For the first ten years, Dash had only one chain: a Bitcoin-based, proof-of-work, UTXO chain prioritized for payments.
Masternodes provided special services including instant transactions, high security, and privacy, but everything was still done on one layer.
With the launch of the Evolution platform this year, Dash now has another chain: a loosely Cosmos-based, proof-of-stake (still run by the same EvoNodes who provide masternode services for the payments chain), account-based chain prioritized for data and decentralized applications.
Why maintain two separate chains if it’s essentially the same network, same validators, same currency?
1: Two Different Use Cases
First, the two chains are primed for two very different use cases. Without any advanced privacy functions like zero-knowledge proofs, the UTXO model is inherently more private the account-based model. It also is inherently much easier to scale to high transaction volumes.
Having a dual security model (miners and masternodes) also offers the highest and most robust security and liveness guarantees, which are particularly important for a financial network where people need to have consistent access to their money.
The account-based model is able to achieve global state, which is very important for decentralized applications, and necessary for the kind of needs the Evolution platform has. A smaller subset of the network (EvoNodes) also runs Evolution so as to keep decentralized data storage costs lower, and having this on a separate chain from the main payments chain avoids passing that trade-off to users of the monetary network.
And finally, at very high volumes of transactions with large amounts of data, some advanced scaling techniques like sharding may become necessary. These introduce some trade-offs such as latency, and keeping this to the data chain can avoid visiting them on all use cases.
2: Avoids Disruption
Second, a new chain avoids disruption that would be caused by serious changes to the original chain.
Dash has been building a global ecosystem of decentralized money and payments for the past ten years, and introducing severe changes to the payments chain would disrupt this for users, business partners, developers, and more.
3: Risk Mitigation
And finally, having two chains can be beneficial for risk mitigation. In the past, sudden spikes in usage for data use cases have disrupted the ability for Bitcoin and Ethereum users to access their money.
With Dash, a suddenly-popular DApp pushing the Platform chain to its limits would have no effect in preventing users of the Core chain to access and user their money as they normally do.
We believe that Dash’s two-chain solution, segmented by use case, can provide many benefits without fragmenting the ecosystem as is a risk of popular second-layer scaling approaches.

1 dash is worth 120 HIVE at the moment

Interesting! Though we should use a Maya interface like LeoDEX to go between Hive and Dash.
to be honest, never really touched the LEO interfaces on HIVE. that is why i chose the stealthex route.
do i get more HIVE for DASH, if i use maya interface?
Possibly, but the big thing is it's decentralized rails, and Dash holders can earn transaction fees.
We have $DASH in our portfolio.
Also we know where to spend our $DASH
But this content was very interesting.
Thanks for share more about yourself in #Hive
Awesome :) !BBH !DOOK
Haha thanks
You just got DOOKed!
@bradleyarrow thinks your content is the shit.
They have 36/60 DOOK left to drop today.
Learn all about this shit in the toilet paper! 💩
Super interesting, didn’t know all of this about dash. I’ll have to look into evolution more…
!BBH
Cool, read the linked article at the bottom, it explains most things well.
Dual security model sounds futuristic 😎
I'm on it ✌️
It's very intricate and well-designed.
That’s very interesting. I’ll have to look into the dash ecosystem. It has been many years since I last had a look at it.
Do you have any good business use-case examples you’re proud of?
Money. Living 100% off of decentralized crypto. It's possible in much of the world today with Dash.
There are many other applications for the Evolution platform though, we're working on a video series.
Thanks, great to know you’re actually trying to solve the money problem, rather than a investment token
