OKP4 is a public dPoS layer 1 specifically designed to enable communities to trustlessly share data, algorithms and resources to build the Dataverse - An open world where everybody can create or participate in custom ecosystems (with common governance mechanisms, sharing rules, business models...) to build a new generation of dApps way beyond Decentralized Finance.

The protocol

okp4d is the node of the OKP4 network built on the Cosmos SDK 💫 & Tendermint consensus, and designed to become a hub of incentivized data providers, developers, data scientists & users collaborating to generate value from data and algorithms.

Read more in the introduction blog post. For a high-level overview of the OKP4 protocol and network economics, check out the white paper.

Want to become a validator?

Validators are responsible for securing the okp4 network. Validator responsibilities include maintaining a functional node with constant uptime and providing a sufficient amount of $KNOW as stake. In exchange for this service, validators receive block rewards and transaction fees.

Supported platforms

The okp4d blockchain currently supports the following builds:

Platform	Arch	Status
Darwin	amd64	✅
Darwin	arm64	✅
Linux	amd64	✅
Linux	arm64	✅
Windows	amd64	️🚫 Not supported

Note: as the blockchain depends on CosmWasm/wasmvm, we only support the targets supported by this project.

Releases

All releases can be found here.

okp4d follows the Semantic Versioning 2.0.0 to determine when and how the version changes, and we also apply the philosophical principles of release early - release often.

Docker image

For a quick start, a docker image is officially available on Docker hub.

docker pull okp4/okp4d:latest

Get the documentation

docker run okp4/okp4d:latest --help

Query a running network

Example:

API_URL=https://api.devnet.okp4.network:443/rpc
WALLET=okp41pmkq300lrngpkeprygfrtag0xpgp9z92c7eskm

docker run okp4/okp4d:latest query bank balances $WALLET --chain-id okp4-devnet-1 --node $API_URL

Create a wallet

docker run -v $(pwd)/home:/home okp4/okp4d:latest keys add my-wallet --keyring-backend test --home /home 

Start a node

Everything you need to start a node and more is explained here: https://docs.okp4.network/docs/nodes/run-node

MONIKER=node-in-my-name
CHAIN_ID=localnet-okp4-1

docker run -v $(pwd)/home:/home okp4/okp4d:latest init $MONIKER --chain-id $CHAIN_ID --home /home 

This will create a home folder, you can then update the config/genesis.json with one of this ones : https://github.com/okp4/okp4d/tree/main/chains/

Join a running network

Set persistent_peers in config/config.toml file.

Then start the node

docker run -v $(pwd)/home:/home okp4/okp4d:latest start --home /home

Developing & contributing

okp4d is written in Go and built using Cosmos SDK. A number of smart contracts are also deployed on the OKP4 blockchain and hosted in the okp4/contracts project.

Prerequisites

• install Go 1.19+ following instructions from the official Go documentation;
• use gofumpt as formatter. You can integrate it in your favorite IDE following these instructions or invoke the makefile make format-go;
• verify that Docker is properly installed and if not, follow the instructions for your environment;
• verify that make is properly installed if you intend to use the provided Makefile.

Makefile

The project comes with a convenient Makefile that helps you to build, install, lint and test the project.

$ make help

    proto-build         Build all Protobuf files
    proto-gen           Generate all the code from the Protobuf files
  Release:
    release-assets      Generate release assets
  Help:
    help                Show this help.

This Makefile depends on docker. To install it, please follow the instructions:
- for macOS: https://docs.docker.com/docker-for-mac/install/
- for Windows: https://docs.docker.com/docker-for-windows/install/
- for Linux: https://docs.docker.com/engine/install/

Build

To build the okp4d node, invoke the goal build of the Makefile:

make build

The binary will be generated under the folder target/dist.
