  (That is a type "K" with positive or negative value)
  (It's close to the IOTA community plan to implement ?)

curl http://HOST_URL \
-X POST \
-H 'Content-Type: application/json' \
-d '{"command":"send_token",uuid": "9JVXCXMFAMKLUQQCDACSWJVDLH","receiver":"9JVXCXMFAMKLUQQCDACSWJVDLH","value":"100","msg":"HELLO"}'

• Off-tangle data:
  About the off-tangle date, we plan to store in the IPFS or just write content into the Tangle e.g:iota-storage/storage-web, any suggestion ?

• Conflict transaction:

• A clear definition about conflict transaction on Tangle?

  • Duplicate transaction hash (possible?)

    Yes.

  • The code section of IRI to handle the conflict transaction ?
    Yes.

  • Can conflict transactions be defined by user? I think it should be.Beacuse different application needs different definition of conflict transactions.
    No.

• Tangle

• Does node(IRI) choose the max weight(cumulative weight) transaction in conflict transactions?

  Yes.

• Does MCMC deal with "lazy tips"? I mean the probability of choosing "lazy tips" is low when use MCMC to choose tip.

  Don't know.

• Transaction in tangle never be deleted.

  Yes.

  But it will be merged when node snapshots.
