        ​​​​​​​​Eric Hop -
        ​​​​​​​​The bundle moves the 2.78 pi from an address to that same address.
        ​​​​​​​​It's completely according to the rules.
        ​​​​​​​​See bundle here:
        ​​​​​​​​https://iotasear.ch/bundle/HGCKTQQOUJTCTYBX9Q9EKCGHTCWPRLXIBBR9SXACEZJLQVZYQYPGHKZLLLVKPHDX9NPUAI9EOWVCGQTGC
        ​​​​​​​​All validations are met:
        ​​​​​​​​* The one that says that the sum of the inputs and outputs must be zero? Yep.
        ​​​​​​​​* The one that say that end balance for any address cannot be negative? Yep.
        ​​​​​​​​* The one that says that it needs to be properly signed? Yep.
        

      • 在 IOTA Tangle 的 use case：
        • How to send data payload and funds in a secure/immutable way?
        • A sender can be verified by spending N iotas from an address (even with 0 balance) and sending them back to the very same address. – Come-from-Beyond
        • Right, preferably with a zero-balance address, though special procedures allow to spend more than once without much risk. – Come-from-Beyond
    • iota.lib.js/isBundle
      • Checks if the provided bundle is valid. The provided bundle has to be ordered tail (i.e. currentIndex: 0) first. A bundle is deemed valid if it has:
      • Valid transaction structure
      • Correct currentIndex, lastIndex and number of bundle transactions
      • The sum of all value fields is 0
      • The bundle hash is correct
      • Valid signature
