buy receipt and include the hashtag #Stackjoin. Mempool operators will now be able to find your purchase and add it to the mempool.
3. If you purchase in any other currency other than $USD, please post the conversion to $USD along with your buy receipt. This helps Mempool Operators verify your purchase amount so that it can be correctly added.
4. Stackchain Miners and Mempool Operators use the hashtag #Stackjoin to gather your buy and mark them as "USED". Mempool operators will respond to let you know that your Stackjoin has been added to the Stackchain Mempool. When you get to this step you do NOT need to do anything else. You are done!
5. When a full block is created, you will be tagged along with your fellow plebs and all purchases to be put on the Tip of the Stackchain. Stackchain Mempool Operators will also respond to your original Tweet to let you know that your Stackjoin has been successfully used in an upcoming block.
6. From here, you can enjoy all the benefits of being in the Stackchain elite without having to buy a whole block. Congratulations!
Still confused? We have you covered! Check out this stellar video from highly regarded Stackchain member, Anthony, as he walks you through the entire Stackjoin process.
Besides the above traditional Stackjoin, we also have two other gamified types of Stackjoins that are becoming more and more popular. Think of these types of Stackjoins as "Sidechains" that run within Stackchain. The Stackjoinchain and SJMiner.
Stackchainers stack consecutively just like the normal Stackchain, however there's a fixed stopping point. For example; stacking from 1 to 100. Once stack 100/100 has been reached, the last stacker has the ability to post the completed #Stackjoinchain to the main chain's #StackchainTip or they can use what's available in the Mempool to complete a full block on the main chain.
The SJMiner variation of Stackjoins is a bit more complicated, but adds a little bit more fun, and incorporates Bitcoin blocks. Whomever initiates the #SJMinerchain is referred to as the 'admin' for this Stackjoin. The individual posts $2 with a stack height of 2/60 with #SJMinerTip.
Where this differs from #Stackjoinchain is that with #SJMinerchain, the 'admin' utilizes a random value that will be in a designated target block on the Bitcoin network. This essentially creates a lottery, like Bitcoin mining. Whomever wins this lottery has the privilege to post the final #SJMinerTip to the #StackchainTip and post the block to the main chain. The random value used to select the winner comes from the timestamp second value in the target block. The target block is chosen as the next block after the current block height when the 'admin' posts the final $1 of the 1/60 stack. After this is posted, the second value of the next Bitcoin block is used to determine whom from 1 to 60 is allowed to post the block to the main chain. The funds from the Mempool may be used to complete the block if needed. This 'miner' has 24 hours to post the block before it's forfeited to another user.
Some additional variations to this exist. As shown here, you'll see this was a SJMiner Big Block variation where each transaction from 2/10 needed to be $200.
