Currently, Scorex's distribution contains one example of blockchain system built on top of Scorex: TwinsCoin.
Twinscoin is a hybrid Proof-of-Work(PoW) and Proof-of-Stake(PoS) cryptocurrency with 1:1 correspondence between PoW and PoS blocks. The main goal is to protect the hybrid chain against majority of hashing power being adversarial.
The main characteristic of the implementation are:
-
The use of the Twinscoin consensus protocol;
-
A Bitcoin-like transaction model with a transaction having multiple inputs and outputs (with no scripts, however);
-
Persistence through the IODB versioned key-value database.
To run, you need to have Java8 and SBT (Scala Build Tool) installed.
In the terminal, run sbt, and then type the following commands in the SBT shell:
> project examples> runMain examples.hybrid.HybridApp src/main/resources/settings.conf
This will create and run a node with the given settings. To create and run more nodes, repeat the steps above using the other setting files (e.g. settings2.conf, settings3.conf, ...) in the src/main/resources/ folder.
Note to MacOS users: The 127.0.0.X loopback addresses (for X > 1) are disabled by default in MacOS. Therefore, the creation of nodes with settingsX.conf (for X > 1) fails. To prevent the failure, enable the addresses.
You can interact with the nodes you created through a web browser. For the node created with settings.conf, visit localhost:9085.
