Hi. It's fairly advanced from Bitcoin and developing fast, some good vids covering most aspects though:
https://www.dashpay.io/dash-video-series/EDIT: Vid 5 covers Darksend and InstantX.
Evolutions not out yet and details are sketchy but the developers have been rock solid on living up to claims so far. It would take a bit of explaining and tbh the vids do a far better job than I can, once you've got your head around them the post of Evans I quoted in the post above yours should make a lot more sense.
I watched the vids. I'm still not sure how InstantX manages to be secure though...
I kinda understand how it works, but not sure how the security works.
This is how I think bitcoin works:
the big problem in cryptocurrencies is that there is lag on a network. If there wasn't lag, we could just all send transactions. Everybody would see the first transactions and an attempt at double spend would be automatically ignored.
But there is lag (latency) on a network, so we need some kind of synchronization. Therefore, bitcoin groups transactions in "blocks". These blocks are propagated in the network. Once a block is mined, the transaction has one confirmation. However, it's still possible someone mines on an older version of the chain, so for bigger transactions, it's better to wait for more (2, 3, ...) confirmations to be sure it's included in the longest chain.
(correct me if I'm wrong)
This is how I think DASH works:
There are decentralized oracles that are deterministically chosen and vote on "locking" a transaction. When the oracles decide that a transaction is locked, miners can't mine a double spend because all nodes
(masternodes or all nodes?) reject transactions that are in conflict with the locked transaction. If a block is mined with a conflicting transaction, that block is rejected by the nodes and other miners
(but how can you force miners to reject a block? ).
Also, I'm not clear on what happens with the double spend transaction if that one also get locked by other masternodes that ignore the first transaction. After all, your masternode get a fee when you vote for a transaction
(I think?), so you have an incentive to vote for the double spent transaction.
is it possible that there is a competing locked transaction? So as you can see, I still have some questions about the security of InstantX. i marked them so it's easier to address them.
Btw, this thread's been getting hammered by trolls for a while, usually folks post a few links with responses to the repetitive FUD but I'd suggest checking the first 20 or so pages of this thread and their post history if you come across them and have any doubts.
I don't know about them. I just arrived... I guess any disruptive tech puts some other people at a loss, making them angry
I guess I'll notice them and put them on ignore
