I skimmed the thread, so I apologize if my questions were asked or answered.
I love how Dash is aggressive in S. America. So much of crypto is pure speculation (buy and hope it goes up, then sell to somehow else). So see easy applications and actual retailers embracing it, is kind of the dream for crypto (or should be)
With Dash, does the blockchain/confirmations work the same? Is there a risk for doublespend like bitcoin? If paying at a retail outlet, are you made to wait until the transaction has a confirmation? (I saw the video of the girl paying for chicken and it seemed fast, but I've done Dash transactions where it seemed like sometimes it can be a few minutes between confirmations)
With Dash previous update v0.13 it became possible for Dash to enable InstantSend on small transactions (4 input amounts or less)
automatically with no additional costs. This will get you :
Instant payment with confirmation within a few seconds
Available and spendable by receiver right away
Locked against double spending
Note : This is currently about 90% of the transactions on the Dash network.
Dash also has the optionally InstantSend to be used on any transaction for a small fee, regardless of the size of transactions.
Available right away and spendable by receiver after 1 proof of work confirmation, if i understand it correctly
Locked against double spending
Then you have the Dash transactions that contain more then 4 inputs and are not send through InstantSend, those transactions
will get confirmed through proof of work and are normally considered secure after 6 confirmations. They dont have a specific
locking mechanisme and are in principle the same as how Bitcoin does its confirmations, but then 4 times faster then Bitcoin.
With Dash next update v.0.14 there will be LLMQ-based (Long Living Masternode Quorums) InstantSend.
Keep an eye out on its release as that should provide you wilth more specifics.

after just 1 transaction confirmation (instead of the normal 6 transaction confirmations).
