 OriginTrail Decentralized Knowledge Graph (DKG), hosted on the OriginTrail Decentralized Network (ODN) as trusted knowledge infrastructure, is shared global Knowledge Graph of Knowledge Assets. Running on the basis of the permissionless multi-chain OriginTrail protocol, it combines blockchains and knowledge graph technology to enable trusted AI applications based on key W3C standards.

 Knowledge Assets are verifiable containers of structured knowledge that live on the OriginTrail DKG and provide:
-- **Discoverability - UAL is the new URL**. Uniform Asset Locators (UALs, based on the W3C Decentralized Identifiers) are a new Web3 knowledge identifier (extensions of the Uniform Resource Locators - URLs) which identify a specific piece of knowledge and make it easy to find and connect with other Knowledge Assets.
-- **Ownership - NFTs enable ownership**. Each Knowledge Asset contains an NFT token that enables ownership, knowledge asset administration and market mechanisms.
-- **Verifiability - On-chain information origin and verifiable trail**. The blockchain tech increases trust, security, transparency, and the traceability of information.

 ### Local Network Setup
 
 <br/>
 
 First, clone the repo:
+
 ```bash
 git clone https://github.com/OriginTrail/ot-node.git
 cd ot-node
 ```
 
 Install dependencies using `npm`:
+
 ```bash
 npm install
 ```
 
+Create the .env file inside the "ot-node" directory:
+
+```bash
+nano .env
+```
+
+and paste the following content inside (save and close):
+
+```bash
+NODE_ENV=development
+RPC_ENDPOINT_BC1=http://localhost:8545
+RPC_ENDPOINT_BC2=http://localhost:9545
+```
+
 Run the Triple Store.
 
 To use default Triple Store (`blazegraph`), download the exec file and run it with the following command in the separate process:
+
 ```bash
 java -server -Xmx4g -jar blazegraph.jar
 ```
 
 Then, depending on the OS, use one of the scripts in order to run the local network with provided number of nodes (minimal amount of nodes should be 12):
 
 **MacOS**
+
 ```bash
 bash ./tools/local-network-setup/setup-macos-environment.sh --nodes=12
 ```
