Official Javascript implementation of AI Network Blockchain.

Tracker

Tracker server is required by new peers who wish to join the AIN network. Each peer is sent the ipaddress of 2 other nodes in the network. These nodes then gossip information through the network of all transactions and blocks.

NOTE: Tracker Server must be started first before starting any blockchain node instances

Running without Docker

Local

Clone this repository and install npm packages

git clone https://github.com/ainblockchain/ain-blockchain.git
cd ain-blockchain/tracker-server/
yarn install
cd ..

Run Tracker server

node tracker-server/index.js

On Google Coud Platform (GCP)

Deploy code (in common with Node server)

gcloud init
sh deploy_gcp.sh {dev|spring|summer} <YOUR_GCP_USER_NAME>

Set up Ubuntu machine (if it's on a new VM)

sh setup_ubuntu.sh

Copy files to a sharable folder & install npm packages

sh setup_tracker_gcp.sh

Start tracker server job

cd ain-blockchain/
sh start_tracker_gcp.sh

Client APIs for development and debugging

Tracker health check

GET http://<ip_address>:5000/

Node status check

GET http://<ip_address>:5000/peer_nodes

Node

Operates a single peer node instance of the AIN blockchain. A single blockchain node instance processes incoming transaction requests and maintains a local copy of the entire blockchain. The blockchain node first queries the tracker-server for ip addresses of other peers, and then syncs its local blockchain to the network consensus blockchain. If a node is included in the whitelist and has staked appropriate amount of AIN, it will then take part in the consensus protocol.

Running without Docker

Local

Clone this repository and install npm packages

git clone https://github.com/ainblockchain/ain-blockchain.git
cd ain-blockchain/
yarn install

Run blockchain nodes

ACCOUNT_INDEX=0 HOSTING_ENV=local DEBUG=false node client/index.js
ACCOUNT_INDEX=1 HOSTING_ENV=local DEBUG=false node client/index.js 
ACCOUNT_INDEX=2 HOSTING_ENV=local DEBUG=false node client/index.js 
ACCOUNT_INDEX=3 HOSTING_ENV=local DEBUG=false node client/index.js 
ACCOUNT_INDEX=4 HOSTING_ENV=local DEBUG=false node client/index.js

Before starting node jobs, remove existing blockchain files and logs if necessary:

rm -rf blockchain/blockchains logger/logs

The default size of the validator whitelist is 5. Set NUM_VALIDATORS environment variable when running the first node if you'd like to run different number of validator nodes than 5.

How to run tests

npm run test_unit
npm run test_smoke
npm run test_integration

On Google Coud Platform (GCP)

Deploy code (in common with Tracker server)

gcloud init
sh deploy_gcp.sh {dev|spring|summer} <YOUR_GCP_USER_NAME>

Set up Ubuntu machine (if it's on a new VM)

sh setup_ubuntu.sh

Copy files to a sharable folder & install npm packages

sh setup_node_gcp.sh

Start Node server job

sh start_node_gcp.sh {dev|spring|summer} <SERVER_INDEX>

How to run tests

npm run test_unit
npm run test_smoke
npm run test_integration
