Mangata Node
Application-specific blockchain for decentralized exchange, a parachain in Polkadot ecosystem. Implementation includes MEV solution, Proof of Liquidity and no gas economy.
Description
Reliable decentralized exchange (DEX) blockchain - interoperable with other blockchains using Polkadot. The exchange is using a consensus algorithm that solves MEV/frontrunning problems and makes all participants' access to trading opportunities equal.
The design of the blockchain guarantees fixed-fees that provides greater control of trading costs and higher arbitrage opportunity. Assets on the exchange will serve multiple purposes- at the first iteration, they are the block producer’s stake and exchange liquidity at the same time, and more comes later.
Build mangata-node locally
- Install docker
Compilie mangata-node binary and wasms artifacts
- use docker wrapper for cargo to build
mangata-node
./docker-cargo.sh build --release -p mangata-node
build artifacts will be placed in <REPO ROOT>/docker-cargo/release
Generate docker image
You can use build-image.sh script to build & generate docker image
./scripts/build-image.sh mangatasolutions/mangata-node:dev
or you can use already compiled build atributes generated in previous step
SKIP_BUILD=1 BUILD_DIR=./docker-cargo/release ./scripts/build-image.sh
This will generate new local docker image mangatasolutions/mangata-node:dev
Run
In order to run mangata-parachain locally one need to set up both:
- local relay network
- local parachain network
Because of number of parameters is quite troublesome thats why we came up with dedicated dockerized environment.
Set up network using parachain-launch
Dockerized setup requires you to build development docker image mangatasolutions/mangata-node:dev.
Start docker environment using, you need to
cd ./launch
yarn install
yarn gen
yarn uponce started, you can access nodes using port forwards
- 127.0.0.1:9944 - relaychain 1st collator
- 127.0.0.1:9945 - relaychain 2nd collator
- 127.0.0.1:9946 - parachain 1st collator
- 127.0.0.1:9947 - parachain 2nd collator
Docker setup can be stopped using
cd ./launch
yarn downSudo access
Alice is set as sudo account for parachain-launch docker setup
Managata node configuration
There is number of chain configurations available for both development and production environements:
