Taichia airdrop solution is based on the "secure the bag" solution. All of the airdrop addresses will be organized as a tree. You need to pay the XCH or token you want to airdrop to the root address of the tree. This guarantees your fund is 100% safe and no one can change the airdrop addresses. Taichai will split the tree into spend bundles. To speed up your airdrop, you may want to add a transaction fee (unwind fee) for each bundle. You need to pay all fees (in XCH) to another address. Taichia will only process your airdrop when you finished the transaction for both addresses.
